2 Valve leak detection test not possible

The valve leak detection is active, but the minimum gas

pressure switch is selected as input for X9-04 (check

parameters 238 and 241)

3 Valve leak detection test not possible

The valve leak detection is active, but no input has been

assigned (check parameters 236 and 237)

4 Valve leak detection not possible

Valve leak detection is active, but 2 inputs have already been

assigned (configure parameter 237 or maximum gas Pressure

switch or POC)

5 Valve leak detection not possible

The valve leak detection is active, but 2 inputs have been

assigned (check parameters 236 and 237)

14 # POC

0 POC Open Check if the closure contact of the valve is closed

1 POC Closed

Check the wiring

Check if the closure contact of the valve opens when the valve

is checked

64 POC Open - Alarm lockout at start

Check the wiring

Check if the closure contact of the valve is closed

19 80 Fuel pressure, POC - Alarm lockout at start

Check that the pressure switch is closed when no pressure is

present from the fuel

Check that there are no short-circuits

20 # Pmin

0 Minimum gas/oil pressure absent Check that there are no line interruptions

1 Scarcity of gas - Alarm lockout at start Check that there are no line interruptions

21 # Pmax/POC

Pmax: Max. gas/oil pressure exceeded
