There are two possible configurations for the SIGNALLING module:
- default configuration: digital input, contacts with pole common, independent contact;
- alternative configuration: independent contacts.3.3.2 Front view
- "Power" LED (lit when Vaux PR120/V are installed)
- LED: associated with the signalling contacts.4 haracteristics the igital input
The unit enables the digital input associated with the following functions:
- enabling alternative set parameters, set (PR123/P only);
- outside trip control;
- zeroing release trips;
- resetting PR120/K contacts;
- local/remote enabling;
- resetting energy meters. this case, the digital input wired, but not brought the terminal block.
