We use a new water pump motor automatic control system to control the water pump motor. This system contains one receiver, two remote controllers and two mini water level sensors. There are two operation methods. One is automatically controlling motor by water level sensor. Another one is remotely controlling motor by rf remote control.
The first and main method is to control water pump motor automatically by two mini water level sensors. Let’s show you how it works in detail.
First off all; put the water level sensor 1 downwards to the low water level. Put the water level sensor 2 upwards to the high water level.
Two wires of the water level sensor 1 are connected to wire 1 and wire 3 of wireless remote CB-2N-2.
Two wires of the water level sensor 2 are connected to wire 2 and wire 3 of wireless remote CB-2N-2.
The water pump motor is connected to normally open contacts (A&B) on rf receiver S1PUA-AC220-ANT2. The power supply (AC 100~240V) is connected to contacts N&L, so it can supply power to the receiver. We also need it supply power to the motor, so the wiring picture should be as follows:
When water is on the low level, two wires of the water level sensor 1 are connected. The remote is triggered and it will send the signal “ON” to the receiver. After the receiver receives the signal, the water pump is activated to pump water into the tank.
When water reaches the high level, two wires of the water level sensor 2 are connected. The remote is triggered and it will send the signal “OFF” to the receiver. After the receiver receives the signal, the water pump stops pumping water.
The second operation method is to control water pump motor with remote controller CB-2, which is the supplement to the first one.
Motor wiring is the same as it in the first one method.
Press the big button on remote; it will transmit an rf signal “ON” to the receiver. After the receiver receives the signal, the water pump motor will be activated to work.
Press the small button on remote; it will transmit an rf signal “OFF” to the receiver. After the receiver receives the signal, the water pump motor will stop working.
