VOLTAGE CONTROL OF ELECTRODES
PAGE 24
Carried out when checking the ignition coil and ignition oscillator.
During ignition control, the solenoid coil connector must be disconnected.
Access to the burner unit is obtained by removing the end flange of the burner, unscrewing the three
6 mm nuts, and removing the burner.
Remove and cover the photocell to prevent it from being exposed to light.
Start the burner. Voltage discharges at the electrodes can now be observed. The automatic controls
provide power to the ignition oscillator and ignition coil of the ignition system via connector A, pin 2
(see page 32).
The ignition coil and oscillator are mutually connected and do not work separately.
The ignition oscillator picks the minus of the operating current apart, and these pulses are then
transformed by the ignition coil to high voltage, discharged as a spark between the igniters.
If no charge occurs, the causes may be:
1. Defective ignition cable.
2. Electrode settings.
3. Dirt on the electrodes.
4. Defective ceramic coating on the electrode unit.
5. Ignition coil, oscillator, automatic controls.
