The power box can be configured for three power level settings. The power box outputs a single voltage of 9600 vdc on high and a lesser voltage at the lower settings. The backside has a pair contacts at center and two pairs of contacts off-center. The 9600 volts is present at the pair of center contacts. The two pairs of off-center contacts are connected to chassis ground.
The power box has internal diagnostics. In the normal operating mode, a fault is indicated when the three red LEDs flash. Specific detail on the fault can be obtained by entering the setup-mode. A table of the fault codes is shown on page 5 of the AccuClean Service Manual.
After disconnecting and reconnecting power, there is a 10 minute delay before power up. This can be bypassed by going
into and then out of the set-up mode.
