This manual is for the user to select and use motor protection device. Please read carefully before installation, using and parameters setting. If you have any questions, please connect with suppliers and do not disassemble or alter the internal structure by yourself. The user should be equipped with a certain knowledge of machinery and electricity.
Motor protection device is researched and developed to protect and control motor with high performance digital microprocessor technology, based on the research of similar products abroad and summary of MCC electrical system home.The motor protection device possess international advanced protection function, support professional way of motor control and provide accurate monitoring function, can run for a variety of motor control, monitoring, protection, interlock, measure, remote communication, remote communication, remote control, fault information management.The motor protection device is a kind of multi-functional protector, greatly improve the design and the production efficiency and reduces the user site debugging and maintenance cost,, so as to improve the scene of the scientific and effective protection of the production process, the measurement and control unit, which is protected by intellectual property and software copyright.
Motor protection device adopt modular design structure, with those advantages of small in size, compact structure, guide rail or the self-contained bolt installation, suitable for various kinds of stationary and drawer cabinet where can be installed directly to use.Apply to three-phase asynchronous motor and motor protection control, motor production device is the best ideal products for many fields such as chemical, petroleum, electric power, mining, coal, metallurgy, municipal, paper making, the nuclear industry involving three-phase motor protection.
Provide accurate measurement of three-phase current, three-phase voltage and operating data.
Provide the protection of overload current (flow), underload current(owe), locked-rotor, open phase, three-phase imbalance, overvoltage, undervoltage, short circuit, leakage, grounding, start timeout.
Provide the direct start of the motor, positive and negative start, star triangle start, lotus root step-down start and direct bypass start.
Provide R-S485 communication function, support custom protocol, Modbus communication protocol and DCS/PLS 4-20 MA analog signal output which is convenient for the user to focus on integration management of intelligent MCC, digital protector monitoring network communication.
Provide multiplex programmable input/output interface and interlock to satisfy all kinds of process and control requirements
Provide to improve software and hardware design, posses self-test, self-calibration, upgrade function, high reliability and stability.
Provide scientific and effective protection, monitoring at the scene reliably and timely.
Provide LCD widescreen with character parameters of motor protection, monitoring and data.
Provide built-in CPU to monitor motor the condition of motor at work in the real-time.
Provide start-stop, control, operation, monitoring, protection integration and CPU. Field layer and control layer of communication adopt bussing technique.
