Parameters
2.8. Alarms
The SITRANS LUT400 supports eight alarm types. Any alarm can be assigned to any
available relay.
It is possible to assign more than one alarm to the same relay. In this case, the relay
will activate if any one of the alarms is activated. If no alarms are activated, the relay
will become inactive.
For details on relay behaviour under fail-safe conditions, see Alarm relays on page
66.
