9.12 Fault switch-off
Safety switch-off in case of flame failure during the operation.
After every safety switch-off a new ignition attempt is carried out as per program.
If this does not result in flame formation a fault switch-off occurs.
In case of fault switch-off, the reset button on the control panel should be pressed.
In case of operation disturbances (bell symbol in thew display), the digit in the dis-
play on theoperating panel points out the cause of the disturbance (see fault code
table).
Burner does not start:
- No voltage at the control and regulating centre
- no “burner ON“ signal from the heating circuit control (see
fault code table
)
Burner goes into disturbance status:
Without flame formation:
- No ignition
- ionisation electrode has ground connection
- no gas
In spite of flame formation the burner goes on fault after expiration of the safety
time:
- Ionisation electrode defective or soiled.
- Ionisation electrode does not penetrate the flame
