Fault Causes Fault rectification
The flame monitor switches to fault
condition during operation.
The ignition flame has been extinguished.
Possible cause
- Pressure in combustion
chamber fluctuating.
Provide for differential pressure control on the
gas and air side.
- Gas and air pressures
fluctuating.
- Main flame is influenced
by flows in the combus
tion chamber or due to
external deflection.
Correct the installation position and power of
the ignition burner.
- No combustion air in the
combustion chamber.
Despite the closed gas valve, the
flame monitor outputs a flame
signal.
The gas valve is leaky, so
that a small flame arises.
Replace leaky gas valve.
