2. סעטאַפּ און ייַנמאָנטירונג

The M9310-HGA-2 actuator is designed for direct mounting, eliminating the need for external damper linkage in most applications. Ensure all local and national electrical codes are followed during installation.

2.1 דירעקט מאַונטינג

The actuator can be directly coupled to a damper shaft using its universal clamp. It supports:

• ארום דamper shafts from 3/8 in. (10 mm) up to 1-1/16 in. (27 mm).
• קוואַדראַט דamper shafts from 3/8 in. (10 mm) up to 3/4 in. (19 mm).

2.2 Remote Mounting and Accessories

For applications where direct coupling to the damper shaft is not feasible, an accessory crank arm and remote mounting kit are available. These kits provide flexibility for installation in various configurations.

2.3 Auxiliary Switch Installation

An optional line voltage auxiliary switch kit can be field-installed. This switch can be used to indicate an end-stop position of the damper or to perform additional switching functions within the selected rotation range.

3. אַפּערייטינג ינסטרוקטיאָנס

The M9310-HGA-2 actuator supports various control strategies, including on/off, floating, and proportional control, thanks to its Automatic Signal Input Detection feature. The actuator automatically recognizes the input signal type and adjusts its operation accordingly.

3.1 קאָנטראָל מאָדעס

• אָנ / אַוועק קאָנטראָל: The actuator drives the damper to either a fully open or fully closed position based on a simple binary signal.
• Floating Control: The actuator moves the damper incrementally in response to pulsed signals, allowing for intermediate positions.
• פּראָפּאָרטיאָנאַל קאָנטראָל: The actuator positions the damper proportionally to an analog input signal (e.g., 0-10VDC or 4-20mA), providing precise modulation.

3.2 Self-Calibration and Stall Detection

The actuator features a self-calibrating input signal function, which optimizes the stroke adjustment for precise damper positioning. Electronic stall detection is integrated to protect the actuator from damage in case of an obstruction or excessive load, ensuring reliable long-term operation.

4. וישאַלט

The Johnson Controls M9310-HGA-2 Damper Actuator is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance and longevity.
