Function description
The contact expansion module PZE 9 is an add-on device without delay-on de-energisa-
tion. It is used to expand a safety circuit. The contact expansion module is driven by a base
unit (e. g. emergency stop relay). When operating voltage is supplied the "POWER" LED
will light.
} Functional procedure once the input circuit is closed (e.g. safety contacts on the base
unit are closed):
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74 and 83-84 close,
auxiliary contact 91-92 opens.
– The LEDs "CH.1" and "CH.2" illuminate.
} Functional procedure once the input circuit is opened (e.g. safety contacts on the base
unit are opened):
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64, 73-74 and 83-84 are
opened redundantly, auxiliary contact 91-92 is closed.
– The LEDs "CH.1" and "CH.2" go out.
