1DOCUMENTS

Please keep this manual and all the documents that accompany it

nearby so that you can consult them if necessary.

We decline all responsibility for damages caused by not observing

the instructions of this manual.

English

2INTENDED USE OF THE ACTUATOR

Bernard Controls actuators are manufactured in accordance with the

latest technical evolutions and safety regulations.

The AQ SWITCH and AQ SWITCH POSITIONER are intended to operate

a valve or a damper in moderate environmental and operational

constraints.

All other uses are considered inadequate.

In no case will the manufacturer be held responsible for damages or

harm caused by using the actuator for any purpose other than that

for which it is designed. The user takes responsibility for all risks.

The notion of intended use also includes compliance with the

instructions in this manual and all accompanying documents, as well

as compliance with the installation and maintenance conditions.

3SAFETY

This device complies with current applicable safety standards.

The installation, use and maintenance of this unit require a skilled

and trained staff.

Please carefully read this entire document before mounting and

starting-up the actuator.



Warnings and cautions in this manual cannot cover all the risks

associated with the use of the actuator. In addition to the

instructions given, it is important to exercise good judgment and

apply basic principles of safety.



As a standard, AQ actuators are configured to close clockwise.

If your actuator closes counterclockwise, please see §6.1.

English

4PACKAGING, STORAGE AND MAINTENANCE

4.1 Packaging

AQ actuators are delivered in a cardboard box of a size equivalent to

the actuator and sit in a cardboard wedge.

4.2 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 the plugs on cable entries are correctly tightened.

•Check that the cover screws are correctly tightened to ensure

weatherproof sealing of the cover.



The heating element must be connected to the power supply,

especially if the storage place is wet (standard 230 VAC, except

otherwise specified).

AQ actuators include electrical components and lubricated gears.

Even with a weatherproof enclosure, oxidation, seizing and other

alterations may occur if actuators are not correctly stored.

What to check after storage

1. Visually check the electrical equipment.

2. Manually operate the micro-switches, buttons, selectors,

etc., to ensure their proper mechanical functioning.

3. Manually operate the actuator.

4.3 Maintenance

This actuator features lifetime lubrication. If the device is correctly

mounted and sealed, no specific maintenance is required.

Test the motor operation once a year and make sure that the

electrical compartment is free from condensation.

This actuator includes an anticondensation heater to avoid

condensation build-up when operating in a wet atmosphere.

English

5HANDWHEEL OPERATION

AQ actuators feature a handwheel for safety operation.

To avoid potentially harmful rotating protruding parts during

electrical operation, AQ handwheels feature a foldable handle: you

can fold it during electrical operation and unfold it if you need to

operate the actuator manually.

6ASSEMBLY ON THE VALVE OR DAMPER

The actuator should be directly attached to the valve using proper

bolts or via a proper interface.

If the valve is in the closed position, then the actuator should also

be installed in the closed position. If the valve is open, so should be

the actuator.



If you cannot reach the correct position because you are blocked by

a mechanical stop, loosen the mechanical stop so that you have

enough space to go to the correct position.

After assembly on the valve or on the damper, the actuator can

operate in any position.



However:

•do not lift the actuator by the handwheel to avoid damage on

internal gearing.

•cable glands must not be oriented upwards (loss of water

tightness).

6.1 Changing closing direction visual indication

As a standard, AQ actuators are configured to close clockwise. If the

actuator must close counterclockwise, you can change the

orientation of the position indicator cap.

English

Standard indicator orientation

for clockwise closing

Reverse indicator orientation

for counterclockwise 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.

English
