GENERAL ALARM
To manage the general alarm, an indicator is tted in the alarm terminal. It can be programmed to come on continu-
ously or for a preset time. It triggers any time a fault is detected by the control unit.
A click on any cursor keys causes the alarm to be silenced.
GENSET AND USER PROTECTIONS
Tripping of an anomaly is shown on the display and can cause the engine to cut out and activates the general alarm.
See the FAULT LIST table on page 17.
Normally the display shows the genset instruments; in the event of an anomaly, it displays the anomaly message trig-
gered. If the anomaly causes a stop, the red LED ashes and the does not cause any stop, the yellow LED ashes
and icon lights up.
If the faults are detected by the CAN Bus line connected to the electronic injection control unit of the engine, the red
and yellow LEDs do not ash, but they stay on with a steady light.
To view the instruments in the display again and to simultaneously silence the general alarm, press one of the
4 arrow keys used to surf the display. Twenty seconds after pressing the key the display shows the triggered
fault(s) again.
The faults are reset as soon as the OFF RESET LED lights up after pressing button .
If the OFF function is disabled, the faults are reset by pressing button .
GENERATOR SET START-UP WITH A LOW CHARGE BATTERY
The function which enables generator set start-up using a low charge battery is only enabled in automatic mode.
When the voltage measured on the battery terminals drops below the min. threshold, the engine gets ignited and
keeps running until the max. threshold is exceeded and the programmable delay has elapsed.
START-UP UPON POWER REQUEST
The function which enables generator set start-up upon power request is only enabled in automatic mode. When the
power absorbed by the user stays above the programmed threshold for the entire intervention delay time, the control
unit starts up the generator set and switches the user to the genset. When the power absorbed by the user stays
below the programmed threshold for the entire intervention delay time, the control unit switches the user to the mains
and stops the generator set.
DAILY START-UP AND STOP
The functions managed by the clock tted in the control unit are only enabled in automatic mode. Up to 10 generator
set start-ups may be programmed, including user switching to the genset at specic daily time slots.
The possibility also exists to program a stop of the generator set in a specic time slot in the day.
CALL INPUT (terminal 30)
The call input is enabled when the control unit is in automatic and test mode. When the contact closes, the
machine operates as if in presence of a mains fault.
RENTAL FUNCTION
This function enables programming of the rental hours of the generator set, after which the control unit either immedi-
ately stops operation of the genset or prevents the next start-up. When programmed,
the stop occurs even if the MANUAL PROTECTIONS are disabled and the DISABLE PROTECTIONS input is ena-
bled. The rental hours decrease as the engine is running.
PREVENTIVE MAINTENANCE
When periodic maintenance is required, the light turns on intermittently and the display shows the number
corresponding to the maintenance operation required, as previously scheduled, with a description. If scheduled, the
stop occurs even if the MANUAL PROTECTIONS control is disabled and the DISABLE PROTECTIONS input is ena-
bled. Resetting of any expired maintenance can only be performed by the generator set manufacturer.

See the FAULT LIST table on page 17.
Normally the display shows the genset instruments; in the event of an anomaly, it displays the anomaly message trig-

stop, the yellow LED ashes and the icon lights up.
Press the ARROW to review the instruments on the display and, at the same time, silence the general alarm, use one of
the 4 navigational arrows. After 20 seconds have elapsed since the last time the key was pressed, the display
reverts back to displaying the anomaly/anomalies that have occurred.
When OFF RESET lights up, the anomalies can be reset by pressing the key .
If the OFF function is disabled, press the key to reset the anomalies.
DAILY STARTING-STOPPING
The functions managed by the control unit’s internal clock are only active in automatic mode. Up to 10 genset starts can
be programmed, with relative switching of the power user to the generator at certain daily time slots.
It is also possible to program a genset lockout at a certain daily time slot.
CALL INPUT (TERMINAL 30)
Call input is active with control unit in automatic and test modes. When the contact closes to ground, operation is the
same as that of a mains failure.
