The Proximity Mark Series 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 patented 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 indicators and
are weatherproof, flameproof, and submersible. A large variety of
outputs are available to fit specific applications. There is a choice of 1
to 6 switch outputs of 13 varieties including inductive sensors, high
temperature switches, gold contact switches, hermetically sealed
switches, and high current switches. Besides the switch outputs the
Series offers potentiometer outputs, 4 to 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.

JUNCTION PACKAGE
MOU
Complete factory assembled packages combine visual indication, solenoids, switches and
transmitter in a single convenient UL, CSA, SAA certified or ATEX compliant assembly which
saves labor and reduces cost. The simple package is shipped ready for installation, complete
with optional custom designed mounting kit for your specific application. Many options are
available such as painted aluminum, epoxy coated aluminum or stainless steel housings
including a standard 3/4” NPT conduit entrance and choice of 1 or 2 additional 1/2” NPT
conduit entrances. The optional conduit entrances are drilled and tapped in the base of the
position indicator housing and solenoid valves are screwed into the entrances. 22 to 16 AWG
wire leads from solenoids, switches and optional transmitter are terminated in prelabeled,
easy-access terminal strips protected inside the housing. Note: UL, CSA and SAA approval
and ATEX compliance requires complete package assembly by Proximity. Consult the factory
for recommended UL, CSA, SAA approved or ATEX compliant solenoid valve options. Please
consult page 3 and 4 for ATEX Safety Code.

Mounting kits are available for direct installation of the Proximity Mark Series onto most valve
and actuator brands. Proximity Controls has over 2000 kits available and can custom make kits
for any application. Each kit is specially designed for a particular actuator or valve, making field
mounting simple with standard tools. Mounting kits can be used with any model in the Mark
Series, since external features are identical. Rotary valve kits utilize direct drive couplings, while
linear valve kits use a lever drive.
Kits include a drive yoke or slotted lever arm, bracket, and fasteners made in either zinc plated
steel or stainless steel. The high strength, spring tempered, stainless steel drive yoke/coupling
is tailored to fit securely to a specific valve or actuator stem ensuring that there is no slippage
or binding. No special alignment fixtures are required due to switch-offset design and yoke to
stem engagement that makes installation a snap.
If you have purchased this unit without a mounting kit, please contact us to get the proper kit
for your application.

INSTALLATION PROCEDURE
1. Unscrew cover. Keep threads clean and free
from damage.
2. Switches are set at factory when in
counterclockwise position. Index marks should
appear as shown (Mark 1 only). Set screws, or
holes in manual cams, (#2, 4 and 6) on Closed
switches will be directly above index marks.

#1,3,5 Open #2,4,6 Closed
3. Attach appropriate Drive Yoke onto two pins
using a #6-32 screw provided. (Note: Coupling is a
special spring temper yoke or solid metal block. Do
not attempt to fabricate your own yokes.)
4. Attach mounting bracket (127-003 is shown) to
switch housing using 1/4˝ screws provided.
5. With actuator shaft rotated to its
counterclockwise position, spread the Drive Yoke
and slip it down onto the square (or rectangular) part of the actuator shaft. 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 in
complete stroke. Adjust position as required, and tighten all the mounting screws. Check
concentricity and perpendicularity. Readjust per above steps as necessary.
ADJUSTMENT PROCEDURE
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 loosening the set screw. To adjust manual
cams, grasp cam on knurled segment of cam surface. Simply rotate the cam on spline
attached to the shaft. Feeling or sound of clicks indicates 6º incremental adjustments. Stop
rotating and release pressure on cam when it is at proper actuation point. This allows cam to
engage spline. Check the circuit to verify contact at proper point. Rotate shaft. Repeat steps

INSTALLATION PROCEDURE
1. Attach proper mounting bracket to switch housing using screws provided. Tubular spacers
are provided for some installations.
2. Attach appropriate driving lever onto shaft. Do not tighten.
3. Attach switch and bracket to actuator, making sure that lever is free to rotate over entire
range of actuator stroke.
4. Attach driving pin or bolt through lever arm if slotted, or on driving side of solid lever. (It may
be necessary to loosen or remove mounting bracket to accomplish connection on some
actuators.)
5. Operate 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 most desirable position. When
all motions are made and clearances are adequate, tighten clamp screw on lever that was
left loose in step 2. Tighten all mounting screws. Recheck the travel of all levers and pins for
proper clearance through the entire stroke of the actuator.
6. Unscrew cover. Keep threads clean and free from damage. Index marks
are imprinted into driven magnet collar as shown (Mark 1 only). Set screws or holes in
manual cams (#2, 4 and 6) will be directly above index marks on those switches that are
Closed. Marks must be in line when making switch cam adjustments. Cams are set at
factory when in the counterclockwise position, as shown, and listed as follows:

#2 Closed
4 Switch Unit
#1, 3 Open
#2, 4 Closed
6 Switch Unit

ADJUSTMENT PROCEDURE
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 indicate incremental adjustments.
Applying pressure on cam in direction of protruding actuation segment of cam surface, and
rotating, eliminates incremental adjustments. Stop rotating and release pressure on cam
when at proper actuation point. This allows engagement of cam to spline. Check circuit to
verify contact at proper point. Repeat the cam adjustment steps as necessary. Lock manual
cam on spline with set screw provided for additional security.
B. Operate actuator to opposite extreme (full Open), and adjust cams to suit.
C. Screw on cover and tighten against o-ring seal until cover does not turn.

INSTALLATION PROCEDURE
Mount the switch as necessary, concentric and perpendicular over the rotating shaft that is to
be monitored. Direct drive yokes are available in many widths and lengths to fit your needs
(Yokes are fabricated from spring temper stainless steel. Do not attempt to fabricate your own
yokes.) Shaft drive units require an appropriate coupling (flexible type recommended) to the
shaft being monitored.

Remove cover by unscrewing. Take care to keep threads clean and free from damage.
Clockwise rotation of the yoke or shaft will move the bar up, counterclockwise moves it
down. Switches are set at the factory for approximately one revolution of the yoke or shaft
to actuate switch #1. Notice, that the cam screw for switch #1 is in location E. By changing
that cam screw to location D, three additional revolutions of the yoke or shaft will be
required to actuate #1 switch. Moving the cam screw to holes C, B or A will add three
revolutions for each location moved, until 13 revolutions are required between switch #1
and 2 actuation.
The cam screw for switch #2 in location A. By moving it to location B, C, D, or E, three
revolutions are added for each location change.
Rotate the switch slowly through the full cycle several times before tightening the bolts
securely. Observe the rotation for signs of yoke or shaft misalignment or binding with the
actuator shaft. Correct as necessary, then tighten the mounting bolts and recheck
alignment.

INSTALLATION AND ADJUSTMENT
1. Attach the switch to the actuator or valve. Refer to Installation
and Adjustment Instructions:
p. 9 for Direct Drive Mark 1 and 4 Models
p. 10-11 for Lever Drive Mark 1 and 4 Models
p. 12-13 for Mark 3 Models
2. Remove cover by unscrewing. Take care to keep threads clean and free from damage.
3. On models 13XXX and 43XXX, the switches are set at the factory when in the
counterclockwise position as shown. Switch #1 is open, and #2 is closed. When cams are
rotated 90º clockwise, #1 becomes closed and #2 is open. The cams may be adjusted to
increase or decrease the 90º rotation. For model 33XXX refer to pages 12 and 13 for Switch
Adjustment Procedure.
4. The potentiometer is positioned at the factory with the resistance element approximately
centered. The resistance readings in the chart are typical of each different potentiometer.
5. To adjust the potentiometer to a different range, loosen the two lower set screws on the
coupling. While holding the cams in the desired position, rotate the coupling and potentiometer
shaft to the preferred location. Rotating clockwise reduces resistance between pins 2 and 1,
and increases resistance between 2 and 3. Rotating counterclockwise increases resistance
between pins 2 and 1, and reduces resistance between 2 and 3. If the resistance “jumps”
rapidly, the pot is improperly rotated and functioning in the 20º dead area. Retighten the 2 set
screws. A 2K span adjustment pot is provided, to activate move bypass shunt to the other pin.

Models 15XXX, 35XXX and 45XXX Rotary Position Indicating Switches contain a 4-20 mA
Transmitter and two Single Pole Double Throw (SPDT) Micro switches. Models 150XX, 350XX
and 450XX contain a 4-20 mA transmitter only, no switches.
• 4-20 mA output is fully adjustable for various rotations (zero and span). See chart above
for rotation ranges using various potentiometers.
• 4-20 mA circuit is supply reversal protected and thermal protected.
• Clockwise or counterclockwise rotation corresponding to increased current output can
conveniently field selected with plug connector.
INSTALLATION AND ADJUSTMENT
1. Attach the switch to the actuator or valve. Refer to Installation and Adjustment instructions:
p. 9 for Direct Drive Mark 1 and 4 Models
p. 10-11 for Lever Drive Mark 1 and 4 Models
p. 12-13 for Mark 3 Models
2. Remove cover by unscrewing. Take care to keep threads clean and free from damage.
3. On models 15XXX and 45XXX, the switches are set at the factory when in the
counterclockwise position as shown. Switch #1 is open, and #2 is closed. When cams are
rotated 90º clockwise, #1 becomes closed and #2 is open. The cams may be adjusted to
increase or decrease the 90º rotation. For model 35XXX refer to pages 12 and 13 for Switch

4. The potentiometer is positioned at the factory with the resistance element
approximately centered.
CALIBRATION
A. Set the valve at the position where you want the meter to read 0% (that is 4 mA). It may be
necessary to move the plug connector to change the direction of current output to increasing
for clockwise rotation or vice versa.
B. On models 15XXX, loosen the two bottom set screws on the coupling. Rotate the coupling
and potentiometer shaft to the position where the meter reads 0% (4 mA). Tighten two set screws.
C. Turn valve to opposite position where meter should read 100% (20 mA). Use small
screwdriver to adjust the blue rectangular potentiometer "span" until 100% (20 mA) is on the
meter. If it is not possible to reach 100%, refer to Troubleshooting instructions.
D. Return valve to original position at 0% (4mA). Use small screwdriver to adjust "zero" turning
until 0% (4 mA) is read on meter. Repeat steps C & D until 4 and 20 mA read consistently
on each end of stroke.
TROUBLESHOOTING
I. If no current flows, check polarity of current loop (plus and minus screws on terminal strip).
Also check loop resistance for open line.
II. If full output current cannot be achieved by adjustment, voltage at transmitter may be too
low. If so, increase power supply voltage until a minimum of 15 volts is registered or move
voltage shunt to 12 VDC.
III. If current increases and decreases in the wrong direction, move the plug Connector from
CW to CCW or vice versa.
IV. Check specs to make sure you are in range of adjustment, (See chart on previous page).
V. If the zero adjustment does not have enough range, the zero must be mechanically realigned
as follows: Set the “zero” (fine 4 mA) adjustment to the middle of its range. (Full multi-turn
range is 25 revolutions; set at 12-1/2 revolutions.) Repeat calibration steps B, C and D.

CIRCUIT BOARD FEATURES
• Two test points are provided as a convenience for attaching a HART® communication master.
• The WP (write project) shunt enables and disables the ability to change configuration
settings. It can prevent unintended configuration changes from an accidental press of the
ZERO or SPAN button and from communications with a HART® communication master. Set
this shunt to ON to prevent configuration changes. Set this shunt to OFF to allow
configuration changes.
• The FAULT shunt determines whether the transmitter fails high or low in a fault condition.
When set to high the transmitter will output 21.0 mA in a fault condition. When set to low the
transmitter will output 3.6 mA in a fault condition. The transmitter will output 3.8 mA and 20.5
mA when operating normally.
• The FIND shunt determines if the transmitter will respond to a FIND command. When set to
ON the transmitter will respond to a HART® communication master’s Find Command. When
set to OFF the transmitter will ignore FIND commands. This is useful for allowing a HART®
communication master to discover the transmitter.
• The LED will flash in response to a HART® communication master’s Squawk Command. This
is useful for identifying a transmitter attached to a HART® communication master.
