Installation and Wiring Guide
Installation Steps
- Confirm that the instrument model matches the on-site signal type.
- Embed the instrument into the control cabinet panel and secure it with the supplied clips.
- Connect the power and signal lines according to the terminal definitions in the manual.
- After checking that the wiring is correct, power on and observe whether the display is normal.
Wiring Precautions
- Use shielded cables, with the shield grounded at one end.
- Route power lines and signal lines separately to avoid interference.
- Ensure the supply voltage is within the rated range to prevent damage to the instrument.
- Relay outputs must not directly drive high-power loads; an intermediate relay is required.
Common Faults and Handling
| Symptom | Possible Cause | Solution |
|---|---|---|
| No display | Power not connected or voltage insufficient | Check power wiring and voltage |
| Large display fluctuation | Signal interference or poor grounding | Check shielding and grounding, stay away from interference sources |
| Abnormal output | Incorrect parameter settings or load mismatch | Restore factory settings, verify load |
Selection and Procurement Recommendations
When purchasing COS81E, please confirm the input signal type, output mode, power supply, and installation dimensions according to actual measurement requirements. If special ranges or communication protocols are required, it is recommended to confirm with the supplier in advance.
