3. Produk Lebihview

The Johnson Controls M9116-AGA-2 is an electric non-spring-return actuator designed for precise control in various industrial applications. It offers on/off, floating, proportional, or resistive control capabilities and provides 16 Nm (140 in-lb) of torque.

Ciri-ciri Utama:

• Simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages.
• Four control inputs meet the needs of most applications.
• Output position feedback provides simple closed-loop control with accurate position sensing.
• Electronic stall detection ensures higher reliability by deactivating the actuator motor when a stall condition is detected.
• NPT threaded housing provides easy connection for electrical fittings.

Komponen:

The actuator features a robust housing, a direct-mount coupling mechanism, and clearly labeled electrical terminals. The image below illustrates a typical M9116 series actuator.

4. Pemasangan (Persediaan)

4.1 Pemasangan

The M9116-AGA-2 actuator can be direct or remote mounted. It is designed for easy installation on a damper with a round shaft up to 3/4 inch (20 mm) in diameter or a square shaft up to 5/8 inch (16 mm). For valve applications, use one of the M9000-5xx Valve Linkage Kits.

• Ensure the mounting surface is stable and capable of supporting the actuator's weight.
• Securely attach the actuator to the shaft using the provided hardware.
• Verify that the actuator has a full range of motion without obstruction.

4.2 Pendawaian

Refer to the wiring diagram on the actuator label (Figure 1) and local electrical codes for proper connections. The actuator operates on AC/DC 24 V power.

• COM: Common terminal.
• +24: 24V AC/DC power supply.
• Y2, Y1: Control input terminals for on/off or floating control.
• U: Feedback signal output (DC 0(2)-10V).
• mA, VDC: Additional input/output terminals for specific control types (e.g., 0(4)-20mA, 0(2)-10V).

The NPT threaded housing facilitates easy connection for electrical conduits.

5. Operasi

5.1 Control Types

The M9116-AGA-2 actuator supports various control signals:

• Kawalan Hidup/Mati: Actuator moves to fully open or fully closed position based on a simple switch signal.
• Floating Control: Actuator position is adjusted by pulsed signals, allowing for intermediate positions.
• Kawalan Berkadar: Actuator position is proportional to an analog input signal (e.g., 0-10V DC or 4-20mA).
• Resistive Control: Actuator position is controlled by a resistive input.

5.2 Angle of Rotation Adjustment

The angle of rotation can be mechanically adjusted from 0 to 90 degrees in 5-degree increments. This allows for precise calibration to match specific application requirements.

5.3 Fungsi Bantu

Integral auxiliary switches are available to indicate end-stop positions or to perform switching functions at any angle within the selected rotation range. Position feedback is provided through switches, a potentiometer, or a DC 0(2) to 10 V signal, enabling closed-loop control systems.

6. Penyelenggaraan

The M9116-AGA-2 actuator is designed for reliable, long-term operation with minimal maintenance. Periodic checks are recommended:

• Inspect wiring connections for tightness and signs of wear.
• Ensure the actuator housing is free from dust and debris.
• Verify that the shaft connection remains secure and free of play.
• No lubrication is required for internal components.

7. Penyelesaian masalah

If the actuator is not functioning as expected, consider the following:

• Tiada Pergerakan: Check power supply connections and ensure the correct voltage is applied. Verify control signal input.
• Kedudukan yang salah: Re-check control signal calibration and mechanical angle adjustments.
• Bunyi Luar Biasa: Inspect for mechanical obstructions or loose mounting.

Electronic Stall Detection:

The actuator features electronic stall detection, which deactivates the motor if an obstruction prevents movement. If a stall occurs, remove the obstruction and cycle power to reset the actuator.
