GENERATOR (OPTION)
The built-in generator is driven by a multi V-belt
drive. The generated current can be drawn via 3
sockets (see chapter Technical specifications). The
generator is also equipped with an automatic control
system to save fuel when no electric power is used.
The compressor and the generator may be used
simultaneously.
Generator operation
Start the unit in accordance with the normal
procedure. Let the motor warm up until it reaches
operational temperature. Turn the generator switch
(3) to position “1”. The normal control system is
switched off and the motor speed increases to reach
the maximum. The green lamp in the switch is
activated, showing that sockets are live.
Using switch (2) you can switch on the automatic
control system. As soon as the generator is switched
on, the automatic control system will continuously
check for electric load in order to rev up the engine
from idle to nominal speed only when needed. This
saves fuel and reduces emissions. If a consumer is
disconnected, the engine goes on for 60 second before
falling back to idle speed.
With the current continuously monitored, a consumer
having just been switched on is temporary
disconnected from the generator to be re-connected as
soon as the engine reaches nominal speed. This safety
mechanism prevents load at too low speed.
Turning the generator switch (3) to position “0” cuts
off the power from the sockets. The lamp in the
switch is off.
Faults
In case of an overload or an earth fault the circuit
breakers or earth fault relay will trip and the power to
the sockets is turned off.
When this occurs, first disconnect the consumers
from the sockets and manually reset the circuit
breakers / earth fault relay in the electronic box.
Do not use the consumers connected previously
before the cause of the fault is cleared.

4 Terminal earth cable
Before switching on the generator,
always place the earth pin in position.
Check the cable connection between
earth pin and the GND-terminal on the
unit.
Avoid high inductive loads (e.g.
welding). High inductive loads can
damage the generator.
