Prelaunch Training/Review
Status Indicator RAPs
OF 99-8 Nip / Release Solenoid Open
Procedure
NOTE: Before performing this RAP, ensure that there is no (mechanical) operation failure for
the solenoid.
There is +24VDC measured between the Nip/Release Solenoid Pin 1 (+) and GND (-).
YN
There is +24VDC measured between the PWB Pin 5 (+) and GND(-).
YN
Check +24VDC inputs on the PWB. If the check is OK, replace the PWB.
Check the wire between the PWB Pin 5 and the Nip/Release Solenoid Pin 1 for an open
circuit or poor contact.
Enter DC330 [XXX-XXX]. There is +24VDC measured between the PWB Pin 4 (+) and
GND(-).
YN
There is +24VDC measured between the Nip/Release Solenoid Pin 3 (+) and GND (-
).
YN
Replace the Nip/Release Solenoid.
Check the wire between the PWB Pin 4 and the Nip/Release Solenoid Pin 3 for an open
circuit and poor contact.
Follow the following when the RELEASE caused a problem.
Go to the DC330 [XXX-XXX]. There is +24VDC measured between the PWB Pin 6 (+) and
GND(-).
YN
There is +24VDC measured between the Nip/Release Solenoid Pin 2 (+) and GND (-)
YN
Replace the Nip/Release Solenoid.
Check the wire between the PWB Pin 6 and the Nip/Release Solenoid Pin 2 for an open
circuit or poor contact.
Replace the PWB.
