By selecting a category and number before CLEAR or TAKE is pressed, a new output selection is entered in the output display.
When TAKE is pressed, the control panel will be assigned to control the new output bus.
Note: If the panel cannot be changed to the desired output, it may have been limited to certain outputs by the CP
Output Set used on the MPK Devices table. See page 5−112.
DIAG — CONTROL PANEL DIAGNOSTICS
Special control diagnostics can be defined by the system controller and executed at the control panel. The operator interaction
and panel displays will be determined by the actual diagnostic selected.
The operator presses the MENU mode selection push button, then the MORE key to display the control panel DIAGnostics
selection. The operator presses the DIAGnostics soft−key and the first group of options is displayed. The operator presses
the soft−key for the desired selection and then follows the instructions on the control panel display.
Upon completion of the selected diagnostic, the control panel returns to the DIAGnostic selection menu. The operator may
then select another diagnostic or press the CLEAR key until the panel returns to the default control panel mode.
Display Self−Test
The display self−test mode is used to check the proper operation of the vacuum fluorescent (VF) character display. When the
test mode is started, a pattern of all position display characters will be written to each character position.
The display self−test will continue until the operator presses the CLEAR or TAKE push buttons. The panel will then return
to the DIAGnostic selection menu. Pressing the CLEAR push button again, will return the panel to mode it was in before the
diagnostic menu was selected.
Keypad Self−Test
The keypad self−test mode is used to check the proper operation of control panel push buttons. When the test mode is started,
the display will show the definition of each control panel push button as it is pressed. This display will show the button name/
address and the currently defined panel function name.
The keypad self−test mode will continue until the operator presses the CLEAR or TAKE push buttons twice.
