Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the Duplex Clutch operation.
Perform DC330 Component Control on
page 2-26 [071-017] to check the operation of
the Duplex Clutch.
Is the Duplex Clutch operating properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the connection between the Duplex Clutch
and Duplex PWB.
Is the connector P/J431 connected securely?
Go to step 3. Connect the connector
P/J431.
3. Check the resistance value of Duplex Clutch.
Turn Off the power, remove the Duplex Clutch
(REP 14.4 Duplex In Clutch Assembly/ Duplex
Drive Gear Assembly Kit on page 4-254), and
check the wire resistance between the two
terminals.
Is the resistance approximately 280 Ohms (at
68° F)?
Go to step 4. Replace the Duplex
Clutch (REP 14.4
Duplex In Clutch
Assembly/ Duplex
Drive Gear Assembly
Kit on page 4-254).
4. Check the voltage supply (+24VDC) to the
Duplex Clutch.
Measure the voltage between the Duplex PWB
GND <=> P/J431-1.
Is there a voltage (approx. +24VDC) output?
Close the Interlock Switch and check.
Replace the Duplex
Clutch (REP 14.4
Duplex In Clutch
Assembly/ Duplex
Drive Gear Assembly
Kit on page 4-254).
Go to step 5.
