7.2 Alarm table

pRack pR300T can manage both alarms relating to the status of the digital inputs and to system operation, similar to the pRack pR300. For each alarm, the

following are controlled:

•

The actions on the devices, if necessary

•

The output relays (one global and two with diff erent priorities, if confi gured)

•

The red LED on the terminal and the buzzer, where present

•

The type of acknowledgement (automatic, manual, semiautomatic)

•

Any activation delay

The complete list of alarms for the pRack pR300T with the related information as described above, is reported below.
