CPU-ETH2 Controller Card
Card-Front Status LED
Pushing the CONTROLLER button on the control panel assigns the panel to operate the
CPU-ETH2 card itself. The STATUS LED on the CPU-ETH2 card flashes yellow to show that it is
selected for control.
The local control panel displays a menu that can be navigated using the four pushbuttons
located beside the display.
The full menu is shown beginning on
The functionality of the four pushbuttons is as follows:
[+] [–]
Move up and down the menu when a parameter name is shown
Change to the next or previous value when a variable value is shown and
change has been enabled using the [SEL] button
[SEL]
Gives access to the next menu level. When a parameter value is shown, pushing
this button once enables modification of the value using the [+] and [–] buttons;
a second push confirms the new value
[ESC]
Cancels the effect of parameter value changes that have not been confirmed;
pushing [ESC] causes the parameter to revert to its former value.
Pushing [ESC] moves the user back up to the previous menu level. At the main
menu, [ESC] does
not
exit the menu system. To exit, re-push the [CONTROLLER]
button.
If no controls are operated for 30 seconds, the controller reverts to its normal operating
mode, and the STATUS LED ceases flashing yellow and reverts to its normal operating
status.
Card-Front Status LED
The status LED is located on the front card-edge of the controller module, and is visible
through the front access door of the Densité 3+ FR1 frame. This multi-color LED indicates
module status by color, and by flashing/steady illumination, according to the chart below.
The chart also indicates fault reporting for this card on the DENSITÉ frame’s serial and GPI
interfaces.
The table shows how the various error conditions are flagged on the CPU-ETH2 status LED.
Alarm/Status
Priority LED
Power supply failure
1
FLASHING RED
Fan failure
1
FLASHING RED
Internal error
2
RED
Normal (no errors)
GREEN
LOCAL CONTROL SELECTED
FLASHING YELLOW
The status LED can display only one alarm/status, so it displays only the highest priority. For
example, if there is an internal error, it should display RED. But if at the same time the
chassis fan has failed, then the LED will display FLASHING RED.
Be aware that a high priority alarm can mask a lower priority one.
