properly powered and that the signal cable is correctly

connected.

Check that;

No short-circuit is present

•

The probes were not damaged during installation, that no excessive current absorption is

present

Check that the connection cables are not shortcircuited, that the polarity has been inverted and the

battery is not damaged.

Check that there are no gas leaks

If the alarm signal and the fault indicator LED turn on together, check the sensor.

Check that the wiring is correct and that the DIP switch has been set properly. All relays must be

free from electrical powe. Check the drawing of the connections.
