Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282*

Safety Recommendation

3.4

Installation and Commissioning

During installation all aspects regarding the SIL level of the loop must be 

considered. The safety function must be tested to ensure the expected outputs 

are given. When replacing a device, the loop must be shut down. In all cases, 

devices must be replaced by the same type.
