I
Note: Please consider the following proposed settings as guidelines only as the
final settings should be performed after measuring the flue gas (C02/02
content). The local control panel settings and cam switch settings depend
on
burner
size, nozzle size, furnace pressure, etc.
Step
E:
Pre-adjust the stand-by position (burner stopped) to 0% (0°) on the control
panel.
Step F: Pre-adjust the ignition position to 22% (20°) on the control panel.
Step G: Pre-adjust the minimum firing position (partial load) to 33% (30°) on the
control panel.
Step H: Pre-adjust the purge and full load position to 67% (60°) on the control panel.
1.2.5 Assembling
Step
A:
Mount the cover for the servo motors.
Step B: Close the burner and secure with
the.
screw.
Step C: Switch on power and reset the control system.
1.3 Commissioning
of
the oil system
When the oil system is commissioned, it should initially be flushed by means
of
an
external pumping system. This must be done to ensure that the oil system is not clog-
ged-up and to prevent foreign objects from entering the pump unit which might cause
damage.
Warning: When the oil system
is
commissioned
on
diesel oil, the tracing
of
the
piping system must be off.
Step
A:
Check that oil
is
present in the diesel oil tank. Open the stop valves, which
connect the diesel oil tank to the oil system.
Step B:· Select diesel oil on the manually operated three-way valve. Check that the
control system indicates diesel oil operation.
Step C: Open the inlet stop valves, and the outlet non-return valves for the oil pumps.
Step
D:
Open the stop valves for the pressure gauges on the oil pumps.
Note: The stop valves for the pressure gauges
on
the pump unit should only be
opened for pressure control purposes. The stop valves should be closed
during normal operation.
Step E:
Open the stop valve for the pressure transmitter and/or switches.
Step F: Close the quick closing valves for the burner unit. Check that the micro
switch
is
activated and that a shut down appears
in
the control system.
Step G: Rotate the oil pump by hand to ensure a free and an uninterrupted rotation.
Step H: Adjust the circuit break for the pump to suit full load current
of
the motor.
The current appears from the motor identification plate and/or the electric
diagrams.
