Unit Operation

Operating Principle
After starting up the refrigeration unit by pressing the ON key on the
Cab Command Two Controller, unit start -up and shutdown are
automatic.
• On Road operation: An open-type compressor is driven
by the vehicle's engine. The vehicle battery powers the
evaporator and condenser fans. The unit automatically
shuts down when the engine is switched off with the
ignition key.
• On Standby operation: A standby compressor is
energized, and a transformer is used to power the
evaporator and condenser fans. The power connection
is detected by the controller, which automatically starts
up in the unit in Standby mode.
•
If the ignition key is switched on while the unit is
connected to power or the unit is connected to standby
power while the engine is operating, the controller
triggers a visual alarm in the form of a flashing red
malfunction light and readout.
•
In all cases, the unit can be completely shut down
manually by pressing the OFF key on the Cab
Command Two Controller.
