Troubleshooting - Sime Brava Slim BF Manual De Instalación Y Mantenimiento

To enter "Parameter setting and display"refer to the indications
provided in the specific section.
Once the parameters in the table have been set, you must carry
out the "Automatic calibration procedure".
If the gas valve and/or the ignition/detection electrode and/or the
are replaced, the user must still carry out the entire phase
fan
of "Automatic calibration procedure" described in the specific
section.

Solution
- Restore pressure
- Check for any leaks in
the system
- Empty the system via
the drain valve on the
hydraulic assembly and
bring the pressure to
approximately 1.2 bar
- Check connections
- Replace the sensor
- Check connections
- Replace the sensor
- Check the integrity of
the electrode and check
that it is not grounded
- Check gas availability
and pressure
- Check the integrity of
the gas valve and the
card
