Programming mode is used to adjust delays, operating
limits and configuration of the unit.
In order to enter the program mode please hold
pressed the MENU button for 10 seconds.
In program mode, when the MENU pushbutton is
depressed, the display shows the program number.
When MENU pushbuttopn is released the program
parameter value is displayed.
Entering the program mode does not affect genset
operation. If mains fail during programming, then the
genset will automatically run and take the load.
Program parameters may be scrolled with MENU
button. If the pushbutton is held pressed then the
parameter number increases faster.

Following parameters are in the "high priority" group.
Parameter value is increased/decreased with RUN
(▼) and AUTO(▲) pushbuttons. If the pushbutton is
held pressed then the parameter value
increases/decreases faster.
When the program parameter is modified, it is
automatically saved in a non-volatile memory.
In order to exit program mode, press the STOP button.
If no button is pressed during 1 minute, the unit will
automatically exit the program mode.
Program parameters are divided in two groups being
low and high priority parameters. If the program mode is
entered by pressing the MENU button, only low priority
parameters are displayed. In order to display high
priority parameters, enter the program mode by holding
pressed both MENU and STOP buttons.

All transformers must have the same rating.
The secondary of the transformer will be 5 Amps.

If the current goes above this limit, during the period
defined in Overload Timeout then a Overcurrent Load
0
Dump alarm will be generated.
If this parameter is 0 then Overcurrent check is disabled.
If the active power goes above this limit, during the
period defined in Overload Timeout then an Excess
0
Power Load Dump alarm will be generated.
If this parameter is 0 then Excess Power check is
disabled.
This is the period between OVERCURRENT or EXCESS
POWER or VOLTAGE or FREQUENCY limits are
5
exceeded and the related alarm occurs.
This is the time after the fuel solenoid is energized and
1
before the genset is started. During this period the
PREHEAT relay function is active.
This is the control delay of CHOKE output.
The choke output is activated together with the crank
5
output. It is released after this delay or when engine
runs, whichever occurs first.
This is the period used for engine heating before
4
genset takes the load.
This is the maximum time duration for the engine to
stop. During this period the STOP relay function is
10
active. If the genset has not stopped after this period, a
FAIL TO STOP warning occurs.
This is the time between the mains voltages entered
0.5
within the limits and the generator contactor is
deactivated.
This is the period that the generator runs for cooling
1.0
purpose after the load is transferred to mains.
If one of the mains phases goes under this limit, it
170
means that the mains are off and it starts the transfer
to the genset in AUTO mode.
If one of the mains phases goes over this limit, it
270
means that the mains are off and it starts the transfer
to the genset in AUTO mode.
