Typical Specifications
Spring return damper actuators shall be the type that requires no
connecting linkages. The spring return actuators shall have a self-
centering damper shaft coupling that assures concentric alignment of
the actuator’s output coupling with the damper shaft and be capable of
direct mounting to a shaft up to a 1-inch diameter. Actuators shall use a
brushless DC motor and provide stall protection throughout the full
range of rotation. All spring return actuators shall be capable of both
clockwise and counterclockwise spring return fail-safe operation using a
continuously engaged mechanical return spring that returns the actuator
to a fail-safe position in <20 seconds in response to a loss of power. All
actuators shall provide a means of manually positioning the output
coupling in the absence of power. Dual independently adjustable
auxiliary switches must be integral to the actuator. All actuators must be
precabled and provide an easily readable high contrast yellow on black
position indicator. All actuators shall be UL60730 and CSA22.2 listed
and manufactured under ISO 9002 and ISO 14000 procedures.
Actuators shall be designed for a minimum of 60,000 full stroke cycles
at the actuators rated torque and temperatures. Actuators shall be as
manufactured by Siemens Industry, Inc.
