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 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 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.

• 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 7 of 36

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 oxygen
or nitrous oxide.

Warnings

• Do not sideload the actuator.

• When mounting the actuator 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.

• For actuators with a stroke length below 130mm, the extended position of the mechanical endstop will
always be at 130mm. That means, if an actuator has a stroke of 80mm and the endstop switch in outwards
direction fails, the actuator will travel additional 50mm before reaching mechanical endstop.

Recommendations

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

• Ensure that the cable cover is mounted correctly. Use 1.5Nm torque.

• Ensure that the duty cycle and the usage temperatures for LA12 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 to
water 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 an electrical
safety device (current monitoring) or external limit switch.

• The cable 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.

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.

Figure 2

Right WrongWrong

Wrong

Figure 1

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 bend and be damaged.

The load should act along the stroke axis of the actuator
as 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. Also,
avoid applying a skew load on the actuator.

The actuator can rotate around the pivot point in the front and rear end. If this is the case it is of high importance
that 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.

Page 9 of 36

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 he 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 turn
outwards again (2).

• As the piston rod eye can turn freely, it is important to ensure that the eye cannot rotate if the
actuator is used in a pull application. If this happens, the actuator will be pulled apart and destroyed.

Til salesbackup, brugsanvisning og datablad.

Ved montage og ibrugtagning, er det ikke tilladt at dreje unødvendigt mange gange på
stempelstangsrøret. Hvis øjet ikke er positioneret korrekt, er det tilladt først at skrue
røret i bund (1), og derefter skrue det maksimalt ½ omgang ud igen (2).

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 designed for use within the following fields:

• Offshore installations • Explosive environments

• Aeroplanes and other aircraft • Nuclear power generation

Page 10 of 36

Electrical installation

Recommended fuse for actuators without integrated controller

• 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 the output,
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.

Correct wiring of Power GND and Signal GND for IC

When using the feedback output, it is important to use the right connection setup. Attention should be paid to
the two ground connections. Power GND in the Power connector and Signal GND in the Control connector. When
using either 0-10V, Hall or PWM feedback, the Signal GND must be used. For optimal accuracy, the Signal GND is
connected to the Power GND as close as possible to the feedback input equipment.

Test of conducted and radiated emission (EMC)

All TECHLINE actuators have been tested in accordance with EN55011 class B (2007) (CISPR 11).
A 1m cable has been used in the test set-up.

Actuator without H-bridge

1) For normal operation the following is valid:

• Radiated emission requirements are met.

• Conducted emission requirements are met. However, to meet with these requirements a capacitor has been

mounted across the motor wires outside the actuator, and tests have then been made with this capacitor.
Capacitor values for some of the TECHLINE actuators can be found in the scheme below.

To comply with EN55011 class B (2007) a capacitor must be added across the motor wires, or the
connected control box must have similar/better filtering. The actuator is not delivered with a built in
capacitor, because then it would not be possible to PWM the motor for those who would want to do
that.

Please view the scheme below for the correct choice of capacitor for the actuator in question.

2) For systems/operations that use PWM-control it is up to the customer to test and meet the requirements.

Actuator with H-bridge

1) For normal operation with soft start/stop the following is valid:

• The actuator has been tested when operating with constant 80%-PWM.

• Radiated emission requirements are met.

• Conducted emission requirements are met.

2) For systems with LINAK PWM regulation (among other things parallel operation and speed regulation)
the following is valid:

• Radiated emission requirements are met.

• Conducted emission requirements are met.

3) Speed regulation:

• If the speed is regulated below a nominal speed of 80% (80%-PWM), it is necessary to mount a filter in order
to comply with the conducted emission requirements. For systems/operations that are speed regulated, it is up
to the customer to test and meet the requirements.

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.

• To ensure that the pregreased inner tube remains lubricated, the actuator

must only be washed down when the

piston 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 actuators
from LINAK are greased with anticorrosive grease or similar.
