below the "Feed required" point. The pressure value for "Feed required" is about 1 bar above
the switching value "Alarm ON".

The leak detector is not designed with a safety valve, but one can be added if the application
requires it. (Please consult the manufacturer).

Switching off the acoustic alarm signal:
Briefly press the "Acoustic alarm" button once – the acoustic alarm signal is then switched
off and the red LED flashes.
Pressing the button again will cause the acoustic signal to be switched on.
This function is not available in normal operation or during malfunctions.
Testing the visual and acoustic alarm signal
Press the "Acoustic alarm" button and keep it pressed (approx. 10 seconds) – the alarm
signals are triggered until the button is released again.
This test is only possible if the pressure in the system has exceeded the "Alarm OFF"
pressure level.
