Plockmatic BM3050 system 27 August 2019 4. Troubleshooting (RAP)
4-155
Fault code indicates that there is a communication lost problem.
Initial Actions
• Ensure that the communication cable between the
Booklet Maker and the Square Folder is properly connected (see Installation).
Make sure dip/switch at PCB “V” is correctly set. Check BSD in section 8.
• Ensure that the communication cable between the
Square Folder and the Trimmer is properly connected (see Installation).
• Ensure the power to Booklet Maker and Square Folder is connected (see Installation).
• Ensure the power between Square Folder and Trimmer is connected (see Installation).
BM-157 Trimmer Communication Lost
Procedure
Power on the machine, inside Trimmer, measure 12VDC between A.P4-4 and A.P4-5.
The voltage is 12VDC ± 10%
Y N
Go to No 12VDC RAP in Trimmer section
• Power off, inside Trimmer disconnect A.P6 and A.P7,
uninstall communication cable(s) between machines and disconnect both CAN terminations.
• Use the BSD to locate connectors/pins and measure continuity
between all wires from A.P6 to J23 and between A.P7 to P24.
• Check for short circuit between all wires from A.P6 and A.P7 to chassis and
between different pins at J23. Check for short circuit between different pins at P24.
There is connectivity and no short circuit
Y N
Repair/replace harness
• Measure continuity for all wires in the communication cable(s),
it could be one or two communication cables depending on system setup,
pin 1 to 1, 2 to 2, 3 to 3, 5 to 5 and 7 to 7.
• Check for short circuits between the different pins,
and from pin 1, 2, 5 and 7 to the connector housing (not pin3).
There is connectivity and no short circuit
Y N
Replace the failed communication cable(s) (PL 10.7).
Leave CAN terminations disconnected, at both CAN terminations measure resistance between pin 2 and pin 7.
The resistance is 120R ± 10%
Y N
Replace the failed CAN termination connector(s)
There is a Square Folder installed
