}
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 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 S
ao
and the assured release distance S
ar
must be tested
under real conditions.
}
Do not apply any installation tools (e.g. Pliers) on the surfaces of the switch.
}
If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected.
}
Protect the safety switch and actuator from UV light or direct sunlight.
}
The protection type (see
) can only be achieved by using the
Pilz connection leads available as an accessory.
Installation of safety switch
Sensing face
Slide the switch through the hole in the
mounting surface with the sensing face to-
wards the actuator.
Attach the switch using 2 M12
hexagonal nuts with special threads.
Note the max. torque setting (see
