Start-up, calibration and operation of the burner
5.7 Burner start-up
Feed electricity to the burner via the disconnecting switch on the
boiler panel.
Close the thermostats/pressure switches, set the parameters on
the RWF 40 regulator.
Please refer to the spacific manual for this operation.
➤ Turn the switch to position “ ON” (Fig. 30) and turn the switch
of to position “ LOCAL”;
➤ turn the switch to position “ OIL” for oil operation and “GAS” for
gas operation.
5.7.1 Adjusting gas/air delivery
➤ Move slowly towards the maximum output (butterfly gas valve
completely open);
➤ adjust the required maximum output with the gas pressure sta-
bilizer;
➤ adjust the combustion parameters with the air servomotor and
store the maximum combustion point.
Complete the procedure slowly, synchronizing the combustion with
the two servomotors and storing the different setting points.
5.7.2 Flame signal measurement
Check the flame signal through the parameter 954, as indicated in
Fig. 31. The displayed value is expressed in percentage.
For further and specific information, please refer to the specific in-
struction manual.
The value during the operation must be higher than 24%. If at the
burner start-up the value is higher or equal of 18%, the burner locks
out due to the extraneous light.
The display (Fig. 31) shows parameter 954: flashing on the left.
On the right, the flame’s intensity is displayed as a percentage.
Example:
954: 0.0
DANGER
Make sure that the lamps or testers connected to
the solenoids, or indicator lights on the solenoids
themselves, show that no voltage is present.
If voltage is present, stop the burner immediately
and check the electrical wiring.
When the burner starts, check the direction of the
motor rotation, as indicated in Fig. 30.
As the burner is not fitted with a device to check the
sequence of the phases, the motor rotation may be
incorrect.
As soon as the burner starts up, go in front of the
cooling fan of the fan motor and check it is rotating
anticlockwise.
If this is not the case:
➤ place the switch in position “0” and wait for the
control box to carry out the switch-off phase;
➤ disconnect the electrical supply from the
burner;
➤ invert the phases on the three-phase power
supply.
WARNING
For the start-up procedure and the parameters cal-
ibration, refer to the specific instruction manual of
the
LMV36.5...
electronic cam supplied with the
burner.
