Plockmatic BM500 - Fold Roller Motor BM-M6 no Displacement Pulses

Plockmatic BM3050 system 27 August 2019 4. Troubleshooting (RAP)
4-109
BM-015 Fold Roller Motor BM-M6 No Displacement Pulses
Fault code indicates that the Fold roller motor BM-M6 does not receive any displacement pulses.
Initial Actions
• Enter Service Mode and run Motor Diagnostic, that will indicate a more precise fault code.
• Ensure that plugs C.P11, C.P14 and C.P3 on MD6DC PCB “C”
in the Booklet Maker are connected (PL 3.0).
• Ensure that plug D P5 on Interlock PCB “D” in the Booklet Maker is connected.
• Ensure that the Fold Roller Sensor BM-Q9 (PL 6.0) is installed correctly
(REP 6.4 Fold Transmission Module, BM-M6 Fold Roller Motor, BM-Q9 Fold roller sensor & fold transmission chain).
Procedure
Enter Service Mode (GP1) and select Fold roller motor BM-M6 in (GP4) check motors.
Do the Fold Rolls turn?
Y N
• Check Fold Transmission (REP 6.4)
• Go to BM-017 RAP
Disconnect plug C.P14 from PCB “C”.
Measure between J.14-10 and J.14-2 (5V and GND).
The voltage is 5 VDC ± 10%.
Y N
Replace MD6DC PCB “C(PL 4.0).
• Disconnect plug from sensor Q9.
• Check continuity for the red wire at plug Q9 to C.P14-2
• Check continuity for the white wire at plug Q9 to C.P14-11
• Check continuity for the black wire at plug Q9 to C.P14-10
• Check for short circuit between red/white/black wires
• Check for short circuit between red/white/black wires to chassis/GND
There is continuity for all wires and no short circuit
Y N
Replace/Repair wire Harness.
Connect plug C.P14 to PCB “C”.
Measure between the red wire Q9 and the black wire Q9 (5V and GND).
The voltage is 5 VDC ± 10%.
Y N
Replace/Repair wire Harness.
Replace sensor BM-Q9 (PL 6.0).
Replace MD6DC PCB “C(PL 4.0).
