Dwyer QV - Manual

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 mount-
ed using direct drive hardware for quarter turn applications (rotational) and lever
drive hardware for converting linear motion to rotary. Tubular spacers are also pro-
vided 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 nec-
essary 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 clear-
ances 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 prop-
er 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:
2 Switch unit #1 Open #2 Closed
4 Switch unit #1, 3 Open #2, 4 Closed
90° rotational travel will reverse all of the above positions.
