ADAPT-Lite question

[Jeremy Mange]

This is a minor point, but I thought I would ask to try to ensure I am
understanding the problem correctly. Referring to the diagram on the
top of page 6 of the Industrial Track description document -- since
sensor ISH262 is not provided (though pictured), I believe there is no
way to differentiate between the faults CB262-FailedOpen and INV2-
FailedOff. Is that true?

[Scott Poll]

Yes, that's true. In fact there are four ambiguity groups for ADAPT-
Lite with the given instrumentation:
(i) AC483 failed off and EY272 stuck open,
(ii) FAN416 failed off and EY275 stuck open,
(iii) DC485 failed off and EY284 stuck open, and
(iv) INV2 failed off and CB262 failed open.

In each case however, the recovery action is the same for both faults
in the ambiguity group.
