Analog Fault Contacts for GMR
As for discrete inputs, voted analog inputs have fault contacts associated with both the
raw data inputs and the corresponding voted inputs. Non-voted analog inputs also have
associated fault contacts.

For analog inputs, fault contacts are set for:
Genius faults
Discrepancy faults
For analog outputs, a fault contact is set for any Genius fault, including Loss of Block.
See page 5-28 for detailed information on conditions that cause analog fault contacts to
be set.
Analog Alarm Contacts for GMR
For analog data, there are two additional types of diagnostic contacts that can be used in
the application program, the High Alarm and Low Alarm contacts. These contacts
indicate when an analog reference has reached one of its alarm limits. Alarm contacts are
not considered to be fault contacts.
Alarm contacts for a GMR system are the same as for a conventional system.
