Measuring ionisation current

The ionisation current must be measured during burner start-up and maintenance or after a fault indication in the control box.

Measurement of ionisation current shortly after burner start during:

• Maintenance

• Start-up

• Fault indication.

The ionisation current can also be read out as a percentage via SatroPen.

To do so:

• Open plug connection between cable to control box and cable from ionisation electrode.

• Connect ammeter in series. Measuring range 0...200

µA DC.

l > 2 µA l < 2 µA

- OK

- Unsafe operation !

- Clean burner pipe

- Bend ionisation rod in flame area

- If necessary, replace combination electrode

- If necessary, reverse polarity on ignition transformer (induction current)

- Eliminate moisture and deposits.

Servicing air pressure monitor

• Detach silicone connecting hose and clean, check switching function.

• Replace air pressure monitor if switching function is no longer O.K.

To do so:

• Switch burner voltage-free and disconnect (7-pin connector X11).

• Unscrew cover.

• Disconnect electrical connectors.

• Release retaining screws on motor.

• Reassemble in reverse order.
