The microprocessor controller will run a self test. All of the mode
lights will light, all of the segments on the display will be turned on.
The display will then show the setpoint temperature on the left and
the box temperature of the trailer on the right. The last character
(after the degree symbol) shows the temperature units as F
(Fahrenheit) or C (Celsius).
If the unit is in Auto Start/Stop mode or Continuous Run/Auto
Operation mode, the glow plugs will energize, the buzzer will
sound, and the diesel engine will start.
If the unit is set for Continuous Run/Manual Operation mode, the
unit must be started manually.
WARNING
Under no circumstances should ether or any other
starting aids be used to start engine.
The microprocessor controller monitors box temperature, battery
voltage, and engine coolant temperature. Once the setpoint is
reached the controller will shut off the diesel engine to conserve
fuel. The controller will not shut off the engine if the battery voltage
is not sufficient to restart it.
The controller will restart the engine if any of the following criteria
have been met:
SBox 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.
SBox temperature has moved away from setpoint by ¦3.6°F
(2.0°C) AFTER minimum off time for setpoints in the perishable
range or +3.6°F(2.0°C) for setpoints in the frozen range.
SThe battery voltage drops below 11 Vdc (12.2 Vdc for units with
EEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).
SThe engine coolant temperature drops below 34°F(1°C).
