How do I perform a walk test on the EST4, and can individual SLC loops be isolated for testing?

I couldn't find the specific walk test procedure for the EST4 in the provided manuals, though the system uses test commands for periodic inspections (Page 64) [1].

Individual SLC loops can be isolated for testing; for example, the manual describes isolating ground faults on an EST4 by opening the loop at the 50% mark to identify the faulted segment (Page 165) [1].

It is also recommended to test all field wiring for continuity and resistance before connecting it to the control unit (Page 84) [1].
