During Local Flash Status mode, the Auxiliary Display Unit (ADU) will display the active
field signals. This can be helpful to verify that flash mode is active on all outputs
appropriately. Note that a short time delay will be introduced to the ADU display in this
mode.
4.1.10 CLEARANCE INDICATOR
A red CLEARANCE indicator will illuminate when the CMUip-2212 is in FSA as a result of a
Yellow Clearance or Yellow Plus Red Clearance fault. See section 2.7 and 2.8.
4.1.11 FIELD CHECK INDICATOR
A red FIELD CHECK indicator will illuminate when the CMUip-2212 is in FSA as a result of
a Field Check Mode fault. The indicator will flash at a 2Hz rate when the CMUip-2212 is in
FSA with Field Check Status as a result of Conflict, Lack of Signal, or Multiple fault. See
section 2.13.
4.1.12 SB #1 ERROR INDICATOR
A red SB #1 ERROR indicator will illuminate when the CMUip-2212 is in FSA as a result of
a Serial Bus #1 fault. See section 2.3.1. The SB #1 ERROR indicator will pulse at a 2 Hz
rate when the SERIAL BUS #1 DISABLE input is True. See section 3.7.
4.1.13 SB #3 ERROR INDICATOR
A red SB #3 ERROR indicator will illuminate when the CMUip-2212 is in FSA as a result of
a Serial Bus #3 fault. See section 2.3.2.
4.1.14 DIAGNOSTIC INDICATOR
A red DIAGNOSTIC indicator will illuminate when the CMUip-2212 is in FSA as a result of a
Diagnostic fault. See section 2.14.
The DIAGNOSTIC indicator will flash at a 4 Hz rate if the Datakey is not present and a FSA
state does not exist. See section 2.14.3.
4.1.15 SB #1 RX INDICATOR
A yellow SB #1 RX indicator will pulse On each time the CMUip-2212 correctly receives a
frame on Serial Bus #1.
4.1.16 SB #3 RX INDICATOR
A yellow SB #3 RX indicator will pulse On each time the CMUip-2212 correctly receives a
frame on Serial Bus #3.
4.2 RESET BUTTON
Depressing the RESET button resets the CMUip-2212 from the FSA condition after it has
been triggered by a fault. When the RESET button is depressed all front panel indicators
will be illuminated for 500 msec and the OUTPUT relay energized. Continuously
depressing the Reset button will not affect CMUip-2212 operation.
4.3 DATAKEY
The front panel mounted Keycepticle
tm
is used to receive the Datakey serial memory
device. To install a Datakey, insert the key and rotate clockwise 90 degrees to the vertical
orientation. When a Datakey is installed while the power is applied to the CMU-2212, the
CMUip-2212 will load and verify the parameters and begin using the new configuration
immediately.
