What would cause the ATS48 HMI to randomly and continuously cycle or scroll through menu selections?

Issue:
What would cause the ATS48 HMI to randomly and continuously cycle or scroll through menu selections? 

Product Line:
ATS48

Environment:
All

Cause:
HMI display is unstable

Resolution:
The HMI (keypad) could be scrolling, or the Soft Starter's display could be scrolling. Or they could BOTH be scrolling. 
This typically indicates a problem with the control circuitry or keypad button.
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. 

If the integral display continues scrolling (after the cable is unplugged from the Modbus port and you've power-cycled the ATS48), replace the control board, part number VX4G481.
