e) 模块自检维护
本程序具有模块自检功用,当PLC呈现毛病时,本设备具有如下维护:
* PLC自确诊:当拓展模块呈现毛病时, 有“模块毛病”报警画面。
f) 功用实验功用
* 漏电实验:是运用继电器外接1K电阻完结的。
* 短路实验:模仿电流是“额外电流”与“短路倍数”的积送内存单元。
* 过载实验:为1.9Ie,动作时刻为60秒,由于动作时刻较长,为此在程序中设置了显现。
g) 毛病回忆功用:
设备能对近50次毛病进行回忆,并可别离报出十四种毛病,包含动作时刻和动作值。进入毛病回忆画面和在内进行上下翻页时具有人性化个性,改动了曩昔的车轱轳转办法。
h) 开机时刻回忆功用:
本设备能回忆“累计带电时刻”和“累计吸合时刻”
除了上面罗列的底子功用本馈电开关还有漏电电阻、电压、电流以及功率显现功用,瓦斯超限、高压据动、低压据动等功用。
