Operation
ESC function (Engine Smart Control) (09)
■
When starting the engine with the ESC
switch in position "ON" and no consumers
connected to the generator:
■
At an ambient temperature below 0°C, al-
low the engine to warm up at rated speed
(5000 rpm) for 5 minutes.
■
At an ambient temperature below 5°C, al-
low the engine to warm up at rated speed
(5000 rpm) for 3 minutes.
■
After this time, the ESC function regu-
lates the engine speed to the required
operating speed depending on the num-
ber of connected appliances and the as-
sociated load.
■
If the ESC switch is turned to "OFF", the en-
gine runs at rated speed (5000 rpm) irrespec-
tive of whether or not any electrical applianc-
es are connected.
■
The ESC switch must be turned to OFF if
electrical appliances are connected that
require a high starting current (e.g. com-
pressor or immersion pump).

Warning and indicator lights (13)
5.2.1
Oil warning light – red (13/1)
If the oil level drops below "Minimum" the oil
warning light comes on and the engine stops au-
tomatically. The oil must be topped up before the
engine can be started again.
5.2.2
Overload indicator light – red (13/2)
The overload indicator light comes on if the gen-
erator is overloaded by a connected electrical ap-
pliance, the inverter control unit overheats, or the
AC output voltage increases. Power generation is
stopped to protect the generator and all connect-
ed electrical appliances. The green alternating
current (AC) indicator light (13/3) is no longer lit.
The engine continues to run.
1. Switch off all connected electrical appliances.
2. Switching off the engine
3. Reduce the total power of the connected
electric appliances to below the maximum
rated output power of the generator (i.e. dis-
connect appliances).
4. Check the ventilation grille and operating
panel for soiling and clean, if necessary.
5. After checking, start the engine again.

NOTE When using electrical appliances that
require a high starting current (e.g. compressor
or immersion pump), the overload indicator light
may come on briefly. That is not a malfunction.
5.2.3
Alternating current (AC) indicator light
– green (13/3)
The AC indicator light comes on if the engine is
running and power is being generated.
5.3
Direct current (DC) safety switch (14)
The DC safety switch automatically switches to
OFF when the electric power of the connected
appliances exceeds the operating current. To use
the generator again, press the DC safety switch
to switch it to ON.
■
If the DC safety switch switches to OFF, re-
duce the total power of the connected appli-
ances to below the maximum rated output of
the generator (i.e. disconnect appliances).
■
Please contact the manufacturer's service
centre if the DC safety switch constantly
switches to "OFF".
5.4
Connecting an appliance
The total power of all connected electric applianc-
es must not exceed the maximum rated power of
the generator.
1. Check whether the AC indicator light is lit.
2. Connect the appliance to the socket of the
generator.
If several appliances are to be connected, first
plug in and switch on one appliance, then plug in
and switch on the next appliance.
5.5
Unplugging appliance
1. Unplug the appliance from the socket of the
generator.
5.6
Connecting a 12 V car battery for
charging
WARNING! Risk of fire and explosion
when charging. An incorrectly connected car
battery can explode and cause serious injuries.
■
Do not reverse the charging cables when
connecting to the car battery.
■
Observe the manufacturer's instructions on
charging the car battery.
1. Start the engine.
2. Connect the battery charging cable to the
12 V DC output.
