Alarm Codes

Shutdown Alarms: Shutdown Alarms are indicated by the
Alarm Display. Shutdown alarms also cause the display and
backlight to flash on and off, and the display will switch from
normal video to reverse video and back to normal video (light
areas become dark and dark areas become light as shown in
Figure 3). Shutdown alarms force the unit into shutdown. The
unit will remain in shutdown and will not restart until the
shutdown alarm is cleared. Exceptions are some engine and
electric shutdown alarms become that log alarms when
switched to the alternate operating mode (diesel to electric or
electric to diesel).
If a shutdown alarm occurs that affects only diesel mode
operation and the unit is switched to electric (either manually
or automatically), 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 becomes a diesel mode shutdown alarm
and prevents unit operation. If the unit is configured for
electric to diesel autoswitch, it automatically starts and runs in
diesel mode if an electric shutdown occurs.
In the same manner, if a shutdown alarm occurs that affects
only electric mode operation and the unit is switched to diesel
(either manually or automatically), 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.
