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.
