c. Operational Description. The Model PP814T Torque Type Power Positioner is a pneumatic driven, double acting piston type power cylinder in which the linkage lever is positioned to a specific setting for each input signal. The power positioner is mounted on a steel floor stand. The unit is covered and protected by a splash proof metal dust cover. The power positioner is used to position devices such as inlet vanes, control valves, and dampers.
The upward movement of the piston rod moves the cam downward. This causes the follower arm, riding on the cam, to lift the spring nut, increasing pressure on the calibration spring. This increased pressure on the calibration spring returns the diaphragm to its neutral position, closing the pilot valve air ports. Without additional air pressure, piston movement is stopped. As signal air decreases the calibration spring pressure moves the diaphragm up.

c. Storaee Preventive Maintenance. If storing power positioner longer than six months, observe the following preventive maintenance guidelines. 1. Cycle cylinder and piston either manually or by air every six months. 2. Perform General Cleaning and Lubrication (paragraph 6.3), and Cylinder and Piston, Cleaning and Lubrication (paragraph 6.9), before installing power positioner.
SECTION 2-1. 2-2. II. INSTALLATION OVERVIEW. The power positioner is designed to be installed upright. The floor stand is bolted to a prepared horizontal foundation. A minimum of 45 psig to a maximum of 120 psig supply air pressure is needed at mounting location. The power positioner must be controlled by either a” electrical signal, when “sing a” I/P signal converter, or by a” air signal. All wiring must conform to local and national codes. which flow changes per valve position is increawl.

Foundation must be able to withstand at least 1670 ft-lbs torque plus 900 lbs weight. Refer to Figure 2-2 for footprint dimensions of power positioner. Use this footprint as a guide to design foundation to match baseof power positioner. Mounting holesin baseare drilled for 3/4 inch foundation bolts.

2-6. LINKAGE INSTALLATION. I” a “mnal installation, most customers install the linkage with both the drive Amy and damper driven arm positioned so that both anns establish a” approximate right angle (90”) to the drive line at mid range of travel as illustrated in Figure 2-5. For more detailed information on linkage arrangement and options refer to Appendix A LINKAGE INSTALLATION FOR EITHER A CHARACTERIZED FLOW CONTROL DEVICE, OR A LINEAR FLOW CONTROL DEVICE. I DRIVEN - LINKAGE DRIVE Figure 2-5.
SECTION 3-1. III. REVERSE OPERATIONAL DESCRIPTION. In reverse acting positioners, the piston and piston rod operate. the same as when set up for direct acting (Figure l-2). The cam is reversed front to back and the cylinder air hoses are exchanged. These alterations cause supply air to be directed to the top of piston when signal air pressure is increased and to the bottom of piston when signal air pressure is decreased. In this case, piston movement is inversely OPERATION related to the signal.
a. Reverse Assembly. Com~ematine c. Calibrate Stroke. 1. Disconnect linkage lever (1, Figure 3-l) at clevis (2) from device being controlled. 1. Remove power positioner from service. 2. Open supply air valve. This will cause piston rod (15) to move to top of its stroke. Set signal air to minimum. 2. Close the supply air valve 3. Set signal air to 0. 4. Remove pivot screw (4) and stroke adjustment lock screw (3) securing cam (5) to cam mounting bracket (6) and remove cam. 5.
SECTION 4 -1. IV. CALIBRATION CHECK POWER POSITIONER CALIBRATION. Use the following procedure to check calibration of power positioner. Figure 4-1, Calibration Flowchart is provided as a quick reference guide. IS PERCENTAGE OF TRAVEL OF DEVICE EQUAL TO CORRESPONDING PERCENTAGE OF NOTE If cam was shaped (characterized), values of percent output desired must be recorded upon instalIation in Table 4-1, Schedule D. This is necessary to check calibration.

SECTION 10-l. X. RETURNING EQUIPMENT If factory repair of defective equipment is required, proceed as follows: a. Secure a return authorization from a Rosemount Analytical Sales Office or Representative before returning the equipment. Equipment must be returned with complete identification in accordance with Rosemount instructions or it will not be accepted. In no event will Rosemount equipment without proper identification. be responsible for authorization and b.
APPENDIX CHARACTERIZED A. LINKAGE INSTALLATION FLOW CONTROL DEVICE, CONTROL DEVICE. FOR EITHER OR A LINEAR A FLOW Linkage installed for a characterized flow control device will result in rapid flow changes near the closed position. A linear flow control device will provide linear changes in flow in relation to changes in control signal. Characterized flow control device results from linear linkage and linear power positioner.
NOTE NOTE Linkage installation described in this section of the manual is for direct acting power positioners. The following known values are wed calculate the vertical distance travelled the drive lever; “Y”. a. Characterized Linkage System. R, = 1. Make Sue. a linear cam is installed to get linear outputs from power positioner. 2.

(e) Clear calculator. (f) Enter value for PI and press cosine key (COS). (g) Multiply answer from step (f) length of driven lever (RJ. (h) Write answer from step (g) down and label (8). Clear calculator. (i) Add anwer marked (c).
(t) Clear calculator. (u) Enter value for PI and press sine key mv. (v) Multiply answer from step (u) by length of driven lever (RJ. (w) Write down answer from step (v) and label (v). Clear calculator. (x) Subtract value marked (v) from value marked (r). (y) Add answer marked (n). (z) Press square root function key (Jx). from step (x) to value CLEVIS -1 (aa) The value in step (z) is equal to length of connecting linkage “0 “.
(e) Install power positioner’s drive lever so its angle. from vatical center line (0,) is equal to device’s driven lever angle @,). (f) Measure distance (0) between drive and driven levers connection holes. Allowing for clevis length, cut pipe to fit this meamrement. Attach clevises. (g) Install linkage pipe between drive and driven levers. Check for freedom of operating power movement by positioner’s handwheel.

APPENDIX B. ELECTRIC POSITION 8 INCH x 14 INCH POWER SECTION B-l. AMPLIFIER a. FOR I. DESCRIPTION The Rosemount Electric Position Transmitter Field Retrofit Kit is designed for installation on the Rosemount 8 x 14 Torque Type Power Positioner. It transmits the position of the piston rod through a mechanical linkage to a potentiometer.
NOTE e. Move the power positioner to the opposite end of its stroke and hme the span adjustment (as labeled on amplifier cover) for a reading of 20 mA. f. Replace two plug buttons (1, Figure B-2) in EPT case. g. Install power positioner cover and secure with screws removed at disassembly An ammeter may be connected in series for amplifier calibration to verify position indicating meter is giving accurate readings. d. With the amplifier power supply on, move power positioner shaft to zero position.
