The ACP-PD-2A is designed to operate an aerobic treatment unit. This
control panel will power one rotary or linear air compressor and one
effluent pump. The control will monitor the water level and system air
pressure. There will be a 360 degree top mounted red light for high water
conditions and a 360 degree top mounted amber light for low air pressure
conditions. There is 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 aerobic drip
systems.. The 10 Amp air compressor circuit breaker will power one
rotary or linear air compressor 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. A standard 1 PSI
pressure switch is included in the control that will monitor the system
pressure. The Normally Closed contact of the switch should be used and
anytime the pressure of system drops below 1 psi, the amber alarm light
and buzzer will activate. 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.
