Operating Qc3001 - Atlas Copco QAS 14 Instruction Manual

QAS 14 - 20 Pd
3.4.2 During operation Qc1001™
Following points should be carried out regularly:
– Check the engine gauges and the lamps for normal readings.
!
Avoid to let the engine run out of fuel. If it hap-
pened, priming will speed up the starting.
– Check for leakage of oil, fuel or coolant.
– Avoid long low-load periods (< 30 %). In this case, an output drop
and higher oil consumption of the engine could occur.
– Check, by means of the generator gauges, that the voltage between
the phases is identical and that the rated current in the third phase
(L3) is not exceeded.
– When single-phase loads are connected to the generator output
terminals, keep all loads well-balanced.
If circuit breakers are activated during operation, switch off the
load and stop the generator. Check and, if necessary, decrease the
load.
! The generator's doors may only remain opened for
short periods during operation, to carry out checks
for example.
3.4.3 Stopping Qc1001™
To stop the unit locally, proceed as follows:
– Switch off the load.
– Switch off circuit breaker Q1.
– Let the engine run for about 5 minutes.
– Stop the engine by putting the starter switch in position O.
– Lock the side doors and the door of the indicators and control panel
to avoid unauthorized access.
To stop the unit when the starter switch is in
position , proceed as follows:
– Switch off the load.
– Stop the engine by putting the remote start/stop switch in position
stop or by putting the starter switch in position O.
– Cooldown period default 15 sec.
– Lock the side doors and the door of the indicators and control panel
to avoid unauthorized access.

3.5 Operating Qc3001™

3.5.1 Starting Qc3001™
– Turn the optional battery switch to ON.
– Turn the S20 button to the ON position, this will activate the
Qc3001™ Controller.
– Select the correct application type and the correct mode on the
Qc3001™ module (see Overview of applications for the possible
selections).
– Make the correct wirings and program the applicable parameters
(see Standard applications for more details).
– When in SEMI-AUTO mode, use the START button to start-up the
generator. The GB button cannot be used to close the generator
breaker.
– When in AUTO mode, the generator will start-up automatically and
close the contactors depending on the selected application.
!
The START button, the GB-close button and the
MB-close button cannot be used in AUTO mode.
3.5.2 During operation Qc3001™
Following points should be carried out regularly:
– Check the display for normal readings.
!
Avoid letting the engine run out of fuel. If this hap-
pens, priming will speed up the starting.
– 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
immediatly after any low load operating period.
– When single-phase loads are connected to the generator output
terminals, keep all loads well-balanced.
!
Never turn the optional battery switch to OFF dur-
ing operation.
If circuit breaker Q1 trips off during operation, switch off the load
and stop the generator. Check and, if necessary, decrease the load.
3.5.3 Stopping Qc3001™
– When in SEMI-AUTO mode, use the STOP button to stop the
generator. The GB button will not 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.
!
If you want to stop the generator manually, use the
S20 button or the emergency stop button.
