Ionisation electrode (1)
The ionisation electrode must always be in contact with the flame.
- switching threshold at 1 µA DC
- max. achievable current 10 µA DC
The distance from the ionisation electrode to the blast tube must be maintained in
accordance with
Fig. 33
. 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!
Please note 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 ammeter 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. 33
10.10 Fault switch-off
Safety switch-off in case of flame failure during the operation.
