- Press the button for 3 seconds, “CONF” is displayed then “NEG”, meaning that the relay is in negative security, it is
excited during an alarm condition.
- If needed, press quickly the button to switch the relay in positive security, the relay is de-energized during an alarm
condition or a current breaking, “POS” is displayed.
- Press 3 seconds the button, “Buzz” screen is displayed with “ON” or “OFF” blinking. Briefly press on the button to
activate (“ON”) or deactivate (“OFF”) (according to the last saved configuration) the buzzer during an alarm condition.
