Unit features

` The actuator PSEN 2,1-10 belongs

to the safety switch

` 2 reed contacts (1 N/C, 1 N/O)
` Assured operating distance: 6 mm
` Assured release distance: 25 mm
` Square design
` Works magnetically
` Switching voltage 24 VDC
` Series connection via PSEN i1 in-

terface

` LED to display switch status

Unit description

The safety switch meets the require­ments of EN 60204-1 and IEC 60204-

1.
The safety switch only complies with
EN 60947-5-3 in conjunction with the
actuator PSEN 2,1-10 and its ap­proved evaluation devices.
The safety switch should only be con­nected to the evaluation devices listed
under "Connections".

Function description

If the actuator is within the response
range, the magnets switch the reed
contacts on the safety switch. If the
actuator is outside the response range
(safety gate open), the reed contacts
on the safety switch will switch.

` When using evaluation devices with

delay-on de-energisation contacts,
please note:
–Delay time ≤ 30 s: Delay-on de-

energisation contacts satisfy the
requirements of category 3 in ac­cordance with EN 954-1 and the
requirements of a PDF with sin­gle-fault tolerance (PDF-S).

–Delay time ≥ 30 s: Delay-on de-

energisation contacts satisfy the
requirements of Category 1 in
accordance with EN 954-1 and
the requirements of a PDF with
designed reliability (PDF-D).

` In the following commissioning cas-

es, check the function that detects
shorts across contacts:
– On evaluation devices with DC

supply voltage: Overall cable re­sistance ≥ 15 Ohms per channel

– On evaluation devices with AC

supply voltage: Overall cable re­sistance ≥ 25 Ohms per channel

– For details of how to perform the

test for shorts across the con­tacts, please refer to the operat­ing manual for the relevant
evaluation device.

Connections

NOTICE

The colour marking for the connection
lead only applies for the cable that Pilz
supplies as an accessory.
The safety switch is shown in an unop­erated condition.
