3. 3. 3. 6 Motor Does Not Rotate Failure FIP
2005
Before performing this FIP, ensure that the motor is
not locked or loaded.
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.
3-121
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
Before performing this FIP, ensure that there is no
(mechanical) operation failure for the solenoid.
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.
