Installation and usage precautions

5.1 Installation specifications

-Before installation, it is necessary to confirm that the main control board model matches the equipment model completely. Check that the circuit board is not deformed, the pins are not bent or oxidized, the components are not detached or damaged, and the matching connectors and screws are complete.

-The installation location should be far away from high-power heating devices such as power modules and transformers, ensuring a distance of ≥ 10cm from surrounding components. The internal ventilation of the equipment should be good, and if necessary, a cooling fan should be installed to prevent high temperatures from affecting the performance of the board.

-When plugging or unplugging the board, the main power supply of the device should be cut off first, and an anti-static wristband should be worn to avoid damage to the integrated circuit on the board caused by human static electricity; When inserting, align with the slot guide rail, smoothly advance, ensure good contact of the connector, and prohibit forced insertion and removal.

-When wiring, it is necessary to strictly distinguish power, signal, and communication lines according to the wiring diagram. Power lines and signal lines should be wired separately, and communication lines should be shielded and grounded at one end to avoid electromagnetic interference causing abnormal data transmission.

5.2 Key points of use and maintenance

-Before the first power on, it is necessary to use a multimeter to check the input power voltage and polarity, confirm that they meet the requirements of DC 24V ± 15%, and avoid overvoltage or reverse connection that may damage the power circuit; After powering on, observe whether the onboard power indicator light (usually green) is constantly on. If not, report to the police for further action.

-When configuring parameters through debugging software, it is necessary to first backup the original parameters of the device, and after modification, perform parameter verification and solidification to avoid parameter errors that may cause abnormal device operation; Different operating modes require calling corresponding parameter groups to ensure that the parameters match the operating conditions.

-During operation, it is necessary to regularly check the onboard status indicator light. If the fault indicator light (usually red) lights up, the machine should be stopped immediately and the fault code should be read through debugging software. After investigating the cause of the fault, the device should be restarted to avoid the fault expanding.

-Regularly clean the interior of the equipment, with a focus on removing dust and debris from the surface of the main control board. During cleaning, power should be turned off and dry brushes or compressed air should be used. Wet cloths or liquid cleaning agents are prohibited to prevent short circuits on the circuit board.

-During equipment maintenance, it is necessary to first cut off the power supply and make safety signs. It is prohibited to plug in or unplug the main control board or modify the wiring while it is powered on; After replacing the main control board, it is necessary to re import the backup parameters and conduct functional testing to ensure that the device is running normally.
