Outputs
4.4.1
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.
4.4.2
Programmable Output
The programmable output relay (terminals 23, 24) can be used to signal either trip or run status. This relay is
normally open.
Trip:
The relay closes when the VersiStart i II trips. The relay can be used to operate the shunt-trip mechanism of
an upstream circuit breaker (in order to isolate the motor branch circuit), or to signal the trip to an automation
system or externally. The relay will open when the trip is reset.
Run:
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.
