1- 5 Operation modes
At the power on, the Genset is in reset mode. With the buttons you can choose the functioning mode you prefer.
1- 5.1 Automatic mode
Push the AUT button to select this functioning mode.
In case of mains failure the remote start output (J5.4) is activated and is de-activated in the presence of the same. This is the standard logic. It’s
also possible to activate the remote start output in special conditions. For more information see the special functions menu M6.
1- 5.2 Manual mode
In this operative mode, to turn-on the generator (activating the remote start output) you must press KG button. With engine running, you can
manually command the transfer switching with KG and KR buttons. KR, besides transferring the load on mains side, turns off the generator.
Pressing and releasing quickly the KR button, KG is opened and the remote start output is deactivated after the cooling time; keeping pressed for 3
seconds KR button, KG is opened and the generator is stopped immediately.
1- 5.3 Reset mode
The remote start output cannot be activated. If the mains is available it is connected to the load. If you select Reset mode, the alarms are reset and
the remote start output is deactivated. If the cause of the alarm remains, the cause is still present. Push the RESET button to select this functioning
mode.
1- 5.4 Test mode
Manual test: Press the TEST button: the remote start output is activated to test the genset for a programmable time.
a) If activated during MAN mode, the load switching can be controlled only by KG and KR buttons, even if the mains is faulty. Disabling the test (or
after the test time), the controller returns to the previous operation mode.
b) If activated during the AUT mode, the test can be made with or without load, depending on the programming of the test setup (see menu M4.3).
Automatic test: If you programmed an automatic test (see menu M4.3), it will run only if you are in automatic mode. The test can be made with or
without load, depending on the programming of the test setup (see menu M4.3).
1- 5.5 Alarms
In case of alarm, the display shows its description. If more different alarms are detected, they appear individually in sequence. For each alarm it is
available a message that can help to identify the source of the problem. The alarm reset can be made by pressing the RESET button; by this, the
alarm is deleted and the genset goes in Reset mode, preventing accidental generator starting attempts. If the alarm, after reset, still remains on the
display, the cause of the alarm is not removed.

H Mains OK
It is the delay time after which, if the mains returns within the limits set
(see parameters B, C, E, F), it’s considered stable and the mains
contactor is closed, then begins the stop phase of the generator (in
automatic mode).
0-600 [s] 10
I Faulty mains
It is the delay time after which the mains is considered faulty, compared
with the limits specified in parameters B, C, E, F. This parameter is
used to filter any temporary instability of the mains. Increase this
parameter to avoid fast start/stop procedures due to mains flickering.

K V Asymmetry If the difference between the lower and the higher phase voltages is
greater than this parameter, the asymmetry alarm (if enabled) is shown. 0-100 [%] 10
L KR protection
Parameter to enable the protection on mains failure. If On, the alarms
about the mains immediately open the mains contactor. If Off, the
mains contactor is opened only when the generator is ready.

M System type You can set the type of system of the mains: three-phase, single-phase
or two-phase with neutral.

N Cost for MWh Set the cost for every Mega Watt per hour supplied by mains 1-999999 210
O Start by KR
If On, if parameter “KR protection” is set to ON, every condition which
activates KR protection (phase inversion, feedback KR, asymmetry
alarm, etc...) also triggers an engine start with changeover on generator
until the mains returns ok.

A ON alarm delay
It is the time delay from the engine running detection to the enable of the
alarms; this time allows the generator to reach the nominal operating
conditions.
0-1000 [s] 8
B Cooling time
It sets the cooling time after which the engine is stopped: after the
generator contactor opening, the remote start output remains active for the
set time, to cool down without load. It works only in automatic mode.
0-255 [s] 1
C Siren time It is the duration time of the acoustic advisor in case of alarm, if a
programmable output is set for “Siren”. 0-1000 [s] 20
NOTES:
To avoid any incompatibility between the timings of the ATS and the controller for engine protection, remember that the “ON alarm
delay” must be at least 5 seconds higher than the preheat time in the engine protection controller.
The cooling procedure is managed by the ATS. If the engine protection controller allows to set a cooling procedure, we advise to disable
it and maintain active only the procedure on the ATS controller.
