3. Ürün Bittiview

The Johnson Controls A19ADB-2 is a direct immersion temperature controller designed for applications requiring precise temperature sensing and control. It features a robust housing and an immersion bulb for direct contact with the medium being controlled. The unit is capable of operating within a temperature range of 100°F to 240°F.

Şekil 1: Johnson Controls A19ADB-2 Direct Immersion Temperature Controller. This image shows the main unit with its gray protective casing, a visible adjustment dial on the top, and the copper immersion bulb extending from the right side, designed for direct contact with the controlled medium.

Temel Özellikler:

• Direct immersion sensing for accurate temperature measurement.
• Adjustable setpoint within 100°F to 240°F range.
• Durable construction suitable for industrial environments.
• Open-high (m/r open-hi) contact configuration.

4. Kurulum ve Kurulum

Installation of the A19ADB-2 controller requires careful attention to detail and adherence to safety protocols. It is recommended that installation be performed by a certified technician.

4.1 Kontrolörün Montajı

1. Select a suitable location for mounting the controller, ensuring it is easily accessible for adjustments and maintenance, and protected from excessive vibration or physical damage.
2. Ensure the immersion bulb can be fully submerged in the medium whose temperature is to be controlled.
3. Securely fasten the controller housing using appropriate mounting hardware.

4.2 Elektrik Kablolama

DİKKAT: Disconnect all power before making electrical connections.

• Refer to the wiring diagram provided with the unit (not included in this general manual) for specific connection points.
• Güç kaynağı kablolarını belirtilen terminallere bağlayın.
• Connect the load wires (e.g., to a heater or cooling element) to the appropriate control terminals.
• Gevşek temasları ve olası tehlikeleri önlemek için tüm bağlantıların sıkı ve güvenli olduğundan emin olun.

5. Kullanım Talimatları

Once installed and wired, the A19ADB-2 controller is ready for operation.

5.1 Sıcaklık Ayar Noktasının Belirlenmesi

1. Locate the adjustment knob on the top of the controller housing (refer to Figure 1).
2. Rotate the knob to align the desired temperature with the indicator mark. The temperature range is 100°F to 240°F.
3. The controller will now maintain the temperature of the immersed medium at or around the setpoint.

5.2 Understanding Control Action

The A19ADB-2 features an "open-high" (m/r open-hi) contact configuration. This typically means the control contacts open when the sensed temperature rises above the setpoint, and close when the temperature falls below the setpoint. This action is suitable for applications where the controlled device (e.g., a heater) needs to be turned off when the temperature is too high.

6. Bakım

The Johnson Controls A19ADB-2 is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity and accuracy.

• Temizlik: Keep the exterior of the controller clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Bağlantılar: Periodically inspect electrical connections for tightness and signs of corrosion.
• Immersion Bulb: Ensure the immersion bulb is clean and free from buildup that could affect temperature sensing accuracy.
• Kalibrasyon: While the unit is factory calibrated, if precise accuracy is critical and deviations are suspected, professional recalibration may be required.
