Section 4 – SR-2 Operation
Alarms
Alarms may be one of four types as shown below.
Log Alarms
Log Alarms
are indicated at the top of the display for 30 seconds each time the unit is turned on. The remote
indicator alarm light will also be on during this period. The alarm indication will go off after 30 seconds. This level
of alarm serves as a notice to take corrective action before a problem becomes severe. Maintenance items such
as maintenance hourmeter time-outs are log alarms.
Check Alarms
Check Alarms are indicated by a steady alarm indication at the top of the display and the message “Service
Required within 24 Hours”. This level of alarm serves as a notice to take corrective action before a problem
becomes severe. The unit will run with check alarms but some features and functions may be inhibited. The
temperature watch screen is disabled if a check alarm is active.
Prevent Alarms
Prevent Alarms are indicated by a steady alarm indication at the top of the display and the message “Unit in
Prevent Mode”. The unit will wait a timed restart interval or until conditions allow and then restart. If the unit is in
a restart interval Alarm Code 84 Restart Null will be present along with the Prevent Alarm. In most cases the unit
will restart with reduced performance to determine if continued operation is possible. If the alarm does not
reoccur with reduced performance the unit will then return to full performance. If the unit is operating with
reduced performance Alarm Code 85 Forced Unit Operation will also be present under some conditions. 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. The temperature watch screen is disabled if a check alarm is active.
Shutdown Alarms
Shutdown Alarms
are indicated by a flashing alarm display and the message “Unit Not Running - Service
Required”. Shutdown alarms will force the unit into shutdown. The unit will remain in shutdown until the shutdown
alarm is 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). The temperature watch screen is
disabled if a check alarm is active.
