4.3 Operating and setting
Qc2002™
4.3.1 Starting
To start up the unit locally, proceed as follows:
– Switch on the battery switch.
– Switch off circuit breaker Q1. This is not
necessary when a plant contactor is installed
between Q1 and the load.
– Put the starter switch S20 in position I (ON).
Voltage is applied to the Qc2002™ module.
– The unit can be started manually by pressing the
START button on the Qc2002™ module.
– The unit will start.
In cold conditions the unit might not start from the
first attempt. The controller will take 3 start
attempts.
– Switch on circuit breaker Q1 in case no contactor
is installed.
To start up the unit from a remote location,
proceed as follows:
– Put the starter switch S20 in position I (ON).
Voltage is applied to the Qc2002™ module.
– Switch on circuit breaker Q1.
– For remote start:
• Put the unit in Island mode. Push the
AUTOMATIC button. Use an external switch
to start the machine.
or
• Put the unit in AMF mode. Push the
AUTOMATIC button. The machine will start
automatically when Mains fails.
See also ‘Genset mode’ on page 41 for more
detailed information on Island and AMF mode.
– The unit will start.
In cold conditions the unit might not start from the
first attempt. The controller will take 3 start
attempts.
4.3.2 During operation
Regularly carry out following checks:
– Check the analogue meters (P1-P4) and the
controller display for normal readings.
– Check for leakage of oil, fuel or coolant.
– Check, by means of the generator gauges, that the
voltage between the phases is identical and that
the rated current is not exceeded.
– When single-phase loads are connected to the
generator output terminals, keep all loads well-
balanced.
– If circuit breakers have tripped during operation,
switch off the load and stop the generator. Check
and, if necessary, decrease the load.
Avoid to let the engine run out of
fuel. If it happened, priming will
speed up the starting.
Avoid long low-load periods
(< 30%). In this case, an output
drop and higher oil consumption of
the engine could occur. Refer to
‘Preventing low loads’.
The generator’s doors may only
remain opened for short periods
during operation, to carry out
checks for example.
