Product Line:
ATS48
Environment:
All models

- Unplug the cable from the Soft Starter's Modbus port and power cycle. If the display on the Soft Starter is now functioning properly, the keypad (VW3G48101) and/or cable need to be replaced.
- You can also try reseating the ribbon cable between the control board and the power board. Remove line voltage AND control voltage before performing these steps.
- Remove the four screws holding the front control board and pull the control board off slowly
- Re-seat both ends of the ribbon cable connecting the control board to the power board. Make sure the cable is connected firmly
- Return line voltage and control voltage to the soft starter
