Transmitter: The transmitter is portable, small in size, light in weight and easy to operate. The operation method is divided into two types: button type and suitable type. The button type is suitable for small cranes with simple roads. The shape is suitable for all kinds of cranes. The power supply is a rechargeable battery, which is resistant to impact and water. It is dust-proof, oil-resistant, small in size, and heavy in weight. The device consists of a device that is equipped with a CPU, a safety circuit, and an electrical switch. After receiving the algae instruction, after the expansion, demodulation, decoding and fee generation, the control signal is generated, and the corresponding organization of the crane is controlled.Minhang organization: Minhang organizes the electric device and the contactor, and controls the corresponding operation of the crane.
When the emergency parking function is used for mis-control or abnormal movement of the crane, the operator uses the emergency stop switch to block the power supply on the crane, and sends a running command. The emergency stop switch cannot be reset actively. After the parking is urgent, the rules must be executed to start the operation from the beginning.
Zero maintenance zero maintenance should be based on 2 points requirements: a pre-zero maintenance. Before the night, all the grip handles are required to send the algae in the zero position. In the second secret, the maintenance of the zero-voltage maintenance accidental power failure, the crane smasher should stop the operation. After the rehabilitation power supply, the if controller must be connected to the total power supply of the crane according to the normal operation procedure. When the power supply voltage is too low, the transmitter shall announce the suspension of the operation command after the visual inspection function. When the safety interlocking crane is lifted and the operation of the cart or the trolley is reversed, the control loop that blocks the opposite direction is operated. At the time, the original driver's room assistance method was retained. When planning a device, it is necessary to interlock the two operating methods. When the crane completes multiple points of control, the receiver should be set to interlock. It is guaranteed that only one I transmitter will be commanded at the same time.
The address code address code is unique. When the transmitter and the receiver are coded and decoded together, the controller can work normally. The controller is mainly used in the time division system digital transmission method capable of viewing the error code. The so-called digital transmission method is to distribute the letter of the vertical switch by time and transmit it in serial binary code. This method is suitable for transmitting multiple operation instructions, can view error codes, avoid malfunctions, and improve safety.
The aluminum key switch opens this switch to turn on the transmitter power. The key switch is raised and raised by the remote control.
