Fault 251—Back det: non-det module
Status message: F det wrong module or B det wrong module
The module installed in an inlet slot is unusable. Two things could cause this
condition:
• The module is installed in the wrong position. For example, a detector
module might be installed in the inlet position.
• If the correct module is installed, it may be malfunctioning or its EEPROM
may be unrecognized by the 6890 GC.
❐ Make sure that the correct type of module is installed.
