System Manual HS3A-H21M4
11
Actuator and HS3A must be fitted so that
- the front faces are at the minimum switch-on distance 0.8 x S
ao
or closer
when the safety guard is closed (see section Operating distances and
Typical operating distance on page 28). 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.
- when the safety guard is open up to the distance S
ar
(assured switch-off
distance), a hazard is excluded. (Refer to page 28.)
- the actuator is positively mounted on the safety guard, e. g. by using the
safety screws included.
- they cannot be removed or tampered with using simple means.
Pay attention to the maximum tightening torque for HS3A and actuator
mountings of 1N·m.
