Note the following points:
Ì
Actuator and read head must be easily accessible for inspection and replace-
ment.
Ì
The switching operation must only be triggered by the specific actuator desig-
nated for this purpose.
Ì
Actuator and read head must be fitted so that
Ì
the front faces are at the minimum switch-on distance 0.8 x S
ao
or closer
(see section Operating distances). To avoid entering the area of possible side
lobes, a minimum distance is to be maintained in case of a side approach
direction. See section Typical operating distance for the related actuator.
Ì
when the safety guard is open up to the distance S
ar
(assured switch-off dis-
tance), a hazard is excluded.
Ì
the actuator is positively mounted on the safety guard, e.g. by using the
safety screws included.
Ì
they cannot be removed or tampered with using simple means.
Ì
Pay attention to the maximum tightening torque for the read head or safety
switch and actuator mountings of 1 Nm. For read heads/actuators made of
PE-HD, the maximum tightening torque is only 0.5 Nm.
