Signal Terminal
The Signal Terminal provides a way to export a
logic signal to a PLC from a transistor-type
optocoupler. Any fault light, except the Service
Interval light and the unlabeled lights, causes the
optocoupler to pass a DC logic signal to a
connected PLC for approximately 0.5 seconds.
Typical circuits to use this signal are illustrated in
Signal Terminal.
