Safety Manual

9106 HART® transparent repeater

9. failure category SIl 2 / SIl 3

10. Periodic proof test procedure

This test will detect approximately 95% of possible “du” (dangerous undetected)
failures in the module.

11. Procedures to repair or replace the product

Any failures that are detected and that compromise functional safety should be
reported to the sales department at PR electronics A/S.
Repair of the module and replacement of circuit breakers must be done by PR
electronics A/S only.

12. maintenance

No maintenance required.

Step action

Bypass the safety PLC or take other appropriate action to avoid a false trip

Connect a simulator identical to the input setup

Apply input value corresponding to 0/100% output range to each channel

Observe whether the output channel acts as expected

Restore the input terminals to full operation

Remove the bypass from the safety PLC or otherwise restore normal operation
