3. 3. 3. 6 Motor Does Not Rotate Failure FIP
2005
Enter the DC330 [XXX-XXX] and turn it On.
Is +24 VDC measured between Pin 3(+) of the PWB and GND
(-)?
Y N
Is +24 VDC measured between the Motor Pin 2(+) of the
Motor and GND(-)?
Y N
Is +24 VDC measured between the Motor Pin 1(+) of
the Motor and GND(-)?
Y N
Is +24 VDC measured between the PWB Pin
4(+) of the PWB and GND(-)?
Y N
Replace the PWB.
Check the wire between the PWB Pin 4 and the
Motor Pin 1 for an open circuit and poor contact.
Replace the motor.
Check the wire between the PWB Pin 3 and the MTOTR
Pin 2 for an open circuit and poor contact.
Replace the PWB.
3. 3. 3. 7 Motor Left Running Failure FIP
Turn Off the power. Remove the PWB connector. Is the
resistance 10 Ohm or less between the connector Pin 3 and the
frame?
Y N
Replace the PWB.
Check the wire between the connector Pin 3 and the motor Pin 2
for a short circuit.
If no problems are found, replace the motor.
3. 3. 3. 8 NIP/RELEASE SOLENOID Not Energized
Failure FIP
2004
Is +24 VDC measured between the NIP/RELEASE
SOLENOID Pin 1 (+) and GND (-)?
Y N
Is +24 VDC measured between the PWB Pin 5 (+) and
GND(-)?
Y N
Check +24 VDC inputs of the PWB. If no problems
are found, replace the PWB.
Check the wire between the PWB Pin 5 and the NIP/
RELEASE SOLENOID Pin 1 for an open circuit and poor
contact.
Follow the following FIP when the NIP has a problem.
Go to the DC330 [XXX-XXX] and turn the SOL NIP On.
Is +24 VDC measured between the PWB Pin 4 (+) and GND(-)?
Y N
Go to the DC330 [XXX-XXX] and turn the SOL NIP On.
Before performing this FIP, ensure that the motor is
not locked or loaded.
Before performing this FIP, ensure that there is no
(mechanical) operation failure for the solenoid.
