The operational modes that can be selected with the programming switch are six, namely:

1. Automatic test: This starts to test the generator without disconnecting the mains power supply from the

utility. When the switch is turned back to automatic mode the generator stops following a delay of roughly

one minute

(it is used for periodic tests or to check the running efficiency after the maintenance).

2. Automatic mode; if there should be a failure in the mains the circuit board responds by opening the

mains contact maker. If the generator fails to start another 4 starting attempts are made. 10 seconds

after the start the generator powers the utility. While running the generator and motor are constantly

controlled and a possible anomaly is immediately displayed (examples: fuel reserve, water level,

overload, min. voltage etc.) and the relative stopping cycle is triggered. Once the mains is re-connected,

after the set time, the utility is switched back to the mains and the generator is stopped following a delay

of roughly one minute to allow it to cool down

3. Lock: this sets the generator in a locked status. It disables every possibility of starting while the mains

power the utility. This mode is used to work on the system safely, being certain that the generator will not

start even if the mains should be disconnected

4. Manual mains: it permits having the forced power supplied from the mains in case of command and

control electronics breakdowns as well

Manual starting: this allows the manual start of the generator using the start push button. The control is

direct without the involvement of electronic components. It ensures the operation of the generator even

when the electronics are faulty

purposes).

When the programming switch is in this position, all the utility circuits of the generator, such as the

solenoid valves, electronic rpm regulators etc, are powered . In case the switch is left by mistake in this

position with the generator stopped, the starting battery would run flat very quickly.

Manual generator: it permits the forced power to be supplied from the generator

manual operations or in the case of automatic functions breakdown).

STOP

This is always enabled in every situation.

The button has to be pressed till the motor stop
