GP 12 How to Check a Solenoid or Clutch
Description
Use this procedure to check a clutch or solenoid.
Initial Actions
WARNING
Switch off the electricity to the machine. Refer to GP 14. Disconnect the power cord
from the customer supply while performing tasks that do not need electricity. Electricity
can cause death or injury. Moving parts can cause injury.
1. For a clutch, check that the shafts, gears, rolls etc., associated with the clutch are free to
rotate, clean and lubricated where applicable.
2. For a solenoid, check that the solenoid is free to actuate and that the mechanisms associ-
ated with the solenoid are free to move.
Procedure
NOTE: The voltages, PJ numbers, pin numbers and PWB names shown are an example only.
Go to the wiring diagram associated with the RAP for the correct information.
NOTE: When a solenoid is energized in diagnostics, movement is seen. When a clutch is ener-
gized in diagnostics, the sound of the clutch action is heard. If possible, run the motor con-
nected to the clutch to confirm when the clutch is energized.
1. Enter the dC330 output code for the clutch or solenoid. If the clutch or solenoid does not
energize, continue at step2. If the energize of the clutch or solenoid is good, perform SCP
5 Final actions.
2. Figure 1, disconnect PJ202, check for +24V at PJ202 pin 1 on the wiring side of the con-
nector, If the voltage is not correct, perform 01H +24V Distribution RAP.
3. Reconnect PJ202, enter the dC330 output code for the clutch or solenoid, while measur-
ing the voltage between PJ183 pin 4 and the machine frame. If the voltage does not
change when the code is entered, Install a new DADH PWB, PL 5.10.
4. There may be an intermittent fault, perform the actions that follow:
• Check the wiring associated with this circuit. Repair or install new components as
necessary
• Check that all connectors associated with this circuit are correctly and securely con-
nected.
• Operate the clutch or solenoid under normal machine running conditions. If the
clutch or solenoid operates intermittently or with hesitation, install new parts.
• Check that the clutch or solenoid has enough drive to operate the mechanism to
which it is attached, if necessary install a new clutch or solenoid.
