4 614OpenAir TMAirdamperactuatorsRotary version with spring return, AC 24 V / AC 230 VGMA...1Electronic motor driven actuators for two-position, three-position, andmodulating control, nominal torque 7 Nm, with spring return, self-centering shaftadapter, mechanically adjustable span between 0...90°, prewired with 0.9 m longconnection cables.Type-specific variations with adjustable offset and span for the positioningsignal, position indicator, feedback potentiometer, self-adaptation of the rotaryangle range, and adjustable auxiliary switches for supplementary functions.RemarksThis data sheet provides a brief overview of these actuators. Please refer to thetechnical basics in CM2Z4614en for a detailed description as well as information onsafety, engineering notes, mounting and commissioning.Use• For damper areas up to 1.5 m 2 , friction-dependent.• In ventilation sections where the actuator must move to the zero position (emergencyposition) during power failure.• For dampers having two actuators on the same damper shaft (tandem-mountedactuators or Powerpack).CM2N4614en16.03.2001Siemens Building TechnologiesLandis & Staefa Division

For this reason,order the type that includes the required options.2/4Siemens Building Technologies Air damper actuators GMA...1, rotary version with spring return CM2N4614enLandis & Staefa Division 16.03.2001
