- Verify Installation: Double-check all connections and mounting to ensure stability and correct wiring.
- Restore Power: Once installation is complete and verified, restore power to the system.
- System Check: Monitor the system's display or control panel to confirm that the new sensor is recognized and providing accurate temperature and humidity readings.
For detailed wiring diagrams or specific system configurations, consult your Liebert system's service manual.
6. Operation
The SupplyMount 181464G7S T/H Sensor Assembly operates passively by providing real-time temperature and humidity data to the connected Liebert control system. Its operation is integrated with the overall system's environmental monitoring and control functions.
- Data Acquisition: The sensor continuously measures ambient temperature and humidity.
- Signal Transmission: These measurements are converted into electrical signals and transmitted to the Liebert system's controller.
- System Response: The Liebert system uses this data to regulate cooling, heating, and dehumidification processes to maintain desired environmental conditions.
No direct user interaction is required with the sensor itself once installed. All operational adjustments and monitoring are performed through the Liebert system's interface.
7. Maintenance
The 181464G7S T/H Sensor Assembly is designed for low maintenance. However, periodic checks can help ensure optimal performance:
- Visual Inspection: Annually, or as part of routine system maintenance, visually inspect the sensor and its wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: If dust or debris accumulates on the sensor housing, gently clean it with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
- Calibration Check: While the sensor is factory-calibrated, if you suspect inaccurate readings, consult your Liebert system's service manual for procedures on sensor calibration or verification.
8. Troubleshooting
If you encounter issues with the T/H sensor, consider the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No temperature/humidity readings | Loose or incorrect wiring; Sensor failure; System controller issue. |
|
| Inaccurate readings | Sensor obstruction; Environmental interference; Sensor drift. |
|
| Intermittent readings | Loose connection; Electrical interference. |
|
If troubleshooting steps do not resolve the issue, contact a qualified service technician or SupplyMount customer support.
