The
Proximity
Controls
Indicator/Transmitter is a line of position indicators
with a selection of various output options. Three model
styles make up the Mark Series to cover almost any
application. A magnetic drive that completely seals the
switch compartment from the atmosphere for maximum
leak protection is utilized in the Mark 1. The Mark 3 uses
the same magnetic drive of the Mark 1, but it can be used
for multi-turn applications with 1 to 25 revolutions, such
as gate valves. A through shaft drive is incorporated in
the Mark 4 making the unit a lower cost alternative to the
Mark 1 for applications that are not as demanding.
Standard models in the Mark Series have visual position
submersible. A large variety of outputs are available to
outputs of 13 varieties including inductive sensors,
high temperature switches, gold contact switches,
hermetically sealed switches, and high current switches.
Aside from switch outputs, the Mark Series offers
potentiometer outputs, 4-20 mA transmitters, and HART
communication.
The units are purchased for either direct drive
applications, such as rotary valves, or lever drive
applications, such as linear valves. For the Mark 1, 3,
and 4 this instruction manual starts with installation of
the unit to the device being monitored, and the set up
of switch models. Separate instructions follow covering
the potentiometer and transmitter set up if your unit has
those options.

Proximity Controls has over 2000 kits assembly which saves labor and reduces cost. The available and can custom make kits for any application. - Page 7 A. Using a wrench or power, rotate the actuator shaft to extreme clockwise position. All switches should change to their opposite function. B. The cam can be relocated and repositioned by grasp cam on knurled segment of cam surface. Simply rotate the cam on spline attached to the pressure on cam when it is at proper actuation point.
- Page 8 A. Operate actuator to full closed position. Set screws hold cams in place on the shaft. For manual cams, grasp cam on knurled segment of cam surface and simply rotate cam to get correct actuation point. Clicks on cam in direction of protruding actuation segment of cam surface, and rotating, eliminates incremental on cam when at proper actuation point.
