Orderable Service Parts.OperationGCA12x and GCA22x: 2-Position ControlWhen power is applied, the actuator coupling moves toward the open position 90 .GCA13x: Floating ControlA floating control signal controls the damper actuator. The actuator's angle ofrotation is proportional to the length of time the signal is applied. A 24 Vac/dc controlsignal to Y1 causes the actuator coupling to rotate clockwise. A 24 Vac/dc controlsignal to Y2 causes the actuator coupling to rotate counterclockwise.With no control voltage, the damper actuator holds its position.GCA16x and GCA15x: Modulating ControlA continuous 0 to 10 Vdc or 2 to 10 Vdc signal from a controller to wire Y operatesthe damper actuator. The angle of rotation is proportional (or inverse proportional) tothe control signal. A 0 to 10 Vdc, or 2 to 10 Vdc position feedback output signal isavailable between wires U and G0 (system neutral) to monitor the position of thedamper actuator.In the event of a power failure or when the operating voltage is shut off, all actuatormodels will return to the 0 position.In the event of a blockage in a damper, actuators are overload protected over thefull range to prevent damage to the actuators.Life expectancyPage 8An improperly tuned loop will cause excessive repositioning that will shorten the lifeof the actuator.Siemens Industry, Inc.

OpenAir GCA Series Spring Return 160 lb-in Electronic Damper ActuatorSizingTechnical InstructionsDocument No. 155-173P25April 9, 2012The type of actuator required depends on several factors.1. Obtain damper torque ratings (ft-lb/ft2 or Nm/m2) from the dampermanufacturer.2. Determine the area of the damper.3. Calculate the total torque required to move the damper:Total Torque Torque Rating Damper AreaSF 11Safety Factor: When calculating the total torque required, a safety factorshould be included for unaccountable variables such as slight misalignments,aging of the damper, etc. A suggested safety factor is 0.80.4.

Actuator mustbe in the vertical position. The shaft adapter and the position indicator can be mounted on either side of the actuator. The actuatormounting orientation and shaft length determine how they will be mounted on the actuator. The minimum damper drive shaft length is 3/4-inch (20 mm). See Specifications for the minimum and maximum damper shaft dimensions. The actuator is shipped from the factory with a 5 preload enabling tight close off of the damper inpower-fail-close applications. A mounting bracket is included with the actuator. The shaft adapter and mounting parts are shipped in a separate container with the actuator. See the detailed mounting instructions included with each actuator.Page 12Siemens Industry, Inc.

Check the Auxiliary Switch A:a.Set the DMM dial to ohms (resistance) or continuity check.b.Connect wires S1 and S3 to the DMM. The DMM should indicate open circuit or no resistance.c.Apply the input signal as in Step 1d, to wire 8 (gray).The DMM should indicate contact closure as the actuator shaft coupling reaches the setting ofswitch A.d.Connect wires S1 and S2 to the DMM. The DMM should indicate open circuit or no resistance.e.Apply the input signal as in Step 1f, to wire 8 (gray).The DMM should indicate contact closure as the actuator shaft coupling reaches the setting ofswitch A.5. Check the Auxiliary Switch B:a. Set the DMM dial to ohms (resistance) or continuity check.b. Connect wires S4 and S6 to the DMM.
