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.

Voted Inputs

Non-voted Inputs

For analog inputs, fault contacts are set for:

HGenius faults

HDiscrepancy 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.
