12.2 Fault causes
In case of a failure the LED is permanently illuminated.
Every 10 seconds the illumination is interrupted by a
flash code.
In case of all failures the gas supply is interrupted.
Fault Possible cause:
Burner not working =>
shut down - no heat demand
- no mains supply
- voltage < 187 V
- continuously tension on
terminal A
2-3 seconds after apply-
ing mains =>
lock out - control box not reset
Burner starts, no flame
=> lock out - false flame detected
- no
ignition
- no gas supply
Burner starts, flame
established => lock out
after safety time (Ts) - ionisation current < 1,5 µA
- phase and neutral
reversed
- ionisation probe damaged
or dirty
