1.6 Safety precautions
2 MOUNTING
1. Attach mounting plate to actuator using fasteners
and lockwashers provided.
2. Loosen indicator cover set-screw.
3. Rotate indicator cover to desired viewing angle and
retighten set-screw. (Make sure indicator cover is
pushed all the way into housing slot.)
4. Rotate coupling spacer and indicator drum to
desired position. (OPEN or CLOSED appearing
through indicator window.)
5. Remove spacer screw and fit reinforcer and cou-
pling into coupling spacer or Namur coupling. Sep-
arate spacer and indicator drum and rotate spacer
to align coupling with actuator shaft. Fit coupling
spacer over indicator drum drive hub.
6. Secure torque coupling assembly or Namur cou-
pling with screw of proper length. (Additional cou-
pling spacers and longer screw may be required on
some mountings.)
7. Slide Thru-Bolts with washers into housing and fit
retaining quad-rings over bolts to retain them.
8. Top of actuator shaft should be within 6.35 mm (1/4")
from torque coupling screw head or Namur coupler.
9. Torque coupler or Namur coupler must be fully
engaged in slot and be centered on the shaft or
block attached to the shaft.
10.Operate actuator to full open and full closed posi-
tions and check for proper alignment between
switch and actuator. Eccentricity of shaft must not be
greater than 0.25 mm (0.01") from centerline. The
torque coupler or Namur coupler must be centered
on the flats of the actuator shaft or block in both the
full open and full closed position. Realign as neces-
sary and final tighten Thru-Bolts.
11."Fine-tune" visual indicator cover repeating steps 2
and 3 and lightly tighten set screw.

3 ADJUSTING
3.1 Touch & Tune™ switch setting
Notes: All adjustments assume you are looking down on
the top of the sensors. The edge of the cam metal strip
will be at the edge of the sensor target when activation
occurs. When the cam is released be sure it slides fully
onto the spline. One spline tooth setting is 4 1/2°.
Types 33, 93, 96, 97
I. For Normally Open function, Fig. 4
1. With the valve in the "Closed" position and if the
valve turns counter-clockwise to open, set both
cams so that the metal activation strips are 180°
from each other with the bottom cam set in the mid-
dle of the sensor target.
2. Lift the bottom cam and turn counter-clockwise until
the red LED goes "out" then clockwise again until the
red LED just comes "on". Reverse the direction of
the cam if the valve opens clockwise. (2* in Fig. 3).
3. Move the valve to the opposite position (Open),
push down on the top cam and rotate counter-clock-
wise until the green LED just comes "on". Reverse
the direction of the cam if the valve opens clockwise.
(3* in Fig. 3).
For the normally open operation, both LEDs will be off
during the actuation period. If the optional green
"Closed" visual indicator is used the colors would be
reversed in I and II.
II For Normally Closed function, Fig. 5
1. With the valve in the closed position, set both cams so
that the metal activation strips are aligned with each
other and set in the middle of the sensor targets.
2. If the valve turns counter-clockwise to open, pull up

Connect a load resistor of 3 kΩto 10 kΩacross a
switch’s Load and (+) terminals (QN2E, QX2E), or a
switch’s Load and (-) terminals (QN2F, QX2F). Using a
24 V DC power source, connect the power source (+)
lead to a switch’s (+) terminal and the power source (-)
lead to a switch’s (-) terminal. Connect a voltmeter
across the load resistor. Apply 24 V DC. With cam acti-
vation strip in front of sensor target, the voltmeter will
read >20 V DC.
Activation strip away from sensor target voltmeter will
read 0 V DC.
Warning: Connecting the switch to a power source
without a load resistor may result in irreparable dam-
age to the switch.
3.3.4 Type 44
Use StoneL Light Read Tester or use a 24 V DC power
supply.
No series load resistor required.
3.3.5 Types A, N
Use StoneL Light Read Tester or use a 12 V DC power
supply and an ammeter.
No series load resistor required.
3.3.6 Types P, L, G, H, S
Test LED units with 9 volt battery and series load resis-
tor between 150 and 1000 Ω- 1/2 W. Ohm meter will not
work. (Light Read tester available from StoneL or
StoneL distributor.)
Minimum of 3.5 V required for proper switch operation.
3.3.7 Type 93
Use 9 to 32 V DC power supply across FB + and FB -.
No series resistor needed. To test communication, a
functioning Foundation Fieldbus network is required.
3.3.8 Types 96, 97
To Bench Test AS-Interface Module: Use 24 V DC
power supply across ASI + and ASI -. No series resistor
needed. To test communication, a functioning AS-Inter-
face network is required.
Do not apply external power to output terminals.
WARNING:
Failure to use a series load resistor when bench
testing sensors with a power supply will result in
permanent damage to the unit.
