It is used in applications where less than six toilets (units) are discharged into a basin. The simplex unit is generally operated with a contactor to turn the pump ON and OFF. The contactor is activated by a single pole float switch. The float switch is a wide-angle differential switch that rises with the liquid level and turns the pump ON. As the liquid level decreases, the float lowers and turns the pump OFF. The switch differential is 120.. Sewage Pump Systems: Duplex System A duplex system is used in applications where more than six toilets (units) are discharged into a basin. However, each pump should be sized to handle the entire flow in case one pump fails. The duplex unit is controlled by a NEMA 1 control panel that has an automatic alternator, run lights, hand-off-auto switches, and an alarm bell. The duplex control panel is supplied with three float switches. The floats are to be positioned so that the lower float turns the pumps OFF. The second float alternates turning first one pump ON and then the other pump ON. The third float will turn BOTH pumps ON in case one pump cannot handle the flow. The third float will also sound the alarm (which remains on until the system is reset). Functionally, the liquid in the basin rises and trips the first float, but the pumps do not turn ON. As the liquid level rises, it trips the second float, activating one of the pumps. Once the liquid level recedes and no longer trips the second float, the pump will turn OFF. If the second float is tripped again, the other pump will turn ON. If for some reason the liquid level increases past the second float and trips the third float, both pumps turn ON and trips the alarm. Under normal circumstances, the first pump will handle the flow after the second float is tripped. In those cases, the liquid level will recede until it drops the lower float. This action turns the pump OFF. The next time that the liquid level rises, the other pump turns ON. This alternates the pumps; this prevents lockup and extends the lifer of both pumps. Available Controls For 115 volt only, a wide angle float switch can be supplied with a plug-thru series plug. For 230 volt Simplex units, a NEMA 1 Simplex Controller with a hand-off-auto switch and run light can be supplied. This is supplied with a wide-angle switch for automatic operation. For 230 volt Duplex units, a NEMA 1 control panel can be supplied with a hand-off-auto switches, run lights, pump alternator, and an alarm bell. This is supplied with a three float switch system for automatic operation. Figure 1 - Simplex System Figure 2 - Duplex System Installation Always disconnect the power source before attempting to install, service, relocate or maintain the pump. Never touch sump pump, pump motor, water or discharge piping when pump is connected to electrical power. Never handle a pump or pump motor with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur. Some models of this product include a grounded plug for quick installation anywhere a grounded outlet is accessible. Some models must be incorporated into the building’s electrical system. Models without plugs must be connected to a grounded circuit. The circuit should be equipped with a ground fault interrupter device. All models without plug-in power cords systems must be installed by...
