3. VERIFICATIONS AND ACCEPTANCE
3.1 At acceptance, check that:
- the packaging is in good condition.
- the actuator is as ordered.
- the equipment is not damaged.
3.2 It is recommended to install the actuator as soon as accepted and not to leave it unused. If the
equipment has to be stored, it has to be in a dry place protected from weather.
4. PRECAUTIONS FOR OPERATION
4.1 Before installing, make sure that the installation is completely depressurized and brought to
ambient temperature.
4.2 In a zone classified as explosive, install only model SA05X.
Do not install this actuator in a marine environment and do not immerse it.
4.3 The actuator must not be electrically powered during the installation and maintenance of
the valve on the pipework, and of the actuator on the valve.
4.4 Before proceeding to the electrical connection, check the supply voltage of the actuator.
4.5 Do not mount the actuator in series or in parallel with other electrical motors. If need be
use relays.
4.6Do not mount the actuator on valves with higher torque than the nominal torque of the actuator.
4.7 Under normal operation: These motors have to be electrically controlled for opening or closing.
Spring driven return only takes places in case of power supply cut-off.
5. INSTALLATION ET UTILISATION
5.1 Install the actuator on the valve (already done for units assembled in our workshops)
5.2 Perform the electrical wiring as shown in the diagram below.
5.3 Adjust the switch stops (already done for units assembled in our workshops).
5.4 View the valve’s movement using the indicator light on the cover.

6. MANUAL INTERVENTION
CAUTION : Before any manual intervention, cut off the power supply, otherwise the SR actuator provided with
an electromagnetic clutch, can be damaged.
6.1 Put the hex wrench into the manual socket and turn to CW.
The lever shaft pops up and manual operation is available.
6.3 Put the lever shaft and turn the wrench to CCW it is switched to auto mode.
6.4 The declutch gear should go down to its original positon to restore the limit setting to factory set and pop
up using the hex wrench when resetting the limit positions.

7. STOP ADJUSTMENT
The return spring of the actuator becomes active in case of emergency stop (a power cut, e.g.)
In this case, spring stops have to be adjusted, using stop screws.
The SR actuator is protected when the stops are properly adjusted.
(carry out the adjustment of stops (screws) before adjusting the limit switches).
7.1 Manually place the actuator in the closed position after attaching it on top of the valve.
7.2 If the stops are incorrectly adjusted, the valve will not be in the fully closed position. In this case,
Adjust the stops to reach the fully closed position. Tighten the stops screws once the adjustment performed.
NOTA : Do not touch the adjustment already performed at the facility.
7.3 Adjust the stops in the same way as the stops in the closed position.
CAUTION : When the limit switch reaches the stop, the actuator works normally. Return to the initial position
when the actuator goes into fault.
The actuator works properly if the cams switch the limit switches before the stop plate reaches the screw. If the
actuator does not work properly, adjust the stop screws again.

8. SWITCH SETTING
Limit setting when electrical power isn’t supplied.
8.1 Put the hex wrench into the declutch gear and turn to CW. The declutch gear pops and manual operation
is available. The actuator remains the last position during the manual operation without holding the wrench.
Adjust limit cams with the hex wrench after mounting with the valve.
8.2 The declutch gear should go down to its original position to restore the limit setting to factory set and pop
Up using the hex wrench when resetting the limit positions.
Be sure to push the ASCN button to save the setting after limit setting.
Limit setting when electrical power is supplied
8.3 Position the declutch gear to the auto mode before limit setting.
8.4 Push the ZERO and SPAN buttons at the same time and check if the POWER and FAULT lamps turn on.
8.5 Limit setting by ZERO (closing) / SPAN (opening) buttons.
8.6 Push the ZERO and SPAN buttons to change into the auto / manual mode mentioned here is the setting
mode on the BLDC board. In the auto mode : Power lamp (lighting) / fault lamp (flickering)
8.7 Push the declutch gear and turn to CCW to position to the auto mode with the hex wrench after finishing
the setting.
Be sure to push the ASCN button to save the setting after limit setting.

Closing/opening limit switch
8.1 The cams ate attached to the drive stem.
8.2 Clockwise rotation = valve closing. The micro-switch closes the actuator.
8.3 Anti-clockwise rotation = valve opening. The micro-switch stops the actuator.
9. CONNEXION
The two inlet cables of the SR actuator are connected using an M20 x 1.5 connection.
9.1 The unused cable inlets must be plugged.
9.2 Standard cable glands and version for shielded cable can be used.
It is recommended to fit a glued (resin) sealing gasket on the actuator’s connections once
the wiring is completed. This is to prevent humidity and water from penetrating inside.

10. ELECTRICAL WIRING
10.1 Separate the cover from the actuator’s body. Unscrew the four bolts.
10.2 Before any electrical connection, check that the electrical diagram provided corresponds to the
rating plate.
10.3 Check that the mains voltage corresponds to the voltage mentioned on the rating plate.
10.4 The SR actuator series has a WAGO terminal box which is easy to wire and is protected against vibrations.
Use an AWG 28-4 standard cable.
10.5 Insert a screwdriver as shown above, press and insert the wire.
10.6 Check that the actuator’s earthing is compliant indoors (body) and outdoors (body).
Use a wire of identical cross-section 4.5 ~ 5 mm² for earthing the SR actuator.
10.7 Each actuator has to be actuated by their own individual relays to prevent the voltage from coming back
and possible damage to other actuators.

1 - Fail close :
When there is no input signal, the actuator auto manically turns to a full close positon.
2 - Fail open :
When there is no input signal, the actuator auto manically turns to a full open positon.
3 - AFULL :
- If the input signal is at 3.8 ~ 4.3mA , the actuator turns to a full close position.
- If the input signal is at 19.7 ~ 20.2mA , the actuator turns to a full open position.
4 - CH1 : Optional modulation
- It is used when the user voluntarily changes the input signal.
Example : When setting to 6~18mA Input.
- CH1 ON →Input 6mA and press ZERO button.
- Input 18mA and press SPAN button. →CH1 OFF.
- Input and check if the device operates normally.
5 - CH2 : Optional modulation using manual lever
- If is used when the user controls the actuator using the manual lever.
Example : When controlling using the manual lever.
- CH2 ON →Put the actuator at Full Close.
→Press the ZERO button→Put the actuator at Full Open.
→Press the SPAN button→CH2 OFF.
→Input and check if the device operates normally.
6 - REV :
- It is used when the actuator operates in the inverse direction.
- When REV is on and at 4mA, the actuator turns to a full open position, and to a full close position when at 20mA.
