The graphic LCD displays are organized around operating status screens and setup screens. The actual number of status screens will be related to the total number of end devices configured for the controller. In either screen set, ten (10) lines are visible at a time; with up and down arrow characters indicating more lines are available on the page. Also, for both screen sets, navigation between screens is accomplished by pressing the left or right arrow keys.

The C3-3 Display uses a different approach to enter values than previous Murphy controllers. Instead of holding in the arrow keys until the desired number is displayed, the Centurion display allows individual editing of each position of the desired number. This is accomplished by entering the Edit Mode and using the UP/DOWN arrow keys (1) to adjust the number above the blinking cursor (2) between 0 and 9. To edit another position, simply use the LEFT/RIGHT (3) arrow keys to move the cursor to that position (4) and repeat the edit process until the desired number is displayed.
In this way, values are “built” rather than “scrolled” through. Some digits may not be allowed to increment if it would result in exceeding range limits. Values which can be positive or negative will have a sign (±) to the left of the number. To change the sign value simply move the cursor to the sign using the LEFT arrow key and “toggle” between + and – using the U and DOWN arrow keys. If the range of the value will exceed range limits the sign may not be allowed to change. In this case, try reducing the numebr by decrementing the left most digit by one or more and attempt to change the sign again.
In some instances, a word rather than a value is represented in the Edit Mode. This works like the sign value as an ON/OFF or YES/NO prompt where the value is “toggled” between choices using the UP/DOWn arrow keys.
The value is not active in the controller until the ENTER key has been pressed to send the value to the controller.
Pressing the ESC key will discard any changes and keep the original value prior to entering the Edit Mode.
