3.10.2 FAULT DIAGNOSTIC DISPLAY

Once the Signal Monitor has been triggered by a fault, the Green and Yellow field input status active at

the time of the current fault and the two previous faults may be displayed individually. This status is not

reset by an AC Line power interruption. To enter this display mode remove the Program Card. The

sequence is as follows:

Reset Event PCA LED Fault Status LEDs Channel Status LEDs

--- #1 Single flash Current Fault Status (newest) Current channel status

#1 #1 Single flash (G) AC POWER LED flashes Green field status 1-16

#2 #1 Single flash (Y) VDC FAILED LED flashes Yellow field status 1-16

#3 #2 Double flash Event #2 Fault Status Event #2 channel status

#4 #2 Double flash (G) AC POWER LED flashes Green field status 1-16

#5 #2 Double flash (Y) VDC FAILED LED flashes Yellow field status 1-16

#6 #3 Triple flash Event #3 Fault Status (oldest) Event #3 channel status

#7 #3 Triple flash (G) AC POWER LED flashes Green field status 1-16

#8 #3 Triple flash (Y) VDC FAILED LED flashes Yellow field status 1-16

To enter this display mode remove the Program Card. Depressing the Reset button advances the

display mode from the normal mode to the Green field input display. The (G) AC POWER LED will

pulse ON once per second to indicate this mode. The channel display LEDs will show the Green

channels active at the time of the fault. The PCA LED will pulse once per second to indicate the current

fault (#1, newest).

Depressing the Reset button again advances the display mode from the Green display mode to the

Yellow field input display. The (Y) VDC FAIL LED will pulse ON once per second to indicate this mode.

The channel display LEDs will show the Yellow channels active at the time of the fault.

Depressing the Reset button again advances the display mode from the Yellow display mode (of fault

#1) to the fault display mode for fault #2. The PCA LED will pulse twice per second to indicate the

previous fault (#2). Additional button closures will cycle through the colors for fault #2 and fault #3

(oldest). After the Yellow display for fault #3, the display will return to fault #1.

To exit this display mode, replace the Program Card. If the Program Card is removed while the Signal

Monitor has not been triggered by a fault, the fault status display mode will show the Green and Yellow

channels active when the Program Card was removed. If a PCA fault is displayed during the review,

the PCA LED will not flash during the Fault Status display step to indicate the fault number.
