Alarm relays


The program has the capacity to manage up to four alarm relays. Each alarm is enabled depending
on whether or not the relevant parameter, Alarm DO position, has been set. To enable, simply set
this to a value other than zero, if the value remains at zero, the alarm relay is not used.
The four relays, with relevant parameters, are listed below:

General alarm relay - Global alarm DO position

Circuit 1 alarm relay - Circuit 1 alarm DO position

Circuit 2 alarm relay - Circuit 2 alarm DO position

Circuit 3 alarm relay - Circuit 3 alarm DO position
