GB
5. OPERATION
5.1. START THE UNIT
Power source selection is fully automatic. This is why there
is no button to select the desired mode. A soon as one op-
erating mode is disabled, the unit automatically starts up in
the other mode.
If the vehicle's ignition is switched on while the PULSOR
®
unit is connected to the mains ("Standby" mode) or if the pow-
er plug is connected while the vehicle's engine is running
("Road" mode), the cab command unit will trigger a visual
alarm, in the form of a flashing red malfunction indicator light
and a A035 code.
As soon as one operating mode is disabled, the unit auto-
matically starts up in the other mode and returns to normal
functioning.
5.1.1. "ROAD" MODE
1. Switch on the vehicle's ignition.
2. Press the ON key to start the unit.*
After a prolonged shutdown in cold weather, the
compressor needs to warm up.
During this sequence, the unit displays "CPHT" for 3 to
12 minutes (the duration varies according to the ambient
temperature).
DO NOT SWITCH OFF while "CPHT" is displayed.
3. The setpoint will be highlighted for 5 seconds, followed by the
actual box temperature.
* Once you have started the unit at the beginning of your
drive, the following start and stop sequences are performed
automatically by the vehicle's ignition system.
5.1.2. "STANDBY" MODE
For safe & reliable operation in "Standby" mode, it is important
to consider the following guidelines:
A. ALWAYS check that the unit is OFF from the cab command
before connecting or disconnecting it from the mains.
B. The unit connection cable must be fitted with a ground
connection. The cable must be connected to earth.
C. On the 230V / 400V power supply, the unit must be connected
to a high sensitivity differential protection (30 mA).
D. Operations on the 230V / 400V power supply to the unit must
only be carried out by authorized personnel.
