Mounting and Installation
Mounting and Installing the Device
1. Observe the safety instructions in the instruction manual.
2. Observe the information in the manual.
3. Observe the requirements for the safety loop.
4. Connect the device only to devices that are suitable for this safety application.
5. Check the safety function to ensure the expected output behavior.
4.1
Mounting
Mounting the Measuring Plate
1. If you are using a custom-specific measuring plate, check the operating distance
in your application under realistic environmental conditions.
The measuring plate is suitable if the measured value does not differ
by more than 10 % from the rated operating distance.
2. Fasten the measuring plate so that the measuring plate does not come loose or get lost.
4.2
Installation
Connecting the Sensor
1. Connect the device in safety applications up to SIL 2 to a control unit according
to EN 60947-5-6 (NAMUR).
Observe the limitations, see chapter 1.2.
2. Observe that the insulation resistance must be greater than 1 M
.
Insulate the single wires from any other electrical connections.
3. Observe that the loop resistance must be less than 50
.
4.3
Configuration
A configuration of the device is not necessary and not possible.
Danger!
Danger to life from missing safety function
An incorrectly mounted, incorrectly positioned or missing measuring plate can lead to failure
of the safety loop.
• Fasten the measuring plate in a suitable manner.
• For SN sensors: Do not remove the measuring plate.
