產品詳情資料：

功能概述下表總結了MVME172LX VME嵌入式控制器的功能。微處理器60MHz MC68060或64MHZ MC68LC060處理器外形尺寸6U VMEbus內存4/8/16/32/64MB交錯，ECC保護DRAM或4/8/16MB奇偶保護DRAM 128KB SRAM，帶備用閃存一個Intel 28F016SA 2MB 8位閃存設備

1、檢查周邊情況——仔細檢查變頻器和周邊環境的通風及照明情況。要確保通風設備能夠正常運轉，照明設備能夠正常使用。

2、檢查內部電纜——打開變頻器櫃門，檢查內部電纜是否有損壞、電纜間的連接是否正確可靠、所有接地線是否牢固可靠、接地點是否有生銹問題。變頻器內的所有螺栓和螺母應該每半年緊固一次，確保連接可靠。

3、檢查所有電氣連接的緊固度——查看變頻器內所有回路是否有異常的放電痕跡，是否有怪味、變色、裂紋、破損等現象。檢查所有功率單元的光纖有無損壞或松動，是否每個都插緊。

4、測量變頻器絕緣——每次停機後長時間恢復運行，應用2500V的兆歐表對變頻器及旁通櫃的主回路進行絕緣測試，確保測試合格後方可起動。

5、認真查遺——每次維護變頻器後，要仔細檢查變頻器櫃內外有無遺漏的螺絲、彈簧片、螺栓及金屬導線等物品，防止小金屬物品在變頻器風機起動後被吸入內部，造成變頻器短路事故。

6、***清潔——用帶塑料吸嘴的吸塵器或空壓機等***清潔變頻器內外及配電室，***設備周圍無過量的塵埃，確保運行環境清潔。

7、啟動前檢查——特別是對電氣回路進行較大改動後，要檢查所有電氣連接是否正確、牢固，防止“反送電”事故的發生。對於供水係統進行的控制，歸根到底是為了滿足用戶對於流量的需求。在高峰時期需求量大，需能快速供水；低峰時應維持管壓。其***根本的控制對象是流量，壓力被用來做為控制流量大小的參變量。如果保持供水係統某處壓力的恒定，也就***該處的供水能力和用水流量處於平衡狀態，可滿足用戶的用水需求。

Summary of Features The following table summarizes the features of the MVME172LX VME embedded controller.Microprocessor 60MHz MC68060 or 64MHZ MC68LC060 processor Form factor 6U VMEbus Memory 4/8/16/32/64MB interleaved, ECC-protected DRAM or 4/8/16MB parityprotected DRAM 128KB SRAM with battery backup Flash memory One Intel 28F016SA 2MB 8-bit Flash device

1. Check the surrounding conditions - carefully check the ventilation and lighting conditions of the frequency converter and the surrounding environment. To ensure that ventilation equipment can operate normally and lighting equipment can be used normally.

2. Check internal cables - Open the door of the frequency converter cabinet and check if there is any damage to the internal cables, whether the connections between the cables are correct and reliable, whether all grounding wires are firm and reliable, and whether the grounding points are rusty. All bolts and nuts inside the frequency converter should be tightened every six months to ensure reliable connection.

3. Check the tightness of all electrical connections - check all circuits inside the frequency converter for any abnormal discharge marks, strange odors, discoloration, cracks, damages, etc. Check if the optical fibers of all power units are damaged or loose, and if each is securely inserted.

4. Measure the insulation of the frequency converter - After each shutdown, resume operation for a long time. Use a 2500V megohmmeter to conduct insulation testing on the main circuit of the frequency converter and bypass cabinet, and ensure that the test is qualified before starting.

5. Careful inspection - After each maintenance of the frequency converter, it is necessary to carefully check whether there are any missing screws, spring plates, bolts, and metal wires inside and outside the frequency converter cabinet to prevent small metal items from being sucked into the interior after the frequency converter fan starts, causing a short circuit accident of the frequency converter.

6. * * * Cleaning - Use a vacuum cleaner or air compressor with a plastic suction nozzle to clean the inside and outside of the frequency converter and the distribution room. There should be no excessive dust around the equipment to ensure a clean operating environment.

7. Pre startup inspection - especially after major changes are made to the electrical circuit, all electrical connections should be checked for correctness and firmness to prevent the occurrence of "reverse power transmission" accidents. The control of the water supply system is ultimately aimed at meeting the flow needs of users. During peak periods, there is a high demand for fast water supply; Maintain a certain pipe pressure during low peaks. The fundamental control object of * * * is the flow rate, and pressure is used as a parameter variable to control the flow rate. If the pressure at a certain point in the water supply system is kept constant, the water supply capacity and water flow at that point are in a balanced state, which can meet the water needs of users.
