2.4. Signalling logic for voltage presence and/or absence
The output contacts and the power supply to the unit are
accessible on a “J” terminal block for on-site connection.
The signalling logic for the absence and/or presence of
voltage depends on how the connections are made on the
output “J” terminal block.
The logic schemes that can be obtained are indicated
below:
2.4.1. Independent Logic
With this type of logic, the unit provides a contact that
indicates the absence and/or presence of voltage for
each phase. The terminals to be accessed to obtain the
information, according to this operating logic, are given in
the following figure:
Phase L1 indication: terminals J1-3 and J1-4
Phase L2 indication: terminals J1-5 and J1-6
Phase L3 indication: terminals J1-7 and J1-8
