Outputs
Main Contactor Output
The Main Contactor output (terminals 13, 14) closes as soon as the soft starter receives a start command and
remains closed while the soft starter is controlling the motor (until the motor starts a coast to stop, or until the
end of a soft stop). The Main Contactor output will also open if the soft starter trips.
The Main Contactor output can be used to directly control a main contactor coil.
Run Output
The run output relay (terminals 23, 24) can be used to signal run status. This relay is normally open.
The relay operates when the soft start is complete, the bypass relays are closed and full voltage is being applied
to the motor. The relay can be used to operate a contactor for power factor correction capacitors, or to signal
soft starter run status to an automation system.
