Users want to monitor phase A voltage and set the over-limit to 120% Ue, linking with
relay 1, set the delay time to 30s. If the actual phase A voltage exceed to the limit and
lasting to 30s, then the relay 1 will output the signal. If the phase A voltage return to
limit value within 30s, the relay 1 will not respond.
Note
1. If set the delay time to 0, it means setpoint channel will be activated once the
object over/ under limit.
2. If no setting the monitor object, it means no relay alarm function.
