Determine the direction of the damper shaft rotation (clockwise or counterclockwise) on an increase in pressure to the actuator. 2. Determine the angle of rotation required for the damper to move from closed to full open. NOTE: Since the actuator stroke is 2-3/8 inches (6 cm) and the angle of rotation is known, the crank radius can be determined from the graph in (TB 181 Maximum Thrust Ratings of Pneumatic Damper Actuators (155-219P25155-219P25) or use Table 2.

Attach the clevis and other end of the linkage to the actuator shaft (Figure 3). 5. The normal position of the damper (open or closed) and its direction of rotation (CW or CCW) will determine the location of the actuator and linkage assembly (Table 1 and Figure 3). 6. Attach an airline or Baumanometer (squeeze bulb) to the actuator and increase pressure until the actuator shaft moves one half of its stroke, 1-3/16 inches (3 cm). Select the correct location for the actuator assembly as determined in Step 5. 7. Slip the crank over the damper shaft and position the assembly so that the actuator shaft and link are straight and perpendicular to the crank. 8. Mark and attach the actuator bracket to the duct at this location. If this installation procedure is followed, there will be no problem with linkage scissoring or locking up. The installation is now complete. Table 2. Crank Radius Connection. Dimensions Application Crank X 7-7/8 in. (200 mm) 7-7/8 in. (200 mm) NOTE: Y 1-3/16 in. (30 mm) 2-1/16 in. (52 mm) 2-3/8 in.

Document No. 129-125 RL 147 Positioning Relay Calibration Description This sheet provides the instructions to calibrate the RL 147 Positioning Relay after it has been mounted on an actuator. 147-2000 Required Tools Medium flat-blade screwdriver Tubing, pressure gauge, and squeeze bulb (Part of Calibration kit 832-177) Two 5/8-inch open end wrenches Two 7/16-inch open end wrenches for valve stems of 1/4-inch diameter Expected Installation Time 10 Minutes Prerequisites For field installed relays, mount the positioning relay on the actuator according to the instructions that are packaged with the mounting kit. Check that you have the correct feedback spring(s) attached. If the positioning relay is mounted on a valve, see Tables 4 and 6. If the stroke of the No. 6 damper actuator has been adjusted, see Table 1. Identify the desired operating span and the start point pressure. NOTE: Installation In some cases, the actuator stem travel or stroke is not identical to the nominal value of the relay feedback spring. See Calculating The Span Setting to determine the span setting on the feedback arm. Setting the span (See Figure 1) The positioning relay operating span can be set for spans of 3 to 12 psig (21 to 83 kpa). For spans of 3 through 10 psig (21 to 69 kpa) 1. Check that the feedback spring is attached to the spring guide in the hole across from the span adjustment screw. This is identified as the standard location in Figure 1. 2. With a screwdriver, loosen the span adjustment screw. Move the spring guide on the feedback arm until the span adjustment tab is at the desired span setting reference number. NOTE: The line to the left of the number is the setting. 3. Tighten the span adjustment screw. 4. The feedback spring must be parallel to the actuator shaft or valve stem. Use the open end wrenches to loosen the hex nuts holding the spring arm in position on the shaft or stem. Align the feedback spring and tighten the hex nuts. 5. The feedback spring should have no slack or no stretch in it. Adjust the wing nuts and adjustment nut, if necessary. Page 1 of 5

Document No. 129-125 Installation, Continued Figure 1. Span Adjustment. Shown at Span Setting 8. For spans of 11 or 12 psig (76 or 83 kpa) 1. Move the span adjustment tab to the 10 setting on the feedback arm. Follow steps 2 and 3 for Setting the span. 2. Move the feedback spring one hole away from the standard location for a span of 11 psig (76 kpa) and two holes away from the standard spring location for a 12 psig (83 kpa) span. See Figure 1. 3. Follow steps 4 and 5 for Setting the span. Adjusting the start point (see Figure 2) The positioning relay can be adjusted to start actuator movement at pressures between 3 and 10 psig (21 and 69 kpa). 1. Remove the relay cover. 2. Attach tubing with a pressure gauge and squeeze bulb to the "T" port. Supply air should be attached to the "S" port. The "M" port should be attached to the connector on the actuator. 3. Using the squeeze bulb, apply pressure to the relay. Watch the valve stem or actuator shaft to see when it begins to move. Check the pressure gauge; this is the start point pressure. 4. If this is not the desired start point pressure, turn the start point adjustment nut (Figure 2) clockwise to increase the start point pressure and counterclockwise to decrease the pressure. 5. Repeat steps 3 and 4 until the stem or shaft begins to move at the desired pressure. Page 2 of 5 Figure 2. Start Point Adjustment Adjusting the span 1. Using the squeeze bulb, apply pressure to the relay. Note the pressure at which the stem or shaft begin to move. 2. Continue to apply pressure until the stem or shaft completes its full stroke. Note the pressure. 3. The difference between the two pressures is the span. 4. If the span is not the desired span, move the spring guide to a higher reference number to increase the span or lower number to decrease the span. See Figure 1 and Setting the Span. 5. Repeat steps 1 through 4 until you get the desired span. 6. If you have moved the spring guide, adjust the spring arm so that the spring is parallel to the stem or shaft. 7. Check the feedback spring. There should be no slack nor stretch in it. Adjust the wing nuts and adjustment nut, if necessary. 8. Fasten the relay cover. Fill in the information on the calibration label. 9. Attach the air line from the controller to the "T" port. Siemens Building Technologies, Inc.

Calculating the span setting Adjusting Screw 4-1/2 (114) long 1-3/4 (44) long 1. Identify the stem/stroke travel from Tables 1, 2, 3, 5, or 6. 2. If the stem travel matches a nominal spring travel listed in Table 4 there is no need to calculate a new span setting. 3. If the stem travel does not match a nominal spring travel listed in Table 4, chose the spring(s) whose maximum allowable travel is equal to or greater than the actual stem travel. 4. Calculate the span setting with the following formula: Formula for Span Setting Span setting = Desired span Nominal spring travel Actuator stroke Example: Determine the span setting for a valve having a desired span of 5 psig and 5/16-inch stroke. Select a spring with a maximum allowable range equal to or larger that the stroke. Use the 1/4-inch spring with a 3/8-inch maximum allowable travel range. See Table 4. Span setting = 5 x 0.25 0.312 = 4 Set the span adjustment tab to line 4 on the feedback arm to provide a 5 psig span for this valve. Table 2. for VF 599 Valve Bodies.
