4. Installazione (configurazione)

4.1 Montaggio

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 Cablaggio

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.

• COMUNICAZIONE: Terminale comune.
• +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. Funzionamento

5.1 Control Types

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

• Controllo On/Off: Actuator moves to fully open or fully closed position based on a simple switch signal.
• Controllo flottante: Actuator position is adjusted by pulsed signals, allowing for intermediate positions.
• Controllo proporzionale: Actuator position is proportional to an analog input signal (e.g., 0-10V DC or 4-20mA).
• Controllo resistivo: Actuator position is controlled by a resistive input.

5.2 Regolazione dell'angolo di rotazione

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 Funzioni ausiliarie

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. Manutenzione

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. Risoluzione Dei Problemi

Se l'attuatore non funziona come previsto, considerare quanto segue:

• Nessun movimento: Controllare i collegamenti dell'alimentazione e assicurarsi che la tensione sia correttatage is applied. Verify control signal input.
• Posizionamento errato: Re-check control signal calibration and mechanical angle adjustments.
• Rumore insolito: Inspect for mechanical obstructions or loose mounting.

Rilevamento elettronico dello stallo:

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.
