SECTION l-l. I. COMPONENT CHECKLIST OF TYPICAL SYSTEM (PACKAGE CONTENTS). A typical Rosemount 4 X 5 Power Positioner package should contain the items shown in Figure. l-l. 1-2. MODEL NUMBER MATRIX. Use model number matrix, Table 1-1, to verify your style number. The first pat of matrix defines the model. The last part defines various options and features of the power positioner. Copy your model number from data plate located on side of power positioner, into top of matrix Table 1-1.
air signal controls the power positioner. This air signal can be direct or inverse, and have a range of 3 to 15, 0 to 30, 3 to 27, or 0 to 60 psig. 5. The pressure regulator/filter “l”i”t”i”s a stable and filtered air supply to the I/P converter. 6. The supply air filter will remove finely dispersed water or oil droplets from supply air. Supply air must be free of oil and water to prevent pilot valve Xicking. I.
OPERATING , DIRECT \I I ACTING - INCREASING SIGNAL SCHEMATTIC SILENCER Figure 1-2.
(c) Square-Root Shaped Cam. The squareroot (Jx) shape will prcduce a relatively large output change. for small input chaoges during approximately the first 10% of signal range. When operating in the “pper portion of the signal range, a large input change will be required to produce a small output change. I” this type of installation, piston movement is inversely related to the signal -as signal pressure decreases, the piston lowers, as signal pressure raises, the piston raises. 4. Manual Operation.
b. Power Positioner Preparation for Storage. WARNING Keep Tectyl 506 away from beat, sparks, and open flames. Use with adequate ventilation to cure and to prevent an explosive atmosphere from for&g. CAUTION Use only approved thinning methods when applying rust-preventive compounds. Do not apply heat to compound. Fire or explosion may result. Refer to manufacture of rustpreventive compound for specific application, thinning, clean-up and removal instructions.
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 an elect&J signal, when using ao I/P signal converter, or by an air signal. All wiring must conform to local and national codes. SPECIAL INSTALLATION position is reduced.

3. Become familiar with all of Section II, Installation, before actual installation is started. e. Mounting (c) If power positioner is not level, remove l/Z inch bolts that secure power positioner to foundation and install shims between the power positioner and foundation. Continue this process until power positioner is level when l/2 inch mounting bolts are tightened. This will prevent distortion of power positioner stand.

(e) Close dmnper to minimum flow position.
Cc) Check power positioner calibration and make sure linear cam is installed. Refer to paragraphs 4-2 and 4-3. Make any adjustments to power positioner prior to cutting cam. (4 Copy “System Flow Chart” (Table 2-l). Measure and record actual flow of system starting at 0% input signal to power positioner and increasing up to 100% in increments of 20%. Divide actual flow by flow at 100% input signal to determine percent flow. Enter percent flow in percent flow column in Table 2-l.

Using a file or similar tool, smooth carve until no ridges or imperfections are felt on edge of c.arve.
SECTION 3-1. III. REVERSE OPERATION OPERATIONAL DESCRIPTION. In reverse action positioners, piston and piston rod movement react opposite as direct acting positioners (Figure l-2). An inverse cam is installed and supply air hoses to the cylinder are reversed. ‘Ihe switched hoses cause supply air to pressurize below piston for increasing signal air pressures and above piston for decreasing signal air pressures. In this case, piston movement is inversely related to the signal.
