Whenever the unit starts in Auto-Start/Stop, it will run until:
• It has run for the predetermined minimum run time.
• The engine coolant temperature is above 122°F (50°C)
• The box temperature is at setpoint.
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. Look at battery
voltage in data list to find out whether shutdown voltage has been
reached. If there is a “+” in front of the number, the voltage is enough to
shutdown and restart. If only the number appears, the voltage is still too
low for shutdown.
The controller will restart the engine if any of the following criteria have
been met:
• Box temperature has changed by ± 11°F (± 6.1°C) for setpoints in
the perishable range and +11°F (+6.1°C) for setpoints in the frozen
range DURING minimum off time.
• Box temperature has moved away from setpoint by ± 3.6°F (2.0°C)
AFTER minimum off time for setpoints in the perishable range or
+0.5°F (0.3°C) for setpoints in the frozen range.
• The battery voltage drops below 12.2 VDC. (Refer to Unit Data
section).
• The engine coolant temperature drops below 34°F (1°C).
To start the unit in manual start mode, the unit must be in Continuous Run
mode and the Auto/Manual Start Operation function parameter set to
“MAN OP” (FN10 OFF).
When configuration CNF11 is “ON” and setpoint is 32 to 42°F
(0 to 5.5°C) the unit is locked into Continuous Run. The
AUTO-START/STOP key is disabled.
Auto Start-Stop operation may be tied to the setpoint ranges
for frozen and perishable loads and the AUTO-START/STOP
key may be locked out.
