UNIT OPERATING INSTRUCTIONS PREMIUM HMI CONTROLLER
(Light areas become dark and dark areas
become light.)
• The remote indicator alarm light (if installed)
will display only a row of LEDs at the
bottom.
Shutdown alarms will force the unit into
shutdown to prevent potential damage to the
unit or load. The unit will remain in shutdown
until the shutdown alarm is manually cleared.
Exceptions are some engine and electric
shutdown alarms that become log alarms when
switched to the alternate operating mode (diesel
to electric or electric to diesel).
Zone Level Shutdown Alarms
(SPECTRUM)
A Zone Level Shutdown Alarm will force the
affected zone to shutdown, but allow the unit to
continue to run as required by the host unit or
other zones.
• A small Alarm Icon will appear next to the
affected zone
• and blink with a period of 1/2 second on - 1/
2 second off.
• If a Zone Shutdown Alarm occurs in all
zones then the
• unit will shut down and Alarm Code 114
Multiple Alarm
– Can Not Run will be set.
PREVENT ALARMS
Prevent Alarms are also indicated by a steady
Alarm Icon in the display. The remote
indicator alarm light (if installed) will be on.
The unit will attempt to resolve the situation as
shown below.
• The unit will be temporarily shut down if a
Prevent Alarm is active.
• 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 reoccur 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.
Note: If the Restart After Shutdown feature in
the Guarded Access Menu is set for
CONTINUOUS, then an unlimited number of
restart attempts are allowed.
Pretrip Alarm Codes
If an alarm occurs during a Pretrip Test the
alarm code will be displayed as Pretrip Alarm
XX, where XX is the alarm code.
Zone Level Prevent Alarms (SPECTRUM)
A Zone Level Prevent Alarm will force the
affected zone into a temporary shutdown, but
allow the unit to continue to run as required by
the host unit or other zones.
• A small Alarm Icon will appear next to the
affected zone.
• If a Zone Prevent Alarm occurs in all zones
then the unit will be forced into a unit level
Prevent shut down.
