7. Mounting
CAUTION
Safety switches must not be bypassed (bridging of contacts), turned away, removed or otherwise
rendered ineffective.
Ì
Observe EN ISO 14119:2013, section 7, for information about reducing the possibilities for by-
passing an interlocking device.
NOTICE
Risk of damage to equipment and malfunctions as a result of incorrect installation.
Ì
Safety switches and actuators must not be used as an end stop.
Ì
Observe EN ISO 14119:2013, sections 5.2 and 5.3, for information about fastening the safety
switch and the actuator.
Ì
From the assured switch-off distance S
ar
, the safety outputs are safely shut down.
Ì
When mounting several safety switches, observe the stipulated minimum distance to avoid mutual
interference.
.
min. 140 mm
Ì
If the actuator is installed flush, the switching distance changes as a function of the installation
depth and the safety guard material.
Ì
Observe direction of arrow on the device (see figure below).
Permissible approach directions
A
B
C
D
Note the following points:
Ì
Actuator and safety switch must be easily accessible for inspection and replacement.
Ì
Actuator and safety switch 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. To avoid
entering the area of possible side lobes, a minimum distance is to be maintained in case of a side approach direction.
See chapter 11. Technical data, section Typical operating distance for the related actuator.
-when the safety guard is open up to the distance S
ar
(assured switch-off distance), a hazard is excluded.
-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.
Ì
Pay attention to the maximum tightening torque for the read head or safety switch and actuator mountings of 0.8 Nm.
