Function description
The contact expansion module PZE X5P is an add-on device without delay-on de-energisa-
tion, and 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 and 53-54 close.
– The LEDs "CH.1" and "CH.2" are lit.
– A high signal is present at the semiconductor output switch state Y32.
} 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 and 53-54 are opened redundantly.
– The LEDs "CH.1" and "CH.2" go out.
– A low signal is present at the semiconductor output switch state Y32.
Semiconductor output supply voltage Y35
} A high signal is present at semi-conductor output Y35 if the supply voltage is present
and the internal fuse has not blown.
Installation
} The unit should be installed in a control cabinet with a protection type of at least IP54.
} Use the notch on the rear of the unit to attach it to a DIN rail.
} Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an end angle).
Wiring
Please note:
} Information given in the "Technical details [ 475]" must be followed.
} The outputs 13-14, 23-24, 33-34, 43-44, 53-54 are safety contacts.
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 475]).
