to determine
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
−
If the stroke of the No. 6 damper
actuator has been adjusted, see

point pressure.

Installation
Setting the span
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
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:
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.
The line to the left of the number is the
setting.

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

.
Adjusting the start point
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 (
clockwise to increase the start point pressure
and counterclockwise to decrease the pressure.

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
5. Repeat steps 1 through 4 until you get the
desired
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.

Calculating the span setting
1. Identify the stem/stroke travel from
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
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:

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
