3. 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.

4. This actuator has been factory calibrated to operate between 0° and 90°. Most quarter-turn products will not require recalibration of these settings. If any travel adjustment is necessary, please refer to pages 11-12 for instructions.

5. NOTICE: The standard HRSN3 series actuator CANNOT operate with a rotation greater than 95°.

Shipping and Handling

Product Mounting and Setup

• 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.

• 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 NPT 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 chart on page 4 for proper wire sizing).• All terminals accept 12-16AWG solid/stranded wire.• NOTICE: Do NOT parallel wire multiple on/off actuators together without utilizing isolation relays. If this is

your intention, please contact HAYWARD FLOW CONTROL for a multiple actuator parallel wiring diagram.

Installation Notices:

The actuator is shipped from the factory in its fully CW (CLOSED) position. RED color in the indicator window means fully CW, while GREEN means fully CCW.

5. HRS Series actuators utilize a removable terminal block to facilitate ease of field wiring and testing. To remove the 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 the 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. (reference the correct wiring diagrams for numeric sequencing).

6. 6. Note that although terminals are labeled as 1-8 & A-D, not all terminals are used on

all models. Be sure to make field connections to the proper terminal as identified by the LABEL and not the position!

7. Make the electrical connections per wiring diagrams found on pages 4~9. 8. Connect POWER and CONTROL to the correct terminals.9. Terminals A~D on each actuator are for the (adjustable) aux switches. These are dry

type (volt free) Form A contacts rated 250VAC @ 10A Max.

(con’t from pg 3)

Wire sizing data is provided in the table below to assist in the selection of the proper wire size for Hayward HRSN4 Series actuators using various wire sizes over distance. Be make sure to reference the correct voltage and do not exceed the indicated length of the wire run for each model.

CAUTION! - The mechanical stop screw limits handwheel operation ONLY and is NOT to be used as an electrical travel limiting device.

WARNING – Serious Damage to the actuator will result if the motor is allowed to drive the gear train into the mechanicalstop!!RemovepowerfromthisdeviceBEFOREmakinganytraveladjustments.

Loosen Mechanical Stop1. BEFORE power is applied, use a 17mm wrench and a 5mm hex key

to loosen the RIGHT SIDE mechanical stop. This is the CW stop limit adjustment. Turn the stop screw 5-6 turns CCW to allow electrical cam stop adjustment without running into the mechanical stop screw.

2. Use the manual hand wheel to position the actuator to your required CW position. This must be within +/- 3 degrees of the factory setting.

Adjust Cam 1 3. The lower cam is Cam 1, the CW end-of-travel adjustment. With the

actuator at its required CW position, with POWER OFF, use a 2.5mm hex key to free up the cam set screw. Once it is free, rotate the hex key to the RIGHT 10-15 degrees to reset the switch roller arm. Then snug the set screw up against the camshaft (CW) until slight pressure is felt. Now SLOWLY rotate the hex key pushing the cam to the LEFT until you hear the “click” on the bottom switch, indicating that correct adjustment has been achieved. Tighten the cam set screw.

4. Apply power to the actuator and drive CCW at least 15-20 degrees. Then drive the actuator CW until the cam stops the electrical travel. Check to be sure this is the correct CW position you require. Repeat step 3 if further adjustment is needed.

Tighten Mechanical Stop5. While holding the 17mm wrench on the RIGHT SIDE jam nut to prevent

the jam nut from locking, turn the 5mm hex key CW until the end of the stop screw bottoms out against the internal stop boss. Then turn the hex key ONE FULL TURN CCW before locking that adjustment with the jam nut. This procedure assures that the actuator reaches its end of travel electrically before there is any interference from the mechanical stop.

6. This completes the CW position calibration.

This actuator has been factory calibrated to operate between 0 degrees and 90 degrees. Most quarter-turn products will not require recalibration of these settings. Proceed ONLY if adjustments are required.

Calibration Procedure - On/Off Control:1. Before making any changes in this section, keep in mind that this actuator has been fully calibrated 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. IF changes to the cam positions are required, refer to pages 11 ~ 13 before proceeding.

2. Apply correct power according to the actuator model, referring to wiring diagrams on pages 4~9.3. Position the actuator to its full CCW (Open) and/or CW (Closed) positions and adjust the cams as necessary.4. 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.5. Be sure the cam setscrews are snug (overtightening during calibration will make it difficult to make minor incremental

adjustments).6. Unit is now calibrated and is ready to be put into service. No other calibration is necessary.

Calibration and Commissioning Procedure - On/Off Control (All Models)

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 actuator terminal block.5. Command the field 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 field 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 field 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 field command signal still present, measure terminals 2 and 3 and read voltage to match that measured in step 4.14.

PCB Referance Data

All HRSN3 Series utilize a main terminal block where ALL field connections are made. This is a 12 position removable terminal block.

There are no other PCB’s installed inside a 120vac or 230vac On/Off actuator.

On HRSN3 Series 24vac and 24vdc On/Off units, a second PCB is installed which is the logic and switching board controlling the drive motor. There are no user adjustments on this board. However there are interface headers and set-up trimmers that are factory set and should not be adjusted.

On HRSN3 Series 120/230vac proportional models, a logic/drive control PCB is installed inside the enclosure.

And on HRSN3 Series 24vac/vdc proportional models, this logic/drive PCB is installed inside the enclosure. AC models also have a full wave bridge attached to the top gear plate to provide the required DC voltage for the drive motor.

Calibration Procedure - Proportional Control (120/230vac Models):

After completing all mounting and wiring procedures and main power is available, it is now possible to commission the actuator. 1. Before applying power or making any wiring connections:2. Set the geartrain in the full CW position.3. Set the #1 and #3 cams according to the on/off procedure.4. Set the unit in the full CCW position. 5. Set the #2 and #4 cams according to the on/off procedure.6. Set the geartrain back to the fully closed (CW) position.7. Make your field wiring connections for power, control and feedback signals, referring to the correct wiring diagrams on

pages 4~9. a. Connections are made ONLY TO THE MAIN TERMINAL BLOCK. b. No connections are made to the proportional control board directly.8. Set the jumper headers for correct signal IN and OUT. (ref pg 17)9. Rotate the potentiometer pinion gear to its full CCW position, then back about 1.5~2 teeth CW before tightening the

two M3 setscrews on the sector drive gear.10. Apply correct power according to the actuator model. a. The red PWR LED will turn on.11. Press the “Calibrate” black pushbutton on the Mod control board and hold it down for about three seconds, then

release. a. The unit will run to its full CCW position, stop for a few seconds, then run back to its full CW position. 12. After a few seconds, the unit will complete the calibration routine and will return to active operation mode by responding to the incoming 4-20mA control signals being sent to the actuator.13. Slight adjustments may be made to the 4mA and 20mA trimmers to affect accuracy on the feedback signal as a function of actuator position.14. Unit is now calibrated and is ready to be put into service. No other calibration is necessary.

Alignment of the sector and potentiometer gear sets at actuator full CW position. (ref step 9).

Commissioning - Proportional Control ActuatorsAfter completing all mounting and wiring procedures and main power is available, it is now possible to commission the actuator.

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 actuator terminal block.5. Command the field device to generate a 20mA (10vdc) signal. The actuator OUTPUT shaft rotates in a CCW direction (as

viewed from above) and stops at the full CCW (Open) position.6. Measure terminals 5 (+) and 6 (-) to read 20mA (10vdc).7. Read continuity between terminals C & D to show the CCW Aux switch is closed.8. Command the field device to generate a 4mA (2vdc) signal . The actuator OUTPUT shaft rotates in a CW direction (as

viewed from above) and stops at the full CW (Closed) position.9. Measure terminals 5 (+) and 6 (-) to read 4mA (2vdc).10. Read continuity between terminals A & B to show the CW Aux switch is closed.11. Generate a 12mA (6vdc) signal at the field device to move the actuator to its mid-travel position.12. Actuator stops at 50% travel, and feedback measuers 12mA (6vdc) +/- tolerance error if any (single decimal). 13. Return Field control to automatic mode. Actuator is now commissioned and operational.

Troubleshooting - On/Off ActuatorsIf, after completing all mounting and wiring procedures and main power is available, the actuator does NOT respond as expected, the following procedure(s) may help in identifying the problem.

Symptom Target Action

Actuator does not move when commanded to do so.

Power Source Measure incoming power AT the actuator terminal block.

Control ProblemGenerate move commands by the field device. Measure correct voltage changes between terminals 2 and 6 (CCW) and between terminals 2 and 4 (CW).

Wire Sizing Check for correct wire size per table on Pg 10.

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.

Insuffucient 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 finger. Cams MUST be secure and set according to the procedures on pages 11 ~ 13.

Motor is extremely hot to the touch.

Control “noise” or excessive duty cycle

Check for stray voltage fluctuations 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

Actuator is out of quadrant (HRSN2A, 2R ONLY)

The manual override system has been employed to rotate the actuator beyond its intended angle of rotation. Use the manual override to rotate the actuator back into its correct quadrant of operation.

Travel cams not positioned correctly

Reset end-of-travel cams as detailed on pages 11~13

Troubleshooting - Proportional Control ActuatorsIf, after completing all mounting and wiring procedures and main power is available, the actuator does NOT respond as expected, the following procedure(s) may help in identifying the problem.

Symptom Target Action

Actuator does not move when commanded to do so.

Power Source Measure incoming power AT the actuator terminal block.

Control Problem

Generate move commands by the field 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 table on Pg 10.

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.

Motor is extremely hot to the touch.

Control “noise” or excessive duty cycle

Check for stray voltage fluctuations 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 DC drive motor.

Actuator does not stop at correct position at either end of travel

Actuator is out of quadrant (HRSN2A, 2R ONLY)

The manual override system has been employed to rotate the actuator beyond its intended angle of rotation. Use the manual override to rotate the actuator back into its correct quadrant of operation.
