1SAFETY
This device complies with current applicable safety standards.
Installation, maintenance,and use of this unit require a skilled and
trained staff.
Please carefully read this whole document before mounting and
starting-up the actuator.
2DELIVERY,STORAGE AND MAINTENANCE
2.1 Delivery
AQ actuatorsare delivered in a cardboard box of a size equivalent to
the actuator and sit in a cardboard wedge.
2.1.1 Check identification sticker
Information on the nameplate sticker on the side of the actuator
should match those on your order.
QR Code on this sticker can be used to identify the actuator.
2.2 Storage
Actuators should be stored under a shelter, in a clean and dry place
and protected from wide temperature variations.

•Avoid placing the actuator directly on the floor
•Check that plugs of cable entries are correctly tightened
•Check that cover screws are correctly tightened to ensure
weatherproof sealing of the cover
AQ actuator includes electrical components and lubricated gear
stages. Even with a weatherproof enclosure, oxidation, seizing and
other alterations may occur if actuator is not correctly stored.
What to check after storage
1. Visually check the electrical equipment.
2. Manually operate buttons, selectors, etc., to ensure their
proper mechanical functionality.
3. Manually operate the actuator.

What to check on pre-installed actuators
If you expect a long period between actuator mounting and electrical
wiring:
4. Visually check that cable entries and cover are tightly closed.
5. In case of outdoor installation, cover the unit with a plastic
protective film.
Actuators equipped with electronic components
Long term storage of electronic components which are not in service
increases the malfunction risk. This is not advisable.
If a long term storage is absolutely necessary, we strongly
recommend a revision of the electronic boards in our factory before
actuator usage.
2.3 Maintenance
This actuator features lifetime lubrication. While the device is
correctly mounted and sealed, no specific maintenance is required.
Test motor operation once a year and make sure that electrical
compartment is free from condensation.
If it operates in a wet atmosphere, this actuator includes an anti-
condensation heater to avoid condensation build-up.

3ACTUATOR INSTALLATION
3.1 Fastening actuator on the valve
Actuator should be secured directly to the
valve using proper bolts or via a proper
interface.
After assembly, the actuator can operate in
any position.

You can modify your display orientation in order to keep normal
reading orientation.
To set your display orientation, see §0.

However:
•do not handle the actuator by handwheel to avoid damage on
actuator gearing
•cable glands must
not be oriented upwards (loss of water
tightness)
3.2 Opening the control compartment
You need to open the control compartment and remove the cover in
order to wire actuator. If closing direction is not standard (clockwise),
and it is not already done, change the orientation of the position
indicator cap.
How to remove the cover
1. With 10mm angled socket
wrench or flat blade
screwdriver, untighten the 4
screws.
2. Raise the cover then unplug it
from the board.

3.2.1 Changing closing direction indication
As a standard, AQ actuator is configured to close clockwise. If the
actuator must close counter-clockwise, you can change the
orientation of the position indicator cap.

This change requires to have the actuator software set
accordingly.

To proceed to this setting, see §5.2.
Standard indicator orientation
for clockwise closing
Reverse indicator orientation
for counter-clockwise closing
How to change cap orientation
1. Disassemble the cover then the
cap.
2. Turn the cap 90°.
3. Reassemble the cap then the
cover.

3.3.2 Connection and preliminary tests
First install cable glands, then connect wires on the terminal blocks.
!Ensure wires are not supplied with electric power before wiring is
finished and the control compartment is closed.
If you need to open control compartment, previously cut off power
supply to the actuator.

How to install cable glands
For each cable entry used
1. Remove plug from the cable entrywith 19mm (M16 entry)
or 23mm (M20 entry) open-
end wrench.
2. Separate sealing nut from
its cable gland.
3. Screw and tighten cable
gland in the cable entry.
4. Thread the sealing nut on
the cable and pass the
cable through the cable
gland.
Terminal blocks
Terminal blocks are located on a
side of the electronic assembly
and
consists of screwed
terminals. There are 2 main
blocks: 1st is to connect power
supply, 2nd to connect command
and signaling.
Control terminals are 1-35 & 2-36
Power terminals (3Ph/1Ph)
•3Ph: L1, L2, L3 with phase
correction
•1Ph: L (Live), N (Neutral)
Both thermal protector and torque limit device must be integrated
into your control system in order to prevent potential damage to the
actuator or valve.

Unused entries must be kept closed by their plug.

Internal ground terminal
The ground terminal is a metal tab with a fixation hole located under
the terminal board at its bottom left (see following picture).
How to wire actuator
The wiring must be done according to the wiring diagram of your
actuator.
Using a 3×0.5mm flat blade
screwdriver and a 4 mm Allen
key
1. Connect power supply on
terminals marked L1, L2 &
L3 (3Ph) or L, N (1Ph)
according to your supply
type.
2. At the same time, connect
ground cable on ground
terminal.
3. Connect control and signaling wires on uneven (marked 1
to 35) and even (marked 2 to 36) upper terminals.
4. Tighten sealing nut on the cable gland when you have
finished wiring.

3.3.3 Power supply board
Power supply board supplies
actuator with electrical
power.
Power characteristics are
factory set according to your
order.
Fuse
You have a fuse at the upper
left angle of the board (see
picture).
Its characteristics are the following:
Fuse current 500 mA Fuse size (mm)
(inches)
6.3×32
¼’’×1-¼’’
Voltage rating VAC 500 V Blow characteristic Fast acting
Breaking current capacity current AC 1 kA
3.3.4 Relays
AQ Logic actuator is equipped with 3 relays, to which you can
optionally add a 4-Relays board.
Function of each relay can be set.
To see possible settings and set relays, see §5.8.

3.3.5 Positioner board (OPTION)
Positioner board is assembled
on the main board.
You can switch between mA
and Vusing the small switch at
the base of the board according
to your needs.
3.3.6 Heating resistor
Each actuator includes a heating resistor.
As soon as the actuator is installed in the field, it is recommended
to supply the resistor to prevent condensation.

•Immediately put the cover back in place after start-up while
ensuring its sea
l is clean. Never leave actuator electrical
components without their protection cover.
In case of water intrusion:
•dry electrical components before putting back the cover.
•check electrical insulation.
3.4 Closing the control compartment
To close the control compartment, see §3.2 and follow the
steps in the opposite order.

Make sure to re-plug the cover on the mainboard, otherwise control
panel (see §4.1)will not work.

4.5 Remote control
The AQ Logic remote control system can be operated using an
external or an internal voltage supply.
The input circuits are fully opto-isolated. The self-hold pulse
command system requires 4 connecting wires on the client terminal
strip: Common, STOP, OPEN and CLOSE. If the STOP push-button is
not used, do not connect the STOP wire, OPEN (or CLOSE) contact
must be maintained to operate the actuator.

These commands are self-holding (pulse commands) as a standard.
To remove self-holding, remove wire to terminal 7.
4.5.1 Dry contact control
A jumper must be fitted across customer terminal 9-10.
S - Stop
C - Close
O- Open
4.5.2 Voltage control
Remote control can use either in AC or DC voltage.
S- Stop
C - Close
O- Open
Use terminal 10 for voltage from 10 to 60V.
Use terminal 11 for voltage from 90 to 250V.
!
Never connect voltage sources above 60V on common terminal 5.

5COMMISSIONNING
This section describes the commissioning with the Control
panel, except otherwise mentioned.
You can set the same settings with App from the menu
Settings > Commissioning of Actuator on valve.
In order to access the actuator settings, control mode must
be set to Local mode.
5.1 Accessing the actuator menu
To be able to set the actuator software or check the warnings or
alarms, you need to access the actuator menu, either with Control
panel or BC App depending on which Local control you use.

It is your responsability to set the security of the Local
Commands (Control Panel or Smartphone Application) for
your process:
•The default position of the Control selector button
should be on Remote
•The Access Code of the actuator should have been
changed
•The remote command "Local Command Inhibition" (from
DCS) should be active
