3.1 Introduction
The MX provides a comprehensive set of parameters to allow the use of the reduced voltage solid state starter in nearly any industrial
application. While the starter can meet the requirements of many applications right out of the box, customization of parameter values
to better suit your particular application is easily accomplished with the standard, on-board, 4-digit, 7-segment LED display/keypad.
Optionally, a 2x16 character, back-lit LCD display/keypad may be added. This optional keypad may be mounted remotely from the
MX control card. The remote LCD keypad has the same keys as the standard display with several additional keys including start and
stop keys for operation of the starter from the keypad. When the remote LCD keypad is connected, the local display is disabled.
3.2 Standard Keypad and Display
The LED display provides information on starter operation and programming. The 4-digit, 7-segment display shows starter meter
outputs and programming data. Special symbols provide further information about the starter operation (see the following section).

display.
To return to the default meter display either:
