Diagnostics
In the table following, a “Latching” diagnostic is a
condition which will cause the machine or a portion of
the machine as noted to shut down and will require a
manual reset to restore operation. A diagnostic that
is non-latching is reset automatically when the
condition causing the diagnostic goes away. A non-
latching diagnostic will shut down the machine or a
part of the machine if so indicated. If a diagnostic is
information only, no machine action is taken.
Unless otherwise stated, all active diagnostics will be
lost on loss of power.
Diagnostic Types And Action
MMR = Machine Shutdown - Manual Reset
MAR = Machine Shutdown - Auto Reset
IFW = Information Warning - May affect machine
operation; lowest level of diagnostic

Except for the following, all diagnostics can be reset
remotely from either the Remote Clear Language
Display, the Tracer, or the External Diagnostic Reset
input at the Options Module. The following
diagnostics shall only be resettable ONLY at the
