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 Q1.1 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
