Simple troubleshooting method for crane remote control

Wireless remote controllers are used more and more in workshop cranes. They are basically standard equipment. They are often used in electric single-beam cranes, small-tonnage double-beam bridge cranes, single-beam gantry cranes, small-tonnage double-beam gantry cranes, Electric hoist and other lifting equipment. In the previous article, the editor introduced the safe operation procedures of the remote control. Today, the editor will introduce some common troubleshooting methods for the crane remote control.

Simple troubleshooting method for crane remote control

1. Confirm whether the battery power supply is normal.
2. Check whether the battery model and installation direction are correct.
3. Check the installation direction of the battery box.
4. Check the battery level of the crane remote control.
5. Check whether the connection between the battery box and the circuit board is open.
6. Confirm whether the micro-processing control unit is faulty.

The transmitter LED light is normal, but the receiver does not respond at all

1. Confirm that the power input of the receiver is normal.
2. Check whether the AC power fuse and DC power fuse are blown. If necessary, turn off the main power supply and replace it with a spare fuse.
3. Confirm that the wiring between the “receiving high frequency” module and the “relay” module is normal.
4. Confirm whether the output fuse of the relay is blown, and replace it with a spare fuse if necessary.
5. Confirm that the S/N codes and CH channel numbers of the receiver and transmitter are consistent.
6. Check whether the quartz crystal of the transmitter is broken or falling off.

The LED light of the transmitter is always on, and the operation button has no response

1. Do not press the “Start” button, just press the “Up, Down” and other action keys. The transmitter should flash red quickly to indicate an error in the startup mode. If not, it means that the microprocessor control unit is faulty, or the power supply wiring is abnormal.
2. According to the normal start-up procedure, the power indicator light is red, and the magnetic key cannot be started up or removed: the magnet is off or the magnetron on the circuit board is broken, install the magnet or replace the magnetron, the emergency method can be directly to the magnet The two ends of the control tube are short-circuited.
3. It may be that the remote control of the crane is stuck, open the back cover to remove the battery, and then reinstall it to solve the problem.

Individual buttons of the crane remote control do not work

1. Confirm whether the output fuse of the relay is blown, and replace it with a spare fuse if necessary.
2. Confirm whether the original remote control system is working normally. If it is normal, look for the original maintenance of the machine.
