OutputRelayOperationAssignment(Releasenumbers4andlater)
For this function, there are relays labeled “FAIL” and “Status” on the rear panel.
You can assign the operations explained below to these two relays. On a relay that has
been set to “Status relay,” you must also set the DX status that will be relayed.
FAILOutput
When a failure occurs in the CPU of the DX, a relay contact signal (1 signal) is output.
The relay is energized when the CPU is normal and de-energizes when a CPU failure
occurs. Therefore, relay output is carried out also when the power is turned OFF (including
a power failure). You cannot change this behavior.
