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)

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)
