Assembly
Mounting Location
• Select the mounting location so that the sensor and actuator are accessible
for maintenance work and are protected against damage.
• Select a mounting location for the sensor that is as far away from the door
hinge as possible.
• If necessary, fit an additional stop for the moving protective device.
Distance
When several safety switches are mounted to the machine, they must be mounted
at a minimum distance to one another see Mount Multiple Safety Switches on
page 19
Alignment
The safety switch can be mounted in any alignment. When mounted
horizontally, the anchor plate with rotating bearings increases the manipulation
protection. When mounted horizontally, if the movable physical guard triggers
the actuator, the magnet holds the actuator. As the anchor plate has rotating
bearings, the gravitational force rotates the actuator surface away from the sensor
surface and the OSSDs go into the OFF state.
Mounting Methods
The sensor can be mounted in the following ways:
• Surface mount: The sensor is mounted on the fixed part of the protective
device (for example, door frame).
• Flush mount
(1)
: The sensor is mounted in the fixed part of the protective
device (for example, door frame). There must be a suitable recess in the
mounting surface. The thickness of the mounting surface must be
1.5…3 mm (0.06…0.12 in.).
ATTENTION: Bypassing the protective device.
Hazard due to lack of effectiveness of the protective device.
Avoid incentives to manipulate the safety switch by taking at least one of the
following measures:
• Cover the sensor and the actuator with additional equipment or protect them
against access.
• If possible use permanent mounting methods for actuators (for example, glue,
safety screws, or rivets).
