f) LED Lights and Audible Alarm Safeties
The control board includes LED indicator lights, audible alarm safeties, and an output test
feature. The "POWER OK" LED indicates control voltage and will remain on unless a control
voltage problem occurs. The “POWER OK” LED flashes continuously when the bin is full
and DV energizes for a maximum of 5 minutes to drain the water tank.
At startup, a 5 second delay occurs to stabilize the circuit. LEDs 4 through 8 energize and
sequence from initial startup as listed in the table below. Note that the order of the LEDs
from the outer edge of the board is 5, 6, 8, 9, 4, 7. For more information, see "2.
