ACP-PC-2A Control Panel

The ACP-PC-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 a Grasslin Pin Timer.
With this timer the pump can be operated on 15 minute intervals at any
time of the day. This type of system is used mainly for night time aerobic
spray operation where you only want the pump to operate during certain
hours. 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.
