Start-Stop Operation
Enable Start-Stop mode to reduce fuel or power consumption
Start-Stop Operation allows the unit to automatically shut down near setpoint and restart when needed. This reduces fuel or power consumption while maintaining temperature. The control system monitors compartment temperature, battery charge condition, and engine coolant temperature (Engine Operation only) to manage shut down and restart.
With the system powered up (START/RUN-OFF switch in the START/RUN position) or in PC mode, press the START-STOP/CONTINUOUS key until "START/STOP" is highlighted.
The message "START/STOP MODE SELECTED" will be displayed in the MessageCenter for 10 seconds.
The operation indication in the status bar will no longer be highlighted. The unit is now in Start-Stop Operation.
In Electric Operation, if battery condition is the only reason the unit needs to operate, the compressor will stop but the battery charger will remain energized.
Start-Stop operation may be configured with setpoint ranges tied to either frozen or perishable loads. Refer to Section 5.2.3 for configuration information.
The START-STOP/CONTINUOUS key is locked out if "START-STOP LOCKED" displays in the MessageCenter when pressed and the unit is in Start-Stop Operation, or "CONTINUOUS LOCKED" displays when pressed and the unit is in Continuous Run Operation.
If the unit fails to start after three start attempts, alarm 00031 FAILED TO START - AUTO MODE will activate.
If the unit shuts down three consecutive times without running a minimum of 15 minutes between shutdowns, alarm 00030 FAILED TO RUN MINIMUM TIME will activate. The shutdown counter clears after the unit has run for 15 minutes.
