During operation Qc4002™
Following points should be carried out regularly:
– Check the display for normal readings.
– Check for leakage of oil, fuel or cooling water.
– Avoid long low-load periods (< 30%). In this case,
an output power drop and higher oil consumption
of the engine could occur. It is recommended to
operate the generator at full load capacity
immediately after any low load operating period.
– When single-phase loads are connected to the
generator output terminals, keep all loads well-
balanced.
If circuit breaker Q1 trips off during operation, switch
off the load and stop the generator. Check and, if
necessary, decrease the load.
The generator’s side doors may only remain opened
for short periods during operation, to carry out checks
for example.
Stopping Qc4002™
– When in SEMI-AUTO mode, use the STOP
button to stop the generator. The GB button will
work to open the GB.
– When in AUTO mode, the STOP and GB button
will not function. The generator shuts down
automatically depending on the selected
application
.
The START button, the GB-close
button and the MB-close button
cannot be used in AUTO mode.
Avoid letting the engine run out of
fuel. If this happens, priming will
speed up the starting.
Never turn the optional battery
switch to OFF during operation.
If you want to stop the generator
manually, use the S20 button or the
emergency stop button.
