Troubleshooting Guide
15 - 7
General Guidelines Consider the following guidelines before troubleshooting any condition.
These guidelines may help in resolving the condition quickly: Remem

ber, try the simple things first.
1. Disconnect the injector from external equipment: Disconnect all
cables connected to the injector, including those for the film
changer, monitor, or external start switch.
2. To verify the existence of a condition, check injector operations
before troubleshooting, using the Checkout Procedure located in the
Mark V ProVis Injection System Operation Manual. Follow the steps
that pertain to the major functions of the unit to verify the condition.
3. Remove power for one minute. Allow the unit to reset completely,
then reapply power and retry. The condition could be intermittent, or
caused by a voltage transient. If the condition persists, continue
troubleshooting.
4. Open the Control Unit to remove/re-seat the cards. Remove each
circuit card. While the cards are out, ensure that the socketed IC’s
are fully inserted. Reseat the cards, ensuring that the cards are fully
inserted into the connectors on the Mother Board. Replace the card
retainers.
5. The injection system is equipped with self-diagnostic software. A
combination of safety circuits and software, provide the system with
a diagnostic package that detects performance degradation, as well
as total failures of portions of the system. Through Sentinel mes
-
sages, the injector indicates self-diagnosed failures.
6. Any Sentinel message can symbolize a fault within the system. For
example, if the Sentinel displays CHECK TURRET, when the turret
is properly positioned, there may be a defective limit switch in the
head. Watch for messages that contradict the obvious.
7. Some faults can be caused by a noisy electrical environment. For
example, a memory error can be caused by a momentary power fail
-
ure or drop, electrical noise in the power line, or noise in external
interfaces.
8. Check power supplies at the Power Supply Card.
