PPI RECALL CHECKSUM ERROR
The injection program saved in PPI memory does not match the pro-
gram loaded in the system RAM. Clear the program from PPI memory
using RECALL 52, then attempt to reenter the program.
PREMATURE TERMINATION
An injection was interrupted before the selected Volume had been
injected. The handswitch or remote start switch was released before
the injection completion. Repeat the injection if possible.
Service Procedure:
1. If the condition persists, suspect an intermittent connection
in the start circuit, or electrical interference on the start or
power lines.
2. If an external start is being used, ensure that it remains
closed throughout the injection.
**P.S.I. LIMIT EXCEEDED
Actual Pressure has exceeded the selected Pressure by at least 100

2. If the condition persists, replace the Power Drive Card.
**PWR DRIVE FAILURE
A Fault occurred in the injector motor drive circuits during an injection.
Remove power from the injector for 10 seconds, reapply power, and
retry.
Service Procedure:
1. If the condition persists, replace the Servo Control Card.
2. If the condition persists, replace the Power Drive Card.
3. If the condition persists, check the injector head cable for
broken or intermittent connections. Carefully inspect the
plunger motor leads.
4. If the condition persists, replace the injector head.
