Option
Function
Selects the function of Relay A.
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-
ture Flag
The relay closes when the motor temperature flag activates (see
parameter 8-9 Motor Temperature Flag
).
Soft Brake Relay
The relay closes when the soft starter receives a stop signal, and remains closed until the end of soft
brake.
Reversing Contac-
tor
The relay controls an external contactor, for reverse operation.
Trip Failsafe
The relay closes when control power is applied. The relay opens if the soft starter trips or if control power
is lost.
