Installation and Maintenance Points
Installation
- Fix the module using the DIN-rail method and ensure good grounding of the chassis.
- Check the voltage range before connecting the power supply.
- Use standard screws and tools to avoid over-tightening or loosening.
Wiring
- Digital input/output channels are isolated. It is recommended to use shielded cables and keep signal cables separate from power cables.
Commissioning
- After power-on, check the I/O status and communication connectivity through the built-in diagnostic page or upper computer software.
- Use the SOE function to verify the response time of inputs and outputs.
Maintenance
- Regularly check the power supply voltage stabilization and whether the heat sink is dusty.
- Perform an online self-test every six months and record the fault log.
- When replacing modules, use the same model to ensure redundancy consistency.
