LED OFF= no UDI input activity. See Figure 5-
16 .
RTD RTD Board Status Red/Green ON RED = Fail state/board not recognized.
ON GREEN = Normal state. See Figure 5-17 .
RTD Range (8 LEDs – 1 per point) Red LED ON = RTD over-range or RTD under-
range condition. See
Figure 5-17 .
RTD Range (8 LEDs – 1 per point) Green LED ON = RTD in range. See Figure 5-17 .
LLAI LLAI Board Status Red/Green ON RED = Fail state/board not recognized.
ON GREEN = Normal state. See Figure 5-18 .
LLAI Range (12 LEDs – 1 per point) Red LED ON = LLAI over-range or LLAI under-
range condition. See
Figure 5-18 .
LLAI Range (12 LEDs – 1 per point) Green LED ON = LLAI in range. See Figure 5-18 .
