2. Safety Information

Please read and understand all safety instructions before installing or operating the device. Failure to follow these instructions may result in property damage, injury, or death.

• Electrical Safety: Installation and wiring must be performed by qualified personnel in accordance with all local and national electrical codes. Ensure power is disconnected before any wiring or maintenance.
• Environmental Conditions: The sensor is designed for outdoor use. However, avoid installing it in locations subject to extreme physical impact or direct, prolonged submersion in water.
• Handling: Handle the device with care. Do not drop or subject it to excessive force.
• Modifications: Do not attempt to modify or repair the device. Unauthorized modifications will void the warranty and may pose safety risks.

3. Setup and Installation

The THERMASGARD ATM2 sensor is designed for straightforward installation. Ensure you have the necessary tools and follow local electrical codes.

1. Mounting Location: Select a suitable outdoor location that accurately represents the ambient temperature, away from direct sunlight, heat sources, or strong air currents that could affect readings. Consider mounting on a north-facing wall if possible.
2. Mounting the Device:
   • Open the housing using the quick-release screws.
   • Secure the base of the sensor to the chosen surface using appropriate screws (not included). Ensure it is mounted firmly.
3. Wiring:
   • Route the necessary electrical cables through the cable gland at the bottom of the housing.
   • Connect the power supply and output signals to the designated terminals inside the sensor. Refer to the wiring diagram provided with the device for specific connections.
   • Ensure all connections are secure and properly insulated.
4. Sensor Configuration (if applicable): If your model allows for internal/external sensor selection or range switching, configure these settings according to your application requirements before closing the housing.
5. Close Housing: Securely close the housing using the quick-release screws, ensuring a tight seal to protect against environmental elements.

4. Operating Instructions

Once properly installed and powered, the THERMASGARD ATM2 sensor operates continuously to provide temperature readings.

• Power On: Apply power to the device. The sensor will begin taking measurements immediately.
• Data Output: The sensor provides a continuous output signal (e.g., 0-10V, 4-20mA depending on model and configuration) corresponding to the measured temperature. This signal can be read by a compatible control system, PLC, or display unit.
• Calibration: The ATM2 is a calibratable sensor. If recalibration is required, refer to the detailed calibration procedure in the full technical datasheet or consult a qualified technician. This typically involves adjusting internal potentiometers or software settings to match a known reference temperature.
• Measuring Ranges: The sensor supports eight switchable measuring ranges. Ensure the selected range matches your application's requirements for optimal accuracy.

5. Maintenance

Regular maintenance helps ensure the longevity and accuracy of your THERMASGARD ATM2 sensor.

• Cleaning: Periodically clean the exterior of the sensor housing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the temperature probe is free from debris.
• Inspection: Annually inspect the housing for any signs of damage, cracks, or loose quick-release screws. Check the cable gland for a secure seal.
• Recalibration: Depending on the application and required accuracy, periodic recalibration may be necessary. Consult your system's maintenance schedule or a qualified technician.
• Environmental Check: Ensure the area around the sensor remains clear of obstructions that could affect airflow or expose the sensor to unintended heat/cold sources.
