2. Setup
2.1 Mounting the Sensor
The sensor can be mounted using the included mounting clip and hardware. Choose a location that accurately represents the temperature you wish to monitor, away from direct sunlight, heat sources, or drafts that could affect readings.
- Select a suitable mounting surface.
- Secure the mounting clip using the provided screws or other appropriate fasteners.
- Snap the sensor probe into the mounting clip. Ensure it is held firmly in place.
2.2 Wiring Instructions
Connect the sensor's 12-foot wire to the appropriate input terminals on your Sensaphone monitoring unit. Refer to your specific Sensaphone model's user manual for detailed wiring diagrams and terminal assignments.
- Ensure the Sensaphone unit is powered off before making any wiring connections.
- Connect the two wires from the FGD-0101 sensor to an available analog input terminal pair on your Sensaphone unit. The sensor is non-polarized, so the wire order does not matter.
- If extending the wire length, use 22 AWG (American Wire Gauge) or larger twisted-pair wire. For runs over 100 feet, consult the Sensaphone unit's manual for maximum allowable wire lengths and gauge requirements.
- Secure all connections to prevent accidental disconnections.
3. Operating
Once properly connected to a compatible Sensaphone monitoring system, the FGD-0101 sensor will continuously measure the ambient temperature. The Sensaphone unit will then interpret this data and provide readings, alerts, or logging capabilities as configured.
- Temperature Readings: The Sensaphone unit will display or report the temperature detected by the FGD-0101 sensor.
- Alarm Thresholds: Configure high and low temperature alarm thresholds within your Sensaphone unit's settings. If the temperature falls outside these set limits, the Sensaphone will trigger an alarm according to its programming (e.g., send an alert, activate a relay).
- Data Logging: Many Sensaphone models offer data logging capabilities, allowing you to track temperature trends over time.
Refer to your specific Sensaphone monitoring system's user manual for instructions on configuring temperature alarms, viewing readings, and managing data.
4. Maintenance
The Sensaphone Weatherproof Temperature Sensor is designed for minimal maintenance. However, periodic inspection can help ensure its continued accuracy and longevity.
- Cleaning: If the sensor probe becomes dirty, gently wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the sensor's wiring for any signs of damage, fraying, or loose connections. Ensure the sensor is securely mounted.
- Environmental Factors: While weatherproof, extreme environmental conditions (e.g., prolonged submersion, direct impact) should be avoided to prevent damage.
5. Troubleshooting
If you experience issues with your Sensaphone Weatherproof Temperature Sensor, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate temperature readings | Sensor exposed to direct sunlight, heat sources, or drafts; faulty wiring; sensor malfunction. | Relocate sensor to a more representative area. Check wiring connections. Test with another sensor if available. |
| No temperature reading / Sensor not detected | Loose or incorrect wiring; incompatible Sensaphone model; sensor damage. | Verify wiring connections and ensure they are secure. Confirm compatibility with your Sensaphone unit. Inspect sensor for visible damage. |
| Intermittent readings | Loose connections; electrical interference; damaged wire. | Check and secure all wiring connections. Ensure wiring is routed away from high-voltage cables. Inspect wire for damage. |
If problems persist after attempting these steps, contact Sensaphone technical support or your authorized dealer for further assistance.
