About the Front Panel

Introduction
The D9040 Encoder is operated using controls and indicators on the front panel.
These include the numeric keypad, the Navigation/Selection keypad, the LCD, the
ALARM and POWER indicators. These are shown in the following
illustration:
Keypad
The numeric keypad is used to enter alphanumeric values. The MENU key sets the
software to the initial menu and the PREV key or the UP arrow key returns to the
previous menu. The PREV key can also be used to cancel a numeric entry at any
point during the entry sequence, and the LEFT Arrow key allows backspacing
through the entry.
LCD
The LCD provides information on the selections available at any menu level,
current settings for parameters, and certain status and alarm indications. This is a
2x40, backlit LCD panel. The top line may be status data or identifier information. It
can also display optional functions available for tuning operations. The bottom line
will show selections or parameter values available using the navigation/selection
keypad. The items are selected by pressing the SELECT (center key) or DOWN
Arrow key on the navigation/selection keypad.
