Precautions
(1) Installation precautions
Before installation, please ensure that the system is powered off to avoid electric shock accidents or module damage during installation.
Choose a suitable installation location to ensure that the module is installed in a well ventilated, dry, and vibration free area, avoiding installation in high temperature, humid, and strong electromagnetic interference environments to ensure normal heat dissipation and stable operation of the module.
Follow the installation instructions of the module for correct wiring, ensuring that the input signal line is firmly connected to avoid loosening or poor contact that may cause abnormal signal transmission. When wiring, pay attention to distinguishing the positive and negative poles of the input signal to avoid reverse connection.
When using guide rail installation, ensure that the guide rail is firmly installed and correctly clip the module into the guide rail; When using panel installation, use appropriate screws to secure the module to the panel to ensure a smooth installation.
(2) Precautions for use
Ensure that the voltage and current of the input signal are within the rated operating range of the module, avoid connecting voltage signals that are too high or too low, and prevent damage to the module. If there may be excessive voltage or current in the input signal, appropriate protective devices such as fuses, overvoltage protectors, etc. should be installed in the input circuit.
Avoid frequent plugging and unplugging of module wiring terminals to prevent loose or damaged terminals, which may affect signal transmission. If you need to replace the wiring, you should first disconnect the power supply before proceeding with the operation.
Regularly check the working status of the module, observe the display of the indicator lights, and ensure the normal operation of the module. If abnormal indicator lights or module malfunctions are found, the machine should be stopped and checked in a timely manner, and the troubleshooting guide should be followed for handling.
During the operation of the module, avoid severe vibrations or collisions to prevent damage to the electronic components inside the module.
(3) Maintenance precautions
Regularly clean the dust and dirt on the surface of the module, maintain its cleanliness, and prevent dust accumulation from affecting the module's heat dissipation and electrical performance. When cleaning, dry and soft tools should be used, and wet cloths or corrosive cleaning agents should be avoided.
Regularly check the wiring terminals of the module to ensure that the wiring is secure and free from looseness, oxidation, and other phenomena. If loose or oxidized terminals are found, they should be tightened or cleaned in a timely manner.
Regularly replace and upgrade modules based on their lifespan and usage to ensure system performance and reliability. When replacing a module, the configuration data of the module should be backed up first to ensure that the new module can work properly after installation.
