0--Fatal
Summary
The DRUM temperature is too high and the PROCESSOR HEATER has been turned off. When power is
applied to the IMAGER and the TOP HOOD is closed, 120 volts ac is applied to the PROCESSOR
HEATER through a RELAY on the PROCESSOR INTERFACE BOARD, under control of the MASTER
CPU on the MCS Board. The PROCESSOR RTD senses changes in HEATER temperature and reports
them to the MASTER CPU. Failure to control temperature probably indicates that the RTD is open, there
is a short in the DRUM wiring, or a control circuit on the MCS BOARD is defective.
Result of Error
The IMAGER is unable to print film. It can accept and queue new jobs, but it will not initiate new films. All
films in the IMAGER will be reprinted. The error can be cleared only by restarting the IMAGER.
Related Errors
•
28-506 PROCESSOR Communication Failure — RTD timed out while communicating PROCESSOR
temperature to MCS.
•
28-509 PROCESSOR Warmup Failure — Desired temperature level was not reached within set time
(18--20 minutes).
•
28-551 PROCESSOR DRUM HEATER Failure — HEATERS did not warm up at the desired rate of
1.5
_
C every 30 seconds.
User Action
1. Restart the IMAGER.
2. If the error persists, call Service.
FE Action
Check for a possible short in HEATER wiring as follows:
1. Power down and open the TOP HOOD.
2. Remove the 3 SCREWS from the END CAP of the HEATER. (Or remove 2 SCREWS and pivot the
END CAP out of the way.)
3. Check the THERMAL BREAKER BUTTON inside the DRUM. If it has popped out, use a
SCREWDRIVER to pop it back in.
4. Apply power and check to see if the BREAKER BUTTON pops back out. If it does, there is probably a
short in the HEATER wiring, and the DRUM should be replaced.
5. With a multimeter connected to TP8 on the MCS BOARD, monitor the voltage as the drum warms up.
Normally, during warmup, the voltage increases steadily in small increments (about 0.1V), and the
green LED on the PIB is constantly illuminated. When the PROCESSOR reaches temperature, the
LED flashes on and off. If there is a sudden voltage spike (up to 5V) during warmup, suspect a failed
RTD . Replace the DRUM, and monitor again.
Check for other possible causes:
•
Low ambient room temperature where the IMAGER is located.
•
Low AC supply at the RECEPTACLE (AC supply below spec).
