? ? 標(biāo)準(zhǔn)機(jī)柜，針對(duì)造紙廠紙機(jī)的現(xiàn)場工藝情況，現(xiàn)場遠(yuǎn)程控制站的機(jī)柜是為工廠的惡劣環(huán)境由德國設(shè)計(jì)和制造的進(jìn)口品牌機(jī)柜，IP等級(jí)為55級(jí)的。主控單元、電源模塊、I/O模塊都牢固地安裝在內(nèi)，現(xiàn)場儀表信號(hào)線通過機(jī)柜底部的通道進(jìn)入機(jī)柜，直接接到I/O模塊的端子上。

n order to improve the effectiveness, accuracy and flexibility of process control, Ge provides you with an advanced mv6 series air-cooled medium voltage inverter for efficient motor control. Based on our rich industry experience, mv6 series inverter provides a flexible and effective way for many industry applications to realize low-cost operation by adopting a simple power module architecture. Mv6 series frequency converter is easy to install and maintain, saves space in the electrical room, has high availability, and has all the key factors to improve control performance and process effectiveness.
All mv6 series frequency converters are equipped with visorconnect, which is a remote equipment monitoring system. When necessary, it can be connected to ge experts through this system to obtain real-time service support and prevent unplanned downtime.Mv6 is one of Ge medium voltage inverter series products. Ge medium voltage inverter series provides a wide power range under a variety of voltages, covering various industrial applications. The field side circuit of the ic2alg266 power failure reports the loss, and also reports the open circuit fault of the wire in the mode of 4-2mA for each channel. When a / D conversion failure is detected, the module will report a hardware failure. The module detects this fault by applying known and verifying the expected results to the A / D conversion path. If it occurs three times in a row, the scan stops, the OK led goes out, and a hardware fault is reported. To clear this fault, re energize the module or replace it.
