Installation position

The unit can be installed in any posi­tion.
However, the sensing faces of the
safety switch and actuator should be
positioned opposite each other in par­allel.
Operating distances may deviate if
other arrangements are used.

Further information about the operat­ing distances and the maximum per­mitted lateral and vertical offset can be
found in the chapters entitled “De­scription” and “Units”.

On units with a round M30 design,
make sure that the two notches are
exactly opposite each other. A nib on
the actuator prevents it twisting.

On units with a round M12 design,
make sure that the two bevelled sur­faces are exactly opposite each other.

Installation guidelines

Safety switch and actuator

` Keep away from iron swarf
` Do not expose to strong magnetic

fields

` Do not expose to heavy shock or vi-

bration

` Do not use as a limit stop
` Where possible do not install on top

of ferromagnetic material (changes
in the operating distances can be
expected). In this case, units in the
square design can use the spacer,

order number 534 310.
The distance between two systems
made up of safety switch and actuator
must be at least 25 mm (see installa­tion example, “Safety switches on
swing gates”)

Attachment

Attach the safety switch to the fixed
part of the safety device.

Square design:

` 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 ma-

terial (e.g. Messing).

Round design:

` Secure the safety switch using the

M30 or M12 nuts provided. The

torque setting for the nuts is max.

300 Ncm.

The actuator should be secured per­manently to guarantee security against
manipulation.

Adjustment

` The safety switch may only be used

with a corresponding actuator.

` The actuator must not make con-

tact with the safety switch. Please

note the minimum operating dis-

tance stated in the technical details.

` Always test the function with one of

the approved evaluation devices.

` Some safety switches have an LED.

There are 2 types:

– The LED lights when the con-

tacts are unoperated (safety de-

vice 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 contacts are operated.

– (PSEN with round M12 design

only): The LED lights when the
contacts are operated (safety
device closed). The LED goes
out when the contacts are unop­erated.

Further information about the switch­ing distances (operating and release
distance) and the maximum permitted
lateral and vertical offset can be found
in the chapters entitled “Description”
and “Units”.

Installing the interfaces PSEN i1 and
PSEN ix1

` 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 element (e.g. retaining
bracket or an end angle).

Installation accessories

Spacer for safety switch in square
design

If the safety switch and actuator are in­stalled on to ferromagnetic material,
the operating distances may vary. In
this case, use the spacer available un­der order number 534 310 (see chap­ter entitled "Accessories").

Bracket for safety switch in square
design

An aluminium bracket is available for
installing the safety switch and actua­tor at an angle. On this bracket it is
possible to adjust the position of the
safety switch and actuator (see chap­ter entitled "Accessories").

Swing gates

On swing gates the safety switch must
be positioned on the closed edge. The
distance between the two systems
comprising safety switch and actuator
must be at least 25 mm.

Concealed installation

To exclude the possibility of manipula­tion, the actuator must be fitted in
such a way that it cannot be removed
by the operator. (see section entitled
“Attachment”). Security against ma­nipulation can also be guaranteed by
concealing the installation of the safe­ty switch and actuator. A concealed
installation also reduces the risk of in­jury.
