• The unit will remain shut down for a timed restart interval or until the
fault conditions are corrected.
• If the unit is in a temporary shutdown, Alarm Code 84 Restart Null will be
present along with the associated Prevent Alarm.
• The unit will restart and run (in most cases with forced reduced
performance) to determine if continued operation is possible. The unit
will run in this manner for a timed interval. If the unit is running with
forced reduced performance, Alarm Code 85 Forced Unit Operation will
also be present under some conditions.
• If the alarm does not re-occur during the timed running interval with
reduced performance, the unit will return to full performance to
determine if continued operation is possible. The unit will run in this
manner for a timed interval. If the unit is successfully able to return to full
performance for the timed interval without the alarm re-occurring, the
alarm is auto cleared and the unit will run normally.
• All Prevent Alarm events and conditions are logged by the ServiceWatch
Data Logger.
• In general, if the alarm condition re-occurs a defined number of times,
the alarm is set as a Shutdown Alarm and no further restarts are
possible.

set for CONTINUOUS, an unlimited number of restart attempts are
allowed.

unit is switched to electric, the diesel mode Shutdown Alarm becomes an
electric mode Log Alarm. This allows the unit to run in electric mode without
clearing the Shutdown Alarm that is preventing diesel mode operation. If the
unit is switched back to diesel mode, the alarm again become a diesel mode
Shutdown Alarm and prevents unit operation.
In the same manner, if a Shutdown Alarm occurs that affects only electric
mode operation and the unit is switched to diesel, the electric mode
Shutdown Alarm becomes a diesel mode Log Alarm to allow diesel mode
operation. If the unit is switched back to electric mode, the alarm reverts to
an electric mode Shutdown Alarm and prevents unit operation. If the unit is
