Actuator Installation D1300 D1350

Installation of Airtech Products Durastroke pneumatic actuator is a simple three-step process; Mounting of the actuator & attachment to load, connection of air line and connection of the control signal. Before starting installation, inspect the actuator and contents of the shipping carton to ensure all required parts are present. Check the following:  Ensure all parts are firmly secured to the mounting plate and the mounting plate is firmly secured to the actuator body.  Clevis is present at the end of travel stem?  The following hardware kit was included: 1. Five (5) 3/8-16 x 1 ½” long bolts 2. Four (4) 3/8” lock washers 3. One (1) 3/8-16 locking nutA) Mounting The Actuator:1. The actuator can be mounted in either a vertical or horizontal position. 2. The actuator is supplied with four (4) 3/8”-16 bolt-holes in the bottom plate for attachment to a mounting plate or bracket. 3. A hole at least 13/16” (but not larger than 1” diameter) must be provided in the center of the actuator mounting bolthole pattern for penetration of the actuator travel stem and clevis. 4. Attach the actuator to the mounting bracket with the four supplied 3/8”-16 x 1½ ” bolts and lock washers. In a rotating pattern, tighten each to 16 Ft-Lbs torque. 5. DO NOT ATTACH THE ACTUATOR TO THE TORQUE TUBE LEVER ARM YET.B) Air Line Connections:1. Blow out all piping before connections are made to prevent dirt, chips, etc from entering the positioner. Ensure all air entering the positioner and actuator is clean, dry and oil free. Failure to do so increases the possibility of operational problems and/or deviation from specified performance. 2. Locate the 1/4” NPT ports labeled, “Supply” and “instrument” on the Siemens 73N12F positioner. 3. Install a 1/4” threaded adapter in the air inlet ports and use Teflon tape or non-hardening sealant on threads of male connectors. 4. As appropriate, connect 1/4” or 3/8” air-line to the Supply and Instrument ports on the positioner. The supply line is “Plant Air” reduced to no more than 50 psi. The Instrument air is plumbed directly off the output of the I/P transducer.1550 S. 81st W. Avenue  Tulsa, OK 74127 Office: 918-241-0264  www.airtechproducts.comD) Connecting The Linkage:1. In most cases**, the torque tube lever arm will be preset at the factory to drive the louver either “Fail Open” or “Fail Closed” upon loss of air and / or actuator retraction. As a result, connection of the linkage will be a simple matter of manually situating the louver blades and actuator stem to the correct position and then attaching the control link to the clevis (at the base of the actuator stem) and finally to the torque tube lever arm. To determine how the actuator and louver blades should be positioned, please note the following instructions: “Fail Open” Louvers  Stroke actuator to fully extended and manually set louver to fully closed position before connecting louver lever arm & link to actuator clevis. b. “Fail Closed” Louvers  Ensure actuator is completely retracted and manually set louvers to fully closed position before connecting louver lever arm & link to actuator clevis. 2. When all sections are installed and connected, stroke the actuator several times
