When installing and operating rotary actuators types GNP.. in low-noise environments,

check the acoustic response of the actuators operated together with the measuring and

control equipment.

The combination with differential pressure sensors, sensors, and controllers may result

in unwanted operational noise based on the operating settings, regardless of the given

manufacturer.

· Low-noise HVAC plants in general

· Supply and extract air plants

· Fume hood control plants

· Room pressure control plants

e.g. Laboratories / fume hoods, hospital rooms or similar plants

We recommend using rotary actuator HLV40.1 if the applications listed above are

motorized or in the event of any general concerns regarding operational noise of GNP

actuators (Contact your local Siemens representative).

The actuators preset at the factory to:

· 0… 10 V

· Clockwise rotary movement

· Counter-clockwise fail-safe movement
