Audio Electric Hoist Controller

In the stage mechanical system, the audio electric hoist controller serves as an important link between operators and audio electric hoists. It not only meets the flexibility requirements for the spatial arrangement of audio equipment but also provides technical guarantees for the hoisting operations of audio equipment through reliable control logic and safety protection mechanisms.

Operators should fully familiarize themselves with the basic principles, structure and operation methods of the audio electric hoist controller. This includes, but is not limited to, clarifying the rated voltage, rated current and control mode of the controller (such as relay control, PLC control, etc.), and mastering the specific functions corresponding to the buttons or knobs - for example, the trigger logic of the up/down buttons, the range of the speed adjustment knob (such as 0-50Hz frequency conversion adjustment), the mechanical interlock structure of the emergency stop button, etc. At the same time, it is necessary to learn about the adjustment limits of each component in detail through the technical manual: for instance, the adjustment threshold of the limit switch must not exceed the safe travel designed for the equipment, and the setting value of the current protection knob must not be lower than 1.1 times the rated current of the motor, etc.

If the operator is not familiar with a certain function of the equipment or the adjustment process, they must first consult the Operation and Maintenance Manual provided by the original factory, focus on studying the "adjustment parameter table" and "danger warning" chapters, or conduct face-to-face consultation with professional and technical personnel holding special equipment operation certificates. Only after clarifying the operation steps and potential risks can they start making adjustments. It is strictly forbidden to arbitrarily modify key parameters such as button sensitivity and knob damping based on experience without mastering the characteristics of the audio electric hoist controller equipment, so as to prevent abnormal operation of the equipment due to parameter mismatch, which may lead to accidents such as falling of hoisted heavy objects and burnout of the motor due to overload.
