Single phase actuators range in complexity from simple models with basic operability, to quite complicated
models with battery backup and local control capabilities. The various models might seem to be easily adaptable
across any site or design intent, but are actually very specic a s to h ow they i nterface t o e xisting o r n ew
installations. It is important to FULLY UNDERSTAND what level of control is required prior to selecting one of
these products. While it might make sense to opt for the most feature-laden solution in order to cover all the
possibilities in a given application, that selection in fact would NOT function in an application that just required
the most basic unit.
Notice: Read the project specications and understand the application before making an actuator selection. If
in doubt, consult with the project engineer to clarify what is actually required for a fully operational installation.
We have provided in this document all the tools necessary to determine how the various levels interface to
the outside world. If there are any questions, please contact Flo-Tite.
Notice: HRSN3 Series actuators are fully assembled, calibrated and tested prior to leaving our factory. In most cases, after
you have mounted the actuator to your device, you should be able to operate the actuator from fully CLOSED (CW) to fully
OPEN (CCW) and back again, and nd that no adjustments are needed. The assembly can be put into service immediately.
However, should it be necessary to make adjustments to the end-of-travel positions to overcome any device related issues
(i.e. valve shaft incorrectly timed to the drive stem), the procedures outlined below should be followed to put the assembly
into service. Note that there is a maximum adjustment range of +/- 3° at each end of travel.

2. Storage: This unit should not be stored outside unless it is powered up and
has proper conduit terminations. When not powered up, it should be stored
in a clean, dry environment at all times.
3. This quarter-turn actuator has been factory tested and calibrated to operate
between 0° and 90°. Most products will not require recalibration of these
settings. If any travel adjustment is necessary, please refer to the Adjusting
CW/CCW End of Travel section for instructions.
4. Notice: The Series actuators have mechanical stops which limit
rotation. Do not attempt to operate with a rotation greater than 95°.
5. Notice: Protect the actuator from moisture by installing it with water tight
EMT ttings and proper conduit drainage. Supply power to the unit to keep
the internal heater warm at the time of installation.
SHIPPING AND HANDLING
INSTALLATION NOTES
The actuator has a red and green position
indicator. RED color in the indicator
window means the actuator is fully
CW, while GREEN means it is fully CCW.
The manual override handwheel
allows a user to position the valve or
damper with or without power. Turn
the handwheel CW to make the output
drive move CW (when viewed from
above). Turning the handwheel CCW
makes the output drive turn CCW.
WARNING – To avoid dangerous or fatal electrical shock,
turn OFF power to all electrical equipment
before working on electrical connections.
CAUTION – Please follow the following guidelines for proper installation.
•These actuators are designed to be used between a horizontal and
upright position. Do NOT mount the assembly with the actuator top
below a horizontal position (i.e. upside down).
•When installing conduit, use proper techniques for entry into the actuator.
Use drip loops to prevent conduit condensate from entering the actuator.
• Mechanical travel stops are factory calibrated for 90 degree operation.
These stops are NOT designed to adjust mechanical rotation by more
than +/- 3 degrees, they are for positioning the handwheel only.
• Both EMT conduit ports MUST use proper equipment to protect the
NEMA 4X integrity of the housing.
• The internal heater is to be used in ALL applications.
•Do NOT install the actuator outdoors or in humid environments unless it
is powered up and the heater is functioning.
• Use proper wire size to prevent actuator failure (see Wire Sizing Chart for
proper wire sizing).
• All terminals accept 12-18AWG solid/stranded wire.
•Notice: Do NOT parallel wire multiple on/off actuators together without
utilizing isolation relays. If this is your intention, please contact Flo-Tite for
a multiple actuator parallel wiring diagram.

1. Fully CLOSE the valve or damper to which the actuator is to be mounted.
2. Assemble necessary linkage hardware and attach the actuator to the valve
or damper.
3. Center the actuator on the valve or damper drive shaft and tighten all hardware.
4. Before applying power to the unit, rotate the manual override handwheel
from the fully CW to the fully CCW position to check for unobstructed manual
operation of the valve or damper.
5. Series actuators utilize a removable terminal block to simplify eld
wiring and testing.
•To remove a terminal block from the PCB receiver, pull straight out in a
direction parallel to the PCB.
•In the photo at right, the RIGHT side of either terminal block (between the
PCB mounting screws) is pulled out to the RIGHT.
•After wiring, reinsert the terminal strip into the receiver.
This is a keyed pair and can only be inserted one way.
•Screw terminals are rated to accept 14AWG down to 18AWG solid or
stranded wire. TERMINAL NUMBERING HAS #1 AT THE BOTTOM.
6. Refer to your product part number to determine which wiring diagram to
follow when wiring up the actuator.
7. Note that although terminals are labeled as 1-8 and A-D, not all terminals are
used on all models.
Removable terminal blocks facilitate
ease of eld wiring and testing.To
remove a terminal block from the PCB
receiver,pull straight OUT in a direction
parallel to the PCB. Use caution
when reinserting block - make sure
all pins are aligned before seating.

Notice: Torque switches are factory set and are not adjustable.
8. Make the electrical connections per the appropriate Wiring Diagram for
your actuator.
9. Connect POWER and CONTROL to the correct terminals.
10. Terminals A~D on each actuator are for the (adjustable) auxiliary switches.
These are dry type (volt free) Form A contacts rated 250VAC @ 10A Max.
11. Select actuators covered in this manual are equipped with torque switches
which protect the actuator motor and gear train. Torque switches protect
controlled valves or actuators from damage in the event of a high torque
condition. More information can be found throughout this manual.
Notice: All HRSN3 Series actuators rotate CW to close the output shaft
out the bottom of the actuator when viewed from above. On all HRSN3
models, the cam shaft and the indicator rotate CW to close as well.

Torque Switch Operation
Select HRSN3 units have torque switches to protect the actuator and any attached equipment from possible damage
which can occur in a high torque event. In such an event the valve or damper being driven encounters some blockage
or impediment to travel. In the case of an actuator without torque switches, the actuator will attempt to drive until it

CAUTION! - The mechanical
stop screw limits handwheel
operation ONLY and is NOT to
be used as an electrical travel
limiting device.
This actuator has been factory calibrated and tested to stop at 0 degrees for CW position and to stop at 90 degrees
for CCW position. Most installations onto valves or dampers will likely not require recalibration of these settings. Please
mount the valve or damper and proceed on these pages only if adjustments are required. Note that for most actuators
these positions are independent - for instance the CW position is accurate while the CCW position might need adjustment.
WARNING – Serious Damage to the actuator will result if the motor is allowed to drive the gear train into the
mechanical stop! Remove power from this device BEFORE making any travel adjustments.
Reposition Mechanical Stop
1. Disconnect power.
2. Loosen the RIGHT SIDE mechanical stop. This is the CW mechanical stop
limit adjustment. Using a 17mm wrench and a 5mm hex key, hold the jam
nut and turn the stop screw 5-6 turns CCW so it clears the mechanical boss
inside the actuator.
•This will allow you to adjust the cam/switch stop position
without running into the mechanical stop screw.
3. Use the manual override handwheel to position the actuator to your required
CW position. Keep all changes within +/- 3 degrees of the factory setting.
Adjust CW Cam (Bottom)
4. Cam 1 is the bottom cam (red) and is the end-of-travel adjustment for the
actuator CW position. With POWER OFF and the actuator at its required
CW position, use a sharp 2.5mm hex key to free up the cam set screw.
Take care not to let the hex key slip at this stage, it can easily strip out.
Once it is free adjust it as described below:
•Rotate the hex key to the RIGHT 10-15
degrees until you hear a click. This will
reset the switch roller arm.
•Gently tighten (CW) the set screw only
until slight pressure is felt. Ideally the
set screw rides along the camshaft.
•Now SLOWLY rotate the hex key to the
LEFT, pushing the cam, until you hear
the “click” on the bottom switch. The
click means correct adjustment has
been achieved.
•Tighten the cam set screw.
5. Apply power and test for the correct CW position:
•Drive the actuator CCW at least 15-20 degrees.
•Drive the actuator CW until the cam stops the electrical travel.
•Check to be sure this is the correct CW position you require.
Repeat the steps of item 4 if further adjustment is needed.
Tighten Mechanical Stop
1. With the actuator in the proper position. Hold the 17mm wrench on the
RIGHT SIDE jam nut to prevent the jam nut from locking and turn the 5mm
hex key CW until the end of the stop screw bottoms out against the internal
stop boss.
2. Turn the hex key ONE FULL TURN CCW and lock this position with the jam
nut. Now the actuator will reach its end of travel electrically before there is
any interference from the mechanical stop.
3. CW position calibration is now complete.

Cam 3 - CW Auxiliary Cam
Cam 4 - CCW Auxiliary Cam
Adjust CW Auxiliary Cam
1. Cam 3 is the third cam up from the bottom (red) and is the CW auxiliary
switch adjustment, an optional switch typically used to indicate the actuator
reached its CW position.
2. Drive the actuator to its CW position. Use a sharp 2.5mm hex key to free up
the cam set screw. Take care not to let the hex key slip at this stage, it
can easily strip out. Once it is free adjust it as described below:
•Rotate the hex key to the RIGHT 10-15 degrees until you hear
a click. This will reset the switch roller arm.
•Gently tighten (CW) the set screw only until slight pressure is
felt. Ideally the set screw rides along the camshaft.
•Now SLOWLY rotate the hex key to the LEFT, pushing the cam,
until you hear the “click” on the bottom switch.
•Continue to rotate the cam between 3 and 5 degrees to the
LEFT to make sure the auxiliary cam switch changes state
before the actuator reaches its end of travel electrically.
•Tighten the cam set screw.
Adjust CCW Auxiliary Cam
1. Cam 4 is the fourth cam up from the bottom (green) and is the CCW
auxiliary switch adjustment, an optional switch typically used to indicate
the actuator reached its CCW position.
2. Drive the actuator to its CCW position. Use a sharp 2.5mm hex key to free
up the cam set screw. Take care not to let the hex key slip at this stage,

The end stop travel (cams) of this actuator have been factory set and tested to respond between 0° and 90°
degrees rotation. If NO changes to end stops are required, this unit is ready to be put into service immediately
using this procedure. IF changes to the cam positions are required, refer to pages 8 ~ 10 before proceeding.
WARNING – Serious Damage to the actuator will result if the motor is allowed to drive the gear train
into the mechanical stop! Remove power from this device BEFORE making any travel adjustments.
WARNING – Follow these directions carefully and in order. Actuator damage due to improper testing
and commissioning will NOT be covered under warranty.
Calibration Procedure - On/Off Control
1. Apply correct power according to the actuator model, referring to wiring diagrams.
2. Position the actuator to its full CCW (Open) and/or CW (Closed) positions and adjust the cams as necessary.
3. After making cam adjustments on either or both ends of travel, it is advisable to move off cam slightly, and then
repeat the drive command to assure the cam settings are correct.
4. Be sure the cam setscrews are snug (overtightening during calibration will make it difcult to make minor
incremental adjustments).
5. Unit is now calibrated and is ready to be put into service. No other calibration is necessary.
Commissioning Procedure - On/Off Control
1. Utilize the handwheel or override shaft to rotate the actuator and damper, valve or other connected device through
its full travel from full CW to full CCW and back again to check for any possible interference. Do NOT utilize any
mechanical advantage devices to rotate the handwheel (pipes, wrenches, extension bars, etc.).
2. Manually position the actuator to its mid-stroke position.
3. Apply correct power to the unit.
4. Measure correct power and polarity on terminals 1 & 2 AT THE MAIN TERMINAL BLOCK.
5. Command the eld device to generate a CCW signal. The actuator rotates in a CCW direction (as viewed from above).
6. Measure terminals 2 and 6 (Run CCW) for correct voltage (matching that measured in step 4).
7. Actuator will stop when it reaches it’s full CCW position.
8. With eld command signal still present, measure terminals 2 and 5 and read voltage to match that measured in
step 4.
9. Read continuity between terminals C & D to show the CCW Aux switch is closed.
10. Command the eld device to generate a CW signal. The actuator rotates in a CW direction (as viewed from above).
11. Measure terminals 2 and 4 (Run CW) for correct voltage (matching that measured in step 4).
12. Actuator will stop when it reaches it’s full CW position.
13. With eld command signal still present, measure terminals 2 and 3 and read voltage to match that measured in
step 4.
14. Read continuity between terminals A & B to show the CW Aux switch is closed.
15. Generate a mid-position signal at the eld device to move the actuator off its full CW trip position.
16. Return Field control to automatic mode.
17. Actuator is now commissioned and operational.

Symptom Target Action
Actuator does
not move when
commanded
to do so.
Power Source Measure incoming power AT the actuator terminal block.
Reference the correct wiring diagram.
Control Problem
Generate move commands by the eld device. Measure correct
voltage changes between HOT and terminal #6 (CCW) and HOT
and terminal #4 (CW).
Wire Sizing Check for correct wire size per Wire Sizing Chart.
Supply and
controls are
measured to
be correct, but
actuator still does
not move.
Overtorque
Remove the actuator from the driven device. If the actuator now
moves, the torque required by the mechanical device exceeds
that of the actuator. Increase actuator size.
With the actuator removed from the mechanical equipment,
manually rotate the valve or damper through its intended range
of travel to check for mechanical problems.
Insufcient power
supply and/or
incorrect wire size
during installation.
Measure the voltage between terminals 1 & 2 WHILE
commanding the actuator to move. The measured voltage
cannot drop more than 10%.
Cams improperly
set.
REMOVE POWER. Check to see if cams rotate freely on the
cam shaft using your nger. Cams MUST be secure and set
according to the procedures in the Adjusting CW/CCW End of
Travel section.
Motor is extremely
hot to the touch.
Control “noise” or
excessive duty cycle
Check for stray voltage fl uctuations on the incoming control
signals. The on/off line voltage actuators have a maximum 25%
duty cycle. While the low voltage models have a 75% duty cycle.
Check for parallel wiring of multiple on/off actuators. Review the
site as-built wiring diagrams to verify.
Actuator does not
stop at correct
position at either
end of travel
Travel cams and/or
mechanical stops not
positioned correctly
Reset end-of-travel cams and/or mechanical stops as detailed
in the Adjusting CW/CCW End of Travel section.
After completing all mounting and wiring procedures and main power is available, if the actuator does NOT respond
as expected, the following procedure(s) may help in identifying the problem.
WARNING – To avoid dangerous or fatal electrical shock, turn OFF power to all electrical
equipment before working on electrical connections. If it is necessary to
troubleshoot with live power to the actuator, please use EXTREME CAUTION,
and follow your company's safety protocols and procedures at all times.

Symptom Target Action
Actuator does
not move when
commanded
to do so.
Power Source Measure incoming power AT the actuator terminal block.
Reference the correct wiring diagram.
Control Problem
Generate move commands by the eld device. For most analog
control systems, reversing the polarity will render the control
system output as invalid. Check the polarity of the analog control
signals as they are connected to the actuator. The actuator will
NOT respond to inverted control signals.
Wire Sizing Check for correct wire size per Wire Sizing Chart.

Control “noise” or
excessive duty cycle
Check for stray voltage uctuations on the incoming control
signals. Analog control signals are succeptable to “noise” and
send unstable control data to the actuator. This results in a
never-ending motor drive scenario with the usual result being
thermal overload of the drive motor.
Check for parallel wiring of multiple on/off actuators. Review the
site as-built wiring diagrams to verify.
Actuator does not
