4. Подешавање

Proper installation is critical for the accurate and safe operation of the GD300-NH3 detector. It is highly recommended that installation be performed by a certified professional.

4.1. Место монтаже

• Choose a location where ammonia gas is most likely to accumulate. Ammonia is lighter than air, so detectors should typically be mounted near the ceiling or at a higher level.
• Avoid mounting near ventilation outlets, doors, windows, or direct heat sources that could affect readings.
• Уверите се да је површина за монтажу стабилна и без вибрација.
• Allow sufficient space around the detector for maintenance and access.

4.2. Ожичење и прикључак за напајање

• The GD300-NH3 requires a 24V DC power supply. Ensure the power source meets the specified voltage and current requirements (100mA).
• Connect the 3-wire 4-20mA signal output to your control system (PLC, DCS) as per the system's wiring diagram.
• Use appropriate explosion-proof cable glands and conduits to maintain the integrity of the explosion-proof enclosure.
• Verify all connections are secure and correctly polarized before applying power.

4.3. Почетно укључивање

• After installation and wiring are complete, apply power to the detector.
• The device will undergo a self-test and warm-up period. During this time, the display may show varying readings or diagnostic codes.
• Allow the detector to stabilize for at least 5-10 minutes before assuming normal operation.

5. Оперативни

Once installed and powered, the GD300-NH3 operates continuously to monitor ammonia levels.

5.1. Очитавање дисплеја

• The digital display shows the current ammonia concentration in parts per million (ppm).
• Observe the display for real-time readings.

5.2. Alarm Indications

The detector features two levels of sound and light alarms:

• Level 1 Alarm: Triggered when ammonia concentration reaches the first preset alarm point. The red light will flash, and an audible alarm will sound.
• Level 2 Alarm: Triggered when ammonia concentration reaches the second, higher preset alarm point. The red light will flash more rapidly, and the audible alarm will be more urgent.
• Alarm points can be configured during setup or maintenance using the remote control.

5.3. Функција даљинског управљача

The included remote control allows for convenient adjustment of settings without needing to open the detector's cover. Functions typically include:

• Setting alarm points.
• Zero-point calibration.
• Address modification (for networked systems).

Refer to the remote control's specific instructions for detailed usage.

6. Одржавање

Regular maintenance ensures the longevity and accuracy of your GD300-NH3 detector.

6.1. Калибрација

The GD300-NH3 has a self-calibration function. Regular calibration (e.g., every 6-12 months, or as required by local regulations) is crucial to maintain accuracy. Use certified standard gas for calibration. Follow the on-screen prompts and remote control instructions for the calibration process.

6.2. Чишћење

• Periodically clean the exterior of the detector with a soft, damp тканина.
• Немојте користити абразивна средства за чишћење или раствараче.
• Ensure the sensor opening is free from dust, debris, or obstructions.

6.3. Сенсор Реплацемент

The electrochemical sensor has a limited lifespan. If the detector consistently provides inaccurate readings after calibration, or if a sensor fault is indicated, the sensor may need replacement. Contact GasDog support or a qualified technician for sensor replacement.
