Page 2 BCM500/2x7 Bodymaker System DESCRIPTION BCM 500 BODYMAKER CONTROL MODULE The BCM500 is an expansion of the capabilities of the 387-S1 Bodymaker Sensor System. The module supports the following functions: • short can and tear-off detection • dome jam detection • airstrip function. This manual explains how to configure a BCM500 for use with a ‘non-smart’ 2x7 and 487 short can sensor, this includes the 247, 267, 287 and 487 series sensors. The BCM500 receives Air Strip, Backstop and Short Can timing signals from the Autotech or other type of timing switch, together with signals from the Short Can and Dome Jam Sensors. It provides outputs direct to the Clutch and Airstrip Solenoids, together with outputs to the PLC to indicate: • Loss of Calibration - only when using a Smart Sensor for Aluminium Cans • Short Can - a marginally short can • Misfeed/Tear Off - no can was made at all or it was a very short can • Dome Jam • Can Jam or Short Can Sensor Fault - an output was detected from the Short Can Sensor at a time when no can should have been present. (The Can Jam condition can only be detected when using a “non-smart” sensor) The BCM500 must be correctly set according to the type of sensor in use (PNP or NPN) and various other parameters. These are set on links inside the module, details are given in this manual. In addition to this the BCM500 has to be set according to the type of Short Can sensor connected, this may be: • 387 "Smart" Sensor for Aluminium on Carbide or steel • 487 “non-smart” sensor for Aluminium on Carbide • 287 "non-smart" sensor for Aluminium on Carbide • 267 "non-smart" sensor for Steel on Carbide. • 247 "non-smart" sensor for Aluminium on steel. This setting can only be altered by using software available from Sencon, which communicates with the BCM500 via its serial port. The Bodymaker Control Module offers two modes for stopping the Bodymaker: • Immediate stop mode stops the machine when a can defect is detected. The module immediately opens two transistor switches that can interrupt up to 2 Amperes at 24 Volts when a defect is detected. • Timed stop mode synchronizes stopping the machine with the leading edge of the backstop window.

Page 5 BCM500/2x7 Bodymaker System INSTALLATION MECHANICAL INSTALLATION ELECTRICAL INSTALLATION The inputs and outputs to the BCM500 are shown here. Electrical connection is made to the unit with screw terminals. The terminals are recessed to reduce the chances of accidentally contacting them. +VS 0VS Sensor Output 09-487-00 Red Black White 11-487-00 Brown Blue Black 9-247-03 9-267-03 9-287-03/33/53/63 Red Black Green – source 11-247-03 11-267-03 11-287-03/33/53/63 Brown Blue Black – source The 0V, 0VI, and 0VS terminals are common to each other. However, do not use the 0VI or 0VS terminals for power loads. They are intended for low-level signals only. The outputs are optically isolated from the supply voltage and the inputs. The COM terminal can be connected to an AC lead, to a DC lead, to the 0V terminal, or to the +VIN terminal.

Page 6 BCM500/2x7 Bodymaker System 2x7 Sensor Interconnection Make sure to seat fully and tighten the cable connector on 11 series sensors. Also install and clamp the hydraulic tubing over the fitting. Otherwise, liquid may infiltrate the connector and degrade performance. DC Signal Inputs Configure the input signals as shown in the diagram below. Settings are made with mini-jumpers accessible under the top cover of the unit. Remove the top cover by inserting a flat screwdriver blade in the slot shown and rotating the blade to `pop' the cover off. This operation MUST be done with power off to avoid damaging the unit. Note: Alternative input setups are possible. Consult the factory for details. If an input is active high, the flow of current at the input terminal is ON, and no current flow at the input terminal is OFF. The reverse is true if an input is active low. The transition from OFF to ON is the leading edge of the signal. The transition from ON to OFF is the trailing edge of the signal.

Page 7 BCM500/2x7 Bodymaker System Solid State Switch Outputs These outputs are optically isolated from the supply voltage. Therefore, the COM terminal is floating and can be connected to any reference that falls within the specified voltage range. FET Transistor Switch Outputs There are three FET transistor switches for control of the Bodymaker clutch/brake solenoids and the air strip solenoid. The contacts are FET transistors that are optically isolated from the internal power supply. IMPORTANT SAFETY NOTICE - The transistor switches provided with this unit must not be the only means of controlling the Bodymaker clutch mechanism. Good design practice dictates the use of safety lockouts on any device that starts and stops automatically that can cause personal injury to operating or maintenance personnel. The BCM500 must be used only with industry approved safety lockout contacts, otherwise serious personal injury may result.

The Bodymaker Sensor System requires the ten inputs described here. These inputs are not optically isolated from the BCM500 internal power supply. Input Description SCT The Short Can Timing window is active when the punch is in position for sensing. The rising edge of the window signal corresponds to the can body trimline. NOTE: THIS INPUT IS ALWAYS ACTIVE LOW. BST The Back Stop Timing window allows a synchronous stop of the machine. The clutch outputs open on the falling edge of this signal in the Timed Stop mode. NOTE: THIS INPUT IS ALWAYS ACTIVE LOW. AST The Air Strip Timing window is active during the stroke for the period that allows the can to be blown off the punch. NOTE: THIS INPUT IS ALWAYS ACTIVE HIGH. DJI The BCM500 checks the Dome Jam Input from the end of the SCT window until the end of the AST or BST windows. Therefore, either of these windows must be active just past 180 degrees of the machine cycle to detect a dome jam. RES The Reset/Override input clears all faults and closes the appropriate output switches. While the Reset/Override input is active, no tear-offs, short cans, or dome jams are detected. After a fault, this input must be activated before restarting the Bodymaker. The CE input must also be active to close any output driver switch. CE The Clutch Enable Input must be active to initiate a machine stroke. The Bodymaker stops immediately when the CE changes from active to inactive in the Immediate Stop mode. The Bodymaker stops on the leading edge of the BST window in the Timed Stop mode. ASE The Air Strip Enable must be active to close the air strip switch. CAL This input is only used for 387 sensors. The Calibrate input sends a calibrate command to the sensor and checks for a good calibration output from the sensor. When a good calibration is detected by the module, the calibrate output closes. This takes at least four cycles. The Calibrate input must be shutoff before the cup feed turns on. An active Calibrate input puts the module in the Reset/Override mode. I/T The Immediate Stop mode stops the machine immediately by opening transistor switches CO1 and CO2 when a defect is detected. The Timed Stop mode synchronizes the operation of CO1 and CO2 with the leading edge of the BST window. SIN The Sensor input is for a source or push-pull only sensor output. This input from the sensor is normally ON (high) during the SCT window.

The Bodymaker Control Module has four solid state switch outputs. These outputs are bidirectional and isolated from the BCM500 internal power supply. They can be wired for DC source, DC sink, and AC. These outputs are rated for 40 mA (maximum) at up to 240 VAC (peak) or 240 VDC. Input Description CAL The Calibrate output is ON (current flow allowed) after the sensor has been calibrated and remains ON while the sensor calibration is good. This output is only used for 387 sensors. DJO The Dome Jam Output is OFF (no current flow allowed) after a dome jam is detected and remains OFF until a reset signal is applied. SC2 The SC2 output is OFF (no current flow allowed) after a short can is detected and remains OFF until a reset signal is applied. SC1 The SC1 output is OFF (no current flow allowed) after a tearoff is detected and remains OFF until a reset signal is applied. Note: If the sensor fails, or a can jam is detected, all of the logic outputs turn OFF. The BCM500 will detect a can jam if the Short Can sensor is still seeing metal by the time all three timing signals it receives have completed "one cycle". “One cycle” is deemed to begin when the first timing signal becomes active and ends when the last timing signal becomes inactive. This cycle is therefore entirely dependent upon the timing set-up of each bodymaker. The system cannot distinguish between a Can Jam and a faulty Short Can sensor which has failed with its output turned on If the sensor is not faulty, and there is no can jam, the apparent fault can be caused if the can remains held in the Dome Station by excessive Strip Air pressure or duration, or by the take away conveyor timing if it is slightly late. One remedy for this which can be applied with caution is to increase the time allowed for the can to be taken away before such a fault is detected by lengthening the Backstop timing windows. When a Can Jam or Short Can Sensor fault is detected this is indicated by all the outputs "Short Can," "Misfeed/Tear Off," "Dome Jam" and "Calibration" switching off together. TRANSISTOR SWITCH CLUTCH/SOLENOID CONTROL OUTPUTS The driver outputs are FET transistor switches and are isolated from the supply power. The rated load is two amperes maximum at 30 volts. Polarity must be observed. Input Description DR4 The DR4 driver is currently not in use. This is reserved for future expansion. ASO The Air Strip Output is closed while the AST window and the ASE inputs are active. CO2 Clutch Output 2 is closed while the CE input is active and the RES has cleared any faults. It remains closed until the CE input goes inactive or a fault occurs. When a fault occurs, the output opens immediately (Immediate Stop) or opens synchronized with the leading edge of the BST window (Timed Stop). CO1 Clutch Output 1 follows CO2.

The system normally does a full can check when it is evaluating a can for defects. The sensor normally profiles the punch at various points during the SCT window. Trimline check differs from this in that only the trimline is evaluated. The system can be forced into trimline check with the Trimline Mode Select jumper. The system logic output SC1 indicates a tearoff when it occurs, even with the system in trimline check. This signal provides information about where the tearoff occurred along the punch. However, the clutch outputs CO1 and CO2 open only if the trimline check fails. POWER UP The BCM500 must receive a RES input or a CAL input after power up. Otherwise, the unit will not engage any of the clutch outputs. SYSTEM TIMING DIAGRAMS System Power Up Timing The power up diagram only applies to sensors with the calibration values saved internally in EEPROM. Sensors without this capability must be calibrated every time the supply power is turned on. Good Run Timing The maximum cycle time is 260° at 600 CPM for all three timing windows. The minimum SCT window time is 5 msec. or 18° at 600 CPM. The dome jam check begins at the end of the SCT window and continues while either the AST or BST signals are active.

The immediate stop mode is for use where the machine can stop asynchronously to the backstop timing window Normal Clutch Enable Stop in Timed Mode Use the timed stop mode when the machine must stop synchronously to machine backstop timing.

Note that the SC2 output indicates a fault in Trimline Mode although the fault detected is a tearoff. Tearoff Shutdown in Immediate Mode Tearoff Shutdown in Timed Mode

In Inch mode or Bar mode, RESET must be held high (ON) and the clutches (CO1/2) follow the CE signal. I/T must be held low (OFF). The CE signal is scanned and updated every 2.5 msec. Single Stroke Mode with No Cups In single stroke mode the I/T input must be held high. The minimum time the CE window must be active is 10 msec. The SCT window must be completed before the clutches (CO1/2) can be disengaged. This guarantees one complete cycle no matter where the machine is positioned before the single stroke is invoked. The BST input is edge triggered, so single stroke can only be done at low speed where the BST window goes active after the SCT window is completed. No faults are detected. I

Single stroke mode with the cup feed on follows all requirements of a single stroke without cups except that the RESET input is inactive. Tearoffs and dome jams are detected and latched until a RESET signal is applied. To do a single stroke with the cup feed on, all faults must be cleared.

follow when replacing the sensor or the punch. INSTALLING A REPLACEMENT 2x7 or 487 SENSOR Install a replacement 2x7 or 487 sensor as shown in the ‘Installation’ section of this manual. Make sure the connector is fully seated and that the hose and clamp are secured properly. FAULT FINDING Symptom Possible Cause 1 Can Jam or Short Can Sensor fault is indicated when there is no problem. This fault is only indicated when using a non smart sensor in conjunction with a BCM500 – this would be the case if making Steel cans. The fault is indicated when a can is seen by the sensor on the backstroke. This can happen for a number of reasons: • if the mechanical timing of the take away conveyor is slightly late • If the can is being held against the Dome Station for excessive Air Strip pressure or duration 2 Machine does not stop in a repeatable position –particularly if it takes a long time to stop on a System Stop This is usually because the machine is being stopped by the Clutch Safety Relay rather than by the transistor outputs in the BCM. If this happens it may be that the Backstop signal is not reaching the BCM, or that the polarity of the transistor outputs for the clutches is wrong. If connected with the wrong polarity, they conduct all the time through their protection diodes 3 The machine stops and the three lights, SC1, SC2 and CAL all blink off This indicates either: • A fault in the pattern of timing signals reaching the BCM (i.e. Short Can, Backstop and Airstrip) • A fault in the BCM500 • A Can Jam – Cause 1 above

To reconfigure the BCM500 special software is required to allow communication between a PC and the BCM500. A Sencon ‘Brown’ Cable (212-00902-00) can be used. Otherwise the connections required are as follows: 1. With power off to the BCM500 remove the top cover of the BCM and connect to the PC 2. Remove the first mini-jumper from the BCM500, marked "1". On page 7 of the Sencon BCM500 Manual this jumper is marked "Do Not Remove" however it must be removed to allow programming of the BCM500. 3. Turn power on to the BCM500 4. Install the Sencon program by running BCMConfig Setup.msi. A short cut will be placed on the PC desktop. 5. After installation run the BCMConfig application 6. When communications are established click on the 2X7 Non-Smart Sensor when using 247, 267, 287 and 487 series sensors. 7. Click the Save button 8. Click Exit to quit. 9. Remove Power to the BCM500 10. Replace jumper 1. in the BCM500. All other jumpers should be left unchanged. 11. The unit is now configured. 12. When using 247, 267, 287 and 487 series sensors "Calibration" of the sensor is no longer needed, but it is recommended that no changes are made to the PLC program in case production is ever changed back.
