This wireless receiver is an double pole double throw switch, also referred to as DPDT switch. It and the transmitter form a receiver transmitter system. This system may be used in remote control crane or winch.
Use wireless RF double pole double throw switch to replace the original wired control handle of winch or crane. So that the operator to control the movement of the goods up, down, left and right in a safe and controllable position.
However, some types of cranes and winches are not suitable for use. Suitable for the following types of wired control handles.
Wireless control, easy to install.
Universal input: Support 110V AC (100V~120V) used in US, Canada, etc, and 220V AC (200V~240V) used in Germany, UK, France, etc.
Output type: DPDT. it can be used to operate both DC and AC crane or winch.
High Power: Each channel can work at maximum load current 30A.
The transmitter / remote can control the receiver from any place within a reliable working distance.
The wireless RF signal from the transmitter can pass through walls, floors, doors or windows, but it will lose some operating range.
The receiver only works with the selected transmitter which is matched to the receiver.
One or more transmitters / remotes can control several or onereceivers simultaneously.
Two or more receivers may be used in the same area.

This receiver can work with different transmitters. such as model CV-4-2 (500M), or CB-3-2 (1000M) etc.
With a transmitter (such as CV-4-2) to form a complete set, the maximum working distance can reach 500 meter 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.
If you want to have a further working range, you can install an external antenna to the receiver, and you also can use a powerful transmitter, such as transmitter CB-3-2.
Setting different control modes:
1) Setting Momentary mode: Only connect Jumper-1.
Press and hold button ▲ on remote: Connect terminals 1&3, and connect terminals 2&4, motor of the winch or crane rotates in positive direction, and goods moving upward;
Release button: disconnect terminals 1&3, and disconnect terminals 2&4, motor of the winch or crane stops.
Press and hold button ▼ on remote: Connect terminals 3&5, and connect terminals 4&6, motor of the winch or crane rotates in reversal direction, and goods moving downward;
Release button: disconnect terminals 3&5, and disconnect terminals 4&6, motor of the winch or crane stops.
2) Setting Interlocking mode: Disconnect Jumper-1 and Jumper-2.
Press button ▲ on remote: Connect terminals 1&3, and connect terminals 2&4, motor of the winch or crane rotates in positive direction, and goods moving upward;
Press button ■ on remote: Disconnect terminals 1&3, and disconnect terminals 2&4, motor of the winch or crane stops.
Press button ▼ on remote: Connect terminals 3&5, and connect terminals 4&6, motor of the winch or crane rotates in reversal direction, and goods moving downward;
Press button ■ on remote: Disconnect terminals 3&5, and disconnect terminals 4&6, motor of the winch or crane stops.
