10.9 Check Electrodes

Fig. 32: Electrodes

Ionisation electrode (1)

The ionisation electrode must always be in contact with the flame (switching

threshold at 1 µA DC).

The distance from the ionisation electrode to the blast tube must be maintained in

accordance with Fig. 32. When replacing the ionisation electrode, check its dis-

tance to the burner and correct if required.

Risk of electric shock!Danger of life by high tension!

Caution: Do not touch plug contacts during the ignition process!

For measurement of the ionisation current, pull plug from the gas-firing autom-

aton and connect amperemeter between plug and electrode.

Ignition electrodes (2)

To avoid an influence of the ionisation current by the ignition

- The ignition electrode must only immerse into the edge of the flame.

- The ignition spark must not spark-over to the ionisation electrode.

Installation position and electrode clearance has to be maintained according to

Fig. 32

10.10 Fault switch-off

Safety switch-off in case of flame failure during the operation.

After every safety switch-off a new ignition attempt is carried out as per program.

If this does not result in flame formation a fault switch-off occurs.
