Discrete Output Fault Contacts for GMR

For discrete outputs, the fault contact is associated with the logical outputs (outputs from the application program).

Contact References Associated with an Output
Logical	Physical
reference	reference
Fault
contact

These logical references are copied to the physical output references. If a fault is detected on a physical output, the fault contact associated with that output's logical reference is set.

Conditions that Cause Discrete Output Fault Contacts to be Set

The following illustration summarizes the conditions that cause discrete output fault contacts to be set for logical, physical, and non-redundant outputs.

•Genius fault

•Discrepancy fault

•Discrepancy fault

•Genius fault

•Autotest fault

•Discrepancy fault

HFor redundant outputs, the fault contact is set and fault messages logged for:

hAutotestfault

hGeniusfaults including Loss of Block, and the following additional faults:

Failedswitch: Occurs if the actual output state differs from the commanded state.

No-loadfault:For 16-circuit blocks only, individual outputs can be configured to enable or disable reporting No-load faults. The minimum load current required to assure proper no-load reporting is 100mA (not 50mA, as it would be for a block not used in a GMR group).

For a 4-block group, a system output no-load fault is produced if outputs are

ON; blocks A and B or blocks C and D report no-load faults.
