4.9 Remote LCD Keypad and Display
The MX
2
Sync Controller can be equipped with an optional 2x16 character, back-lit LCD display/keypad that is
mounted remotely from the control card. The remote keypad is NEMA 3R / IP65 when mounted directly on the
door of an enclosure with the correct gasket.
Like the standard keypad, the remote LCD keypad has the same basic functions with enhancements that allow
using plain text instead of codes and a menu structure instead of a straight line of parameters.
Additional keys have been added, such as [MENU], [STOP], and a [LEFT] arrow for moving the cursor around
in the LCD display. Status indicators provide additional information for controller operation.
NOTE: The Start push button does not operate with a synchronous controller.

4.10 Description of the LEDs on the Keypad
The keypad provides three LED indicators in addition to the 2x16 character display. The LEDs provide
controller status information.
NOTE: By default, the [STOP] key is always active, regardless of selected control source (Local Source
and Remote Source parameters). It may be disabled though using the Keypad Stop Disable (I/O
14) parameter. For more information refer to the Keypad Stop Disable (I/O 14) parameter on Page
80.
