For your safety
WARNING!
Loss of safety function due to manipulation of the interlocking device
Manipulation of the interlocking device may lead to serious injury and death.
– You should prevent any possibility of the interlocking device being
manipulated through the use of a spare actuator.
– Keep the substitute actuator in a safe place and protect it from unau-
thorised access.
– If spare actuators are used, these must be installed as described in
Installation [ 12].
– If the original actuators are replaced with substitute actuators, the ori-
ginal actuators must be destroyed before disposal.

Rl / km
Imax =
Rlmax = Max. overall cable resistance (see evaluation device's technical details)
Ri = Internal resistance sensor (see Technical details [ 16])
Rl/km = Cable resistance/km of the cable (seetechnical details cable)
}Ensure the wiring and EMC requirements of EN 60204-1 are met.
}In the following cases, check the function that detects shorts across contacts prior to
commissioning:
– 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.

Installation
}The unit can be installed in any position. 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.
}Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws). Use screws made of non-magnetic mater-
ial (e.g. brass).
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.

PSEN ma1.4a-50
Operating Manual PSEN ma1.4a-50

}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
The actuator should be protected from unauthorised removal and from con-
tamination.
}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 [ 16]).
}Safety switches and actuators
– Should be kept away from iron swarf
– Should not be exposed to strong magnetic fields
– Should be used for fixed wiring only
}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 pre-
vented.
}Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch design 4 and with level of coding 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.
