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
S
ar
with non-flush installation
Installing the safety switch non-flush within electrically or magnetically con-
ductive material, the value for the assured release distance
S
ar
can change.
– Check the assured release distance
S
ar.
}
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
).
}
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 pre-
vented.
}
Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch type 4 with coding level Low.
