OPERATION
GENERATOR SET STARTING WITH LOW BATTERY CHARGE
(with control unit in automatic mode)
STARTS OR STOPS the generator set depending on the voltage measured on the battery terminals
Before starting automatically, the generator set activates the intermittent general alarm for 8 seconds, followed by a
pause of 3 seconds.
12.
When the voltage measured on the battery is lower than the minimum threshold, THE ENGINE STARTS.
When the voltage exceeds the maximum threshold after the intervention delay, THE ENGINE STOPS. To change the
programming of the thresholds and of the delay see the basic table of the TECHNICAL
PROGRAMMING
OPERATIONS manual on page
The intervention of the fault is displayed; it can cause the engine to be stopped and activates the general alarm see
BASIC TABLE at pages 10-11 of the TECHNICAL PROGRAMMING manual.
When the engine is running the generator set instruments are shown.
When there is a fault, instead of the reading, the display shows the intervened fault message, and the associated
yellow LED flashes.
FAULT DISPLAY
FAULT RESET
It is possible to access the reading of the measurements and at the same time to silencing the general alarm,
by pressing key for 1 second.
The display will resume showing the previous fault 20 seconds after the last pressing of the key.
On pressing the key , the protection devices and all the locked functions are reactivated.

GENERATOR SET PROTECTION DEVICES AND USER
GENERAL ALARM
This is produced by mounting an acoustic signal, linked to the appropriate terminal
It can be arranged so that it is activated continually or for a set time
When key is pressed the general alarm is silenced.

PREVENTIVE MAINTENANCE
When preventive maintenance operations need to be carried out, the yellow LED flashes while the number of
the intervened maintenance appears
The timing for the maintenance operations and the procedure for zeroing the time up maintenance indication can be
programmed by the manufacturer of the generator set unit
.
.
EMERGENCY STOP
The emergency stop can be activated in all working conditions, by mounting one or more click down push-button.
The stop is immediate (without engine cooling), does enable the general alarm and EMERGENCY STOP is shown
on the display.
STOPPING FAILED
This intervenes if the running engine signal is detected 120 seconds after the stop command.
STOPPING FAILURE will be read on the display.
Do not use the emergency button combined with a stopping system
that is not energized in run mode
.
DETECTION OF RUNNING ENGINE
It is obtained by detecting generator frequency and residual voltage or by detecting battery charger alternator
(permanent magnets or pre-excitation) voltage and frequency. It is also possible to use a pick-up device in place of
the alternator. In case of engine equipped with electronic injection controller (CAN Bus) it is not necessary any pick-
up and the alternator is used only to detect belt breakage.
When the running engine signal has been detected the unit disconnects the starter and switches on the led

STOP
This starts or stops the generator set according to the power detected by the control unit.
A general alarm triggers for 8 seconds followed by a 3-second pause before automatic start-up of the generator set.
As soon as the power value of the power user is above the programmed threshold during the entire engagement
delay, the control unit starts the generator set and controls opening of the network contactor.
With engine running the generator contactor closes when the generator voltage is regular and the generator
engagement delay to the power user has elapsed.
As soon as the power value of the power user is below the programmed threshold during the entire engagement
delay, the control unit opens the generator contactor, after the generator mains interlock time the mains contactor
closes. The cooling time allows for and facilitates cooling of the engine before it is stopped.
