8-5-25. 20-208: DOOR Fail Open
LOCAL PANEL Message
Front Door Failed to Open--
Alarm sounds
Summary
The FRONT DOOR failed to open after the user pressed the Open Door key. The status of the door is
monitored by the FRONT DOOR INTERLOCK SWITCH. After the FRONT DOOR is manually opened and
closed, the SYSTEM will resume normal operation.
Result of Error
The SYSTEM is unable to print. Otherwise it can operate as normal (acquiring, queueing prints,
completing processing, etc.). New films will not be initiated.
User Action
1. Open the DOOR manually.
2. If the error persists, call Service.
FE Action
Check the MCS Log to attempt to isolate the problem. This error can be generated by any of the following
problems:
1. A failed FRONT DOOR or REAR PANEL INTERLOCK (or INTERLOCK wiring), which indicates to the
SYSTEM software an erroneous DOOR Status (i.e., information that the DOOR is already open). In
this case the MCS BOARD will not deliver an "Open Door" command to the DOOR RELEASE
SOLENOID.
2. A failed DOOR RELEASE SOLENOID or FET DRIVER for the SOLENOID (located on the MCS
BOARD). In this case the MCS BOARD sends the "Door Open" signal, but the SOLENOID cannot
respond.
Note
The DOOR RELEASE SOLENOID can fail in either an open or shorted state. If the SOLENOID is
shorted, you will not be able to close the FRONT DOOR. If a SOLENOID fails, it will probably
damage the FET DRIVER on the MCS BOARD, so both the SOLENOID and MCS BOARD will have
to be replaced.
