If the actual CO or O values lie outside their respective ranges, proceed as follows
2 2
1. Check the ionisation electrode and connecting cable
2. Check the electrode gaps
Fig.: Ignition electrode gap
Fig.: Ionisation electrode gap
Check the electrodes for wear and contamination.
Clean the electrodes with a small brush (not a wire brush) or sandpaper.
Check the electrode gaps. If the gaps do not correspond to the drawing or the electrodes are damaged, replace the elec-
trodes and gaskets and align them.
Tighten the electrode fixing screws with a torque of 3.0 Nm.
3. Carry out a 100 % calibration after working on the ionisation electrode.
Þ see description HG43 in chapter "Parameter description"
4. If the CO or O value remains outside the respective range, the flue gas values can be adjusted via parameter HG43.
