4.4.4 Fail
A fail contact is energized when a fail is detected. When a fail is detected, the contact output is

Select sensors from “Sensor 1-1”, “Sensor 1-2”, “Sensor 1-3”, “Sensor 1-4”, “Sensor 2-1”,
“Sensor 2-2”, “Sensor 2-3”, “Sensor 2-4.”
Fail is output only by the sensors you select. Fail from FLXA402 is always valid.
NOTE
When an internal communication error occurs, a fail is output. However, the error location would

or “Maintenance Required”.
When Failure happens, contact output stays On (S1/S2/S3: close, S4: open).
