Installation and Wiring Guide
Correct installation is the foundation for ensuring stable operation of the RSG45. Please follow the steps below.
- Confirm that the power supply voltage matches the nameplate, and disconnect the power before wiring.
- Connect the sensor signal wires to the corresponding terminals, and note that the shielding layer should be grounded at one end.
- Use twisted-pair shielded cables for communication lines, away from power cables.
- Secure the instrument and ensure the front panel is sealed to prevent dust and moisture ingress.
Note: Before wiring, be sure to refer to the terminal definition diagram in the manual to avoid damaging the input module.
Operation and Configuration Points
Most configurations can be completed through the touchscreen or web interface. Common operations include:
- Channel settings: Select input type, range, unit, and filter time.
- Recording settings: Set recording interval, trigger mode, and storage path.
- Alarm settings: Configure alarm thresholds, delay, and output actions.
- Communication settings: Set IP address, Modbus register mapping, etc.
It is recommended to export and back up the configuration file via USB when using it for the first time, to facilitate batch copying.
Maintenance and Troubleshooting
The RSG45 is designed to be robust with low daily maintenance, but regular inspections can extend its lifespan.
- Clean the screen regularly using a soft cloth and neutral detergent.
- Check whether the wiring terminals are loose, especially in vibrating environments.
- If the display is abnormal, first check the power supply and fuse.
- If communication fails, confirm the IP address and protocol settings.
