可以為所有測(cè)量量設(shè)置報(bào)警條件。這些包括過(guò)電流，

欠電流、中性電流、電流不平衡、電壓不平衡、相位反轉(zhuǎn)，

過(guò)頻、欠頻、功率因數(shù)、開(kāi)關(guān)輸入等。報(bào)警信息包括

以簡(jiǎn)單易懂的英文格式顯示。PQM配備了一個(gè)使用Modbus或DNP 3.0的標(biāo)準(zhǔn)RS485端口

協(xié)議。這可用于集成過(guò)程、儀表和電氣

通過(guò)將PQM儀表連接到DCS來(lái)滿足工廠自動(dòng)化系統(tǒng)的要求

或SCADA系統(tǒng)。運(yùn)行EnerVista PQM Setup的PC可以更改系統(tǒng)設(shè)定點(diǎn)和

監(jiān)控值、狀態(tài)和報(bào)警。持續(xù)監(jiān)控最大限度地減少了過(guò)程停機(jī)時(shí)間

通過(guò)立即識(shí)別由于故障或增長(zhǎng)變化而導(dǎo)致的潛在問(wèn)題。四個(gè)隔離的4至20 mA（或0至1 mA，取決于安裝選項(xiàng)）模擬輸出

可更換多達(dá)八個(gè)傳感器。輸出可以分配給任何

PLC直接接口的測(cè)量參數(shù)。

Alarm conditions can be set up for all measured quantities. These include overcurrent,

undercurrent, neutral current, current unbalance, voltage unbalance, phase reversal,

overfrequency, underfrequency, power factor, switch inputs, etc. The alarm messages are

displayed in a simple and easy to understand English format.The PQM is equipped with one standard RS485 port utilizing the Modbus or DNP 3.0

protocols. This can be used to integrate process, instrumentation, and electrical

requirements in a plant automation system by connecting PQM meters together to a DCS

or SCADA system. A PC running EnerVista PQM Setup can change system setpoints and

monitor values, status, and alarms. Continuous monitoring minimizes process downtime

by immediately identifying potential problems due to faults or changes from growth.Four isolated 4 to 20 mA (or 0 to 1 mA depending on the installed option) analog outputs

are provided that can replace up to eight transducers. The outputs can be assigned to any

measured parameters for direct interface to a PLC.
