e) 模塊自檢維護
本程序具有模塊自檢功用,當PLC呈現毛病時,本設備具有如下維護:
* PLC自確診:當拓展模塊呈現毛病時, 有“模塊毛病”報警畫面。
f) 功用實驗功用
* 漏電實驗:是運用繼電器外接1K電阻完結的。
* 短路實驗:模倣電流是“額外電流”與“短路倍數”的積送內存單元。
* 過載實驗:為1.9Ie,動作時刻為60秒,由於動作時刻較長,為此在程序中設置了顯現。
g) 毛病回憶功用:
設備能對近50次毛病進行回憶,並可別離報出十四種毛病,包含動作時刻和動作值。進入毛病回憶畫面和在內進行上下翻頁時具有人性化個性,改動了曩昔的車 轤轉辦法。
h) 開機時刻回憶功用:
本設備能回憶“累計帶電時刻”和“累計吸合時刻”
除了上面羅列的底子功用本饋電開關還有漏電電阻、電壓、電流以及功率顯現功用,瓦斯超限、高壓據動、低壓據動等功用。
