Section 3 – SR-2 Software Description
Programmable Features Menu
The Programmable Features Menu allows overall
unit operation to be configured to specific end user
requirements. These features are set to factory
defaults when shipped, but can easily be changed to
suit the end user’s needs. Programmable features
are designed to allow the user to customize some
unit operating parameters without using OptiSet
IMPORTANT
If a feature has been programmed in OptiSet, the
HMI will display “programmed in OptiSet”, and
the feature cannot be updated from this menu.

Description Standard restart alarms become
permanent shutdown alarms after several attempts
to start and run. The continuous feature is designed
for rail applications where the unit runs unattended
or is inaccessible for service. It allows unlimited
restart attempts to be made if the following restart
alarms occur:
Alarm Code 10 High Discharge Pressure
Alarm Code 18 High Engine Coolant Temp
Alarm Code 63 Engine Stopped
Alarm Code 82 High Compressor Temp
If restarts are disabled, the unit will shut down on the
first alarm event.
The following differences exist between a Standard
Restart alarm and a Continuous Restart alarm:
• Standard Restart alarms force a permanent
shutdown if the alarm occurs a pre-determined
number of times (usually 3). Continuous Restart
alarms allow an unlimited number of restarts.
• Standard Restart alarms typically use a 15
minute timer before a restart is allowed.
Continuous Restart alarms use a 1-hour timer
before a restart is allowed.
• With Continuous Restart alarms ETV Head
Pressure Setpoint is lowered based on the
alarm type and number of occurrences.
