Setpoint;
This decides the value to activate contact output (S1/S2/S3: close, S4: open)
when an alarm occurs.
Direction:
This selects “High” or “Low” to report the value is outside of the limit.
Hysteresis:
This configures hysteresis of measurements.
Delay time:
This configures Delay time to activate contact outputs after a measurement goes
beyond the Setpoint in Direction.

Expiry time
If a contact output exceeds the Expiry time, the contact output returns Off and the operation
fails. To cancel the alarm, go to the Error code and cancel the error. If you set Expiry time to 0.0
second, it turns invalid.
