Nowadays, the circuit control systems of the channel gates generally include: operation button boxes, control boards, remote controllers, and detection and control circuits composed of some sensors. All of these have strong professional and technical characteristics. For some inexperienced channel gate maintenance personnel, there is a certain degree of difficulty. As an electronic product maintenance personnel, in addition to the relevant electronic component application knowledge and electronic circuit analysis capabilities, it is necessary to continuously summarize induction experience in practical work, and gradually increase their own logic analysis capabilities and maintenance skills.
The basic methods commonly used in maintenance can be summarized as follows: one ask, two see, three listen, four touch, and five tests. The following will be explained one by one for your reference.
One question: That is to ask, in communicating with customers, first ask the channel gate type, product name, damage reasons, failure phenomenon, and then detailed analysis based on this, in order to achieve a targeted, symptomatic remedy, detours. The main contents of the inquiry are: When was the damage, whether it was flooded, whether it had been struck, whether the voltage was too high, whether there was any change, whether it was operated improperly, whether it was struck by lightning, whether there was smoke, whether there was abnormal noise, and so on. Only after clarifying the reasons can we determine the next method of maintenance and the corresponding treatment measures. For lightning, flooding, smoking, burning insurance and other fault models, must not rush electricity test machine, otherwise it will cause the machine to suffer again, the failure to expand.
Second look: After observing, open the cover of the channel gate, you should carefully check whether there are components on the circuit board. Such as broken components, dark yellow hair, pin touch, loose components, connection errors. Some of our experienced maintenance personnel will accurately look at the suspicious parts according to the relevant information and fault phenomena provided by the user at this time, and find out where the faults are. Some poor contact failures can be determined by observing whether there is a spark in the dark part of the light.
Three-listening: that is, listening, because in the control system, most of the use of electromagnetic relays as a control device, so the relay contacts will produce a clear "trickle" sound. If there is no sound or abnormality, after confirming that the relay-driven electrical device has no fault, the relay may be judged to be defective.
Four touch: touch, in the process of repair channel gate, it is often touched (nasal sniffing) some elements after power. Such as voltage regulator ICs and other integrated devices, lightning protection guan, transformers, drive diodes, etc., in order to feel the temperature is normal, such as fast heat, high temperature, the circuit has no short circuit fault can determine the device is bad (Note: For high voltage components For components such as thyristor and high-voltage areas, they should be energized for a period of time and then quickly touched after power off. Do not touch them when they are powered on to avoid electric shocks.
Five test: Measure, refers to the universal table screwed to the appropriate gear, the channel gate control circuit for related measurements. The commonly used methods include measuring the voltage, measuring the resistance of the circuit, and measuring the current. This is a comprehensive logic analysis method that can be based on a variety of measurement data to identify the cause of the failure and damage the device.
