E2 Economy Control Panel

The E2 is designed to operate a residential aerobic treatment unit.  This control panel will power one rotary or linear air compressor and one effluent pump.  The E1 control will monitor the water level and system air pressure. There will be a 360 degree top mounted red light and piezoelectric buzzer in the door of the enclosure.

The 20 Amp pump circuit breaker will supply a 120VAC single phase ½ 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 operation where you only want the pump to operate during certain hours.

The 10 Amp air compressor circuit breaker will power one residential sized 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 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 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 aluminium back plate.
