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.
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.

sition. However, safety switches
and actuators must be positioned
opposite each other in parallel:
` If possible, do not install the safety
switch and actuator on to ferromagnetic material. Changes to the operating distances are to be expected.
In this case, use the spacer available under order number 534 310.
` Safety switches and actuators
should only be secured using M4
screws with a flat head (e.g. M4
cheese-head or pan head screws).
Torque setting max. 1 Nm. Use
screws made of non-magnetic material (e.g. Messing).
` The distance between two systems
comprising safety switch and actuator must be at least 25 mm.
` Safety switch and actuator
– Keep away from iron swarf
– Do not expose to strong mag-
netic fields
– Do not expose to heavy shock or
vibration
– Do not use as a limit stop

Adjustment
` The safety switch may only be used
with the corresponding actuator
PSEN 2,1-10.
` Always test the function with one of
the approved evaluation devices.
` The LED lights when the reed con-
tacts are unoperated (safety device
open or safety switch and actuator
wrongly adjusted). The LED is in the
safety switch's N/C circuit. The LED
goes out when the reed contacts
are operated.
` The stated operating distances (see
Technical details) only apply when
the safety switch and actuator are
installed facing each other in parallel. Operating distances may deviate if other arrangements are used.
Note the maximum permitted lateral and vertical offset (see "Operating distances" and "Max. lateral
and vertical offset").
This data sheet is only intended for use
during configuration. For installation
and operation, please refer to the operating instructions supplied with the
unit.
