8. Start/Stop Operation (continued)
The controller will not shut off the engine if the battery voltage is not
sufficient to restart it. Battery voltage above approximately 13.4 volts is
required for shutdown. This varies depending on ambient. The control
system will calculate the equivalent voltage based on ambient.
The controller will restart the engine if any of the following criteria have
been met:
• Box temperature has changed by the selected override tempera-
ture DURING minimum off time
• Box temperature has moved away from setpoint by selected restart
temperature AFTER minimum off time
• The battery voltage drops below 12.2 VDC (Refer to Unit Data sec-
tion) or the selected voltage in configurations
• The engine coolant temperature drops below 34°F (1°C)
Auto Start-Stop operation may be tied to the setpoint ranges
for frozen and perishable loads and the Auto Start/Stop -
Continuous key may be locked out.
