ALTD-#ATU-2A Control Panel

Duplex Aerobic Drip

The ALTD-#ATU-2A is designed to operate Duplex 120 VAC pumps 1/2 HP or less using an Omron H3CR dosing timer and power 1 to 6 aerators. When ordering this series control you will need to replace the # with the number of aerators you want to power.

Two 20 Amp pump circuit breakers for each pump circuit. Pump Test switch mounted inside the enclosure will over ride the timer and low level float and run one pump. When the switch is released, the alternator will switch causing the second pump to run next.

There will be a 10 Amp compressor breaker for each aerator circuit.

A 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 comes with a latching high water alarm stock.

A standard 1 PSI pressure switch is included for each compressor. Anytime the pressure of any compressor system drops below 1 psi, the amber alarm light and buzzer will activate. In controls with more than 1 compressor, there will be a green led mounted below the pressure switch that will indicate which compressors are working correctly.

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.
