Before configuring the V3 board, it must be powered up prior to setting any of the configuration switches. To see if the V3 board is powered, look the Yellow STATUS LED located near the center of the V3 board. It should be flashing. Also, ALL the configuration switches to the V3 board should be turned OFF prior to turning any of them ON. The direction for OFF is down towards the center of the board. An arrow pointing to the direction for OFF is printed on the left side of the configuration switches.
If the input mask was properly set then the Red and Blue LEDs should have been alternately flashing. This indicates that an Input Mask on the QwikSwap® V3 board has been successfully programmed. However, if the Red and Blue LEDs are not flashing, it means that there may be multiple redundant commands telling the blower to operate and you will need to repeat the process of setting the Input Mask as many times as necessary until the Red and Blue LED begin alternatively flashing and all the Green LEDs are off.
