2. Verify that "START-STOP MODE SELECTED" is displayed on the MessageCenter and that the START-
STOP light is illuminated. The unit is now in Start-Stop operation.
Start-Stop is provided to reduce fuel or power consump-
tion. This feature allows full automatic control of the unit
shutdown and restart by monitoring refrigerated com-
partment temperature, battery charging amps and en-
gine coolant temperature (Engine Operation only). The
main function of Start-Stop Operation is to turn off the
refrigeration system near setpoint to provide an efficient
temperature control system and to initiate a restart se-
quence after certain conditions are met. The Start-Stop/
Continuous key is pressed to select between Continu-
ous Run and Start-Stop Operation. The corresponding
LED will be iluminated.
The microprocessor may be configured with Start-Stop
operation tied to the set point ranges for frozen and per-
ishable loads. The Start-Stop/Continuous key is locked
out if "START-STOP LOCKED" displays in the Messa-
geCenter when the key is pressed and the unit is in
Start-Stop Operation or "CONTINUOUS LOCKED" dis-
plays in the MessageCenter when the key is pressed
and the unit is in Continuous Run Operation. Refer to
Section 5.2.1 for Configuration information.

If the unit fails to start after three start attempts, the A31
- "FAILED TO START-AUTO" alarm will be activated.
While running, if the unit shuts down, an internal counter
keeps track of the shutdowns. Should the unit shutdown
three consecutive times without running a minimum of
15 minutes between shutdowns, the A30 - "FAILED TO
RUN MINIMUM TIME" alarm will be activated. The shut-
down counter is cleared when the unit has run for 15 mi-
nutes.
In Standby Operation, the unit will stop for a
minimum of 5 minutes instead of 15 minutes.
Refer to Section 4.4 for more detailed information on
Start-Stop Operation.
