: Place an object 5" to 7" (127 to 178 mm) away from the BC
sensor lens. If shut down cycle does not start, confirm BC controller green "LED 1"
LED turns off. If not, check for 4VDC at CB K4 pin #1 (R) to CB K4 pin #2 (BK).
If 1VDC is present, confirm object placement. If object placement is correct, replace
BC sensor and BC controller. If BC controller green "LED 1" LED turns off and CB
yellow "BC OPEN/CLOSED" LED does not turn on and 4VDC is present at CB K4
pin #1 (R) to CB K4 pin #2 (BK), replace CB. If CB yellow "BC OPEN/CLOSED" LED
turns on and shut down cycle does not start, see "II.B.1.4) 1-min. Fill Cycle."
