Proximity Series QV Quick-View Rotary Position Indicators/Switches are
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, using a #6-32 X 1/4˝ screw provided. Do not attempt to fabricate your own
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. For lever drive models, attach the appropriate driving lever onto the shaft. 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. replace OPen/CLOSeD indicator drum making sure incoming wires are tucked
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.
