30. Engineer Training XL1500 Electronics Confidential 30 Sensor Control Board (Cont.) LED CONFIGURATION  There are 16 Green LEDs on the Board, and these are connected on a serial configuration from left to right.  If there is an Overflow in a specific partition of a specific tank, the LED will be turned Off from the LED that has the overflow as well as all the LEDs to the right from this one.  This means that the first LED that’s OFF from Left to Right, indicates the Tank and Partition with the overflow.  There are 4 LEDs for each Color, 2 for each tank and 1 for each partition.
