4.1

Mounting

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.
Mounting the Measuring Plate
1.
Mount the measuring plate with the correct rated immersion depth (lateral) s
distance to the slot base d, see chapter 3.3. Observe the ambient conditions.
2.
Fasten the measuring plate so that the measuring plate does not come loose or get lost.

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 3.2.
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.
Connect the device in safety applications up to SIL 3 to a control unit for
SIL 3 safety applications.
Pepperl+Fuchs offers control units for SIL 3 safety applications,
i. e. switch amplifier KFD2-SH-Ex1. Observe the limitations, see chapter 3.2.
