Diagnostic Codes
As shown below, a "LATCHING" diagnostic is a condition which
causes the machine or a portion of the machine as noted to shut down
and requires a manual reset to restore operation. A diagnostic that is
non-latching resets automatically when the condition causing the
diagnostic goes away. A non-latching diagnostic shuts down the
machine or a part of the machine if so indicated. If a diagnostic is
informative only, no machine or circuit action is taken except to load a
diagnostic code into the last diagnostic register.
Unless otherwise stated, all active diagnostics will be lost on loss of
power.
DIAGNOSTIC T PES AND ACTION:
MMR = MACHINE SHUTDOWN - MANUAL RESET
MAR = MACHINE SHUTDOWN - AUTO RESET
IFW = INFORMATION - WARNING May or may not affect machine
operation; lowest level of diagnostic.
Remotely Resettable Diagnostics:
Except for the following, all diagnostics can be reset remotely from
either the Remote Clear Language Display or the Tracer. The
following diagnostics shall only be resettable ONLY at the local Clear
Language Display, e.g., with the operator standing at the unit.
