The general instructions are given in this section and the option-specific instructions in the applicable chapter. In addition to this manual: • For ACS880 single drives, see the drive hardware manual • For ACS880 air-cooled multidrives, see ACS880 multidrive cabinets and modules safety instructions (3AUA0000102301 [English]) • For ACS880 liquid-cooled multidrives, see ACS880 liquid-cooled multidrive cabinets and modules safety instructions (3AXD50000048633 [English]). WARNING! The functions described in this manual do not disconnect the voltage of the main and auxiliary circuits from the drive. Do not do work on the drive, motor cable or motor when they are energized. Before you start the work, do the steps in section Electrical safety precautions (page 11). WARNING! If a short-circuit occurs in the output stage of the drive, the STO function does not prevent the intermediate DC current from flowing through and heating up the motor. The system integrator must take this into account when planning the protection of the installation. 10 Safety instructions

These electrical safety precautions are for all personnel who do work on the drive, motor cable or motor. WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the equipment can occur. If you are not a qualified electrical professional, do not do installation or maintenance work. Go through these steps before you begin any installation or maintenance work. 1. Clearly identify the work location and equipment. 2. Disconnect all possible voltage sources. Make sure that re-connection is not possible. Lock out and tag out. • Open the main disconnecting device of the drive. • Open the charging switch if present. • Open the disconnector of the supply transformer. (The main disconnecting device in the drive cabinet does not disconnect the voltage from the AC input power busbars of the drive cabinet.) • Close the grounding switch or switches ([Q9], option +F259) if present. Do not use excessive force as the switch has electromagnetic interlocking. • If the drive is equipped with a DC/DC converter unit (optional): Open the DC switch-disconnector ([Q11], option +F286) of the DC/DC converter. Open the disconnecting device of the energy storage connected to the DC/DC converter unit (outside the drive cabinet). • Open the auxiliary voltage switch-disconnector (if present), and all other possible disconnecting devices that isolate the drive from dangerous voltage sources. • In the liquid cooling unit (if present), open the motor protective circuit breaker(s) of the cooling pumps. • If you have a permanent magnet motor connected to the drive, disconnect the motor from the drive with a safety switch or by other means. • Disconnect any dangerous external voltages from the control circuits. • After you disconnect power from the drive, always wait 5 minutes to let the intermediate circuit capacitors discharge before you continue. 3. Protect any other energized parts in the work location against contact. 4. Take special precautions when close to bare conductors. Safety instructions 11

disassembly of shrouding or other cabinet structures, obey the local laws and regulations applicable to live working (including – but not limited to – electric shock and arc protection). • Use a multimeter with an impedance greater than 1 Mohm. • Make sure that the voltage between the drive input power terminals (L1, L2, L3) and the grounding (PE) busbar is close to 0 V. • Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W) and the grounding (PE) busbar is close to 0 V. • Make sure that the voltage between the drive DC busbars (+ and -) and the grounding (PE) busbar is close to 0 V. WARNING! The busbars inside the cabinet of liquid-cooled drives are partially coated. Measurements made through the coating are potentially unreliable, so only measure at uncoated portions. Note that the coating does not constitute a safe or touch-proof insulation. 6. If the drive is not equipped with a grounding switch, install temporary grounding as required by the local regulations. 7. Ask the person in control of the electrical installation work for a permit to work. 12 Safety instructions

function with PTC thermistor relays (+L513+Q971) Contents of this chapter This chapter describes the ATEX-certified motor thermal protection function (option +L513+Q971) and gives instructions on how to wire, install and start up the function. It also describes the PTC thermistor relays available for the option and gives fault tracing and maintenance instructions. The safety data is also given. Option description This protection function monitors the temperature of a motor with PTC resistor sensors (PTC thermistors) in a potentially explosive atmosphere. The function is activated when the PTC sensor resistance exceeds the overtemperature limit. It is possible to: • monitor the motor bearings or stator windings (+L513+Q971) • monitor the motor bearings and stator windings (+2L513+Q971 or +3L513+Q971). The safety function described in this manual activates the Safe torque off (STO) function of the drive when it detects motor overtemperature. The STO function of the ACS880 drives is certified (SIL 3 according to EN/IEC 61800-5-2 and IEC 61508). When activated, the STO function disables the control voltage of the power semiconductors of the drive output stage. This prevents the inverter from generating the torque required to rotate the motor. The motor coasts to a stop. For a detailed description of the STO function, see the hardware manual of your drive/inverter unit. ACS880-07/17/37 and ACS880-17LC/37LC drives with option +Q978: Also the main contactor/breaker is opened. 3 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971) 17

+F250/+F255), ACS880-17/37 drives (frames n×R8i + n×R8i) and ACS880-17LC/37LC drives (frames n×R8i + n×R8i): When the STO function is activated in the inverter unit, the main contactor/breaker is opened after user-defined delay (defined with parameter 94.11, the default value is 600 s). See hardware and firmware manuals for more information. Other safety functions in the drive can also use the STO function. Also, an FSO module can be included in the ATEX-certified motor thermal protection function. See the circuit diagrams delivered with the drive for the actual safety circuitry. The FSO safety functions module (FSO-12 or FSO-21) is an optional device used with the ACS880 drives to implement safety functions. When installed, it reserves the standard STO connection of the drive. The motor thermal protection function is implemented as follows: • without an FSO module, the opening contacts of the relay(s) open the STO circuit of the drive. • with an FSO module, the opening contacts of the relay(s) activate the STO or Safe stop 1 (SS1) function of the FSO module, and the FSO module opens the STO circuit of the drive. Select the stop category according to the system risk assessment. The protection function circuit is motor-specific. The function stops only the motor where overtemperature is detected. It is possible to get information on the status of the protection function through a normally-open contact of the relay. The information can be obtained separately from the bearing and stator sensors. The contact can be wired to a digital input on the drive control unit or to an external control system. See the wiring instructions. 18 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)

1. When the motor temperature rises to the thermistor wake-up level, the resistance of the thermistor increases sharply. 2. The PTC thermistor relay detects the change and indicates motor overtemperature through its output contacts. 3. The opening contacts of the PTC relay(s) open the STO circuit of the drive. This prevents the drive from generating the torque required to rotate the motor. 4. The drive generates an STO indication (parameter 31.22). 5. If the auxiliary contacts of the PTC relays are wired to a digital input of the drive (or inverter unit), the loss of the signal triggers a motor overtemperature indication in the drive. 6. After the motor temperature has decreased to normal, the user resets the PTC relay(s) using remote reset buttons (or the buttons on the PTC relays themselves). See the circuit diagrams of the delivery. 7. Optional: The user resets the drive faults either from the reset source defined by the user (parameter 31.11) or locally with the drive control panel: • the STO fault in the drive (if configured with drive parameter 31.22) • the motor overtemperature fault in the drive (if configured). Note: ABB recommends that you do not use the autoreset setting (that is, short-circuit the reset switch terminals of the PTC relay) with a safety device protecting an Ex motor. ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971) 19

1. When the motor temperature rises to the thermistor wake-up level, the resistance of the thermistor increases sharply. 2. The PTC thermistor relay detects the change and indicates motor overtemperature through its output contacts. 3. The opening contacts of the PTC relay(s) switch off the voltage to terminal X113:4 of the FSO module (this is configured as the input of the STO [or SS1] function in the FSO module). 4. The FSO module opens the STO circuit of the drive either immediately (STO function) or after a deceleration ramp (SS1 function). This prevents the drive from generating the torque required to rotate the motor. 5. The drive generates an STO indication (parameter 31.22). 6. The FSO module generates an STO indication (parameter FSOGEN.61). 7. If the auxiliary contacts of the PTC relay(s) are wired to a digital input, the loss of the signal triggers a motor overtemperature indication. 8. After the motor temperature has decreased to normal, the user resets the PTC relay(s) using remote reset buttons (or the buttons on the PTC relays themselves). See the circuit diagrams of the delivery. 9. Optional: The user resets the drive faults either from the reset source defined by the user (parameter 31.11) or locally with the drive control panel: • the STO fault in the drive (if configured with drive parameter 31.22) • the motor overtemperature fault in the drive (if configured). 10. Optional: The user resets the safety function in the FSO module with the reset button (if a reset circuit is wired and configured). 20 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)

reset switch terminals of the PTC relay) with a safety device protecting an Ex motor. ￭Implementation of the manual reset After the ATEX-certified motor thermal protection function activates, the motor must not restart before a manual reset command is given. The manual reset is set in the ATEX-certified PTC thermistor relay at the factory. This complies with the ATEX requirement on manual reset, which means that you do not have to configure any faults in the drive or FSO parameters. If you change the manual reset setting in the PTC thermistor relay, make sure that the user cannot restart the drive without a manual reset. You can configure the manual reset either in: • the drive with the motor overtemperature or STO indication parameters • the FSO module by connecting a reset circuit to the FSO module. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978 or +Q979 (Emergency stop): In these safety functions, a reset circuit is connected to the FSO module and the user must reset the safety function with the emergency stop reset button. The user must also reset the ATEX-certified motor thermal protection function with the emergency stop reset button. Do not change this setting. ￭Indications of the motor thermal protection function An indication of the safety function can come from several sources: • the motor overtemperature indication in the drive • the STO indication in the drive • the STO or SS1 indication in the FSO module. If you want to avoid parallel indications in overtemperature situations, you can set one or several of the indication parameters value to No indication (or None) or Event: • the motor overtemperature indication with drive parameters 31.01…31.02 or 35.11…35.12 • the STO indication in the drive with drive parameter 31.22 STO indication run/stop • the STO or SS1 indication in the FSO module with FSO parameter FSOGEN.61 STO indication ext request. If the PTC thermistor relay is not in the manual reset mode, make sure that at least one of these indications generates a fault. Commissioning the drive for a motor in a hazardous area Commission the drive according to the requirements and limitations set by the application, the motor manufacturer’s instructions, drive firmware manual, local laws and regulations and this manual. The certificate of the Ex motor typically requires that you set a minimum limit for the output switching frequency of the drive. Make sure that the Ex motor is operated above the minimum output switching frequency specified by the motor manufacturer.

The insulation of the temperature sensor in the Ex motor and the insulation of the protection relay form the insulation of the whole circuit. All Ex motors manufactured by ABB have basic insulation between the main circuit and the temperature sensor. The thermistor relays shown in this manual have basic insulation between the sensor circuit and relay output. This ensures that there is double insulation between the main circuit and the drive control unit. 24 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)

The sensor circuit in the Ex Zone must comply with the requirements for the applicable type of protection, such as: • Ex d (EN/IEC 60079-1) • Ex eb (EN/IEC 60079-7, Ex e in EN 60079-7:2007 and IEC 60079-7:2006) • Ex ec (EN/IEC 60079-7, Ex nA in EN/IEC 60079-15:2010). 2. Install the drive or inverter unit, including the components of the ATEX-certified motor thermal protection function, outside the potentially explosive atmosphere. 3. For the sensor connection, ABB recommends to use shielded twisted-pair cable. This type of cable decreases electromagnetic interference in the sensor circuit. 4. Route the sensor cables away from the motor cable. Power cables can cause electromagnetic interference in the sensor circuit. 5. Ground all sensor cable shields to a single grounding point outside the potentially explosive atmosphere. 360-degree grounding of the cable shields is recommended. Do not connect the cable shields to ground at the sensor end of the cable. ￭Wiring example 1. Connect the PTC sensor(s) of the motor to the PTC thermistor relay(s) [K74] (and [K75], [K76] if included) to terminal block [X506]. 2. Indication to the drive via DI6 (shown below): Connect a +24 V DC source via contacts 11 and 14 of the PTC thermistor relay(s) (pre-wired to terminal block [X506] at the factory) to digital input DI6 on the drive control unit. 3. Connect a reset button for the PTC relay(s) via terminal block [X506] (recommended). 4. With an FSO module (not shown in the figure): If necessary, connect a reset circuit to an input of the FSO module (for example, DI X113:2).

Start-up and acceptance test Use the Drive composer PC tool or a control panel to do the start-up and acceptance test. To set FSO module parameters, you must use the Drive composer pro PC tool. Action Initial status Make sure that the drive is ready for use, that is, you have done the tasks of the drive start-up procedure. See the drive hardware manual. WARNING! Obey the Safety instructions (page 9). If you ignore them, injury or death, or damage to the equipment can occur. Checks and settings with no voltage connected Stop the drive and do the steps in section Electrical safety precautions (page 11) before you start the work. Make sure that the classification of the motor thermal protection function corresponds to the Ex classi- fication of the environment and the Ex motor. The motor manufacturer selects the PTC sensors for the motor temperature measurement. Make sure that the temperature on-off resistances match those of the PTC thermistor relay. Also make sure that there is basic or reinforced insulation between the sensor and the motor main circuit. Make sure that the installation of PTC sensors complies with the requirements for the applicable type of protection. See section Wiring (page 24). Make sure that the wires are connected to the correct terminals and that the terminal connections are tightened. Settings with voltage connected If necessary, set the applicable parameters. See chapter Parameter settings (page 41). If necessary, configure the motor overtemperature and STO indication. See section Reset method and status indications (page 41). Acceptance test procedure To test short-circuit detection, short-circuit the sensor input with a 20 ohm resistance (you do not have to disconnect the sensor circuit). Expected outcome: Relay fault trip (the applicable LED lights). Drive STO is activated. Make sure that the correct indications are activated. To test wire break monitoring, disconnect the sensor circuit. Expected outcome: Relay fault trip (the applicable LED lights). Drive STO is activated. Make sure that the correct indications are activated. To test excess temperature detection, increase the resistance of the sensor circuit from 50 … 1500 ohm to 4 kohm. Expected outcome: Relay fault trip (the applicable LED lights). Drive STO is activated. Make sure that the correct indications are activated. With the relay(s) in tripped state, try to start the drive. The drive must not start before the PTC relay(s) and/or any drive (and FSO) faults are reset. Fill in and sign the acceptance test report which verifies that the safety function is safe and accepted to operation. 26 ATEX-certified motor thermal protection function with PTC thermistor relays (+L513+Q971)

function with Pt100 relays (+L514+Q971) Contents of this chapter This chapter describes the ATEX-certified motor thermal protection function (option +L514+Q971) and gives instructions on how to wire, install and start up the function. It also describes the Pt100 relays available for the option and gives fault tracing and maintenance instructions. The safety data is also given. Option description This protection function monitors the temperature of a motor with Pt100 sensors in a potentially explosive atmosphere. The function is activated when the motor temperature exceeds the set operating temperature limit of the Pt100 relay. It is possible to: • monitor the motor stator windings (+3L514+Q971) • monitor the motor bearings and stator windings (+5L514+Q971) • monitor the motor bearings and double-monitor the stator windings (+8L514+Q971). Other configurations are available as an order-based engineered option. The maximum number of Pt100 relays is 8. The safety function described in this manual activates the Safe torque off (STO) function of the drive when it detects motor overtemperature. The STO function of the ACS880 drives is certified (SIL 3 according to EN/IEC 61800-5-2 and IEC 61508). When activated, the STO function disables the control voltage of the power semiconductors of the drive output stage. This prevents the inverter from generating the torque required to rotate the motor. The motor coasts to a stop. For a detailed description of the STO function, see the hardware manual of your drive/inverter unit. 4 ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971) 29

contactor/breaker is opened. ACS880-07 drives (frames n×DxT + n×R8i) with a main contactor/breaker (option +F250/+F255), ACS880-17/37 drives (frames n×R8i + n×R8i) and ACS880-17LC/37LC drives (frames n×R8i + n×R8i): When the STO function is activated in the inverter unit, the main contactor/breaker is opened after user-defined delay (defined with parameter 94.11, the default value is 600 s). See hardware and firmware manuals for more information. Other safety functions in the drive can also use the STO function. Also, an FSO module can be included in the ATEX-certified motor thermal protection function. See the circuit diagrams delivered with the drive for the actual safety circuitry. The FSO safety functions module (FSO-12 or FSO-21) is an optional device used with the ACS880 drives to implement safety functions. When installed, it reserves the standard STO connection of the drive. The motor thermal protection function is implemented as follows: • without an FSO module, the opening contacts of the relay(s) open the STO circuit of the drive. • with an FSO module, the opening contacts of the relay(s) activate the STO or Safe stop 1 (SS1) function of the FSO module, and the FSO module opens the STO circuit of the drive. Select the stop category according to the system risk assessment. The protection function circuit is motor-specific. The function stops only the motor where overtemperature is detected. It is possible to get information on the status of the protection function through a normally-open contact of the relay. The information can be obtained separately from the bearing and stator sensors. The contact can be wired to a digital input on the drive control unit or to an external control system. See the wiring instructions. ￭Pt100 relays The Pt100 relays are configurable PLCs. In addition to the actuation of the motor thermal protection function, it is possible to get, for example, a 4 … 20 mA analog temperature signal from each Pt100 sensor. The used Pt100 relays are [Ex i] (intrinsically safe) approved associated apparatus (Ex i barrier). The installation and cabling of the protection circuit in the ACS880 cabinet is done as intrinsically safe according to EN/IEC 60079-14 ed. 5 clause 16. If Pt100 sensors in the Ex Zone are not protected by an Ex type of protection (eg, Ex eb, Ex ec or Ex d), the cabling from sensors to the terminal blocks in the drive must be done as intrinsically safe [Ex i] installation. To comply with the [Ex i] requirements, use shielded or shielded twisted pair cable. If Pt100 sensors in the Ex Zone are protected by an Ex type of protection (eg, Ex eb, Ex ec or Ex d), the intrinsically safe [Ex i] installation and cabling are not required. If the final installation does not need [Ex i] installation, the Ex i markings must be removed or covered from the cabinet. The drive delivery contains a notification label, stating: Note! This sensor circuit is not executed as intrinsically safe [Ex i] installation. If [Ex i] installation is not required, you must attach the label to the drive cabinet. 30 ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971)

on the insulation of the Pt100 relay, see the applicable relay data sheet. ￭Operation principle Without an FSO module 1. When the motor temperature rises, the sensor resistance increases linearly. 2. When the motor temperature exceeds the set operating temperature limit of the Pt100 relay, the relay indicates motor overtemperature through its output contacts. 3. The opening contacts of the extension relay(s) [-A81] ([-A82] and [-A83]) open the STO circuit of the drive. This prevents the drive from generating the torque required to rotate the motor. 4. The drive generates an STO indication (parameter 31.22). 5. If the extension relay(s) [-A81] ([-A82] and [-A83]) are wired to a digital input, the loss of the signal triggers a motor overtemperature fault in the drive. 6. After the motor temperature has decreased to normal, the Pt100 relays reset automatically. 7. The user must reset the drive faults either from the reset source defined by the user (parameter 31.11) or locally with the drive control panel: • the STO fault in the drive (if configured with drive parameter 31.22) • the motor overtemperature fault in the drive (if configured). ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971) 31

1. When the motor temperature rises, the sensor resistance increases linearly. 2. When the motor temperature exceeds the set operating temperature limit of the Pt100 relay, the relay indicates motor overtemperature through its output contacts. 3. The opening contacts of the extension relay(s) [-A81] ([-A82] and [-A83]) switch off the voltage to terminal X113:4 of the FSO module (this is configured as the input of the STO [or SS1] function in the FSO module). 4. The FSO module opens the STO circuit of the drive either immediately (STO function) or after a deceleration ramp (SS1 function). This prevents the drive from generating the torque required to rotate the motor. 5. The drive generates an STO indication (parameter 31.22). 6. The FSO module generates an STO indication (parameter FSOGEN.61). 7. If the extension relay(s) [-A81] ([-A82] and [-A83]) are wired to a digital input, the loss of the signal triggers a motor temperature fault in the drive. 8. After the motor temperature has decreased to normal, the Pt100 relays reset automatically. 32 ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971)

31.11) or locally with the drive control panel: • the STO fault in the drive (if configured with drive parameter 31.22) • the motor overtemperature fault in the drive (if configured). 10. Optional: The user must reset the safety function in the FSO module with the reset button (if a reset circuit is wired and configured). ￭Implementation of the manual reset After the ATEX-certified motor thermal protection function activates, the motor must not restart before a manual reset command is given. The Pt100 relay is reset automatically. To comply with the ATEX requirement on manual reset, make sure that the user cannot restart the drive without a manual reset. You must configure the manual reset either in: • the drive with the motor overtemperature or STO indication parameters • the FSO module by connecting a reset circuit to the FSO module. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978 or +Q979 (Emergency stop): In these safety functions, a reset circuit is connected to the FSO module and the user must reset the safety function with the emergency stop reset button. The user must also reset the ATEX-certified motor thermal protection function with the emergency stop reset button. Do not change this setting. ￭Indications of the motor thermal protection function An indication of the safety function can come from several sources: • the motor overtemperature indication in the drive • the STO indication in the drive • the STO or SS1 indication in the FSO module. If you want to avoid parallel indications in overtemperature situations, you can set one or several of the indication parameters value to No indication (or None) or Event: • the motor overtemperature indication with drive parameters 31.01…31.02 or 35.11…35.12 • the STO indication in the drive with drive parameter 31.22 STO indication run/stop • the STO or SS1 indication in the FSO module with FSO parameter FSOGEN.61 STO indication ext request. Make sure that at least one of these indications generates a fault to ensure that the required manual reset is implemented. Commissioning the drive for a motor in a hazardous area Commission the drive according to the requirements and limitations set by the application, the motor manufacturer’s instructions, drive firmware manual, local laws and regulations and this manual. The certificate of the Ex motor typically requires that you set a minimum limit for the output switching frequency of the drive. Make sure that the Ex motor is operated above the minimum output switching frequency specified by the motor manufacturer.

You need a dedicated programming tool for the relay. The programming tools are not included in the delivery. See the technical data for the ordering information. Wiring ￭Insulation of the sensor circuit When you connect the temperature sensor(s) of the Ex motor to the drive STO terminals through a relay, make sure that there is reinforced (double) insulation between the main circuit (motor) and the drive control unit as required by IEC 61800-5-1. The insulation of the temperature sensor in the Ex motor and the insulation of the protection relay form the insulation of the whole circuit. All Ex motors manufactured by ABB have basic insulation between the main circuit and the temperature sensor. The thermistor relays shown in this manual have basic insulation between the sensor circuit and relay output. This ensures that there is double insulation between the main circuit and the drive control unit. ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971) 35

1. Install only the sensor circuit into the potentially explosive atmosphere. The sensor circuit in the Ex Zone must comply with the requirements for the applicable type of protection, such as: • Ex d (EN/IEC 60079-1) • Ex eb (EN/IEC 60079-7, Ex e in EN 60079-7:2007 and IEC 60079-7:2006) • Ex ec (EN/IEC 60079-7, Ex nA in EN/IEC 60079-15:2010). 2. Install the drive or inverter unit, including the components of the ATEX-certified motor thermal protection function, outside the potentially explosive atmosphere. 3. For the sensor connection, ABB recommends to use shielded twisted-pair cable. This type of cable decreases electromagnetic interference in the sensor circuit. 4. Route the sensor cables away from the motor cable. Power cables can cause electromagnetic interference in the sensor circuit. 5. Ground all sensor cable shields to a single grounding point outside the potentially explosive atmosphere. 360-degree grounding of the cable shields is recommended. Do not connect the cable shields to ground at the sensor end of the cable. Note: For the motor thermal protection function with Pt100 relays, also the following types of protection for the sensor circuit are applicable: • Ex ib (EN/IEC 60079-11) • Ex ic (EN/IEC 60079-11). If the installation of the sensor circuit does not comply with an applicable type of protection, obey the installation and wiring requirements for intrinsically safe (Ex i) circuits, as given in EN/IEC 60079-14 ed. 5, clause 16. 36 ATEX-certified motor thermal protection function with Pt100 relays (+L514+Q971)

Stop the drive and do the steps in section Electrical safety precautions (page 11) before you start the work. Make sure that the classification of the motor thermal protection function corresponds to the Ex classi- fication of the environment and the Ex motor. The motor manufacturer selects the Pt100 sensors for the motor temperature measurement. Make sure that the temperature trip levels match those of the Pt100 relay and set the relay accordingly. Make sure that the installation of Pt100 sensors complies with the requirements for the applicable type of protection. See section Wiring (page 35). Make sure that the wires are connected to the correct terminals and that the terminal connections are tightened. Set the trip level of the Pt100 relay. For example, for temperature class T3 the values are: • 120 … 140 °C when only tripping is used • alarm 120 … 140 °C and trip 130 … 150 °C when both alarm and trip are used. Set the temperatures according to the temperature class of the motor. To modify the settings of the relay, you need a programming tool. See the technical data for ordering information. Make sure that the other settings of the relay are correct. Settings with voltage connected If necessary, set the applicable parameters. See chapter Parameter settings (page 41). If necessary, configure the motor overtemperature indication message. See section Motor overtemper- ature indication (page 42). Acceptance test procedure To do a test of the wire break monitoring, disconnect the sensor circuit. Expected outcome: Fault trip (the applicable LED lights). Drive STO is activated. Make sure that the correct indications are activated. With the relay(s) both in tripped and in reset state, try to start the drive. The drive must not start before the drive (and FSO) faults are reset. Fill in and sign the acceptance test report which verifies that the safety function is safe and accepted to operation. Maintenance After the operation of the safety circuit has been verified at start-up, the circuit requires a periodic proof test at least every two years. If you change any wirings or components related to the motor thermal protection function after the start-up, repeat the procedure given in section Start-up and acceptance test (page 37). Fault tracing For the warning and fault messages generated by the drive, see the drive firmware manual. For the fault indication LEDs of the relays, see section Pt100 relays (page 34).

This chapter lists the parameters that you have to set for the ATEX-certified motor thermal protection functions in this manual. WARNING! If there is missing or inaccurate information, do not operate the motor before you have made sure that the parameter settings are correct. Drive / inverter ￭Switching frequency limitation The certificate of the Ex motor typically requires that you set a minimum limit for the switching frequency of the drive. For ABB Ex motors, use parameter 95.15 to set the required minimum switching frequency. For more information, see the drive firmware manual. For Ex motors supplied by other motor manufacturers, contact the motor manufacturer for the correct value and your local ABB representative for instructions on how to make the parameter setting in the drive. ￭Reset method and status indications To configure a manual reset for the temperature protection function in the drive, you can set either the STO indication (parameter 31.22 STO indication run/stop) or the motor temperature indication so that it generates a fault. 31.22 STO indication run/stop Set this parameter to value Fault/Fault or Fault/Warning. 5 Parameter settings 41

• Fault/Warning: This generates a fault in the drive/inverter unit when the drive is running and warning when the drive is stopped. When the drive/inverter unit generates a fault indication because of STO activation, you must reset the drive/inverter unit before you can restart the drive. Note: You can also configure the FSO module so that it sends a fault to the drive each time it activates the drive STO function. See parameter FSOGEN.61. The default values set for the options at the factory: • option +L513+Q971 (PTC relays, with or without an FSO module): Warning/Warning • option +L514+Q971 (Pt100 relays, with or without an FSO module): Fault/Fault. Motor overtemperature indication There are two ways to configure the motor overtemperature indication. Example 1 The ACS880 primary control program has two separate temperature monitoring functions. In this example, one of these functions (External event 1) is configured to monitor digital input DI6. When off (0), the function triggers the user-selected indication and shows the user-defined message. To configure the motor overtemperature indication in the drive: 1. Select the digital input which shows the status of the external event: set parameter 31.01 External event 1 source to DI6. You can also use another digital input. 2. Select the type of the External event 1: set parameter 31.02 External event 1 type to Fault, Warning or Warning/Fault. If you set this parameter to Fault, the drive trips due to overtemperature and you must reset the drive with a manual reset command before you can restart the drive. 3. If necessary, edit the indication message. You can use the control panel or Drive composer PC tool to edit messages. Example 2 In this example, the motor temperature is read from digital input DI6. 1. Select PTC DI6 as the source of the temperature with parameter 35.11 Temperature 1 source. Use the same setting also with Pt100 sensors. 2. By default, an excessive temperature will generate a warning. If you want a fault instead, set parameter 35.12 Temperature 1 fault limit to 4000 ohm. 3. If necessary, edit the indication message. You can use the control panel or Drive composer PC tool to edit messages. For more information, see ACS880 primary control program firmware manual (3AUA0000085967 [English]). 31.11 Fault reset selection Select the correct source of an external fault reset signal with parameter 31.11 Fault reset selection. ￭Other recommended settings ABB recommends that you also set these parameters to improve the safety of the application: • minimum and maximum speeds (parameter group 30) • maximum current, power and torque (group 30) • acceleration and deceleration times 42 Parameter settings

FSO module If you use an FSO module (option +Q972 or +Q973) in the safety system configuration, set the parameters according to the system requirements. Example values are shown in this section. You need the Drive composer pro PC tool to set the FSO module parameters. You also need a password to be able to download the configuration to the FSO module from Drive composer pro. For the default password of the FSO module, see the applicable FSO module user’s manual. For more information on the Drive composer pro PC tool, see Drive composer start-up and maintenance PC tool user's manual (3AUA0000094606 [English]). Follow the configuration steps described in the applicable FSO module user’s manual, chapter Configuration. There are parameters that you must always set when you use the FSO module, and parameters that are related only to some safety functions. These tables list the parameters that are relevant to the options +L513+Q971+Q973/Q972 and +L514+Q971+Q973/Q972. The example values are applicable only to these options. You can use the FSO-21 module (+Q972) also with a safety pulse encoder and the FSE-31 pulse encoder interface module (+L521). If you do, set the parameters listed in section FSE module and safety pulse encoder parameters (page 50). You can configure the FSO module so that it opens the drive or inverter STO circuit immediately (STO function in the FSO module, stop category 0) or after a deceleration ramp (SS1 function in the FSO module, stop category 1). For the options described in this manual, ABB has configured the FSO module so that it activates the STO function (stop category 0). Select the stop category according to the system risk assessment. Do not configure the STO function and the SS1 function to the same input at the same time. Note: Setting parameters related to STO and SS1 can also have an effect on other safety functions. You must take all safety functions into consideration when you configure the FSO module. See the applicable FSO module user’s manual and safety option user's manual. Note: The factory reset of the FSO module clears the configuration and sets the parameters to the factory default values. These values are not the same as the pre-set values in an FSO module that was ordered as an option (with a plus code). You cannot restart the drive with the factory default values. If you do a factory reset of the FSO module, you must reconfigure the FSO module and set the applicable parameters. See the applicable FSO module user's manual. Parameter settings 43

Manual: The FSO module reads the external acknow- ledgement signal through the digital input defined by parameter FSOGEN.42. Make sure that the value is Automatic. Sets the digital input for the acknowledgement signal when parameter STO.02 has value Manual. None Acknowledgement button input FSOGEN.42 None: In the safety functions described in this manual, parameter STO.02 has value Automatic and this para- meter has value None (no acknowledgement signal connected). In the safety functions described in this manual, you can use this parameter to implement manual reset in the FSO module. Set the digital input which the reset circuit is connected to with this parameter. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978 or +Q979: The value of this parameter is DI X113:2. A reset circuit is connected to the FSO module and the user must reset the safety function with the emergency stop reset button also when motor overtemperature is reached. Do not change this setting. Sets the general zero speed limit for safety functions when no safety encoder is in use. 90.0 rpm Zero speed without encoder FSOGEN.51 STO function: The value has no effect. SS1 function: The FSO module activates the drive STO function when the drive has decelerated the motor speed below this value. Adjust the default value accord- ing to application requirements.

SS1 function: The FSO module activates the drive STO function when the drive has decelerated the motor speed to less than this value. Adjust the default value according to application requirements. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978: Also the main contactor/breaker is opened. Note: This parameter is used only with FSO-21 and when a safety encoder is used in the application. Sets the type of the event that the FSO module gener- ates and sends to the drive after external requests that end to a successful activation of the drive STO function (STO, SSE or SS1). Warning STO indication ext request FSOGEN.61 None, Warning, Event: You do not have to reset the drive/inverter unit. Fault: You have to reset the drive/inverter unit. In the safety functions described in this manual, you can use this indication as the motor overtemperature indication message and to implement a manual reset. Adjust the default value when necessary. Sets the type of the event that the FSO module gener- ates and sends to the drive for limit hits during ramp and time monitoring of safety ramps SAR0 and SAR1. Fault STO indication safety limit FSOGEN.62 STO function: The value has no effect. SS1 function: When the motor speed does not follow the stop ramp or the time limit is exceeded, the FSO module activates the STO function and generates this user-defined indication. Adjust the default setting if ne- cessary. If you select Fault, you must reset the drive before you can restart it. Parameter settings 45

These parameters are related to the STO function of the FSO module. With stop category 0, the FSO module activates the STO function in overtemperature situations. Also, the FSO module can activate the STO function in fault situations. Description Example value Name Index Sets the acknowledgement method used in the STO, SSE and SS1 functions. Automatic STO acknowledge- ment STO.02 Automatic: The FSO module resets the STO function automatically after the STO request is removed. Manual: The FSO module reads the external acknow- ledgement signal through the digital input defined by parameter FSOGEN.42. In the safety functions de- scribed in this manual, you can use this setting to im- plement a manual reset for the motor temperature protection function in the FSO module. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978 or +Q979: The FSO module is con- figured so that after the safety function activation, the user must reset the FSO manually with the emergency stop reset button (this parameter is set to Manual). In this case, the user must reset the FSO module with the emergency stop reset button also when motor overtem- perature is reached. Do not change this setting. Sets the digital input that is connected to the primary input of the STO function. None STO input A STO.11 In the safety functions described in this manual, this parameter has value None. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978 or +Q979: ABB has connected the emergency stop button to this digital input at the factory. Make sure that the setting corresponds to the circuit diagrams of the delivery.

STO: DI X113:4 SS1: None STO input B STO.12 For the safety functions described in this manual, ABB has configured the contacts of the PTC/Pt100 relay to this digital input at the factory. Make sure that the set- ting corresponds to the circuit diagrams of the delivery. If you set this parameter to DI X113:4, set parameter SS1.12 to None. Sets the time after which the drive can restart when the FSO module has activated the STO function and opened the drive STO circuit. With this parameter, you can let the drive restart before the motor has stopped (fly-start). This parameter is applicable only if the STO function is requested from STO input A (STO.11) or STO input B (STO.12). 2000 ms Restart delay after STO STO.13 STO function: Adjust the value when necessary. If you do not want to use the fly-start feature, set this paramet- er to the same value as parameter STO.14. SS1 function: This value has no effect. 46 Parameter settings

standstill from maximum process speed. If this time is not known, it can be measured with Drive composer pro PC tool when an encoder is used for motor control (otherwise you have to make sure that the motor shaft has stopped rotating by other means, eg, visually). 2000 ms Time to zero speed with STO and modoff STO.14 Acknowledgement is allowed after coast stop in the STO, SSE and SS1 functions (when SBC is not used). If the drive STO is activated or modulation stopped while a monitoring safety function is indicating “unsafe”, after this time acknowledgement is allowed. For ex- ample, if the drive modulation is lost during SLS decel- eration ramp, SLS OK will be indicated after this time has elapsed. STO function: This parameter sets the time after which the STO function is completed and the STO completed indication goes on. Parameter STO.13 defines the time after which the acknowledgement is allowed. Adjust the value according to application requirements. SS1 function: This parameter is used only when the motor speed does not follow the ramp settings or the time monitoring limit is exceeded and the FSO module activates the STO function. Adjust the value according to application requirements. When an encoder is used: This parameter is relevant only if there is an encoder failure and the FSO module activates the STO function. SBC usage Sets how the mechanical brake is used together with the STO function. None STO SBC usage SBC.11 In the safety functions described in this manual, this feature is not used and this parameter has value None. ACS880-07/17/37 and ACS880-17LC/37LC drives with the option +Q978: The SBC function is used in the emergency stop implementation to control the auxiliary safety relay(s) which is connected to the main contact- or/breaker. Make sure that the value is Delayed brake. ￭Parameters for the SSE function These parameters are related to the Safe stop emergency (SSE) function of the FSO module. The safety functions described in this manual do not use this function, but the FSO module can activate the SSE function in internal fault situations. Description Example value Name Index Sets the type of the SSE function. Immediate STO SSE function SSE.13 Immediate STO: The FSO module activates the drive STO function immediately after the SSE request (stop category 0). Emergency ramp: The FSO module first ramps down the motor speed and when the speed is below the zero speed limit (parameter FSOGEN.51 or FSOGEN.52) it activates the STO function (stop category 1). SAR0 parameters define the deceleration ramp (for more information, see the FSO module user’s manual). For the safety functions described in this manual, ABB has set this parameter to value Immediate STO at the factory. Adjust the default value when necessary. Parameter settings 47

activates the brake (SBC) while ramping. 0.0 rpm SSE/SS1 SBC speed SBC.15 0.0 rpm: The feature is not in use. In the safety functions described in this manual, this feature is not used. Make sure that the value is 0.0 rpm. ￭Parameters for the SS1 function Set these parameters only if you want that the FSO module activates the SS1 function in overtemperature situations (stop category 1). Description Example value Name Index Activates or deactivates the SS1 function and shows the version of the SS1 function. Version 1 SS1 activity and ver- sion SS1.01 Version 1: Activates version 1 of the SS1 function. For more information, see the FSO module user’s manual. Sets the digital input that is connected to the primary input of the SS1 function. None SS1 input A SS1.11 Sets the digital input that is connected to the secondary input of the SS1 function. STO: None SS1: DI X113:4 SS1 input B SS1.12 If you set this parameter to DI X113:4, set parameter STO.12 to None. Sets the method used for the SS1 monitoring. Adjust the default value when necessary. SS1-r SS1 type SS1.13 Time monitoring (SS1-t): The FSO module monitors that a user-defined deceleration time limit is not ex- ceeded. (See parameter SS1.14.) Ramp monitoring (SS1-r): The FSO module monitors that the motor decelerates along a user-defined stop ramp. (See SAR1 ramp parameters 200.112, SARx.21, SARx.22 and SARx.02.) Sets the monitoring delay after which the FSO module activates the drive STO and SBC at the latest, if the motor speed has not gone below the zero speed limit (parameter FSOGEN.51 or FSOGEN.52) yet. 20000 ms SS1-t delay for STO SS1.14 Time monitoring: This value sets the security delay that the FSO module monitors. Adjust the default value when necessary. Ramp monitoring: This value has no effect in the oper- ation. SAR1 ramp settings Sets the target time for the stop ramp SAR1 that is used in the SS1 and function. Adjust the default value when necessary. 2000 ms SAR1 ramp time to zero 200.112 The target time is the time in which the drive deceler- ates the motor from the speed defined by parameter 200.202 to zero. Note: With value 0 ms, the drive uses the emergency stop ramp set by drive parameter 23.23 (see section SS1 ramp parameters in the drive/inverter unit (page 50)). Also in this case, the FSO module only monitors the actual ramp (ramp monitoring or time monitoring). 48 Parameter settings

reference point in ramp parameter calculations (see SAR1 ramp parameters 200.112, SARx.21, SARx.22 and SARx.02.). Adjust the default value when neces- sary. 1500 rpm SAR speed scaling 200.202 Sets the initial allowed range for the SAR0/SAR1 ramp. This parameter moves the location of the maximum monitoring ramp forward on the time axis, when monit- oring is started. The slope of the ramp stays the same as defined with parameters 200.202 and SARx.22. For more information, see the FSO module user’s manual. 100 ms SAR initial allowed range SARx.02 Time monitoring: This value has no effect in the opera- tion. Ramp monitoring: Adjust the default value when neces- sary. Sets the minimum ramp time for the SAR1 ramp monit- oring. 1000 ms SAR1 min ramp time to zero SARx.21 Time monitoring: This value has no effect in the opera- tion. Ramp monitoring: Sets the minimum stop ramp time for the emergency stop. Adjust the default value when necessary. Note: With value 0 ms, the minimum ramp is not mon- itored. Sets the maximum ramp time for the SAR1 ramp monitoring. 3000 ms SAR1 max ramp time to zero SARx.22 Time monitoring: This value has no effect in the opera- tion. Ramp monitoring: Sets the maximum stop ramp time for the emergency stop. Adjust the default value when necessary. SBC usage Sets the absolute speed below which the FSO module activates the brake (SBC) while ramping. 0.0 rpm SSE/SS1 SBC speed SBC.15 0.0 rpm: The feature is not in use. In the safety functions described in this manual, this feature is not used. Make sure that the value is 0.0 rpm. In addition to the parameters related to the SS1 function, set these parameters. Value with the SS1 function Pre-set value (STO function) Name Index None DI X113:4 STO input B STO.12 If you do not use a safety encoder, adjust the default value to meet the motor in use. 90.0 rpm Zero speed without encoder FSOGEN.51 If you use a safety encoder, adjust the default value to meet the motor in use. 0.0 rpm Zero speed with encoder FSOGEN.52 Adjust the default value when necessary. Fault STO indication safety limit FSOGEN.62 Parameter settings 49

Set these parameters only for the SS1 function. If FSO parameter 200.112 is set to 0 ms, drive parameters define the stop ramp that is used in the SS1 function: • 21.04 Emergency stop mode is set to value Eme ramp stop (Off3) • 23.23 Emergency stop time is set to a suitable value. Also in this case, the FSO module monitors the actual stop ramp (ramp monitoring or time monitoring). For more information, see the drive firmware manual and FSO module user's manual. ￭FSE module and safety pulse encoder parameters Set these parameters only when you use a safety pulse encoder and the FSE-31 pulse encoder interface module with the FSO-21 module. Description Example value Name Index Activates the FSE-31 encoder interface and shows the version of the encoder parameter groups (91 and 92). Version 1 FSE 3X act and par version 200.231 Shows the number of safety pulse encoders connected to the FSE module. Single encoder CH1 Number of encoders 200.232 Activates the safety pulse encoder and shows the ver- sion parameter group S_ENCGEN. Version 1 Safe pulse encoder version S_ENCGEN.01 Sets the action taken when there is a problem with the FSE module. STO FSE diagnostic fail- ure reaction S_ENCGEN.11 STO: The FSO module goes into the Fail-safe mode and activates the drive STO function. Note: This parameter is relevant only when there are no active safety functions. Sets the encoder speed cross comparison tolerance. This defines how much the axle speed of the motor can change within 1 ms. 1.0 rpm Enc speed cross comp tolerance S_ENCGEN.14 Adjust the default value to meet the motor in use. This parameter is used for the encoder diagnostic. It defines the maximum difference between the speed information from channel A and B of the encoder. If the difference of these two values is more than defined by this parameter, FSO will safely stop the system (STO). The suitable value depends on the configuration (motor and load). Typically this value is between 2 … 10 rpm. A value that is too small will cause an encoder fault (A7D8). A value that is too big will prevent the encoder diagnostic related to this parameter. Sets the rotation direction for the safety pulse encoder. 1 Gear numerator en- coder 1 S_ENCGEN.41 With this parameter, you can change the rotation direc- tion of the motor. Adjust the default value if necessary. Sets the type of the safety pulse encoder interface module 1. FSE-31 Module 1 type 91.11 Sets the slot in which the safety pulse encoder interface module 1 is located. 2 Module 1 location 91.12 Activates or deactivates the communication with the safety pulse encoder interface module 1 and sets the type for the safety pulse encoder. HTL1 Encoder 1 type 92.01 50 Parameter settings

the safety pulse encoder 1 is connected to. Module 1 Encoder 1 source 92.02 Sets the number of HTL pulses per revolution for safety pulse encoder 1. 2048 Pulses/revolution 92.10 Adjust the default value to meet the safety pulse en- coder in use. Make sure that the value is according to the encoder nameplate. Sets the maximum pulse frequency range of encoder 1. Adjust the default value to meet the motor and safety pulse encoder in use. You can use this formula to define the value: r_max · ppr_enc + 10%, where 300 kHz Accepted pulse freq of encoder 1 92.17 • r_max: the maximum motor speed (rpm) used in the application (or the motor nominal speed) • ppr_enc: pulses/revolution of the safety pulse en- coder (parameter 92.10). ￭Notes ACS880-07/17/37 and ACS880-17LC/37LC drives with option +Q978: In motor overtemperature situations, the FSO module also opens the main contactor/circuit breaker. ACS880-07/17/37 and ACS880-17LC/37LC drives with option +Q978 or +Q979: The FSO module is configured so that after the safety function activation, the user must reset the FSO module manually with the emergency stop reset button. The user must also reset the FSO module with the emergency stop reset button after motor overtemperature situations. The indication lamp on the reset button is on. Do not change this setting. Mechanical brake control If you use a mechanical brake with the motor thermal protection circuit, pay special attention to the control of the mechanical brake. If the motor deceleration by the mechanical brake causes extra heat generation in the Ex zone, make sure that the use of the brake does not increase the temperature too much. In this case, make sure that the mechanical brake is activated only at zero speed (see parameters SBC.11, SBC.15 and FSOGEN.51 or FSOGEN.52). In some cases you cannot use the brake for the motor deceleration when the motor thermal protection circuit has tripped and the motor temperature is too high. For more information, see the drive firmware manual (or the FSO module user’s manual if you use the Safe brake control (SBC) function of the FSO module). Parameter settings 51

General rules, notes and definitions ￭Validation of the safety functions You must do an acceptance test (validation) to validate the correct operation of safety functions. Competence The acceptance test of the safety function must be carried out by a competent person with expertise and knowledge of the safety function as well as functional safety, as required by IEC 61508-1 clause 6, and ATEX/Ex regulations. The test procedures and report must be documented and signed by this person. Validation procedure You must do the acceptance test using the checklist given in section Start-up and acceptance test: • at initial start-up of the safety function • after any changes related to the safety function (wiring, components, safety-function-related parameter settings, etc.) • after any maintenance work related to the safety function. The acceptance test must include at least the following steps: • you must have an acceptance test plan • you must test all commissioned functions for proper operation, from each operation location 62 Technical data

• you must sign and store the acceptance test report for further reference. Acceptance test reports You must store the signed acceptance test reports in the logbook of the machine and in the explosion protection document under the scope of the ATEX User Directive 1999/92/EC. The report must include, as required by the referred standards: • a description of the safety application (including a figure) • a description and revisions of safety components that are used in the safety application • a list of all safety functions that are used in the safety application • a list of all safety-related parameters and their values • documentation of start-up activities, references to failure reports and resolution of failures • the test results for each safety function, checksums, date of the tests, and confirmation by the test personnel. You must store any new acceptance test reports performed due to changes or maintenance in the logbook of the machine and in the explosion protection document under the scope of the ATEX User Directive 1999/92/EC. ￭Ambient conditions For the environmental limits for the safety functions and the drive, refer to the hardware manual. ￭Reporting problems and failures related to safety functions Contact ABB.

Contents of this chapter This chapter contains circuit diagram examples. The purpose of the example circuit diagrams is to help in understanding the operation of the ATEX-certified motor thermal protection functions. The diagrams do not cover all possible details and variants of the drives. The component designations do not necessarily match each drive. For the actual configuration, see the circuit diagrams delivered with the drive. WARNING! Do not connect, test or measure a drive based on the diagrams of this manual. Each delivery is unique. Before you start the work on the electric circuits of a drive, always refer to the delivery-specific circuit diagrams. For the sensor connection, ABB recommends to use shielded twisted-pair cable. This type of cable decreases electromagnetic interference in the sensor circuit. 70 Circuit diagrams
