for controlling instrument status and pro- gramming. The device can also be con- nected to a remote display. At start-up the instrument performs a Lamp Test; the display and LEDs flash for a few seconds to check that they are work- ing correctly. The instrument has two main menus: the Machine Status menu and the Programming menu. ACCESSING AND USING MENUS The resources are arranged in a menu that can be accessed by pressing and quickly releasing the “set” button (Machine Status menu) or holding down the “set” button for more than 5 seconds (Programming menu). To access the contents of each folder indicated by the relevant label, just press the “set” button once. You can now scroll through the contents of each folder, modify it or use its func- tions. If you do not use the keyboard for over 15 seconds (time-out) or if you press the “fnc” button once, the last value shown on the display is confirmed and you are taken back to the previous screen mask. REMOTE DISPLAY This has a display with 3 digits + sign that displays the parameter programming and alarm display values on the controller it is connected to during probe reading. MACHINE STATUS MENU (See Machine Status Menu Diagram) To access the Machine Status menu, press the “set” button and quickly release it. If no alarms are present, the label “SEt” appears. By using the “UP” and “DOWN” buttons you can scroll through the other folders in the menu: -AL: alarm folder (if alarms present, except for faulty probes/probe errors; -SEt: Set point setting folder. -rtc: Real Time Clock folder -Pb1: probe 1 value folder; -Pb2: probe 2 value folder; -Pb3: probe 3 value folder (if present); Set setting Access the “Machine Status” menu, press the “set” button and quickly release it. The “Set” folder label appears. To display the Set point value, press the “set” button again. The Set point value appears on the display. To change the Set point value, use the “UP” and “DOWN” buttons within 15 sec- onds. If the parameter is LOC = y the Set point cannot be changed. Alarm on If an alarm condition exists when the Machine Status menu is accessed the “AL” folder label appears (see section on “Diagnostics”). Real Time Clock By pressing the “set” button when the “rtc” label appears, the label d00 (days) is Position Associated function Status Set point/Reduced set point ON for parameter programming level 2 blinking when reduced set point is entered (set point ON for setting set point) Compressor or relay 1 ON for compressor on; blinking for protection delay or enabling blocked Defrosting ON when defrosting in progress; blinking when activated manually or by digital input Alarm ON for active alarm; blinking for silenced alarm Fans ON when fan is on aux ON when auxiliary output is operating ID 985 /E LX electronic controllers for “ventilated” refrigeration units with remote display fnc set ID985/E LX aux set fnc cod. 9IS43080 rel. 3/05 GB aux UP button Scrolls through the menu items Increases values Activates manual defrosting (see H31 parameter) DOWN button Scrolls through the menu items Decreases the values Parameter programmable (see H32 parameter) fnc button ESC function (quit) Parameter programmable (see H33 parameter Set button Accesses Set point and rtc folder Accesses the Menus Confirms the commands Displays the alarms (if active) Stores hours/min LEDs BUTTONS AND DISPLAY

tons to set days. If you do not use the but- tons for over 2 seconds or if you press “set” you switch to the hours (h00) and minutes (‘00) folders: use the “UP” and “DOWN” buttons to set the hours and minutes respectively. If you do not use the keyboard for over 15 seconds (time-out) or if you press the “fnc” button once, the last value shown on the display is con- firmed and you are taken back to the pre- vious screen mask. NOTE: Always use the “set” button to confirm the hours/minutes/days setting. NOTE2: We recommend considering the first day d00 as SUNDAY. Displaying probes If you press the “set” button when the corresponding label appears, the value of the probe associated with it is displayed. PROGRAMMING MENU (See Programming Menu Diagram) 1) Displaying level 1 parameters To access the Programming menu, hold the “set” button for more than 5 seconds. If specified, the level 1 access PASSWORD will be requested (see parameter “PA1”) and (if the password is correct) the label of the first folder will appear. If the pass- word is incorrect, the display will show the PA1 label again. When the instrument is on stand-by, para- meter programming can be accessed with the display both on and off. Use the “UP” and “DOWN” buttons to scroll through the other folders; the fold- ers will only display level 1 parameters. NOTE: at this point level 2 parameters are NOT visible even if NOT password- protected. 2) Displaying level 2 parameters Go to the “CnF” folder in the Programming Menu and scroll down the parameters until you reach the PA2 label. By pressing and releasing the “set” button you will enter the level 2 parameters and the label of the first folder in the pro- gramming menu will appear. Level 2 parameters can be protected by a second password (see “PA2” parameter in “diS” folder, not to be confused with PA2 label in the “CnF” folder). If specified, level 2 parameters are hidden from the user; when accessing the “CnF” folder the level 2 access PASSWORD will be requested and (if the correct password is entered) the label of the first folder in the program- ming menu will appear. NOTE: At this point the folders will only display all the level 2 parameters. Therefore level 1 parameters will only be visible if you quit the Programming Menu and repeat procedure 1). To enter the folder, press “set”. The label of the first visible parameter will appear. To scroll through the other parameters, use the “UP” and “DOWN” buttons. To change the parameter, press and release “set”, then set the desired value using the “UP” and “DOWN” buttons and confirm with the “set” button. Move on to the next parameter. NOTE: We strongly recommend that you switch the instrument off and on again each time parameter configuration is changed in order to prevent malfunction- ing of the configuration and/or ongoing timings. PASSWORD Passwords “PA1” and “PA2” allow level 1 and level 2 parameters to be accessed. There are no passwords in the standard configuration. To enable them (value 0) and assign them the desired value, access the Programming menu in the “diS” folder. If passwords are enabled, they will be requested: - PA1 when entering the Programming menu (see the “Programming Menu“ sec- tion); - PA2 in the “Cnf” folder containing the level 1 parameters. FnC FUNCTION FOLDER The FnC folder (last folder visible from the Programming Menu, level 1) con- tains the following functions. They are activated using the “set” but- ton If the unit is switched off, the function labels go back to their default status. ACTIVATING MANUAL DEFROST CYCLE To activate the defrost cycle manually, press the “UP” button (if configured =1) for 5 seconds. If the right defrosting con- ditions are not present (the temperature of the evaporator probe is higher than the end of defrost temperature, for example) or parameter OdO 0, the display will flash three (3) times to indicate that the opera- tion will not be performed. USING THE COPY CARD The Copy Card is an accessory connected to the TTL serial port and used for quick programming of the unit parameters (upload and download parameter map to one or more units of the same type). Operations are described below: Fr-Format (level 2 parameter) This command can be used to format the copy card necessary when used for the first time or when used with models that are not compatible. Warning: when the copy card has been programmed all the data entered is cancelled when the “Fr” parameter is used. This operation cannot be undone. UL-Upload This operation uploads the programming parameters from the instrument. dL-Download This operation downloads the program- ming parameters to the instrument. NOTE: • UPLOAD: instrument —> Copy Card • DOWNLOAD: Copy Card —> instr. The operations are performed by accessing the folder identified by the “FPr” label and selecting the “UL”, “dL” or “Fr” commands. The operation is confirmed by pressing the “set” button. If the operation is successful, a “y” is dis- played whereas if it is unsuccessful an “n” will be displayed. Download “from reset” Connect the copy card with the instrument OFF. When the instrument is switched on the programming parameters will be down- loaded; when the lamp test has been com- pleted, the following appear on the display for about 5 seconds: • label dLY if copy operation is successful • label DLn if operation fails NOTE: • after downloading the instrument will work with the parameter map settings that have just been downloaded. DISTANCE-MANAGED SYSTEMS The Televis remote control systems can be connected using the TTL serial port (the TTL- RS 485 BUS ADAPTER 100 interface module must be used). To configure the instrument to do this, you need to access the folder with the “Add” label and use the “dEA” and “FAA” parameters. KEYBOARD LOCKED Keyboard operating can be locked by pro- gramming the “Loc” parameter (see folder with “diS” table). If the keyboard is locked you can access the Programming Menu by pressing the “set” button. The Set point can also be displayed. ADVANCED FUNCTIONS DOOR SWITCH INPUT This is a clean contact digital input with programmable polarity. The door switch input functions are con- trolled by the values of the following para- meters: ID 985/E LX 2/13 Function Reduced set point Aux Pressure switch alarm reset **default Function label NOT ACTIVE SP** AoF rPA Label Function ACTIVE OSP Aon rPA

is not 0), the compressor and/or fan out- puts can be activated when the time set in parameters dCO and dFO expires. Parameter H11 is used to configure the digital input with values between -9 and +9. Positive and negative values are used to select the polarity assigned to the input and: NOTE: the sign “-” indicates that the input is activated when the contact is closed The ‘+’ sign indicates that the input is activated when the contact is open DEVICE STAND-BY CONTROLLER This controls the operating mode of the device when it is on stand by according to the following parameters: The Stand-by controller can be digital input or button enabled if suitably configured. The status of the instrument when on stand-by is determined by the value of parameter H08. Three possible operating modes are defined: EXAMPLE 1: the display is off and the con- trollers active, the instrument signals any alarms by reactivating the display - OFF DIS- PLAY EXAMPLE 2: the display is off and all the controllers, including the alarms, are also disabled - STAND-BY EXAMPLE 3: the display shows the “OFF” label and all the controllers, including the alarms, are also disabled- STAND-BY LINK The Link function is used to connect up to 8 instruments (1 Master device and 7 slave devices). The distance between one device and another must be 7 metres maximum whereas the maximum distance between the first and last instrument in the network must be approximately 50m. NOTE: the serial link between the devices is powered. Master Instrument that controls the networks and sends commands to the Slaves. The Master is selected using parameter L00 (the value 0 defines the Master) Slave Instrument(s) with own controllers that also perform(s) commands issued by the Master (with parameters L03..L06). Echo This only displays the values of the instru- ment that it is associated with (it does not therefore have its own I/O resources but only serves as a repeater). NOTE: only one Echo can be connected to anyone instrument. Defrosting The Link network controls defrosting. The Master sends the defrost command which can be performed synchronously (at the same time) or sequentially (one defrost after another) without affecting the normal protections or delays for each instrument (see parameter L03). Other Functions The Master can also activate the functions associated with buttons or the Digital Input for all the Slaves: switching lights on/off, alarm silencing, auxiliary set point, auxiliary relay, stand-by (on/off) and functions relat- ed to Night & Day controller (see parame- ter L05). The Master can also synchronize the Slave (or Echo device) displays with the Master device display (see parameter L04). NOTE: synchronized defrosting refers to actual defrosting and not to dripping and subsequent defrosting. The defrost LED on the Slave units blinks when synchronized defrosting has terminated and the Slaves are awaiting for the thermostat control to be enabled by the Master. The functions are associated with the instruments by correctly setting the para- meters (see the parameter table for the “Lin” label folder) DEFROST CONTROL The instrument can be used to select dif- ferent types of defrosting with the para- meter dty, defrost type. (defrost execution mode). The dty parameter can have these values: 0 = electrical defrosting; the compressor is turned off. 1 = cycle reversing defrosting (hot gas); the compressor continues operating. 2 = Free mode defrosting (compressor dis abled). Configuration of 3rd probe as 2nd evap- orator probe The 3a probe can be used to control the defrosting of a second evaporator by con- figuring a relay output as a 2nd evaporator defrost relay (see par. H21…H26). To implement this function: a) configure the 3rd probe in 2nd evapora- tor defrost control mode (par. H43=2EP). b) configure a relay output as 2nd evapo- rator defrost relay (configuration parame- ters H21…H26). c) define the defrost mode by setting parameter H45. Start of defrosting If two evaporators are used, defrosting starts in three different ways that are determined by parameter H45. • H45=0: Defrosting is enabled by con- trolling the temperature of the 1st evapo- rator so it is lower than parameter dSt, •H45=1: Defrosting is enabled by control- ling so that at least one of the two probes is below its end of defrosting temperature (dSt for the 1st evaporator and dS2 for the 2nd evaporator) • H45=2: Defrosting is enabled by control- ling so that both the probes are below their respective end of defrosting set points (dSt for the 1st evaporator and dS2 for the 2nd evaporator) The probe error condition is considered the defrost calling probe. When defrosting is terminated by a probe or is timed out (see par. dEt), dripping fol- lows (see par. dt). End of defrosting If two evaporators are used, defrosting ends when both the probes have reached or exceeded their respective end of defrosting set points (dSt for the 1st evap- orator and dS2 for the 2nd evaporator) If one or both the probes are faulty, defrosting is ended by a time-out. NOTE: • If there are no conditions for defrosting, the request is ignored. Defrosting of a single evaporator ends when the value read by the respective probe is equal to or higher than the end of defrosting temperature or a time-out occurs. Dripping starts when both defrosts have been completed. • If one or both the probes are faulty, defrosting in the corresponding evaporator is ended by a time-out. The start of defrosting is permitted when the corresponding temperature is lower than the corresponding set point (dSt or dS2). • If probe 3 is not configured as a probe on the second evaporator (H43 2), defrosting on the second evaporator occurs if a digital output is configured to control defrosting on the second evapora- tor (see par. H21..H25). If this is the case, defrosting is confirmed (as if ST3

CONTROLLER This controller performs diagnostics on an associated digital input using a configura- tion table. It is activated by setting para- meters H11 and H12 = 9. If the pressure switch input trips, the com- pressor loads are immediately deactivated, the alarm LED lights up to signal tripping and the label nPA in the alarm folder appears on the display. Controlling is performed using 2 parame- ters PEn and PEI: nPA is a subfolder of AL (Alarms), and keeps a record of each time the pressure switch is activated if the value indicated by PEn is reached in a period of time that is less than or equal to PEI, the label nPA is replaced by PA (pressure alarm). The alarm conditions only occurs when the maximum number of alarms is reached before the time indicated by parameter PEI expires. As soon as the first alarm occurs, the time PEI is calculated. If the number of times the pressure switch is activated exceeds the number estab- lished PEn in the period PEI: - compressor outputs, fans and defrosting are deactivated - the label PA is displayed in the subfolder nPA - the alarm LEDs and alarm relay if config- ured are switched on. NOTE: Once the device is in alarm mode, it must be switched off and on again or reset by activating the rAP parameter in the functions menu. The nPA folders can be reset using the rPA function in the Fnc folder. NOTE: If parameter PEn is set to 0 the function is excluded and the alarms and counts are disabled. CONDENSER FAN CONTROLLER This controller is associated with probe Pb3 and features: - operating set point - operating differential - exclusion of fans in defrosting mode - start-up delay after end of defrosting If a digital output is set as condenser fans (H21...H24=10) the output will behave as shown below: If probe Pb3 is not present and alarm E3 is active, the controller will always be on during the defrost cycle. Probe 3 can be excluded and the failed connection with the instrument will not trigger an error message. NOTE: During dripping time the output is OFF. NOTE: If a digital output is programmed as condenser fans (H21...H25 =10) parame- ter SA3 is always an absolute value irre- spective of the value of parameter Att. DIAGNOSTICS The alarm condition is always signalled by a buzzer (if present) and the alarm icon LED. The alarms from the faulty thermo- stat control probe (probe 1), the faulty evaporator probe (probe 2), and the faulty display probe (probe 3) appear directly on the instrument display as E1, E2, and E3 respectively. An error condition in probe 1 (thermostat control) causes the following: • E1 code appears on display • compressor is activated as indicated by “Ont” and “Oft” parameters if these are programmed for duty cycle or: The error condition for probe 2 (evapora- tor) causes the following: • E2 code appears on display • end of defrost due to time-out. The error condition for probe 3 (display) causes the following: • E3 code appears on display Other alarms do not appear on the instrument display but can be seen in the “Machine Status” menu in the “AL” folder. The maximum and minimum temperature alarm is regulated according to the ther- mostat control probe (probe1) and/or dis- play probe (probe 3). The temperature limits are defined by the “HAL” (maximum alarm), “LAL” (minimum alarm) and PbA (alarm configuration on probe 1,3 or both) parameters. MAXIMUM AND MINIMUM TEMPERA- TURE ALARM If an alarm condition occurs and alarm exclusion times are not in progress (see alarm exclusion parameters), the alarm icon lights up permanently and the relay that is configured as an alarm is activated. This type of alarm does not affect the reg- ulating in progress. Alarms are considered as absolute (default) values or as values related to the Set point (the distance from the Set point itself) and based on the Att parameter. If the alarms are relative (Att=1), the para- meter HA1 is set to positive values and LA1 to negative values. This alarm condition can be viewed in the folder “AL” with labels “AH1-AL1”. ALARM WITH THRESHOLD (PROBE 3) By setting the PbA=3 parameter an alarm is associated to probe 3. It refers to a spe- cific threshold (defined by the SA3 para- meter). An over-temperature or an under- temperature alarm is generated and the icon is turned on. This alarm condition can be viewed in the “AL” folder with the labels “AH3-AL3”. The alarm is handled as a temperature alarm referring to probe 3: for delays and backswings, refer to standard alarms DEFROST ALARM If the end of defrosting is due to a time- out (rather then because an end of defrosting temperature is detected by the defrosting probe), an alarm is generated and the icon lights up. This condition can be viewed in the “AL” folder with the label “Ad2”. Automatic back swinging occurs when the next defrost starts. By pressing any button during the alarm condition, the signal light disappears. In order to cancel the alarm properly, you must wait until the next defrost. EXTERNAL ALARM The device can also control an external alarm, i.e. from a digital input. If the digital input is enabled, the alarm control is acti- vated by programming and remains enabled until the next time the digital input is deactivated. When an alarm is set off, the alarm icon lights up permanently, a buzzer (if present) and the relay config- ured as alarm are activated and the com- pressor, defrost and fan controllers are deactivated according to the value of the rLOparameter): This alarm condition can be displayed in the “AL” folder using the “EA” label. The relay can be silenced; even if the alarm icon starts blinking, the controllers remain locked until the next time the digital input is deactivated. OPEN DOOR ALARM If a door is open, the Open Door alarm is signalled in response to a delay defined by the tdO parameter. The alarm is signalled by the flashing alarm icon. This alarm con- dition can be viewed in the “AL” folder with the label “Opd”.

zero when the door is closed since if the door is continually opened and closed, any alarms would never be sig- nalled. LINK ALARM In the event of a master/slave/echo com- munication failure, the No Link alarm is signalled. This alarm condition can be viewed on the master and slaves, if pre- sent, in the “AL” folder with the “E7” label. Error status is also signalled by any con- nected echo devices with signal “- - -” appearing on the display. NOTE: •The E7 error is signalled after approx. 20 seconds in “no link” condition to avoid any link disturbance causing communication errors. •The E7 error is also signalled for address- ing conflicts when: a) the number of Slaves set on the MAS- TER is different from the actual number of Slaves on the network b) 2 or more Slaves have the same address. ELECTRICAL CONNECTIONS Warning! Always switch off machine before working on electrical connections. The instrument has screw terminals for connecting electrical cables with a maxi- mum diameter of 2.5 mm2 (only one con- ductor per terminal for power connec- tions): for terminal capacity, see the label on the instrument. The relay contacts are voltage free. Do not exceed the maximum current allowed. For higher loads, use a suitable contactor. Make sure that the power voltage com- plies with the device voltage. Probes have no connection polarity and can be extended using an ordinary bipolar cable (note that if probes are extended this affects the electromagnetic compati- bility (EMC) of the instrument: special care must be used when wiring). Probe cables, power supply cables and the TTL serial cable should be kept separate from power cables. MECHANICAL ASSEMBLY The unit has been designed for panel- mounting. Drill a 29x71 mm hole, insert the keyboard and fix it in place with the special brackets provided. The remote dis- play has also been designed for panel- mounting on a cut-out measuring 45.9 x 26.4 mm. It is pressure-mounted using special brackets. Do not install the instruments in excessive- ly humid and/or dirty locations. They are suitable for use in locations with normal pollution levels. Always make sure that the area next to the instrument cooling slits is adequately ven- tilated. TECHNICAL DATA ID 985/E LX Front protection: IP65.
