Summary
The PROCESSOR RTD timed out while measuring PROCESSOR temperature and communicating it to
the MCS. (Refer to sheet 2 of the SYSTEM Functional Block/Wiring Diagram.) The PROCESSOR RTD
changes resistance with changes in DRUM temperature. An AMPLIFIER senses the resistance changes
on the MCS BOARD as voltage changes. A voltage--to--frequency circuit then converts the RTD input to a
square--wave--frequency signal. This signal (PROC TEMP FREQ IN) represents DRUM temperature to
the CPU of the MCS. The CPU samples this signal once a second, counting the pulses for 100ms. If the
square wave pulse goes to steady-state DC for longer than a second, error 28-506 is declared. Power is
applied to the processor HEATER and MOTOR 11 seconds into the power--on cycle. (Refer to Figure 7-3,
MCS Self-Test Startup.)
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. De-energize the IMAGER and check CONNECTORS and wiring between the MCS BOARD (J17) and
the RTD.
2. Use an OHMMETER to check that the RTD is not open. Resistance across the RTD should be 1k to
1.7K. If the RTD circuit is open, replace the DRUM ASSEMBLY.
