Reset

Trips can be cleared by pressing the Reset button on the soft starter, sending a Reset command from the
serial communications network, or by switching the control inputs.
To clear a trip via the control inputs, the soft starter requires a closed to open transition on the stop input
(DI2).

In three-wire control, use the external stop pushbutton to momentarily open the stop input (open
CSL-DI2).

In two-wire control, if the soft starter tripped with a start signal present, remove the start signal (open
CSL to DI1, DI2).

In two wire control, if the Digistart CS tripped with no start signal present (e.g. Digistart CS motor
thermistor trip), apply then remove the start signal (close then reopen CSL to DI1, DI2).
The Reset button is located on the front of the unit, above the adjustment switches.
The soft starter will trip again immediately if the cause of the trip still exists.
