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.

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 on or kick 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 withoxygen or nitrous oxide.

•••

Not to be opened by unauthorised personnel.
Do not sideload the actuator.
When mounting the actuator in the application ensure that the bolts can withstand the wear andthat they are secured safely.

••

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

•

Do not place load on the actuator housing and do prevent impact or blows, or any other form ofstress to the housing.
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 overtime 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 equippedwith an electrical safety device (current monitoring) or external limit switch.
The cable should not be used for carrying the actuator.
We recommend taking some precaution and designing the wire connection in such a way that thecable 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 theunits 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 bend and be damaged.

Figure 1

The load should act along the stroke axis of the actuator as offcentre 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 highimportance 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 trappedand 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.

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 2 Nm (1), and thereafter a maximum 90 degrees turnoutwards again (2).
030618/DS• As the piston rod eye can turn freely, it is important to ensure thatthe eye cannot rotate if theactuator is used in a pull Instruktion
application.
If
thishappens,
theactuatorwill
bepulled apart and destroyed.

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, 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® actuators are not designed for use within the following fields:• Offshore installations			
• Explosive environments• Aeroplanes and other aircraft• Nuclear power generation

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 thepower 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 Analogue feedback or Mechanical potentiometer feedback, the Signal
GND must be used. For optimal accuracy, the Signal GND is connected to the Power GND as close to the
feedback input equipment as possible.

Test of conducted and radiated emission (EMC)
All TECHLINE actuators have been tested in accordance with EN55011 class B (2007) (CISPR 11).
A 1 m 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 thiscapacitor. 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 theconnected 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 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
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 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.
