5. N2 TO N5 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 4~7.
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.
Wire sizing data is provided in the table below to assist in the selection of the proper wire size for Siral N Series actuators
using various wire sizes over distance. Be make sure to reference the correct voltage and do not exceed the indicated

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
mechanicalstop!!RemovepowerfromthisdeviceBEFOREmakinganytraveladjustments.
Loosen Mechanical Stop
1. 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 Stop
5. 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 9 ~ 11 before proceeding.
2. Apply correct power according to the actuator model, referring to wiring diagrams on pages 4~7.
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 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.

PCB Referance Data
All N2 & N5 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 N2 & N5 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 N2 & N5 Series 120/230vac proportional
models, a logic/drive control PCB is installed
inside the enclosure.
And on N2 & N5 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.

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).

Calibration Procedure - Proportional Control (24vac/vdc 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 4~7.
a. Connections are made ONLY TO THE MAIN TERMINAL BLOCK.
b. No connections are made to the proportional control board directly.
8. Set the DIP switches 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 blue LED D1 will turn on, and grn LED STA will turn on.
11. Press the “SET” black pushbutton on the Mod control board and hold it down for about three seconds, then release.
a. The grn STA LED will turn off and the unit will drive to the fully CW position and stop when the pre-set cam
positions are reached. There are NO LED indicators to advise when the actuator is running.
12. When the actuator stops, press the CLO pushbutton ONCE.
c. The actuator will drive to its full CCW (Open) position and stop when the pre-set cam postions are reached.
13. When the actuator stops, press the OP pushbutton ONCE.
14. The unit will start to respond to the incoming 4-20mA control signal being sent to the actuator.
15. Slight adjustments may be made to trimmer VR2 if necessary to tune the feedback signal.
16. 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 Actuators
After 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 eld 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 eld 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 eld 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.
