5.3 Operation of the relays when the instrument is switched on
At power on, the two warning and alarm relays behave as follows:
- stay o for about 20 seconds
- are activated for about 2 seconds
- go o for about 2 seconds
- are reactivated if failsafe mode is set, or remain deactivated if failsafe mode is disabled.
5.4 Relay operating modes
The relays have two operating modes, failsafe mode and warning fault mode. These two modes can be used to select the be-
haviour of the relays based on the required alarms and in the event of sensor malfunction.
