If the engine is equipped with a water heater, will need to be in Auto mode for the water heater to operate. The water heater can be stop-
ped in two ways:
- via the thermostat mounted on the engine
- via the fuel stop solenoid when energised.
A message appears on the screen opposite when the water heater is activated. This message is dis-
played alternately with message ext ccommand=0.
As soon as the generating set starts, the message water hheater will no longer appear.

Some engines are equipped with an air intake heating glow plug enabling easier start-up in cold weather. As factory programming was car-
ried out, the engine preglow output will be activated at the beginning of any start-up sequence (see screen 1). This preglow period can be
adjusted (factory programmed). Engine preglow is also active between two start-up attempts. However, the operating time is equal to the
interval between two attempts (see screen 2).

The fuel solenoid control activation is interlocked with the engine preglow control or starter control activation. The fuel solenoid supply is
then permanent. It is interrupted when the engine shutdown is requested (Stop button pressed, normal shutdown in Auto mode, emergency
stop pressed, shutdown on any fault).

In cases where the user installs a differential protection relay or a constant insulation checking device different from those offered, will not
be able to display the feedback data from these various relays. Therefore, access to Protect menu will not be possible.
- The delay setting can be displayed between 0 and 10 seconds, with:
- a display in milliseconds between 0 and 100ms
- a display in seconds above 100ms
- The fault current percentage displayed varies according to the relay initial setting.
Example: relay set to 300mA, fault current=150mA, the screen display will be of 50%.

The " Isom AS " type relay will do this function. Protection via permanent insulation check is used in IT neutral systems (impedant or insula-
ted neutral). When the cursor flashes over the o sign next to Protect, the CONSTANT IINSUL C
CHECK screen below is displayed.
Insulation RResistor indicates the real time insulation level in the circuit.
