Adjusting the hesitation point on your Siemens 331-2930 Powers Controls Pneumatic Damper Actuator is straightforward. Follow these steps for optimal performance:

1. Initial Air Pressure Adjustment: Apply air pressure to the actuator until the actuator shaft reaches your required position. This sets the starting point for your damper's movement.

2. Cycle Adjustment: Locate the cycle adjustment rods. Turn the locknuts on these rods until they make contact with the lower housing of the actuator. Once contact is made, secure the locknuts together. It's crucial to tighten these nuts evenly to ensure the damper actuator operates smoothly. By carefully following these steps, you'll be able to fine-tune the hesitation point, ensuring your Siemens 331-2930 Powers Controls Actuator operates exactly as needed.
