SHENZHEN FLYING INDUSTRY DEVELOPMENT CO.,LTD
Triggering method: When wire 1 and wire 3 are connected, it will send wireless signal "ON". When wire 2 and wire 3 are connected, it will send
wireless signal "OFF".
Channel / Button: 2
Button Symbol: A, B
Operating Voltage: 9V (1 x 6F22-9V battery, can be used for a week; or 1 x 9V Rechargeable Lithium Battery, can be used for two weeks. If you
want a longer working time, please use a 9V power adapter, or use our solar power supply system.)
Working Current: 30mA
Operating Frequency: 315MHz
Modulation Mode: ASK
Transmitting Distance: 1000m / 3000ft (theoretically)
With waterproof case and external antenna.
With power switch on the side.
Operating Temperature: -20°C to +70°C
Unit Size: 135mm x 42mm x 25mm
Water Level Sensor:
Body Material: PP
Float Material: PP
Operating Temperature: -10°C to +85°C
Maximum Voltage: DC 100V
Maximum Current: 0.5A
Maximum Power: 10W
Working Range:
The maximum working distance can reach 1000M in an open ground.
The maximum working distance is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it
will be hindered by trees, walls or other constructions, and will be interfered by other wireless signals. Therefore, the actual distance may not reach
this maximum working distance.
Usage:
1. Installation:
1) Put the water level sensor 1 downwards and install at the low water level position in the tank; Put the water level sensor 2 upwards and install at
the high water level position in the tank.
2) Connect the water level sensor 1 to wire 1 and wire 3 of transmitter CB-2N-2.
3) Connect the water level sensor 2 to wire 2 and wire 3 of transmitter CB-2N-2.
4) Connect the live wire of AC power supply to the receiver's terminal "L / +", and connect the neutral wire of AC power supply to the receiver's
terminal "N / -".
5) Connect the live wire of AC power supply to the receiver's terminal B, connect one side of the pump to the terminal C, and connect another side
of the pump to the neutral wire of AC power supply.
2. Operation:
1) Control pump by transmitter CB-2:
Press button A of the transmitter CB-2, the relay of receiver is activated, and the pump is turned on.
Press button B of the transmitter CB-2, the relay of receiver is deactivated, and the pump is turned off.
2) Automatically control pump by transmitter CB-2N-2 & Water Level Sensors:
When the water reaches the low water level, two wires of the water level sensor 1 is connected, the transmitter CB-2N-2 automatically emits a
wireless signal "ON", which is equivalent to the function of the button A on the transmitter. When the receiver receives this wireless signal, it will turn
on the pump motor to pump water into the tank.
When the water reaches the high water level, two wires of the water level sensor 2 is connected, the transmitter CB-2N-2 automatically emits a
wireless signal "OFF", which is equivalent to the function of the button B on the transmitter. When the receiver receives this wireless signal, it will
turn off the pump motor to stop pumping water.
You also can press button A or button B on the transmitter to turn on / off the pump.
How to pair the transmitter to the receiver:
1) Press the learning button of receiver; signal LED on the receiver is turned on, it means the receiver enters the learning status.
2) Press any one button on transmitter, if signal LED flashes quickly 15 times and turns off, it means learning is successful.
3) When receiver is in the learning status, press again the learning button, if signal LED turns off, it means learning process was discontinued.
4) The receiver can learn several transmitters with different codes.
Delete all transmitters:
We have learned transmitter to the receiver. If you don’t want the receiver to work with the transmitter, you can delete all codes of transmitters,
which are stored in the receiver.
Operation: Press and hold the learning button of receiver until signal LED flashes slowly, then release the button, signal LED remains flashing
slowly, it means all stored codes have been deleted successfully.
