Chapter 1
Safety instructions
Please read this safety information carefully:
Be aware of the following three symbols throughout the user manual:Warning!
Failing to follow these instructions can cause accidents resulting in serious personal injury.
Recommendations
Failing to follow these instructions can result in the actuator suffering damage or being ruined.
Additional information
Usage tips or additional information that is important in connection with the use of the actuator.

Furthermore, ensure that all staff who are to connect, mount, or use the actuator are in possession of thenecessary 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 theproduct/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 aperson 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 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 isdimensioned and adapted to the actuator in question.

•

Ensure that the voltage applied matches to the voltage specified on the actuator label.

•

Ensure that the connection bolts can withstand the wear.

•

Ensure that the connection bolts are secured safely.

Page 6 of 40

During operation, please be aware of the following:•

Listen for unusual sounds and watch out for uneven running. Stop the actuator immediately if anything
unusual is observed.

•

Do not sideload the actuator.

•

Only use the actuator within the specified working limits.

•

Do not step or kick on the actuator.

When the equipment is not in use:•

Switch off the mains supply in order to prevent unintentional operation.

•

Check regularly for extraordinary wear.

Classification
The equipment is not suitable for use in the presence of a flammable anaesthetic mixture with air or with oxygenor nitrous oxide.

Warnings•

Do not sideload the actuator.

•

When mounting the LA35 in the application ensure that the bolts can withstand the wear and that they
are secured safely.

•

If irregularities are observed, the actuator must be replaced.

Recommendations•

Do not place load on the actuator housing and do prevent impact or blows, or any other form of stress tothe housing.

•

Ensure that the cable cover is mounted correctly. Use 3.5Nm torque.

•

Ensure that the duty cycle and the usage temperatures for LA35 actuators are respected.

•

Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.

•

Furthermore, it will be good practice to ensure that the actuator is fully retracted in the “normal” position.
The reason is that there will be a vacuum inside the actuator if it is extended which over time can lead towater entering the actuator.

•

If the actuator (without integrated controller) is mounted in an application where a mechanical stop
prevents the endstop switches in the actuator from being activated, the actuator must be equipped with anelectrical safety device (current monitoring) or external limit switch.

Chapter 2
Mounting guidelines
LINAK® linear actuators are quickly and easily mounted by slipping pins through the holes on each end of theunits and into brackets on the machine frame and the load.
The mounting pins must be parallel to each other asshown in Figure 1. Pins, which are not parallel to eachother, may cause the actuator to bend and be damaged.

Figure 1X

The load should act along the stroke axis of the actuator
as off-centre loads may cause bending and lead topremature 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.
Also, avoid applying a skew load on the actuator.

X

The actuator can rotate around the pivot point in the front and rear end. If this is the case it is of high importancethat the actuator is able to move freely over the full stroke length, both during the development and daily
operation. Please pay special attention to the area around the housing where parts can be trapped and cause
damage to the application and actuator.
In applications with high dynamic forces LINAK recommends not to use the fully extended or retracted position
over longer time, as this can damage the endstop system permanently.

Figure 2

Please be aware that if the LA35 is used for solar applications the actuator must be mounted with the
motor housing turned upwards and the wires pointing downwards.
Page 8 of 40

Mounting guidelines• The mounting pins must have the correct dimension.
• The bolts and nuts must be made of a high quality steel grade (e.g. 10.8).
No thread on the bolt inside the back fixture or the piston rod eye.
• Bolts and nuts must be protected so there is no risk for them to fall out.
• Do not use a torque that is too high when mounting the bolts for the back fixture or the piston rod
eye. This will stress the fixtures.
Please note:
The piston rod eye is only allowed to turn 0-90 degrees.
Instruction concerning the turning of the piston rod eye and inner tube:•
When mounting and taking into use, it is not permitted to make excessive turns of the piston rod
eye. In cases where the eye is not positioned correctly, it is permitted to first screw the eye down
to its bottom position, at a maximum torque of 2Nm (1), and thereafter a maximum 90 degrees
030618/DS
turn outwards again (2).
•Instruktion vedr. uddrejning af inderrør – LA27 + LA27C
As the piston rod eye
can turn freely, it is important to ensure that the eye cannot rotate if

Warning!
If the actuator is used for pull in an application where personal injury can occur, thefollowing 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 designed for use within the following fields:• Offshore installations		
• Explosive environments• Aeroplanes and other aircraft		• Nuclear power generation

Mounting of cables

1. Unscrew the cover and remove the two
cables and/or blind plugs.

2. Plug in the power cable and/or
the signal cable.

3. Slide the cover onto
the actuator.
The torque of thecover screw isapprox. 3.5 ± 0.2 Nm
TORX 25IP

When changing the cables on a LINAK actuator, it is important that this is done carefully, in order toprotect the plugs and pins. Before the new cable is mounted, we recommend that the socket is greased
with vaseline, to keep the high IP protection and ensure an easy mounting. Please be sure that the plugis in the right location and fully pressed in before the cable lid is mounted.
Please note that if the cables are mounted and dismounted more than 3 times the plugs can be damaged.
Therefore, we recommend that such cables are discarded and replaced.
Also note that the cables should not be used for carrying the actuator.
We recommend to take some precaution and design the wire connection in a way, where the cable end
is kept inside a closed, protected area to guarantee the high IP protection.
Page 10 of 40

Electrical installation•

To ensure maximum self-locking ability, please be sure that the motor is shorted when stopped.
Actuators with integrated controller provide this feature, as long as the actuator is powered.

•

When using soft stop on a DC-motor, a short peak of higher voltage will be sent back towards
the power supply. It is important when selecting the power supply that it does not turn off theoutput, when this backwards load dump occurs.

The power supply for actuators without integrated controller must be monitored externally and cut off
in case of current overload.

Chapter 5
Maintenance•

The actuator must be cleaned at regular intervals to remove dust and dirt and inspected for mechanicaldamages or wear.

•

Inspect attachment points, wires, piston rod, cabinet, and plug, as well as check that the actuator functions
correctly.

•

To ensure that the pregreased inner tube remains lubricated, the actuator must only be washed down when thepiston rod is fully retracted.

•

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

•

In order to maintain a proper performance of the spherical eyes and to increase the resistance against
environmental wear, we strongly recommend that the spherical eyes (ball bearings) mounted on actuatorsfrom LINAK are greased with anticorrosive grease or similar.

RepairOnly an authorised LINAK® service centre should repair LINAK actuator systems. Systems to be repaired underwarranty must be sent to an authorised LINAK service centre.
In order to avoid the risk of malfunction, all actuator repairs must only be carried out by an authorised LINAKService shop or repairer, as special tools and parts must be used.
If a system is opened by unauthorised personel there is a risk that it may malfunction at a later date.
