The CCR Display

The CCR display will show 4 lines of information at any given time.
The display communicates directly with the DCMU inside the panel.
The information on the screen can be scrolled through and will cycle around as if on a rolling drum.

Basic Functions on the Keypad

The OFF button will turn the CCR off from any brightness step in Local or Remote. 

The ON button will turn the CCR on to the most previous brightness step. There is an LED on the button that will illuminate when the CCR is on.

The LOCAL UP and LOCAL DOWN buttons change the brightness step of the CCR when it is in Local mode.
If LOCAL DOWN is pressed when the CCR is at Step B10 (3 step configuration) or B1 (5 step configuration), the CCR will turn off.

The REMOTE button engages or disengages the Remote Control option of the CCR. The LED in the button will illuminate if Remote is enabled. Pressing the button while already in remote will put the CCR back into Local mode.

The FAULT button has a red LED that will illuminate when a fault condition occurs. If a fault occurs, the CCR will turn off and the fault description will be displayed on the screen. Pressing the FAULT button will clear the fault code and force the CCR to attempt operation again. DO NOT continue to press the fault button to reset the CCR if the actual fault condition is not fixed. Doing so may cause damage to the CCR.

The WARNING button has a yellow LED that will illuminate when a warning condition occurs. Pressing the WARNING button will cycle through any concurrent warnings. The CCR will still operate even if there are warnings.
It is recommended to identify the cause of the warning and fix them as prolonged runtime with warning conditions may cause damage to the CCR.

The CONFIG button is used to access multiple screens and menus. If equipped, pressing the CONFIG button once will access the Megger Now function. To access the configuration menu, press the CONFIG button again. If IRMS/Megger functionality is not installed, pressing the CONFIG button once will access the configuration menu of the DCMU. Pressing the CONFIG button again will show the diagnostics menu, which among other information stores the most recent faults and warnings.

The UP and DOWN buttons are the buttons that navigate the screen. If on the main screen, the information will cycle through as if on a rolling drum. If navigating the menus, you will see an arrow-cursor on the left side of the screen. The UP and DOWN arrows control the cursor.

The DOT buttons are selector buttons. If applicable, a command will be displayed above the DOT buttons.
For example, when navigating the configuration menu, the left DOT button has the word Enter above it and the right DOT button has the word Exit above it. Pressing the corresponding button will execute the command.

Understanding the Menu Structure

The CCR configuration menu is set up in a nested folder setup, like a file cabinet or the files on your computer.
While navigating the menus the top line, in this case Config, and the bottom line, in this case the button commands, will remain fixed.
The middle lines will scroll when pressing the UP or DOWN buttons.
If there are more menu options, an arrow will be displayed on the top or bottom line.
A right-facing arrow acts as the selection cursor.
