Preface

We are delighted that you have chosen a product from LINAK. LINAK

systems are high-tech products based on many years of experience in the

manufacture and development of actuators, electronic control boxes,

controls, and chargers. We are also constantly improving our products to

meet customer requirements.

This user manual will tell you how to install, use, and maintain your LINAK

LA36 actuator.

We are sure that the LA36 actuator will give you a problemfree operation.

Before our products leave the factory they undergo full function and quality

testing. Should you nevertheless experience problems with your LINAK pro-

ducts, you are always welcome to contact our service departments or service

centres.

Most LINAK subsidiaries have authorised service centres, which are always

ready to help you.

LINAK provides a warranty on all its products. This warranty, however, is

subject to correct use in accordance with the speciﬁcations, maintenance

being done correctly and any repairs being carried out at a service centre,

which is authorised to repair LINAK products.

Safety instructions

Please read the following safety information carefully.

Ensure that all staff who are to connect, mount, or use the actuator are in

possession of the necessary information and that they have access to this user

manual.

Persons who do not have the necessary experience or knowledge of the

product/products must not use the product/ products. Besides, persons with

reduced physical or mental abilities must not use the product/products,

unless they are under surveillance or they have been thoroughly instructed

in the use of the apparatus by a person who is responsible for the safety of

these persons.

Moreover, children must be under surveillance to ensure that they do not

play with the product.

Before you start mounting/dismounting, ensure that the following points

are observed:

• The actuator is not in operation.

• The mains current supply is switched off and the plug has been pulled out.

• The actuator is free from loads that could be released during this work.

Before you put the actuator into operation, check the following:

• The actuator is correctly mounted as indicated in the relevant user instructions.

• The equipment can be freely moved over the actuator’s whole working

area.

• The actuator is connected to a mains electricity supply/transformer with

the correct voltage and which is dimensioned and adapted to the actuator

in question.

During operation

• Listen for unusual sounds and watch out for uneven running. Stop the

actuator immediately if anything unusual is observed.

When the equipment is not in use

• Switch off the mains supply or pull out the plug in order to prevent

unintentional operation.

Classification

The equipment is not suitable for use in the presence of a flammable

anaesthetic mixture with air or with oxygen or nitrous oxide.

Important information

Information about the actuators is described under the following two

headings:

Warning!

Failing to follow these instructions can cause accidents resulting in

serious personal injury.

Failing to follow these instructions can result in the actuator suffering

damage or being ruined.

Warranty

There is a 12 months’ warranty on the TECHLINE products against

manufacturing faults calculated from the production date of the individual

products (see label). LINAK’s warranty is only valid in so far as the equipment

has been used and maintained correctly and has not been tampered with.

Furthermore, the actuator must not be exposed to violent treatment. In the

event of this, the warranty will be ineffective/invalid. For further details,

please see LINAK A/S ordinary conditions of sale.

Maintenance

• The actuator must be cleaned at regular intervals to remove dust and

dirt and inspected for mechanical damages or wear.

• Inspect attachment points, wires, piston rod, cabinet, and plug, as well

as check that the actuator functions correctly.

•

The actuator is a closed unit and requires no internal maintenance.

•

To ensure that the pregreased inner tube remains lubricated the actuator

must only be washed down when the piston rod is fully retracted.

Warning!

If irregularities are observed, the actuator must be replaced.

Motor protection: Automatic protection resets thermal overload

Cable: Motor: 2 x 14 AWG PVC cable

Control: 6 x 20 AWG PVC cable

Gear ratio: 4 different gear ratios available in steel (2600 N/1700 N,

4500 N, and 10,000 N)

Slip clutch: Mechanical - overload protection through an integrated

slip clutch is optional adjusted to 1.2-1.4 times max. load

Brake: Integrated brake ensures a high self-locking ability.

The brake is deactivated when the actuator is

powered in order to obtain a high efﬁciency

Acme spindle: Trapezoidal spindle with high efﬁciency

Temperature range: - 30o C to +65o C

- 22o F to +150o F

Full performance +5o C to +40o C

End play: 2 mm maximum

Weather protection: Rated IP 66 for outdoor use. Furthermore the actuator

can be washed down with a high-pressure washer.

Mounting guidelines

LINAK®linear actuators are quickly

and easily mounted by slipping pins

through the holes on each end of

the units and into brackets on the

machine frame and the load.

The mounting pins must be parallel

to each other as shown in Figure 1.

Pins, which are not parallel to each

other, may cause the actuator to

bind and be damaged.

The load should act along the

stroke axis of the actuator since

off centre loads may cause

bending and lead to premature

failure. See Figure 2.

Make sure the mounting pins are

supported in both ends. Failure to

do so could shorten the life of the

actuator. Cantilever mounts are

unacceptable.

Warning!

If the actuator is used for pull in an application where personal injury

can occur, the following is valid:

It is the application manufacturer’s responsibility to incorporate a

suitable safety arrangement, which will prevent personal injury from

occurring, if the actuator should fail.

Warning!

LINAK’s actuators are not constructed for use within the following

fields:

• Offshore installations

• Aeroplanes and other aircraft

• Explosive environments

• Nuclear power generation
