V. Operation Guide

Local Operation

• Boot and Initialization Process: After the device is powered on, the SR465-P5-HI-A20 relay will automatically start the self-check and initialization program. During this process, the LED indicators on the front panel will flash in a specific order to visually feedback the self-check progress to the operator. At the same time, the 40-character LCD display will simultaneously display detailed self-check information, including the detection results of the device hardware status and software version information. When the self-check process is successfully completed, the LCD display will automatically switch to the interface displaying the real-time operating parameters of the motor, such as the current three-phase current values and three-phase voltage values, so that the operator can master the operating status of the motor at the first time.
• Menu Operation Steps: If the operator needs to perform function settings, parameter adjustments, or information viewing on the device, they can press the eye-catching "Menu" button on the front panel, and the device will enter the main menu interface. The main menu interface is designed to be simple and clear, including several main function options such as "Settings", "Monitoring", and "Fault Records". The operator can quickly switch and select among the menu options by pressing the up and down direction keys on the front panel, and press the "Enter" key to enter the corresponding submenu when the desired function option is selected.
• Parameter Setting Method: In the "Settings" submenu, it is further subdivided into several special setting submenus such as "Motor Parameters", "Protection Settings", and "Communication Settings". For example, in the "Motor Parameters" submenu, the operator can accurately set the key parameters of the motor such as rated power, rated current, and rated voltage according to the specification model of the actually connected motor; in the "Protection Settings" submenu, the important protection parameters such as the action current multiple and action time delay of the overload protection function, and the action current threshold of the short-circuit protection function can be flexibly adjusted. When entering the parameter values, use the specially equipped digital keys on the front panel to operate, and after the input is completed, press the "Enter" key again, and the device will automatically save and confirm the set parameter values.
• Application of Monitoring Function: After entering the "Monitoring" menu, the operator can view multiple operating parameters of the motor in real time, including the real-time values of three-phase current, three-phase voltage, the current output power of the motor, and operating frequency and other key information. At the same time, the menu interface will also intuitively display the real-time operating status of the motor, such as whether the motor is in the running, stopped, or fault alarm state, etc., so that the operator can grasp the working conditions of the motor at any time and find potential problems in time.
• Method for Viewing Fault Records: When a fault occurs during the operation of the motor, the SR465-P5-HI-A20 device will automatically and timely record detailed fault information. The operator can view the specific type of fault, such as overload fault, short-circuit fault, undervoltage fault, etc.; the accurate time of the fault, accurate to the second level; and the values of various operating parameters of the motor at the moment of the fault, such as the current, voltage, power, etc., by entering the "Fault Records" menu. These detailed fault record information provide crucial clues for subsequent fault troubleshooting and analysis, helping technicians quickly locate the cause of the fault and formulate effective solutions.
• Method for Exiting the Operation: When the operator has completed all local operation tasks, they can press the "Exit" key on the front panel, and the device will gradually return to the upper-level menu interface. Continue to press the "Exit" key until the menu operation interface is completely exited and return to the main interface displaying the real-time operating parameters of the motor, at which time the device will continue to maintain the real-time monitoring and protection function of the motor's operating status.

Remote Operation

• Establishment of Communication Connection: Before performing remote operations, the primary task is to ensure that the communication line connection between the SR465-P5-HI-A20 device and the external automation system is accurate, and the communication parameter settings of both parties are completely consistent. Common communication connection methods include RS485 serial communication, Ethernet communication, etc. Taking RS485 communication as an example, it is necessary to carefully check whether the wiring polarity of the communication cable is correct to ensure a stable and reliable physical connection between the device and the automation system. At the same time, according to the actual connection situation, accurately set the corresponding communication parameters in the "Communication Settings" menu of the device and the communication parameter configuration interface of the automation system, such as the baud rate (which can be set according to actual needs, up to 19200), the communication address (used to uniquely identify the position of the device in the communication network), etc.
• Operation Process of Monitoring Software: After completing the communication connection and parameter setting, the operator needs to open the host computer monitoring software. In the device management interface of the monitoring software, find the device icon corresponding to the SR465-P5-HI-A20. The communication connection between the monitoring software and the device can be attempted by double-clicking the icon or by first selecting the device icon and then clicking the "Connect" button on the software interface. Once the connection is successful, the monitoring software interface will display various operating parameters, status information, etc. of the motor in real time, and the displayed content is basically the same as the information presented by the "Monitoring" function in the local operation interface of the device, which is convenient for remote operators to understand the operating situation of the motor in real time.
• Operation of Remote Parameter Setting: In the monitoring software, there is a special parameter setting interface for the SR465-P5-HI-A20 device. In this interface, the operator can perform remote setting operations on motor parameters, protection parameters, communication parameters, etc. The operation method is similar to the local menu setting method of the device. For example, when setting the motor rated current parameter, enter the accurate value in the corresponding parameter input box in the software interface, and then click the "Save" or "Apply" button to send the set parameter value to the device end. However, when performing remote parameter setting operations, the issue of operation authority management must be highly valued. Only personnel with corresponding operation authority can perform parameter modification operations to ensure the safety and accuracy of the entire system operation and avoid equipment failures or production accidents caused by misoperations.
• Key Points of Remote Control Operation: Some monitoring software with perfect functions also supports remote control operations on the motor, such as remotely starting the motor, stopping the motor operation, and controlling the forward and reverse rotation of the motor. In the monitoring software interface, there is usually a special motor control button area. The operator only needs to click the corresponding control button, such as the "Start" button, "Stop" button, "Forward" button, or "Reverse" button, etc., and the monitoring software will send the corresponding control command to the SR465-P5-HI-A20 device according to the preset communication protocol. After the device receives the control command, it will quickly execute the corresponding control action to achieve the remote control of the motor. However, during the remote control operation process, the operator must always pay attention to the actual operation status of the on-site equipment and the safety of the surrounding personnel to ensure the safety and reliability of the remote control operation and prevent equipment damage or personal injury and other accidents caused by improper remote control.
