The table below summarises the relation between the position
of the potentiometers and the value of the timers.

The timers are factory set at position 0.
Engine cooling water heater
To make sure that the engine can start and accept load
immediately, an external cooling water heater (1000W, 240V)
is provided which keeps the engine temperature between
38°C and 49°C.
Automatic battery charger
The “trickle charger” charges the battery completely and is
disconnected once the unit starts up.
To prolong the lifespan of the batteries, the battery
continuously discharges via the lock-out switch of the battery
charger and a small resistor.
When the unit is shut down for a longer period or will be
stored, make sure to switch off the lock-out switch of the
battery charger to prevent the battery from discharging
completely.
Connection block for monitoring
X25 ...Connection block
Allows easy connection for sensing of mains voltage and
control of the mains and the plant contactor.
Refer to circuit diagram of the “Automatic mains failure” option
for the correct connection.
