7.3 Alarm relays
The program has the possibility of managing up to three alarm relays. The activation of each of these devices is
linked to the setting or lack thereof of the relative DO alarm position parameter. For activation, it is sufficient
to set this value to a value that is different than zero; if the zero value is maintained, the alarm relay is not used.
A list of the three relays, with their relative parameter, is presented below:
- A general alarm relay – Global DO alarm position
- An alarm relay for circuit 1 - DO alarm position circuit 1
- An alarm relay for circuit 2 - DO alarm position circuit 2
Through the relative parameter, it is possible to establish the polarity (NO or NC) of the various alarm outputs.
