Series QV Quick-View®Rotary Position Indicator/Switch
Specications - Installation and Operating Instructions
Bulletin F-87
Proximity Series QV Quick-View®Rotary Position Indicator/Switch is produced
with up to four individual mechanical or proximity switches. Instructions below include
installation, as well as adjustment procedures for direct drive and lever drive models.
INSTALLATION
1. Mounting kits, when provided include couplers, lever arms and screws for
mounting the position indicator to a valve or actuator. A position indicator is
mounted using direct drive hardware for quarter turn applications (rotational) and
lever drive hardware for converting linear motion to rotary. Tubular spacers are also
provided for some installations.
2. For direct drive models, attach appropriate drive yoke or solid block onto the two
pins,usinga#6-32X1/4˝screwprovided.Donotattempttofabricateyourown
yokes since this a special spring-tempered material. For direct drives, with the
actuator shaft rotated to its counterclockwise position, spread the driving yoke and
slip it down onto the square (or rectangular) shaft of the actuator. Attach bracket
with two hex cap screws. Before tightening screws, operate control slowly with
a wrench or power, and observe that drive shaft and drive yoke are concentric and
perpendicular throughout the complete stroke. Adjust position as required and
tighten all mounting screws. Check concentricity and perpendicularity.
3. Forleverdrivemodels,attachtheappropriatedrivingleverontotheshaft.Do
not tighten. Attach switch and bracket to actuator, making sure that the lever is
free to rotate over the entire range of the actuator stroke. Attach the driving pin
or bolt through the lever arm if slotted, or on the driving side of the lever. (It may
be necessary to loosen or remove the bracket mounting to accomplish this
connection on some actuators.) Operate the actuator very slowly and observe
movement of all pins and levers to be sure there are no interferences. Slide lever
up or down on switch shaft to the most desirable position. When all motions are
made and clearances are adequate, tighten clamp screw on lever that was left
loose above. Now tighten all the mounting screws. Re-check the travel of all levers
and pins for proper clearance throughout the complete stroke of the actuator.
4. Push cover down, then turn it counterclockwise and lift straight up to remove.
Remove inner cover window. Remove the indicator drum.
5. Switches are set at the factory in the counterclockwise position listed below:

ADJUSTMENT PROCEDURE
1. Using wrench or power, rotate the actuator shaft to extreme clockwise position
for direct drive applications. For linear applications, operate actuator to full closed
position. All switches should change to their appropriate functions.
2. The cam can be relocated and repositioned by loosening the set screw. To adjust
manual cams grasp cam on knurled segment of cam surface. Rotate cam
clockwise or counterclockwise to obtain correct actuation point. Feeling or sound
of clicks indicates incremental adjustments. Applying pressure on cam in direction
of actuation segment of cam surface, and rotating, eliminates incremental
adjustments. Stop rotating and release pressure on the cam when it is at proper
actuation point; this allows engagement of cam to spline. Check circuit to verify
contact at proper point. Rotate the shaft counterclockwise. Repeat all steps above
as necessary. Lock cam on spine with set screw provided for additional security.
3. Operate actuator to extreme opposite position to verify correct operation of
switch(es). Readjust as required.
4. ReplaceOPEN/CLOSEDindicatordrummakingsureincomingwiresaretucked
in so as not to rub against the drum. Replace cover window making sure it lines
up correctly with indicator to display the proper indication of valve position. Replace
snap-on cover.
WIRING
Complete all electrical wiring in accordance with Local and National Codes. Tighten all
screws. (Sealed leads are provided from the factory on request).
MAINTENANCE
The Series QV Rotary Position Indicator/Switch is not eld serviceable and should
be returned if repair is needed (eld repair should not be attempted and may void
warranty). Be sure to include a brief description of the problem plus any relevant
application notes. Contact customer service to receive a return goods authorization
number before shipping
