1SAFETY
This device complies with current applicable safety standards.
The installation, maintenance, and use of this unit require a skilled
and trained personnel.
Please carefully read this whole document before mounting and
powering the actuator.
2PACKAGING, STORAGE AND MAINTENANCE
2.1 Packaging
The AT actuator packaging is comprised of a corrugated, double wall
cardboard box strapped on a pallet. For certain non-EU countries or
upon request, the pallets are heat treated to the NIMP 15 standard
and IPPC-stamped.
This packaging is identical for shipping by road, air or sea, unless
otherwise mentioned in the contract.
2.1.1 Check identification sticker
The information on the nameplate sticker on the side of the actuator
should match your order.
The 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 at a stable ambient temperature.

•Avoid placing the actuator directly on the floor.
•Check that the cable entry plugs are correctly tightened.
•Check that the cover screws are correctly tightened to ensure
weatherproof sealing of the cover.
AT actuators include electrical components and lubricated gears. If
the actuator is incorrectly stored, regardless of its weatherproof
enclosure, alterations may occur, such as oxidation, galling, and
other.

The heating resistance should be connected to the power supply,
especially if the storage place is wet.

What to check before mounting on the valve, after storage
1. Visually check the electrical equipment for traces of
corrosion, humidity, etc.
2. Check that there are no oil leaks.
3. Manually operate buttons, selectors, etc., to ensure proper
mechanical functionality.
4. Manually operate the actuator in both directions for a couple
of turns.
What to check on pre-installed actuators
If you expect a long delay between actuator valve mounting and
electrical wiring, visually check that the cable entries and cover are
tightly closed.
2.3 Maintenance
All AT actuators feature lifetime lubrication. They require no
specific maintenance under the condition that they were correctly
commissioned and operated under their intended use.

English

3ACTUATOR INSTALLATION
3.1 Mounting the actuator on the valve
The 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.

If needed, the orientation of the display can be modified to keep a
normal reading orientation (see §5.4.3).
3.2 Opening the control compartment
Open the control compartment and remove the cover in order to wire
the actuator.

When opening the compartment, unplug the control panel cable
from the main board in order to avoid damaging it.
How to remove the cover
1. With a 10 mm angled
socket wrench or flat-
blade screwdriver,
unscrew the 4 screws
securing the cover to
the housing.
2. Pull out the cover
along its axis.
3. When the cover plug is
accessible, unplug it
from the main board.
4. Remove the cover completely.

However:
•Do not lift or handle the actuator by its handwheel to avoid shaft
and gear damage.
•Cable glands must not be oriented upwards (loss of
watertightness).
•It is recommended not to position the motor downwards.

3.3.2 Installing the cable glands
AT actuators are fitted with 2×M16 and 3×M20 cable entries.
How to install the cable glands
For each cable entry used
1. Remove the plug from the cable
entry with a 19 mm (M16 entry) or
23 mm (M20 entry) open-end
wrench.
2. Separate the sealing nut from its
cable gland.
3. Screw and tighten the cable gland
into the cable entry.
4. Insert the sealing nut on the cable
and pass the cable through the cable gland.
3.3.3 Wiring power and control cables
Terminal board
On a side of the electronics
assembly there are:
•a screw terminal block to
connect command and
signaling (A).
•3 push-on connectors to
connect the power supply
(B).
Control terminals: 1-36
Power connectors (3Ph/1Ph)
•3Ph: L1, L2, L3 with phase
correction
•1Ph: L (Live), N (Neutral)

Unused entries must be kept closed using plugs as they are part of
the components allowing the actuator to be rated with IP68
protection.

Internal ground terminal
The ground terminal is a tapered hole in the plate, located under
the terminal board at its left.
How to wire the actuator
The wiring must be done according to the wiring diagram of the
actuator.
1. Make sure that the power supply voltage matches the
information on the nameplate located on the side of the
actuator.
2. Separate the female part of the push-on connector from the
male part which is fixed to the board.
3. Using a crimping tool, connect the power supply to the female
push-on connectors.
4. Place back the female connectors on the male connectors
marked L1, L2 & L3 (3Ph) or L, N (1Ph), depending on the
power supply phase.
5. Using a crimping tool, attach the end of the ground cable to
the ring lug
6. Using a 4 mm hex key, secure the ground cable to the ground
terminal.
7. Using a 3×0.5 mm flat-blade screwdriver, connect the control
and signaling wires to terminals 1 to 36.
8. Tighten the sealing nut on the cable gland when the wiring is
complete.
9. Make sure that all cable glands are correctly tightened.

3.3.5 Relays
The AT Logic is equipped with a Fault relay and 3 signaling relays.
See list of Fault relay Alarms in Appendix III. This list
cannot be modified.
Customizable relays
Out of the 3 signaling relays, one is customizable. A 4-Relay board
can be added as an option (each relay is customizable).
To see possible settings and set relays, see §5.7.

3.3.6 Positioner board (OPTION)
The positioner board is
assembled on the main board.
It is possible to pick between mA
and Vusing the small switch at
the base of the board.
3.3.7 Heating resistance
Each actuator includes a heating resistance.
As soon as the actuator is installed in the field, it is required to
supply the resistance to prevent condensation.

•Immediately put the cover back in place after installation and
make sure that its seal is clean. Never leave the actuator’s
electrical components without their protection cover.
In case of water intrusion:
•Dry the electrical components before putting back the cover.
•Check the electrical insulation.

English

3.4 Closing the control compartment

Make sure to re-plug the cover wire on the mainboard, otherwise
the control panel (see §4.1) will not work.
How to close the electrical compartment
1. Plug the cover wire on the mainboard.
1. Put back the cover, making sure that the screen is correctly
oriented for operation, and place it on the housing.
2. With a 10 mm angled socket wrench or flat-blade
screwdriver, secure the cover to the housing with the
4 screws.
3.5 Wiring the external ground terminal
1. Crimp the end of the ground cable with a
6 mm ring lug.
2. Using a 5 mm Allen key, fix the ground
cable on the housing next to the cable
entries (see image opposite).
