4.2. LOCK/UNLOCK CAB COMMAND

The lock function allows to block any manipulations from the Cab
Command.
The user can only start and stop the unit.
1. To lock or unlock the cab command, hold together the ENTER & UNIT
DATA keys for 5 seconds.
"DSP LOCK" is displayed for 10 seconds, when locking.
"DSP UNLCK" is displayed for 10 seconds, when unlocking.

4.3. START A PRETRIP

The PRETRIP is a test sequence to check unit operation. When
PRETRIP is enabled, the unit will enter a test sequence to operate
the unit in various operating modes
If a failure occurs during PRETRIP, the microprocessor will gen-
erate an alarm.
This function can operate in Road or Standby mode
This is not a self-diagnosing PRETRIP test. No specific PRETRIP
alarms will be generated. PRETRIP must be monitored by the user
to verify that the unit operates through all cycles.
The PRETRIP can only be initiated if the following condition is
reached: DTS < 4°C.
1. Press the FUNCTION key until "PRETRIP" is displayed.
2. Press the ENTER key.
The "PRETRIP N" should be flashing, indicating that it can be set.
3. Press either of the ARROW key until "PRETRIP Y" is displayed.
4. Press the ENTER key to start the PRETRIP.
The PRETRIP starts and its status ("TEST X/Y"*) is displayed.
X = current test number.
Y = total number of tests to be performed.
To abort a PRETRIP in progress, hold the ENTER key during 5
seconds.

the required time (depending on the engine temperature) and
then starts automatically.

4.5. STARTING THE UNIT - STANDBY OPERATION

4.5.1. INTRODUCTION

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 power source.
B. The unit connection cable must be fitted with a ground connection.
The cable must be connected to earth.
C. On the 400 V supply, the unit MUST BE CONNECTED to a high
sensibility (30 mA) differential protection.
D. Operations on the 400 V supply for the unit must only be carried out
by authorized personnel.
E. The user is liable for ensuring that the above measures are taken.
Changing the operation of a unit from 400 V to 230 V implies a
change in the electrical coupling, and for certain unit models, the
replacement of some components.
Please consult our technical service.
