5 PROTECTIONS AND WARNING SIGNALS
The generators are equipped with a series of protections
which safeguard it against improper use and faults which
may compromise integrity.
5.1 P
ROTECTION
AGAINST
SHORT
-
CIRCUIT
AND
OVERLOAD
See par.2.3 "Table of tecnical characteristics"
For protection against short-circuits and overloads,
the generators have been fitted with magnetothermal
and differential switches which trip, cutting the power,
if there is an overload condition on the alternator or a
short-circuit.
Before restoring the power by returning the
magnetothermal switch lever to the ON position remove
the cause of the fault.
A main differential magnetothermal switch cuts the
power to all the outlets in the event of a short-circuit,
overload and current leakage to earth.
5.2 E
NGINE
PROTECTION
In the case that occur an insufficient pressure of the oil
engine, the generator set turn off automatically.
Fill the quantity of lacking oil to be able to restart the
generator set.
The low oil pressure protection does not give an
indication of the oil level. The oil level must
periodically be checked in order to prevent
damage to the engine.
The sum of absorption of all the
utilities connected to the generator must never exceed
the continuous power value of the generator.
4.6 S
TOPPING
The generator is stopped by turning the ignition key
completely anticlockwise to the STOP position.
Before stopping it, it is recommended to run it for a few
minutes without applied load so that the internal
temperatures of the engine and alternator are gradually
reduced.
4.7 E
MERGENCY
STOP
For an emergency stop of the generator press the
"mushroom-head" emergency stop button.
Having removed the causes that determined the need for
an emergency stop, release the emergency stop button
in order to return to the operating conditions.
