GENERATORS
In addition, the automatic control panel maintains the
charge in the generator start-up battery, even when the
generator is off.
The unit is hooked up to the automatic control panel
through the 6-pin connector found on the unit instrument
panel (fig. 4 ref. 14) and a power supply plug inserted in the
outlet located on the generator instrument panel (fig. 4 ref.
11).
ATTENTION
When the generator is connected to the automatic
control panel the ignition key located in the instru-
ment panel must remain in the OFF position.
The automatic control panel has the following parts:
- a function selector (MANUAL, AUTOMATIC, BLOCK,
TEST);
- four warning lights indicating the status of the contac-
tors;
- four operating warning lights and alarms;
- two buttons, one for start up and one for shut down.
Automatic operation
If the function selector is in the AUT position, the auto-
matic control panel will start up the unit whenever the line
voltage cuts out. If the unit is not on, the panel will make
a maximum of 4 attempts to turn it on. If these prove
unsuccessful, a warning light will go on indicating that
start up has failed.
ATTENTION
Before setting the AUT function, it is essential to press
the STOP button located on the automatic control
panel or set the BLOCK function for a few instants.
This operation is required because, after the auto-
matic control panel has been operating in MANUAL
for 10 seconds, if the start-up is not performed by
pressing the START button, the protections will cut in
preventing start up.
Manual operation (hand)
This function makes it possible to start up the generator
manually whether there is voltage from the mains or not.
This is done using the START button located on the
automatic control panel. If the mains are powered, the
equipment will, in any case, be powered from the mains
even when the generator is on.
When Manual function has been selected and the genera-
tor is on, should the line power cut out, the automatic
control panel will switch the power supply line so that the
equipment is powered by the generator.
Test function
Setting the unit to this function, the automatic control
panel will perform an automatic start-up cycle in order to
check generator function. It is advisable to perform this
test at least once a week.
UK
Block function (padlock)
Selecting this function prevents the generator from being
started up by the automatic control panel.
DANGER
Select this function whenever maintenance or repairs
are being performed on the unit. This will prevent the
generator from being accidentally started up in case
the line power cuts out.
5 PROTECTIONS
The units are equipped with a series of protections to
safeguard them from improper use and from failures which
could compromise their function. These protect against:
- Low oil pressure
This cuts in, turning off the unit, whenever there is
inadequate pressure in the lubrication circuit; when it cuts
in a LED (fig. 4 ref. 16) goes on.
In this case, adding additional oil is usually enough to start
up the unit once more.
ATTENTION
The low oil pressure protection does not provide any
indication as to the oil level. To prevent damaging the
engine, it is essential to check the oil level periodi-
cally.
- High engine temperature
This protection cuts in, turning off the unit whenever the
engine operating temperature is too high. When activated
a LED (fig. 4 ref. 19) goes on.
In this case, the unit can only be started up again after the
cause has been identified and eliminated.
- Short circuits and overloads
To protect against short circuits and overloads, the unit is
equipped with magnetothermic and differential breakers
which cut off the power supply when the alternator is
overloaded or there is a short circuit.
Before powering the unit again by flipping the magneto-
thermic breaker levers (fig. 4 ref. 8-9) back to the ON
position, the problem which caused it to trip must be
removed.
For this purpose the following breakers are used:
- the general differential magnetothermic circuit breaker:
in the case of short circuit, overload and current leakage
to ground, this cuts off the power supply to all outlets (fig.
4 ref. 8).
