The overcurrent alarm in mineral water production line 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, inverter repair is very fast. Points: lightning in mineral water production line converter repair plant generally has lightning absorb 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 mineral water production line inverter repair analysis: the inverter again in 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 the day-to-day maintenance, mineral water production line 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.
