The interlock controls work when the local
selector is in LOCAL or in REMOTE. The ESD
control overrides the interlock controls. The
following options can be configured:
• Interlock OP: active when signal is PRESENT,
active when signal is ABSENT, no action
(OFF).
• Interlock CL: active when signal is PRESENT,
active when signal is ABSENT, no action
(OFF).
