Summary
The PROCESSOR failed to warm up in the programmed time. (Refer to sheet 2 of the SYSTEM
Functional Block/Wiring Diagram.) When power is applied to the IMAGER, the PROCESSOR DRUM turns
on, controlled by the SSR DRUM PROC signal from the MCS BOARD. This pulse-width modulated signal
remains low (active) until the PROCESSOR DRUM RTD indicates that the DRUM is at operating
temperature. (See 28-506 for a description of RTD functions.) The normal warmup process takes from
18–20 minutes. As long as the SSR DRUM PROC signal is low, the K1 SOLID STATE RELAY on the
PROCESSOR INTERFACE BOARD (PIB) routes 120 vac to the DRUM HEATER. (Note that the DRUM
HEATER element circuit includes a resettable THERMAL BREAKER.) The 120 vac is applied through
RELAY K2 on the PIB. The ac power should be present at J1 of the PIB as long as the TOP HOOD
INTERLOCK is closed (HOOD down). The program generates the error as follows: Given the
current-sensed DRUM temperature, the program estimates that with heat turned on the desired
temperature level should be reached within a set time. If it is not, error 28-509 is declared.
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 by only by restarting the IMAGER.
User Action
1. Restart the IMAGER.
2. If the error persists, call Service.
FE Action
1. Is the DRUM warm at all? If not, turn off IMAGER power, open the UPPER HOOD, and:
a. Remove the 3 SCREWS from the END CAP of the HEATER. (Or remove 2 SCREWS and pivot the
END CAP out of the way.)
b. Check the THERMAL BREAKER BUTTON inside the DRUM. If it has popped out, pop it in with a
SCREWDRIVER.
c. Apply power and check 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. Otherwise, go to step 2.
2. Power off and check resistance of the HEATER element (through the SLIP RINGS). Resistance
should be about 30 ohms. If the HEATER element is open, replace the DRUM.
3. Check that the RTD CABLE is plugged into the MCS BOARD (J17).
