Procedure
Execute Component Control [042-001 Main Motor ON]. The Main Motor can be heard.
YN
Check the connections of P/J410 and P/J214. P/J410 and P/J214 are connected cor-
rectly.
YN
Connect P/J410 and P/J214.
Check the wire between J410 and J214 for an open circuit or a short circuit (BSD 4.1B)
The wire between J410 and J214 is conducting without an open circuit or a short
circuit.
YN
Repair the open circuit or short circuit.
Measure the voltage between P/J214-1 and P/J214-2 on the Main Motor. The voltage
is approx. +24VDC.
YN
Measure the voltage between the Relay PWB P/J451-5 (+) and P/J451-6 (-) (BSD
4.1B).
The voltage is approx. +24VDC.
YN
Measure the voltage between the P/J450-4 (+) and P/J450-2 (-) on the Relay
PWB, (BSD 1.2B).
The voltage is approx. +24VDC.
YN
Go to 7.3.27 Wire Net +24VDC-6. Troubleshoot the circuit between P/
J510-3 and P/J450-4 for +24VDC.
Replace the Relay PWB (PL 11.1).
Check the wiring connectors between P/J451 pins 5 and 6 and P/J214 pins 1 and 2
for an open or short circuit.
The wiring and connectors are OK.
YN
Repair or replace as required.
Replace the Main Motor (PL 1.1).
Measure the voltage between the MCU PWB P/J410-A5 (+) and GND (-) (BSD 4.1B).
The voltage is approx. +5VDC.
YN
Go to BSDs 1.2A and 1.2B and check the +5VDC distribution. +5VDC distribution
is OK.
YN
Repair or replace as required.
Replace the MCU PWB (PL 11.1).
Replace the Main Drive Assembly (PL 1.1) If the problem persists, replace the MCU PWB
(PL 11.1).
Check the following wires for an intermittent circuit:
• Between J410-A1 and J214-10 (BSD 4.1B)
• Between J410-A2 and J214-9 (BSD 4.1B)
• Between J410-A3 and J214-8 (BSD 4.1B)
• Between J410-A4 and J214-5 (BSD 4.1B)
YN
Repair the open circuit or short circuit.
Replace the Main Drive Assembly (PL 1.1) If the problem persists, replace the MCU PWB (PL
11.1).
