Installation
}The unit can be installed in any position. Safety switches and actuators must be installed
so that the sensing face of the safety switch is exactly opposite the sensing face of the
actuator.
}If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected.

CAUTION!
Potential loss of safety function due to changed device properties
The unit's properties may be affected if installed in an environment contain-
ing electrically or magnetically conductive material.
– Please check the operating distances and the assured release dis-
tance.
CAUTION!
Possible loss of the safety function by changing the release distance
Sar with non-flush installation
Installing the safety switch non-flush within electrically or magnetically con-
ductive material, the value for the assured release distance Sar can change.
– Check the assured release distance Sar.
}Safety switches and actuators must be positioned so that they are secured against a
change of position.
}The safety switch and actuator should only be secured using screws and nuts made of
non-magnetic material (e.g. brass or stainless steel).
}Avoid the risk of damages from foreseeable external influences by attaching the safety
switch and actuator. If necessary, safety switch and actuator have to be protected.
INFORMATION
Protect the actuator from unauthorised removal (e.g. via a screw lock or
concealed installation) and from contamination.
}Prevent self-loosening of the fastening elements of safety switch and actuator.
}The fastening of safety switch and actuator has to be sufficiently stable to ensure the
proper operation of the safety switch and the actuator.
}The distance between two safety switches must be maintained (see Technical
details [ 17]).
}Safety switches and actuators
– Should be kept away from iron swarf
– Should not be exposed to strong magnetic fields
}Prevent the safety switch and actuator being exposed to heavy shock or vibration.
}Make sure that the safety switch and actuator cannot be used as an end stop.
}Circumvention of the safety switch in a reasonably foreseeable manner must be preven-
ted.
}Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch type 4 with coding level Low.
}Alignment errors of the guard must not adversely affect the safety function of the guard.

}The assured operating distance Sao and the assured release distance Sar must be tested
under real conditions.
}Do not apply any installation tools (e.g. Pliers) on the surfaces of the switch.
}Protect the safety switch from UV light or direct sunlight.

Adjustment
}The safety switch may only be used with the corresponding actuator PSEN ma1.3-08 VA.
}Always test the function with the PSEN ix1 interface and connected evaluation device.
}The stated operating distances (see Technical details [ 17]) only apply when the
safety switch and actuator are installed according to the specifications in
Installation [ 14]. Operating distances may deviate if other arrangements are used.
Note the maximum permitted lateral and vertical offset (see Operating distances and Lat-
eral and vertical offset [ 8]).
Periodic test
}Carry out a monthly function test on the safety switch and actuator.
}Always test the function with the PSEN ix1 interface and connected evaluation device.
}The safety function may only be checked by qualified personnel.
NOTICE
The safety functions should be checked after initial commissioning and each
time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.
