Wiring: Connect to a 115/230VAC or 24VDC power supply, ensuring correct wiring and reliable grounding; Connect serial ports, Ethernet, USB and other interfaces to the corresponding devices to avoid mixing of strong and weak electrical lines;

Power-on and debugging: After powering on, the power indicator light will light up, and the system will start; After entering the operating system, install drivers and configuration software, configure communication parameters and I/O addresses, and test data acquisition and control output.

Daily maintenance

Regular cleaning: Every 3 months, after power-off, use a dry soft cloth to wipe the front panel, interfaces and ventilation holes, removing dust and oil; Do not use liquid cleaners to prevent them from penetrating the equipment interior;

Interface inspection: Regularly check if the serial ports, Ethernet, and USB interfaces are loose or oxidized, wipe the contacts with alcohol cotton swabs to avoid poor contact;

Storage maintenance: Regularly back up the system and important data, check the health status of SSD/hard drives, and avoid data loss;

Environmental inspection: Ensure that the working environment temperature and humidity are within the allowable range, avoid long-term high temperature and high humidity, and extend the equipment lifespan.

Common fault troubleshooting

System cannot start: Check if the power wiring is normal, if the power module is damaged, if the memory/storage is loose; Investigate the motherboard fault;

Communication interruption: Check if the communication line wiring is correct, if the interface is oxidized, if the communication parameters (baud rate, address, protocol) are consistent; Replace the communication line and retry;

Large data fluctuations: Check if the I/O wiring is firm, if there are strong interferences at the site; Confirm that the equipment is well grounded and is far away from heat sources such as frequency converters and motors;

System freeze: Check if it is overheated (clean the ventilation holes), if there is a conflict with the program, if the memory is insufficient; Restart the system or reinstall the software.
