7.3 Description of the electrical options
7.3.1 Automatic battery charger
The “trickle charger” charges the battery completely and is
disconnected once the unit starts up.
Besides the output terminals (secondary side) the automatic battery
charger has a trim potentiometer for setting of the output voltage.
By means of an insulated slotted screwdriver or adjusting pin the
output voltage can be set in the range.
The LED on the front indicates that the unit is operational.
Setting:
– Lower output voltage = Counterclockwise rotation
– Higher output voltage = Clockwise rotation
To use the batery charger:
– Provide the X25 connector, located at the side of the power cubicle,
with external power to use the battery charger.
7.3.2 Battery switch
The battery switch is situated inside the sound-insulated bodywork.
It allows to open or to close the electrical connection between the
battery and the engine circuits.
7.3.3 Engine coolant heater
To make sure that the engine can start and accept load immediately,
an external coolant heater (1000 W, 240 V) is provided which
keeps the engine temperature between 38°C and 49°C.
Never turn the battery switch to OFF during
operation.
