3. Mounting
3.1 General mounting instructions
Fitting is only authorised in a de-energised condition
The component can be mounted in any position. The only condition
is that, the active surface of the safety sensor and the actuator are
opposite. The distance between both surfaces must be smaller than
7 mm when the safety guard is closed. The safe switching distance s
ar
must be observed.
The sensor enclosure must not be used as an end stop. The safety
sensor must only be used within the assured switching distances s
ao
and s
ar
.
The safety sensor and the corresponding actuator can be fixed
using the supplied M18 nuts (A/F 24). The max. tightening torque of
the supplied screws is 500 Ncm. Alternatively, the H18 fixing clamp
(accessory) can be used for the fixation of the safety sensor.
A concealed mounting is possible, however this reduces the switching
distance. The reduction will be lower, when the sensor protrudes a
few mm.
The CST 180-1 actuator has two fixing holes displaced by 90°.
The max. tightening torque of the supplied screws is 100 Ncm.
The CST 180-2 actuator is screwed into a prepared tapped hole
M 18 × 1. Use the slot to the front.
Safety sensor and actuator must be permanently fitted to the
safety guards and protected against displacement by suitable
measures (tamperproof screws, gluing, drilling of the screw
heads).
To avoid any interference inherent to this kind of system and any
reduction of the switching distances, please observe the following
guidelines:
• The presence of metal chips in the vicinity of the sensor is liable to
modify the switching distance
• Keep away from metal chips
• Minimum distance between two sensors: 100 mm
Please observe the recommendations regarding maximum
impact energy, actuating speed and tightening torque in the
technical data.
Please observe the relevant requirements of the standards
ISO 12100, EN 953 and ISO 14119.
