Research on the working state of electronic equipment

Electronic fully automatic operation interface: on this interface, fully automatic start and stop buttons, equipment working state simulation display graphics and parameter value display of each process tank, such as: temperature value, concentration value, flow value, ultrasonic working state display lamp , Ultrasonic frequency value, etc. Process flow simulation interface: This interface simulates the whole process of the process flow, with corresponding parameter display and dynamic display in important positions. Fault alarm screen: when the device fails or a certain process parameter is abnormal, this screen will pop up automatically, the device sound and light alarm to reveal the operator's attention, at the same time display the fault status, text prompt fault description, and can automatically record the fault status, convenient The maintenance personnel analyzes the cause of the failure and automatically deletes the previous record when the storage area is full. Production report and process parameter printing interface: On this interface, you can print the production report and the historical records of the selected process parameters.

The single chip microcomputer program mainly includes the subroutine of ultrasonic generation, the subroutine of positive communication with PLC, the subroutine of ultrasonic feedback and adjustment, and the subroutine of interrupt service. The A port of the 8255 chip expanded in the single-chip microcomputer system receives the frequency signal of the PLC, and the B port receives the feedback signal of the frequency detection device. In order to prevent illegal personnel from invading the system and modifying process parameters, three levels of priority are set in the program. That is: (1) Engineer level; (2) Technician level; (3) Operator level. Each level corresponds to a different entry password, that is, a password input interface appears on the man-machine interface after the system is started. After three incorrect passwords are input, the system alarms and automatically shuts down. The operator-level authority is the lowest authority for selecting the process file and executing the operation.

Introduction of Inverter Filter

Rated currents: 6 to 2000A

Stud or terminal block optional (above 250A it is copper bar)

FT330/FT330T series are general purpose filters, suitable for most inverter brands

Could be customized according to the real interference of customer`s working field

Features of Inverter Output Filter

FT330 series is designed according to the frequency characteristics of interference generated by inverter when it works towards power grid or other digital equipment.

Three-stage filtering design, high impedance at broad frequency range due to special magnetic materials adopted.

Assure the smooth operation of other electronic devices in the vicinity, solve the interference problems of inverter;

FT330T series is specially designed according to the frequency characteristics of interference generated by inverter output when it works towards load;

Effectively solve abnormal conditions such as load heating and howling that are easy to occur during long-distance transmission of frequency inverters, and better effect can be achieved with reactors;

Effectively control the common mode interference along the cable to protect load and increase its service life;

Touch-safe terminal block versions are available to meet the high safety requirement of certain special applications;

Copper bar terminals applied for versions above 250A to keep pace with international standard, easy and safe connection;

Optional 520VAC/690VAC (and above) high voltage versions.
