Relay A is a changeover relay.
Off Relay A is not used.
Ready The relay is closed when the soft starter is in Ready state.
* Run The Run output closes when the soft start is complete (when the starting current drops below 120% of
the programmed motor full load current). The output remains closed until the beginning of a stop (ei-
ther soft stop or coast to stop).
Warning The relay closes when the soft starter issues a warning.
Trip The relay closes when the starter trips.
Low Current Flag
The relay closes when the low current flag activates while the motor is running (see parameter 8-7 Low
Current Flag).
High Current Flag
The relay closes when the high current flag activates while the motor is running (see parameter 8-8 High
Current Flag).
Motor Tempera-
The relay closes when the motor temperature flag activates (see parameter 8-9 Motor Temperature Flag).
ture Flag
Soft Brake Relay The relay closes when the soft starter receives a stop signal, and remains closed until the end of soft
