The overcurrent alarm vinegar equipment converter repair is more common, content economic electromechanical failure when handling this type of 'OC' error can be said to be handy, plus plenty of accessories, the inverter repair is very fast. In lightning protection in the vinegar equipment inverter maintenance points: Factory generally has lightning absorb the network, mainly to prevent the instant the lightning invasion, the inverter damage. But in practical work, especially in the case of power cord row hit introduced the inverter alone absorb network can not be content requirements. In lightning active region, the subject is particularly important if the power supply is a row hit into the line, installed into the line the inverter dedicated arrester (optional), or according to specifications from the inverter 20m distant embed pipe do The dedicated ground protection. If the power cable entry, you should do a good job of the lightning protection system of the control room, prevent lightning fleeing the destruction device. The practice shows that this method is basically able to effectively solve the lightning topic. The error failure ER08 vinegar equipment the converter repair analysis: the inverter thrown ER08 fault code indicates that the drive is in undervoltage fault state. Main reasons the input power is too low or the lack of phase, the the inverter internal voltage detection circuit is abnormal, the main circuit of the inverter circuit is abnormal. Universal the inverter voltage input range of three phase 320V ~~ 460V. When the inverter in the practical application of full load operation, undervoltage protection may float to the surface and the input voltage drops below 340V, then progress grid input voltage or drive derating;, if the input voltage is normal, the inverter is running but thrown the ER08 fault, the inverter can be judged as an internal fault. Encountered in day-to-day maintenance of, vinegar equipment converter repair will not only overcurrent error will encounter other types of failure, if not solve the problem, you can contact Yung economic mechanical and electrical engineers for technical assistance.
