The ACP-DJCS is designed to operate an aerobic treatment unit with a shaft aerator. This control panel will power one shaft aerator and one effluent pump. There is no timer to operate the aerator in this control. The aerator in this system will run continuously. There will be a 360 degree top mounted red light for alarm conditions and a pizo electric buzzer in the door of the enclosure.
The 20 Amp pump circuit breaker will supply a 120VAC single phase 1⁄2 HP or smaller pump. The pump operation is controlled by an Omron H3CRF8 repeat cycle timer. With this timer the pump can be operated from one second to 30 hours with independent run and rest time settings. This is helpful when wanting to move small volumes of water like in aerobic drip fields. The 10 Amp air compressor circuit breaker will power one residential sized shaft aerator continuously. The 10 Amp alarm circuit breaker will power the alarm circuit. The High Water alarm is designed to be used with a normally open float switch. When the high water float switch raises the red alarm light and buzzer will activate. This control uses a current switch to monitor aerator operation. The shaft aerators do not have air lines and rely on a spinning tee on the bottom of the motor shaft to draw air through the hollow motor shaft and out the tee. If the motor is disconnected from the power source, shuts off due to thermal overload, or the circuit breaker trips, the current switch will activate the alarm light and buzzer. This type of alarm is beneficial over just relying on the circuit breaker to trip which is found in most alarm systems on the market today. There are alarm test and buzzer silence switches mounted in the door of the enclosure.
The enclosure has a NEMA rating of 4X which provides protection from falling dirt, falling liquids, hose directed water and corrosive agents. The 10”x8”x4” enclosure is made of Polycarbonate and has a hinged lockable door with latches and included screws to secure the door if required. All electrical components are mounted inside the enclosure on an aluminum back plate.
