1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is in normal operation, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in operation conditions, and do the corresponding recording operations; When repairing the inverter, check whether the voltage value and current value exceed the allowable ...

In daily work, the combination of circuit breaker, contactor and thermal relay is the most common combination of motor power supply circuit, and the circuit breaker is generally the short-circuit instantaneous action of magnetic maintenance, the contactor realizes relay logic control, and the thermal relay overload maintenance. The parameter selection method of these three kinds of gas parts is as follows: ( ...

1. OLF is motor overload. Possible reasons: 1. Triggered by high motor current. 2. The value of the [cold stator resistance] (rSC) parameter is wrong. Corrective measures: 1. Check the [Motor Thermal Current] (ItH) setting of the motor thermal maintenance function and check the motor load. Wait...

RM4 Series Control Relay (Three-phase Power Control) RM4 series voltage steerable relays RM4 current operated relay RM4 level control relay RM17 three-phase power controller RM35 3-phase power control relay RM17 Voltage Steerable Relay ...

1. Check whether the appearance of the inverter is in good condition, including whether the indicator light is running normally, whether the task control function of the operation panel is complete, and carefully observe the appearance of the inverter in the operating state, and do the corresponding recording work; When repairing the inverter, check whether the voltage value and current value exceed the allowable ...

Line leakage detection method, leakage check method summary, if a closing, leakage switch will trip, this kind of front leakage, check the method is as follows: 1. Disconnect all the separation gates, close the main gate, close the separation gates one by one, and close them to ...

The type of sensor output signal Sensors are commonly used detection devices that convert perceived information into electrical signal outputs, and are used in a variety of applications. What can be divided into the output signal mode of the sensor ...

1. Save capital contribution Focus on central function (true color LCD, serial communication interface, USB connection, Ethernet interface, etc.) 2. Save space Compact structure planning, only 38mm thick The fuselage is reserved for communication wiring ...

A kind of pressure reducing valve in instrumentation refers to a kind of equipment used to control the pressure value. Pressure reducing valves are usually used in water-related categories, because from the perspective of the transmission medium, the transmission medium of the equipment is mainly water, but we all know that water is a thing that will ...

1. Selection of detection diode Point-contact germanium diodes are generally used for detection diodes, such as 2AP series. When selecting, the detection diode with high operating frequency, small reverse current and large forward current should be selected according to the specific requirements of the circuit. Although the detection and rectification of ...

Schneider Electric has announced the launch of its Pacific Foundation, which will provide financial and advisory support to charitable foundations in the Pacific region to address fundamental human rights issues of access to energy. Four foundations were selected as the Foundation's initial recipients.

There are three main differences, namely: different applications, different products, and different characteristics. 1. The application situation is different: the programmable manipulator produced by Siemens in Germany is also widely used in China.

(1) If the signal is controlled on a counter, first look at the logic that controls the reset, then the counter signal. Follow steps 2 to 5 above. (2) If Schneider PLC aborts in some places where the output is encouraged, generally in the middle of the situation, then look for the next step ...

1. What is the difference between high-voltage inverter and low-voltage inverter? Frequency converters can be broadly divided into two categories: high-voltage frequency converters and low-voltage frequency converters. In terms of use, the applicable objects are different, and the high-voltage motor is the same from the principle of speed regulation. From the topology ...

First, it is a fan/pump load Second, the device itself has a power-saving function (software support) Third, we need to work for a long time The above are the three conditions that reflect the results of power saving. If it is said that the power frequency of the inverter is energy-saving without conditions, it is ...

The appearance of the instrument plays a very important role in the air separation equipment and gas purification process, and it is indispensable for the adjustment of the air separation process and the detection of product quality. Because there are different types of on-line profiles for monitoring targets in different gaseous media at each stage of the ASU process, the ...

The protection and viewing of inverters and soft starters is a useful means to prevent occasional equipment problems. In order to be useful for protection and inspection, inspection orders should be created to record and save the inherent characteristics of the equipment and the stability of the constituent parts, so as to prevent problems and problems that occur.

1. Aluminum alloy shell or steel plate welding, surface spraying; 2. Built-in inverters, circuit breakers, signal lights and other components produced by domestic or Schneider and other companies; 3. It mainly regulates ordinary three-phase by changing its output frequency ...
