Functional Safety SJ2-SN, SJ3,5-S(1)N

Operation

5

Operation

Operating the device

1.

Observe the safety instructions in the instruction manual.

2.

Observe the information in the manual.

3.

Use the device only with devices that are suitable for this safety application.

4.

Correct any occurring safe failures within 8 hours. Take measures to maintain 

the safety function while the device is being repaired.

5.1

Proof Test

If you perform a proof test for the safety loop, the following steps are necessary:

Check the device for housing damages. If moisture penetrates into the device 

or internal components of the device are damaged, this can lead to unpredictable effects.

Check that the device is working correctly. If the device is not working correctly 

or not working, replace the device.

For this proof test, no proof test coverage (PTC) can be claimed as only a full functional test 

with the defined reference object over the temperature range can reveal an unacceptable 

dislocation of the switching point (PTC = 100 %). But the safety characteristic values 

are considered low enough to continually manage without proof test.

Danger!

Danger to life from missing safety function
If the safety loop is put out of service, the safety function is no longer guaranteed.

Do not deactivate the device.

Do not bypass the safety function.

Do not repair, modify, or manipulate the device.
