Important information
LINAK® products, within the scope of this manual, are not classified as medical electrical equipment or systems, nor do they fall within the scope of
the EU Medical Device Directive/Regulation or other similar national regulations. The products are components to be built into a piece of medical
electrical equipment by a manufacturer.
To support the assessment and certification task of the complete medical electrical equipment or system worldwide, LINAK provides certification,
on a component level, according to the IEC 60601-1, (Medical electrical equipment – Part 1: General requirements for basic safety and essential
performance) as IEC-certificate and listed as recognised components by NRTL (Nationally Recognized Testing Laboratories).
Description of the various signs used in this manual:
Warning
Failure to comply with these instructions may result in accidents involving serious personal injury.
Recommendation
Failing to follow these instructions can result in product damage.
Please read the following safety information carefully:
It is important for everyone who is to connect, install or use the systems to have the necessary information and access to this User Manual.
Please be aware that LINAK has taken precautions to ensure the safety of the actuator system. The manufacturer/OEM is responsible for the overall
approval of the complete application.
LINAK recommends to use the actuators in push applications rather than pull applications.
LINAK actuators are not to be used for repeated dynamic push-to-pull movements.
For general pull applications or repeated dynamic push-to-pull movements in the application, please contact LINAK A/S if in doubt.
®
actuators and electronics generally fall outside the IEC 60601-1 definition of applied parts and are not marked as such.
LINAK
However, assessing the risk whether actuators and electronics can unintentionally come into contact with the patient, determines that they are
subject to the requirements for applied parts. All the relevant requirements and tests of the standard are carried out as part of the IEC CB-Scheme
assessment.
RF transmitter properties:
Some LINAK products emit RF-power by intention for communication purposes.
Frequency band of transmission: 2400 MHz – 2485 MHz.
Type: BLUETOOTH Low Energy BLE 4.2
Modulation: GFSK
Maximum Effective Radiated Power (ERP): 10 dBm
Output ratings:
Nominal values:
On LINAK control boxes, battery boxes and power supply marking plates, the nominal output voltage at a certain load for a certain product may be
stated.
Depending on product and load, this value may vary significantly due to construction.
The expected output voltage may for instance vary depending on product and load within a range from approximately 20 V DC to approximately 50 V
DC for a product with a nominal output voltage of 24 V DC due to the construction.
When combining LINAK control boxes, battery boxes and power supplies with other LINAK components, compatibility is ensured. When combining
LINAK control boxes, battery boxes or power supplies with third party products, special precautions may be taken. In this case, contact LINAK.
Classification:

Page 7 of 192
Page 8
Warning
Electromagnetic compatibility - general
LINAK® actuator systems bear the CE marking as an attestation of compliance with the EMC Directive 2014/30/EU. The systems are
designed to meet all requirements of applicable standards and have been tested to meet IEC 60601-1-2 requirements.
Emission:
LINAK Actuator Systems are CISPR 11, Group 1, Class B products, comply with IEC 61000-3-2, Class A and IEC 61000-3-3 unless stated
otherwise in the relevant section of this document.
Immunity:
Test levels are according to Professional Healthcare Facility and Home Healthcare Facility Environment.
Electromagnetic phenomena are evaluated on a system level, with the actuator connected to a LINAK control box and accessories.
LINAK always recommends to perform verification tests on the final medical device.
Warning
Electromagnetic compatibility – third party components
Use of accessories, transducers and cables other than those specified by LINAK could result in increased electromagnetic emissions or
decreased electromagnetic immunity of the actuator system and result in improper operation.
Warning
Electromagnetic compatibility – interference with other equipment in general
Use of the actuator system adjacent to or stacked with other equipment should be avoided as this could result in improper operation. If such
use is necessary, the actuator system and the other equipment should be observed to verify that they are operating properly.
If the user notes unusual behavior of the actuator system, in particular if such behaviour is intermittent and associated with the standing
right next to mobile phones, microwaves and radio broadcast masts, this could be an indication of electromagnetic interference.
If such behaviour occurs, try to move the actuator system further away from the interfering equipment.
Warning
Electromagnetic compatibility – interference with other equipment, RF communications
Portable RF communication equipment (including peripherals such as antenna cables and external antennas) should be used at a distance
no closer than 30 cm (12 inches) to any part of the actuator system. This also applies to cables specified by the manufacturer. Otherwise, a
performance degradation of this equipment could result.
Warning
If the actuator or lifting column is used for pull in an application where personal injury can occur, the following is valid:
The medical device manufacturer is responsible for the incorporation of a suitable safety arrangement, which will prevent personal injury
from occurring in case of actuator failure.
Warning
Note that during construction of applications, in which the actuator is to be fitted, there must be no possibility of personal injury, for
example the squeezing of fingers or arms.
Warning
The plastic parts in the system cannot tolerate cutting oil.
Warning
Assure free space for movement of the application in both directions to avoid a blockade.
Warning
The application and actuators are only to be operated by instructed personnel.
Warning
In applications with spline function, the blockage by an obstacle when the application is moving inwards, the removal of the obstacle will
cause the load to drop until the spindle hits the nut.
Warning
Do not turn the outer tube.
Warning
Do not use chemicals.
Warning
Inspect the actuator system regularly for damage and wear.
Warning
Do not expose LINAK actuator system components to high intensity ultraviolet radiation disinfection lamps. This may damage the enclosure,
supporting parts and cables.
Page 8 of 192
Page 9
Warnings
LINAK® actuators and electronics are not designed for use within the following fields:
• Planes and other aircrafts
• Explosive environments
• Nuclear power generation
Warning
If faults are observed, the products must be replaced.
Warning
A LINAK control box, actuator and accessory component must, in the final application, be placed where it is not exposed to any impact. This
is to prevent damage if a passer-by accidentally hits it with an object or when cleaning the floor with a broom or a mop. On a medical bed
e.g. this might be underneath the mattress support platform. If necessary to mitigate this risk, additional protection might be required.
Warning
Handle batteries carefully. Do not short circuit the battery.
Warning
Avoid continuous battery discharge when the medical device is not in use, as this may cause lead sulphate formation, which, if left in this
state for too long, will irreversibly damage the battery.
Warning
To avoid unintended movement, prevent foreign objects or persons from unintentionally activating a footswitch or a hand control at any
time, for instance during normal use or maintenance.
Warning
LINAK battery packs may emit flammable gases. Do not expose the battery packs to fire or equipment that emits sparks. Moreover, do
not store the battery in a closed environment or incorporate it into a closed structure of an enclosure as this may cause an explosion, fire,
equipment damage, or injury.
Warning
Handle tools carefully and do not wear jewelery when handling batteries. A short-circuit of the battery terminals can cause burn injuries,
damage or trigger explosions.
Warning
Only connect LINAK batteries to compatible chargers.
Warning
LINAK battery packs contain toxic substances. If the internal battery fluid leaks out and gets onto skin or clothing, make sure it is washed off
with clean water. Moreover, if the fluid gets into the eyes, rinse them immediately with clean water and seek medical assistance.
Warning
Do not use or store LINAK battery packs in places where the ambient temperature exceeds 50 °C, such as inside a hot automobile, in direct
sunlight, or in front of a stove or a source of intense heat. Doing so can shorten the battery life, lower its performance level, cause the
battery to leak fluid, explode, cause fire, or be damaged.

Recommendation
The duty cycle printed on the actuator system label must always be respected. If exceeded, there is a risk that the actuator system is
damaged. Unless otherwise specified on the label, the duty cycle is max. 10%, max. 2 min. in use followed by 18 min. not in use.
Recommendation
Important information regarding lithium ion batteries
Li-Ion batteries are moving in the direction of minimising the physical size and at the same time increasing the capacity. This gives a very size-effective
battery but with a high concentration of energy within a small physical size. It also increases the risk of thermal runaway (see note below) due to
internal short circuits.
The general use of Li-ion batteries has increased and the inherent risk of thermal runaway has led to stricter rules within the transport industry,
specifically air transport, with tightened restrictions placed on the quantity to be transported and handled, and on the storage of specific products
moving via air.
The OEMs and end users must recognise that although safe to use, there is still a very small risk of thermal runaway in a Li-Ion cell. The size of that
risk could be as little as 1PPM or even less.
®
currently bases our Li-Ion battery design on industry proven cell types that have a proven history (e.g. electric cars). The use of well-proven
LINAK
cell technology reduces the risk of thermal runaway, but it does not eliminate it. LINAK has completed activities to reduce this risk and the complete
battery package is UL approved.
An external, internationally recognised expert has also reviewed the design to ensure that it is in accordance with the recommendations. Further to
that, LINAK only uses cells from well-recognised manufacturers.
When using Li-Ion batteries, LINAK recommends that the customer carries out a proper risk analysis for their application. The risk analysis must also
focus on non-mounted products that can be in direct contact with flammable materials.
LINAK Li-Ion batteries have no more risk of thermal runaway compared to other Li-Ion cells from well-recognised manufacturers within the market.
Therefore, it is clear that LINAK cannot take responsibility for any failures that occur due to Li-Ion battery inherent failures.
If any of the Li-Ion batteries built into LINAK products is found to be defective under warranty, LINAK will provide a new product to the OEM. LINAK
explicitly disclaims all other remedies. LINAK shall not in any event be liable under any circumstances for any special indirect punitive incidental or
consequential damages or losses arising from any incident related to the inherent risk of thermal runaway in the Li-Ion cell and any use of LINAK
products. Moreover, LINAK explicitly disclaims lost profits, failure to realise expected savings, any claim against our customers by a third party, or any
other commercial or economic losses of any kind, even if LINAK has been advised of the possibility of such damages or losses.
Note: ‘Thermal runaway’ is overheating of a cell and it could lead to a small fire and smoke from the cell.
Transportation
The lithium ion batteries must be packed and transported in accordance with applicable regulations. Always ask your local transportation provider
how to handle the transportation of lithium ion batteries.
Please see the general assembly instructions and the mounting section for detailed information.
Page 10 of 192
Page 11

• Adjustment of beds
• Patient hoists within the care and hospital sector
• Adjustment of dentist chairs/gynaecological chairs
• Etc.
The principles of a LINAK system are as follows:
LINAK
LINAK hand control
control box
Attention should be paid to the following:
• All detachable connections between components must be locked by the cable locking mechanism - when applicable.
• All cables must be mounted in such a way that they are not trapped or exposed to tension or sharp objects when the application is
moved in different directions.
LINAK actuators or lifting columns
Recommendation
It is recommended to have options like quick release, manual lowering or similar built into the system in case of power loss or system failure
or if movement of the system is critical. After service it is recommended to test the system for correct functionality before it is put back into
operation.

Electrostatic discharge (ESD)
LINAK® considers ESD to be an important issue and years of experience have shown that equipment designed to meet the levels specified in standards
might be insufficient to protect electronic equipment in certain enviroments.
1. Handling and mounting electrostatic discharge sensitive devices (ESDS devices).
• Handling of sensitive components shall only take place in an ESD Protected Area (EPA) under protected and controlled conditions.
• Wrist straps and/or conductive footwear (personal grounding) shall always be used when handling ESDS devices.
• Sensitive devices shall be protected outside the EPA by the use of ESD protective packaging.
2. Responsibility LINAK/customer.
• ESDS devices must under no circumstances, during transport, storage, handling, production or mounting in an application, be exposed to harmfull ESD.
• LINAK can only guarantee the lifetime of ESDS devices if they are handled in the same way from production at LINAK A/S until they are mounted
in the manufacturer’s application. It is therefore important that the ESDS devices are not removed from the ESD protected packaging before they
are physically within the EPA area at the customer premises.

Batteries
Lithium ion batteries
Warnings
• When using BAJL and JUMBO control boxes, loss of power might happen due to the battery deep discharge protection. This will only happen in
case of continuous battery use despite warnings. In this event, there may be no warning, and the application may not be able to move when
expected.
• In his risk analysis, the customer must take into consideration how to assure alternative means to make movement, for instance quick release or
manual lowering.
• The combination of CBJ1 or CBJ2 with BAJL might not be able to complete a full cycle after low battery warning.
• Do not open the battery housing as damaging the cell or circuitry may develop excessive heat.
• If product caution is not clearly visible at low light intensity, read the product label instructions symbol. A warning must be included in the
application manufacturer manual for the medical device.
• The application manufacturer must test the application and ensure that intentional and unintended operations do not exceed the battery
specification limits.
• Defective or damaged Li-Ion batteries are not allowed for transportation.
• For safety reasons, please adhere to the indicated charging and operation temperature.
• In case the battery is too hot, disconnect it, evacuate the room, and wait for 2 hours before taking further steps.
• Mounting instructions must be followed in order to avoid exposing batteries to water.
• Recharging of battery must take place every 6 months.
• Disposal of the battery takes place in accordance with local regulations.
Recommendations:
• Do not exceed the storage temperature as it will shorten the product life and performance.
• Allow the battery to settle to room temperature before use.
• Lithium ion batteries are not intended for use in outdoor applications and indoor pool environments.
• If the battery is completely discharged, then recharge the battery before storage.
• Always use correct LINAK
®
charger.
DO NOT:
• Heat or burn the batteries.
• Short circuit the batteries.
• Expose the batteries to high impact/excessive force.
• Crush or puncture the batteries.
• Use batteries with signs of damage or corrosion.
• Charge or store the batteries near combustible material.
• Expose the batteries to water or other liquids.
• Overcharge or fully discharge the batteries.
For detailed information on specific use of batteries, please see the product information in chapter 5.
Safety feature
Lithium ion batteries contain several mechanisms to protect themselves from being damaged due to excessive use.

Lead acid batteries
Maintenance of batteries
Prior to first use of LINAK
®
batteries, please make sure that they are charged at least 24 hours and if possible even longer for proper functioning and
prolonging the battery lifetime.
Warnings
• Please observe the following maintenance, replacement, and disposal requirements to ensure a safe and reliable operation.
• The batteries are to be replaced after 4 years at the latest. Perhaps earlier, depending on the pattern of use. Frequent and high-powered discharges
reduce the battery life. For an optimum lifetime, the product must be connected to the mains voltage as often as possible. It is recommended that the
batteries are to be charged for at least every 6 months - otherwise the batteries will have reduced capacity due to self-discharge. It is recommended to
test the battery function at least once every year.
Replacement of batteries
The batteries must only be replaced by the same type of batteries or mechanical and electrical equivalent types. The batteries must be new or
maintained by means of charging at least every 6 months. The batteries, which make a set, must be supplied with identical production codes.
Production code mismatch may lead to a severely reduced lifetime expectancy.
Before mounting, ensure that the battery set is correctly connected, compare with the drawing in the battery room and check that no connectors are
loose.
Warnings
• The battery compartment is hermetically separated from the electronics compartment. When replacing the batteries this separation must not be
damaged or modified as this may allow penetration of battery gas into the electronics compartment with risk of explosion.
• When replacing batteries in waterproof products (IPX5 and IPX6), precautions must be taken that the sealing material (silicone ring or joint filler)
is not damaged and that it is correctly placed in the groove. Hereafter, the screws in the cover are to be fastened with approx. 1 Nm. If the seal is
damaged, it must be replaced by a new silicone string (LINAK article no. 0008004 for a roll of 100 meters).
Disposal
Lead acid batteries, can be returned to LINAK or disposed of in the same way as car batteries.
Warnings
• The battery compartment is supplied with ventilation that ensures correct and necessary airing of the battery compartment. This airing must not be
blocked or covered as a positive pressure may occur with risk of explosion.
• If the product has been exposed to mechanical overload (lost on the floor, collision/squeezing in the application or a powerful stroke), the product
must be sent to an authorised workshop for control of the hermetic separation between the battery and electronics compartment.

Warnings
• Do not sideload the actuator
• Only use the actuator within specified working limits
• When mounting the LA20 in the application ensure that the bolts can withstand the wear and they are secured safely
• Motor type G and B must only be used with their respective control box types. For further specification se Chapter 3 – Compatibility.
• Motor type B: 24V motor which must be used with COBO, CBJC, CBJ1, CBJ2, CBJH or generally in applications which are mainly battery driven
• Motor type G: 24V. Running mainly on LINAK CB platforms as CO61, CO71, CO41, CA30/40, CB6 OBMe SMPS, CB16 OBF SMPS, CB20
• Instruction concerning the turning of the piston rod eye: 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 half turn outwards again (2).
Recommendations
• Do not place load on the actuator housing and do prevent impact or blows or any other form of stress to the housing
• Connection bolts must be dimensioned so that they have the necessary strength and tolerance in order to obtain the minimum safety factor according
to the requirements of the authorities
• Ensure that the cable lock is mounted correctly
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress
• Only use the actuator within the specifications
• Connection bolts and brackets are to be inspected in connection with service and must be replaced if there are signs of wear
• The product must always have the motor short circuited to obtain self-locking according to label value/rated value
• Ensure that the duty cycles and the usage temperatures for LA20 actuators are respected
• The LA20 is not suitable for use in outdoor applications where it can be exposed to sun and rain. If outdoor use cannot be avoided, it is very important
that the LA20 is mounted in a position where it is well shielded. It is up to the customer to provide the shielding. 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.
• Do not expose the actuator to pull during transport of the application

Warnings
• Do not sideload the actuator.
• Only use the actuator within specified working limits.
• When mounting the LA23 in the application ensure that the bolts can withstand the wear and that they are secured safely.
• If an actuator with stroke length below 50 mm is used, and the electrical end-stop switch fails, please be aware that the distance before reaching
the mechanical end- stop will be prolonged. The extra distance will be 50 mm minus actual stroke length.
I.e. If an actuator with 20 mm stroke length is used and the switch fails, it will travel an additional 30 mm before reaching the mechanical end-stop.
• Instruction concerning the turning of the piston rod eye
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

vacuum inside the actuator if it is extended which over time can lead to water entering the actuator.
• The B and G 24V motors must only be used with their respective control box types.
• Not acceptable: B motor with OpenBus™ control boxes!
Reason: The actuator will be too strong, it will run too fast, be noisy and only have a short lifetime. The actuator will not live up to what we promise.
• Not acceptable: G motor with 24V supply!
Reason: The actuator will be too weak, this means it will only run slowly, not be able to lift as much in the cold and under low current conditions.
The actuator will not live up to what we promise.
• If a cable lock has been removed it is recommended to check if it is has been damaged during removal. If so it is recommended to replace with a new one.
• Before mounting a cable, ensure that the cable, cable plug or o-ring is not damaged. If damage is observed, the cable must be replaced with a new one.

6. LA27 (MEDLINE® CARELINE® HOMELINE®)
The LA27 actuator is a powerful actuator designed for a variety of medical applications.
It is developed for both push and pull applications and has a very robust construction
because of the ultrasonic welded plastic housing.
Usage:
• Duty cycle: 2/18; 2 minutes continuous use followed by 18 minutes not in use
• Ambient temperature: +5
o
C to +40 oC (the actuator must also be at this temp.)
• LA27 is approved according to IEC 60601-1, ANSI/AAMI ES 60601-1 and
CAN/CSA C-22.2 No. 60601-1
• With connection to a static voltage power supply of 33V the lifetime could be
reduced to 5000 cycles (at a constant load of 6000 N).
NOTE: Re. LA27 with 6.000 N specification (274x3xxx1xxx0xZ; Z = A or B with worm shaft*) for OpenBus™.
This combination reduces the self-lock ability because of lower friction from the worm shaft which has a rolled axle. This worm shaft is however
needed because of the OpenBus™ output power.
The self-lock ability may be reduced in cases where the load curve is 6.000 N in both minimum and maximum stroke length.
*) Z as type “0” does not use the rolled worm shaft. However, type “0” is NOT compatible with the transformer used for OpenBus™ CBs.
Recommendations
• LA27 is not meant to have CB6S OBF mounted on the actuator. The CB6S OBF must be mounted separately using a bracket.
• LA27 must have a minimum installation dimension of 320 mm if control box CB6 is to be mounted on the actuator.
• The cable for the LA27 is not part of the actuator therefore it must be ordered separately.
• Piston rod eye: The distance from the centre of the eye, to the end of the actuator.
• Change between push and pull not allowed
• Inspect actuator once a year, for wear and jarring sound.
• We recommend using a safety nut in medical applications
• Do not expose actuators without all cables fitted to water/cleaning.
• No thread on bolt inside back fixture.
Note: For CB6, the current will be cut off when the total current on all channels reaches approx. 5.1 to 5.4 Amp.
This means that when two LA27s, running simultaneously, are connected to a CB6, they will not be able to lift the max. load mentioned under
technical specifications.
Ratchet Spline:

Mounting of the release cable:
Remove the quick release cover, and the
cable mounting holes can be seen.
Mount the cable in one of the cable mounting holes

Application requirements:
To avoid damage to the LA27 with QR, it is necessary for certain parameters to be specified in the application.
You should therefore be aware of the following facts when supplying an LA27QR to a customer.
Constant pressure on the actuator:
• The QR concept is such that the actuator can pull with max.100 N. Therefore there must always be a load on the actuator when it is run inwards
to ensure correct operation.
• When the QR is activated there must be a minimum load on the actuator in order to ensure that the actuator runs inwards.
This load is depends on the spindle pitch: 5 mm must have 750 N load. 6 mm must have 500 N load.
Mechanical stop in the application:
• When the QR is activated the actuator will run inwards, until it blocks. Depending on the specification, the actuator will run inwards until either
the spindle nut runs against the sliding bearing or when the end plug of the inner tube runs against the spindle.
• The solution is not constructed to absorb the impact that can occur when the QR is activated and the actuator is driving into endstop with a
heavy load.
• Therefore there must be a mechanical stop built into the application to stop the movement 5mm before the actuator runs into endstop and blocks.
Activation of QR function:
• If the QR is activated at the same time as the actuator is running, then in order for the QR parts to get into position, it may be necessary first to
run the actuator in an inward direction using the handset until the QR parts are in place.
Use of the QR function:
• LA27 with QR is designed to be used as part of the back rest function on a bed. When a situation occurs where the patient in the bed has to lie
down as quickly as possible, the QR function is activated and the back rest can be lowered, when the actuator is no longer in motion the QR
handle is released.
Locking plate must be mounted:
• To ensure that the Bowden cables are fixed correctly the locking plate must be mounted.
Quick Release cable dimensions:
• The release cable has to be provided by the customer.
• The force required to operate the Quick Release is approx. 1 - 28 kg., depending on the actuator load.
• When operating the Quick Release function, the Quick Release must be activated all the way down and not stopped halfway!
• The Quick Release can only be ordered with 5 and 6 mm pitch.

Page 50
Mounting bracket instructions:
To avoid damage to the actuator when the actuator is in the “rest” position there should be no load / tension on the actuator.

7. LA28 ( MEDLINE® CARELINE® HOMELINE®)
The LA28 is primarily a system actuator. The actuator is very quiet and powerful designed
for use in the furniture, rehabilitation, and hospital bed line of businesses.
The actuator is also ideal for use in agricultural machinery and for a wide range of
industrial applications.
Reed-switch:
Reed-switch gives a number of pulses for each rotation of the motor. These pulses are
used to calculate the piston rod’s position as well as to control several actuators running
in parallel.
Your nearest LINAK dealer can inform the number of pulses per stroke length.
Regarding Reed-switch connection, Figure 6.8 (LA28R)
Built-in end-stop circuit (CS28/CS28S)
In the LA28 actuator, with built-in CS28 A-, B- or C-PCB, the actuator is switched off at the end position or when overloaded.
LA28 actuator with:
• The CS28 A is standard IPX1 and is connected to a HB41 hand control with a telephone plug.
• The CS28 B is standard IPX5 and is connected to a HB41 hand control with a DIN plug. CS32 B is also available in IPX6.
• The CS28 C is standard IPX1 and is connected to an external contact or control. See figure 6.7.
Mechanical spline:
The splines function so that the actuator can only push, not pull. During pull in the actuator, the inner tube is lifted off the thread bush, and the
actuator can therefore never pull a load, only push.
Functional test of mechanical splines:
When the piston rod is at the innermost position, it must be possible to pull it out manually to its full travel length and to press it in again without
much resistance and without using the motor. If this is not possible, contact your nearest LINAK dealer.
Warning
Do only use the actuator within specified working limits.
Usage:
• Duty cycle: Max. 10 % or max. 2 min. continuous use followed by 18 min. not in use.
• Ambient temperatures: + 5 °C to + 40 °C
• Compatibility: CB8, CB12, CB14, and CBJ
• Approvals: IEC 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-22.2 No 60601-1
Recommendations
• LINAK control boxes are designed so that they will short-circuit the motor terminals of the actuator(s), when the actuator(s) are not running.
This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box, the terminals of the
motor must be short-circuited to enable self-locking of the actuator.
• The maximum load in pull is 2000 N.
• Min. stroke length for the LA28 with splines is 80 mm
• The current supply to LINAK actuators must be cut off in case of overload and when the actuators reach end position.
• Ambient operating temperature is 22 °C.
• LA28 Compact cannot be used in pull applications, unless fitted with an aluminium back fixture.

8. LA28 Compact ( MEDLINE® CARELINE® TECHLINE®)
The LA28 Compact is a small and powerful actuator designed for use in system
solutions for healthcare equipment or industrial applications. Ideal applications are for
example wheelchairs, treatment chairs, patient lifts or beds.
Usage:
• Duty cycle: Max 10 % or max. 2 min. continuous use followed by 18 min. not in use.
• Ambient temperatures: + 5 °C to + 40 °C
• Compatibility: CB8, CB12, CB14 and CBJ
• Approvals: IEC 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-22.2 No 60601-1
Recommendations
• *LINAK control boxes are designed so that they will short-circuit the motor terminals of the actuator(s), when the actuator(s) are not running.
This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box, the terminals of

9. LA29 (HOMELINE®)
The LA29 actuator is a HOMELINE® actuator specially made for domestic applications.
The actuator has a very short installation dimension as the distance between the two
fixing points is small when the actuator is retracted and at the same time independent
of the stroke length. This feature makes the actuator ideal as a lifting actuator for
self-lifting recliners.
Another special feature here is the flexible back fixture, which can adapt misalignments in e.g. a recliner application.
The LA29 is compatible with various HOMELINE® control boxes.
Reed switch:
The Reed switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the position as well as to control several actuators running in
parallel.
Your nearest LINAK dealer can inform the number of pulses per stroke length.
Regarding Reed-switch connection, see Figure 6.10.
Hall
The Hall principle is very similar to the Reed principle. A Hall sensor is based on a magnet that rotates. Two hall sensors are placed close to the
magnet field. The control box (CB20/CB6S OBF/CB16 OBF/CBD4/CBD5) can detect whenever the magnetic field changes direction.
The two Hall sensors are placed close to each other, but with a small displacement. This distance leads to a timing difference between the two pulses.
Whichever one of them comes first indicates the direction of movement. Therefore, there will be no error summary (as with the reed switch) Hall is
therefore a very precise system. Hall is not suitable for use in quick release actuators - see figure 10.
Built-in end-stop circuit
The end-stop switch is part of the actuator construction. Each time the actuator reaches end-stop position the switch is activated and the current is
cut off.
Warning
Do only use the actuator within specified working limits.

10. LA30 (MEDLINE® CARELINE® TECHLINE®)
The LA30 is a powerful actuator yet small enough to fit most applications.
The actuator can be supplied with options such as built-in potentiometer for servo
operation or an extra powerful motor for increased speed and strength (S-motor).
In addition to industrial and agricultural applications, the actuator is also ideal for
positioning satellite dishes.
Usage:
• Duty cycle: 10 %, 2 minutes continuous use followed by 18 minutes not in use
• Ambient temperature: + 5 °C to + 40 °C
• Storage temperature: - 40 °C to + 70 °C
• Compatibility: CB8, CB12,
• Approvals: IEC 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-22.2 No 60601-1
• Should the LA30 be used with a non LINAK control unit, please ask the nearest
LINAK representative for further details
Recommendations
LINAK control boxes are designed so that they will short-circuit the motor terminals (poles) of the actuator(s), when the actuator(s) are not running.
This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box the terminals of the motor
must be short-circuited to achieve the self-locking ability of the actuator.
Improved self-locking ability
The H-bridge ensures that the motor is shorted when the relays are incactive.
This is necessary to improve the self-locking of the actuator.
When using the LA30 with stereo jack plug be aware of the reversed direction of travel as standard.
The current supply to LINAK actuators must be cut off in case of overload when the actuators reach end position.

11. LA31 (MEDLINE® CARELINE
®
The LA31 is a compact, quiet and powerful actuator designed for a variety of applications
in the MEDLINE® & CARELINE® segment, such as hospital beds, couches and nursing
home beds.
The standard LA31 actuator features known parts such as piston rod eye with slot,
and comes in different variations with e.g. fast motor, hall positioning and emergency
lowering. The LA31 actuator has exchangeable cables and is ideal in combination with
OpenBus™ control boxes.
The LA31 actuator has an ingress protection of IPX6 and is available in version with up
to 6000N in push and 4000N in pull.
Usage
• Duty cycle: Max 10 % or 2 minutes continuous use followed by 18 minutes not in use
• Cycles: The LA31 life cycle test has been performed with a stabilised power supply
(10 % duty cycle) on a 200 mm stroke actuator at max. load for 10,000 cycles
(at ambient temperature)
• Ambient temperature: + 5 °C to + 40 °C
• Approvals: IEC 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-22.2 No 60601-1
To avoid damage to the actuator
When the application is in the “rest” position there should be no load/tension on the actuator.
If electrical end stop fails to function the actuator will continue to retract or extend until mechanical end stop is reached.
The application of the customer must be able to obtain or withstand an actuator with failing electrical end stop.
Minimum length of actuator reaching mechanical end stop: nominal BID - 7 mm.
Maximum length of actuator reaching mechanical end stop: nominal BID + nominal SL + increase + 7 mm.
Mounting bracket instructions:
Piston rod
Application mounting bracket
Note the recommended design for the mounting bracket hole.
• LA31 with internal quick release types A and B is not designed for use in pull.
• The necessary release force on an actuator with 5mm pitch is 75 kg for 6 mm pitch = 50 kg.
• LA31 with quick release is always with brake (push).
• The flexible back fixtures (05 or 06) must be standard when the LA31 is equipped with quick release.
• When operating the QR function of QR types A and B, the QR must be activated all the way down. Otherwise the QR will no longer function.
Mounting of the release cable:
Fig 1. Removal of QR cover.
Use only light pressure near the snap-on
flanges to lift the cover.

Max. angle of movement:
Note: To ensure operation the Quick Release must be rotated
o
45
C (max.) due to tolerance/load variation. Some units may
operate before 45 oC is reached.
To avoid damaging the QR, it should not go above 45 oC.
Drawing no.: 031944
Recommendations
• The release cable has to be provided by the customer.
• The design of the release cable has to be as specified.
• It is important to observe the max. active (the moving part of the cable) cable length of 12 mm.
Do not pull more than this length otherwise the QR will be damaged!
• The force required to operate the Quick Release is approx. 5 kg.
• When more than the recommended 5 kg force is used to activate the QR, more friction will be created in the internal actuator/QR mechanism.
This means that a greater load will be required to ensure successful operation.
• The QR cover is supplied attached to the actuator but not mounted.
• LA31 with external quick release, types I, K, L, and M can maximum pull 200 N.
• The necessary release force on an actuator with 5 mm pitch is 75 kg for 6 mm pitch = 50 kg.
• It is not possible to combine splines with the external quick release.
• LA31 with quick release is always with brake (push).
• The flexible back fixtures (05 or 06) must be standard when the LA31 is equipped with quick release.
• LA31 with brake. An LA31 brake in a push application brakes actively when the actuator moves in an inward direction. The same applies to an
actuator mounted with a brake in a pull direction. It brakes in an outward direction. Under this condition the standard motor uses up to 4 Amp.
and the fast motor uses up to 6 Amp. (Measured after 5 cycles at normal room temperature).
Therefore if the LA31 with brake is used together with a CB7 it is important that the current cut-off limit of the control box is higher than the used
Amp. i.e. not lower than 4 Amp.
LA31 with brake cannot be combined with CB9/CB7 with emergency lowering. For all LA31 actuators with brake self-locking ability up to max.
load it is only possible in one direction: push or pull.
• The LA31 actuator must not be exposed to more than 4000 N in pull. In applications where misalignments may occur the normal back fixture can
take max. 1500 N in pull whereas the flexible back fixture can take up to 4000 N in pull.
The actuator must be mounted at right angles (90
o
C) to it is fixing/load (max.1.5 oC deviation)
• LA31 actuators with protection class IPX6 must be mounted with the screw holes mounted facing downwards. To ensure that any water remaining
from cleaning / washing is not collected in the screw holes.

Page 56
Warning
• If an LA31 is used in an application where there are repeated dynamic (push/pull) movements in the area 2000 - 4000 N, then it is necessary to
contact LINAK A/S in order to make a correct specification of the actuator. Repeated push/pull movements cause extra strain to the actuator and
can give safety considerations, the consequence being possible damage to the actuator.
• The LA31 actuator must not be exposed to more than 4000 N in pull. In applications where misalignments may occur, the normal back fixture
can take max. 1500 N in pull, whereas the flexible back fixture can take up to 4000 N in pull.
• The actuator must not be used in pull applications when the Quick Release is activated, as the risk of personal injury can arise.
• Bowden cable must click twice, in order to be locket sufficiently.
• Do not sideload the actuator.
• Inspect the actuator minimum once a year for wear and jarring sound.
• If a LA31 is used in an application where there are repeated dynamic (push/pull) movements in the area 2000 - 4000 N, then it is necessary to
contact LINAK A/S in order to make a correct specification of the actuator. Repeated push/pull movements cause extra strain to the actuator and
can give safety consideration, the consequence being possible damage to the actuator.
LA31 actuators for patient hoists are marked with a label to ensure the user is aware that it is not permitted to handle the patient hoist
by pulling the actuator or otherwise expose it to side forces.
LA31 with mechanical end stop - a first failure safe option:
In many applications our customers have approvals according to EN 60601-1.
The typical applications can be beds, massage couches etc.
In the norm, EN 60601-1, it is mentioned that the application must be first failure safe.
The manufacturer is responsible for making a risk analysis in order to check this. If a risk is identified it is the manufacturer of the application who
makes sure that the risk is eliminated.
Normally the result of this risk analysis will state that the end stop switch in the LA31 would be questioned: Is this switch first failure safe?
The answer to this will be: No, a switch cannot be first failure safe. - In practical life we have discovered only very few defect switches.
Ask the customer: - What was the result of your risk analysis when you achieved the EN 60601-1 approval on your application?
There are several ways that an application can be made first failure safe:
• Use a mechanical stop in the application
• Use of a mechanical end stop in LA31 - is a possible option.
• Use an SLS (safety limit switch) in connection with the actuator.
• As a special solution we can offer LA31 with mechanical end stop with the same installation dimension as a standard LA31.
Contact LINAK A/S for further information if you need this solution.
LA31 with manual lowering
The purpose of the ML (Manual Lowering) is in case of a power failure, to be able to mechanically lower a patient by turning the ML part in the
clockwise direction until the actuator is fully lowered.
Recommendations:
• An addition of 35 mm to installation dimension compared to standard (with spline)
• Only for push applications
• Use spline actuators
• Cannot be retro fitted

12. LA32 (MEDLINE® CARELINE®)
The LA32 actuator is a powerful actuator that can be supplied with a ball screw
spindle to give outstanding performance. The ideal choice for a wide range of
applications including adjustment of hospital beds.
The LA32 actuator has many special options including a safety nut, splines, quick
release (F) and an optional protection up to IPX6 standard.
Reed-switch:
The Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Your nearest LINAK dealer can inform the number of pulses per stroke length.
Regarding Reed-switch connection, see Figure 6.10.
Usage:
• Duty cycle: Max. 10 % or 2 minutes continuous use followed by 18 min. not in use
• Ambient temperature: + 5 °C to + 40 °C
• For use with LINAK control boxes CB8, CB12, CB14 and CS16 PCB or internal CS32 PCB
• Approvals: IEC 60601-1:2005, 3rd edition, ANSI / AAMI ES60601-1:2005, 3rd edition and CAN / CSA-22.2 No 60601-1:2008 approved
Recommendations
• The piston rod eyes are “crimped” in place and cannot be screwed loose.
Protective cap
“Crimped” piston rod eye Piston rod without eye
• Piston rods without eyes have not been tested
• LA32 with quick release and free wheeling function must not be sold to new products
Maximum load in pull = 2000 N
LA32 actuators for patient hoists are marked with a label to ensure the user is aware that it is not permitted to handle the patient hoist
by pulling the actuator or otherwise expose it to side forces.
Freewheeling of piston rod
All LA32 actuators with freewheeling as well as with quick release have the designation W on the label.
The function causes the following:
• The piston rod can be pulled out with a thrust of approx. 300 N and it remains in the new position without declutching.
• The actuator cannot pull, but only push.
Functional test:
It must be possible to pull the piston rod out with a thrust of approx. 300 N and it must remain in the new position without releasing. If this is not
possible, contact your nearest LINAK dealer.
Built-in end-stop circuit (CS32)
In the LA32 actuators, with built-in CS32 A-, B- or C-PCB, the actuator is switched off at the end position or when overloaded.
LA32 actuator with:
• The CS32 A is standard IPX1 and is connected to a HB41 hand control with a telephone plug.
• The CS32 B is standard IPX5 and is connected to a HB41 hand control with a DIN plug. CS32 B is also available in IPX6.
• The CS32 C is standard IPX1 and is connected to an external contact or control. See Figure 6.7.
Page 57 of 192
Page 58
Mechanical spline:
The splines function so that the actuator can only push, not pull. During pull in the actuator, the inner tube is lifted off the thread bush, and the
actuator can therefore never pull a load, only push. See figure 8.
Functional test of mechanical splines:
When the piston rod is at the innermost position, it must be possible to pull it out manually to its full travel length and to press it in again without
much resistance and without using the motor. If this is not possible, contact your nearest LINAK dealer.
Electrical splines:
In the rear fixture on the actuator, a microswitch is fitted, which turns off the motor, if the actuator is exposed to pull forces.
Functional test of electrical splines
When the actuator is correctly fixed/mounted, the inward movement of the piston must stop, when the actuator is pulled or the movement is blocked,
so that the back fixture is not put under undue stress/tension. For mounting, see Figure 7.
Quick release
When the quick release arm, see Figure 9, is turned counter clockwise approx. 75° and fixed here, the piston rod is released and can now be
pressed in to its innermost position or pulled out to its outermost position. When the quick release arm is released, the arm turns back and the
actuator functions normally again. The cable must not be tight.
Warning
• If the actuator does not work as described above, the risk of injury due to squeezing can arise. Therefore, the actuator must immediately be sent
for service at the nearest, authorised LINAK workshop.
• The actuator must not be used in pull applications when the quick release is activated, as the risk of personal injury can arise.
• Do only use the actuator within specified working limits.
13. LA34 (MEDLINE® CARELINE®)
LA34 is a technological state-of-the-art actuator that, due to its innovative construction
can push up to 10000 N at a speed of 5 mm/sec. and with a current consumption of
approx. 7 Amp. The strong LA34 actuator is made in a low weight composite material.
Its compact design, the outstanding performance and a wide range of safety options
makes LA34 the right choice for a variety of medical and industrial applications.
The LA34 24V actuator is approved according to IEC 60601-1, ANSI / AAMI ES60601-1,
and CAN / CSA-22.2 No 60601-1.
Reed-switch:
The Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Your nearest LINAK dealer can inform the number of pulses per stroke length.
Options:
Regarding Reed-switch connection, see Figure 6.10.
• Mechanical spline: When using the actuator in a vertical position, the force needed to activate the mechanical spline is maximum 60 N + the
weight of the application. To reengage the spline function, a force of maximum 60N is needed. Same installation dim. as standard actuator.
• A modified Bowden cable holder is available (as a special article), with better cable alignment and improved guidance of the cables.
• Electric spline: When using the actuator in a vertical position, the force needed to activate the electric spline is maximum 100 N + the weight
of the application. To reengage the spline function, a force of maximum 100 N is needed.
Usage:
• Duty cycle: 2/18 – 2 minutes continuous use followed by 18 minutes not in use
• Ambient temperature: + 5 °C to + 40 °C
• Compatibility: CB9 with EAS, CB12 with EAS, CB14*, CB18, CB20 and CBJ, CB6 OBL/ F, CB16 OBL/ F,
(* = only possible with customized software)
• Approvals: IEC60601-1, ANSI / AAMI ES60601-1 and CAN / CSA-22.2 No 60601-1 for LA34 24V zinc and composite versions.
Recommendations
• Power supply without current cut-off can cause serious damage to the actuator if mechanical stop is encountered or the actuator movement is
blocked in another way.
• LINAK control boxes are designed so that they will short-circuit the motor terminals (poles) of the actuator(s) when the actuator(s) are not running.
This solution gives the actuator(s) a higher self-locking ability. If the actuator(s) are not connected to a LINAK control box the terminals of the
motor must be short-circuited to achieve the self-locking ability of the actuator.

Warning
An LA34 actuator is not designed for repeated dynamic push-to-pull movements. This cause extra strain to the actuator and can give safety
considerations, the consequence being possible damage to the actuator. Therefore, if repeated dynamic push-to-pull movements are essential
for the application, perform tests to validate the performance and use a steel piston rod eye (contact LINAK A/S).
LA34 actuators for patient hoists are marked with a label to ensure the user is aware that it is not permitted to handle the patient hoist by
pulling the actuator or otherwise expose it to side forces.
Tests show that uneven running can occur when retracting the LA34 composite actuator with a low load below 500N.
This has no impact on the safety of the actuator and is caused by internal frictions.
If the LA34 actuator is used in connection with a non-LINAK power supply the system must be equipped with current trip cut-off.
Adjustment of the installation dimension N
As standard the installation dimension on the LA34 actuator can be manually adjusted by +4 / -0 mm (not possible for mechanical splines).
The adjustment of the installation dimension must only be made without use of tools only, or hand). It is not allowed to use tools to adjust the
installation dimension of the LA34 actuator as there is a risk that the inner tube may be unscrewed.
Hall
The Hall principle is very similar to the Reed principle. It is a control box, which based on Hall signals, can decide whether the actuator runs out or in.
Hall, however, can detect whether the actuator runs in or out. The number of pulses is like Reed. Hall and Reed are placed opposite the potentiometer
on the actuator’s worm wheel. Therefore, it is not suitable for use in quick release /free wheelingactuators. see figure 10.
Potentiometer
The potentiometer function is mechanically attached to the spindle and registers the number of spindle revolutions. The signal from the potentiometer
is measured in Ohm, where the lowest value is measured when the actuator has been run into inward switch stop. The potentiometer is a 10 - turn
and therefore it is dependent on the stroke length/spindle pitch. see figure 6.5
Mechanical spline:
The splines function so that the actuator can only push, not pull. During pull in the actuator, the inner tube is lifted off the thread bush, and the
actuator can therefore never pull a load, only push. See Figure 8.
Functional test of mechanical splines:
When the piston rod is at the innermost position, it must be possible to pull it out manually to its full travel length and to press it in again. When
used in a vertical position the force needed to activate the mechanical spline is maximum 60 N + the weight of the application. To reengage the
spline function, a force of maximum 60 N is needed. If this is not possible, contact your nearest LINAK dealer.
Electrical splines:
In the rear fixture on the actuator, a microswitch is fitted, which turns off the motor, if the actuator is exposed to pull forces.
Functional test of electrical splines
It is important that the actuator is correctly fixed with regard to the section on page 11. For mounting, see Figure 7.
When the actuator is correctly fixed/mounted, the inward movement of the piston must stop, when the actuator is pulled or the movement is blocked,
so that the back fixture is not put under undue stress/tension.
Quick Release
LA34 (34xxxF/H) is equipped with a function which permits operation of the actuator should the power source fail. Condition for functioning: the
actuator must be loaded in push direction (LA34xxxF) or pull direction (LA34xxxsH).
Warning
• If the actuator does not work as described above, the risk of injury due to squeezing can arise. Therefore, the actuator must be sent immediately
for service at the nearest, authorised LINAK workshop.
• The actuator must not be used in pull applications when the Quick Release is activated, as the risk of personal injury can arise.
• Do only use the actuator within specified working limits.
Activation of Quick Release
Pull the release handle in the direction of the piston rod eye (outwards), the harder you pull the button the quicker the actuator runs down.
When releasing the button the emergency lowering stops immediately. The emergency lowering is activated as long as the load on the actuator is
above 100 - 150 kg. The actuator is ready for normal use when the emergency lowering is finished.
Safety device regarding functional failure of the nut (Safety nut):
The LA34 has a built-in safety nut in push as standard and is available with a safety nut in pull as an option. Actuators with safety nut in push can
only function when used in push applications. The safety nut comes into operation should the main nut fail.
Afterwards it is only possible to drive the actuator into the innermost position. Safety nut in pull is for pull applications and works the opposite way
as described above. Thereafter, the actuator will not function any more and must be sent for service.
Built-in end-stop circuit
In the actuators mentioned the end-stop switch is part of the actuator construction. Each time the actuator reaches end-stop position, the switch is
activated and the current is cut off.

The application of the customer must be able to obtain or withstand an actuator with failing electrical endstop.
Minimum length of actuator reaching mechanical endstop: BID - 7 mm.
Maximum length of actuator reaching mechanical endstop: BID + SL + 7 mm.
Recommendations
• Power supply without current cut-off can cause serious damage to the actuator if a mechanical stop is encountered or the actuator movement is
blocked in another way.
• Connection bolts must be dimensioned so that they have the necessary strength and tolerance in order to obtain the minimum safety factor
according to the requirements of the authorities.
• The actuator must not be subject to a side load, as this can cause bending / collapse of the actuator. The actuator must never be used as a handle.
• The actuator must not be subject to off-centre loading, as this can cause bending / collapse of the actuator.
• The actuator must not be subject to impact, or any form of stress to the casing.
• The actuator must not be subject to overload, as this can reduce the lifetime of the actuator and in the worst case cause damage to the actuator.
• The actuator must never be used in dynamic pull applications, as this can cause collapse.
• Only use the actuator within the specifications.
• Connection bolts and brackets are to be inspected in connection with service, and must be replaced if there are signs of wear.
• Ensure that the cable lock is mounted correctly.
• Ensure that the duty cycle and the usage temperatures for LA40 actuators are respected.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.
• The LA40 is not suitable for use in outdoor applications where it can be exposed to sun and rain.
Warning
• The installation of spline actuators is recommended by LINAK where possible to avoid the squeezing of body parts.
• End of life issue: defective switches - endstop:
If the electrical endstop switch for outward operation fails, it may cause a prolonged actuator stroke and in addition the customer application
may collapse. To avoid this, the manufacturer must take this into account when designing and making a risk analysis.
Instruction concerning the turning of the piston rod eye
When mounting and taking into use, it is not permitted to turn the piston rod eye several times.
In cases where the eye is not positioned correctly, the eye must be screwed to its bottom position
(1) and then maximum half a turn outwards again (2).
Mounting bracket instructions
To avoid damage to the actuator, it is important that the acutator drives to the application endstop
position and continues to operate in the groove until it activates the electric actuator endstop.

• The LA40 is not suitable for use in outdoor applications where it can be exposed to sun and rain.
• LA40 with mechanical endstop - a first failure safe option:
In many applications customers have approvals in accordance with EN 60601-1. The typical applications are beds, massage couches etc. The norm
EN 60601-1 states that the application must be first failure safe. The manufacturer has the responsibility of carrying out a risk analysis in order to
check this. If a risk is identified, the application manufacturer must ensure that this risk is eliminated. A switch cannot be first failure safe.
• If there is a risk of “pull forces” in the application, the actuator must be equipped with spline functionality to avoid damage in pull.
• Patient lift and stand aids:
- Long installation dimension: must always be used for patient lifts
- Do not hold the inner or outer tube while the actuator is running. There can be a risk of squeezing between the manual lowering unit and the outer tube.
- Always use the ratchet spline functions for patient lifts.
• LA40 8000 N PL actuators for patient lifts are marked with a label to ensure that the user is aware that it is not allowed to pull the
actuator or otherwise expose it to side forces when handling the patient lift.

4. Information on specific columns
1. BB3 (MEDLINE® CARELINE®)
Warning
Do only use the column within specified working limits.
2. BL1 (MEDLINE® CARELINE® TECHLINE®)
The BB3 3-part telescopic actuator is the ideal choice for vertical lift of beds where
design and easy integration in the customer’s guidance ensures optimum freedom of
design.
The BB3 is a 3-part telescopic actuator designed to meet EN 1970 for care beds, which
demands an adjustment range from 350 mm up to 750 mm.
Reed-switch:
The Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Your nearest LINAK dealer can inform you of the number of pulses per stroke length.
Regarding reed-switch connection, see Figure 6.10.
• The columns must be securely mounted before operation, no rotation must be possible
• The motor housing must be mounted uppermost.
The BL1 is a 3-part lifting column designed to be used for example in hospital beds,
nursing home beds, treatment chairs, couches and dental chairs.
The lifting column is compact and has a long stroke length. The 3-part guidance enables
an overlap between the individual profiles, which ensures a high degree of stability.
The lifting column has an open spindle actuator with a chain drive inside which is
practically noiseless.
Usage:
• Duty cycle: 10%, 2 minutes continuous use followed by 18 minutes
not in use
• Usage temperature: + 5 °C to + 40 °C
• Storage temperature: Max 50 °C
• Compatibility: CB6 OBL, CB6 OBF, CB16 and CB20
• Approvals: IEC60601-1, ANSI/AAMI ES60601-1,
CAN/CSA-22.2 No 60601-1
IEC 60601-1-6
IEC 60601-1-2
Input/output specifications: dual Hall, digital positioning
Column with Dual Hall (BL141H) are equipped with two hall sensors, A and B and a spindle magnet. In this way you can have pulses from the
column when it moves.
The feedback system has a 8P magnet which gives 16 shifts in pulses per spindle turn.
Page 72 of 192
Page 73
Hall Output:
4 mm spindle = 0,25 mm per pulse and 400 pulses per 100 mm stroke.
9 mm spindle = 0,5625 mm per pulse and 178 pulses per 100 mm stroke.
Important:
The motor must always be short-circuited to obtain self-locking in accordance with the rated label value.
Recommendations
• Please follow the important BL1 mounting guidelines.
• Max. storage temperatures: +50 °C.
• BL1 is for use in push applications, cable outlet from smallest profile (top) or biggest profile (bottom). See top and bottom plate dimensions.
• When washing according to IPX6 parameters, it is not allowed to splash water directly onto the plastic frames between the profiles.
Direct splashing is only permitted on the aluminium profiles. Alternatively, BL1 can be mounted upside down with the largest profile at the top.
In this configuration, no IP rating applies.
Warnings
• BL1 is heavy (9.8 kg) To avoid personal injury, DO NOT DROP !
• Do not adjust anything during movement, can cause personal injury !
• LINAK recommend using a safety nut in medical applications !
• A broken chain causes a drop of half the length of actual stroke. Therefore do not overload !
• The BL1 is designed for use in push applications, dynamic “Pull forces” can result in damage to the column and cause collapse of the application.
• Do not loosen any screws on the BL1, this can cause collapse of the column !
• LINAK recommends making regular measurement of Class 1 protective ground conductivity in the application to avoid a disconnected grounding
cable. Worn out or defect parts must be replaced.

BL1 Mounting guidelines:
• BL1 is for use in push applications, and can be mounted in both directions (smallest profile down, or up).
Note: The cable outlet can be positioned at the top (smallest profile). If the option with integrated cable is chosen, the cable outlet can
also be positioned at the bottom (biggest profile).
• It is very simple to mount the BL1 in the application using the 4 mounting holes in both endplates.
• Use 4 self-tapping screws, in each end, for mounting to the application. Use EJOT PT type DG Ø8, screw depth must be min. 30 mm in
aluminium profile. Screw torque: 15 - 17 Nm.
• If the column has been loosened from the application, it is very important that the self-tapping screws are mounted in the same thread,
to ensure the same strength in the thread. Therefore we recommend that the screws are loosened no more than 1 or 2 times.

Recommendations
• The mounting plate in the application must cover the entire top plate of the BL1 and be strong enough to carry the load.
• Remember to secure the cable mounted in the top of the column to the application, so that it cannot be pulled out of the column.
We recommend to use LINAK Cable:
- Lock kit for BL1 with motor cable: 0808040
- Lock kit for BL1 with hand control cable through: 0808046
Use only the screws included in the kit.
• For motor cable mounted at the top, use the long screw with the coarse thread.
Screw torque 1.7 Nm.
• For motor cable mounted at the bottom and for cable through, use the short screw with the fine thread. Screw torque 2.7 Nm.
• Electro Static Discharges!
There is no electrical connection through the length of the BL1 column. Therefore, to avoid ESD issues, consider external potential alignment
between the top and bottom of the bed frame.
To connect for further earth wiring in the application, use an appropriate ø8 mm cable shoe under one of the 8 mm screws at both the top plate
and the bottom plate.
• Remember to mount the blind plugs in the top plate if the motor cable is connected from the bottom plate to ensure the IPX6 protection.

When mounting more than one BL1 you need to consider the fixation:
Fixed pivot point
Moveable pivot point
Example 1.
Fixed pivot point
Fixed pivot point
Example 2.
The reason why it is important only to fix one column, is that the columns will not move exactly in parallel – even if you have positioning such as hall.
If more than one column is fixed it can lead to dangerous situations.
If you have a trend/anti-trend function in your application, you need to mount one or more BL1s with a slider.
Having sliders prevents the column from bending as illustrated below.

3. BL4 (MEDLINE® CARELINE®)
The BL4 is a 4-part lifting column specially designed for hospital and care beds; the
BL4 can of course be used for other applications where a compact lifting column with
a long stroke length is needed.
The lifting column is based on the BB3 actuator, which is practically noiseless. The
specifications comply with the demands to the lifting functions in beds as to load,
speed and stroke length.
Reed-switch:
Reed-switch gives a number of pulses for each rotation of the motor. These pulses
are used to calculate the piston rod’s position as well as to control several actuators
running in parallel.
Usage:
• Duty cycle: up to 10% or max. 2/18 min.
• Ambient temperatures: + 5 °C to + 40 °C

• There are mounting holes in the endplates and motor housing
• The columns must be securely mounted before operation, no rotation must be possible
• The motor housing must be mounted uppermost
• The mounting bracket tension must be adjusted correctly
Warnings
• Do only use the column within specified working limits.
• The BL4 is heavy (8.2 kg) To avoid personal injury, DO NOT DROP!
• Do not adjust anything during movement, can cause personal injury!
• The BL4 is designed for use in push applications, dynamic “Pull forces” can result in damage to the column and cause collapse of the application.
• Do not loosen any screws on the BL4, this can cause collapse of the column!
• IPX6 washable versions must not be dismantled and then rebuilt again without the motor housing being changed in order to ensure the washability.
• There must be at least 4 hours between each washing cycle to allow the BL4 to resume normal temperature.
Recommendations
• Max. storage temperatures: +50 °C.
• BL4 is for use in push applications only and only mounted with the motor housing uppermost.
• Actuators using “buffer” end-stop principle are not compatible with BL4 and CB9 systems.
• If the column is driven in end-position (end-stop switches in the actuator will be activated ) and if the hand control is kept activated you will in
some cases, depending on the column load, see that the actuator starts and stops as long as the hand control is activated.
Recommendations with washable versions:
• IPX6 Washable versions must not be dismantled and then be rebuilt again without the motor housing being changed in order to ensure the washability.
• There must be at least 4 hours between each washing cycle to allow the BL4 to resume normal temperature.
Page 78 of 192
Page 79
BL4 Mounting guidelines:
• The BL4 must always be mounted vertically before operation and always vertical with the motor housing uppermost.
(Otherwise, the internal end-stop switch system can break due to rotation).
• Both the motor housing and the bottom tube (the one with the largest diameter) must be secured in the application in such a way
that no rotation can occur.
• It is recommended to monitor the current consumption in order to determine the necessary tensioning force for the mounting bracket.
If the current consumption rises the BL4 has been tightened too much.
• The mounting plate in the application must cover the entire top plate of the BL1 and be strong enough to carry the load.
• It is recommended that all 4 holes in the motor housing are used to fasten the BL4 to the application.
• The screws must provide a secure fixing e.g. as with self-locking.
• Remember to secure the cable to the housing with a cable tie. Use the fixing eye next to the connector socket.
On the BL4 cables, clip sleeve are mounted, they need to be removed.
• Electro Static Discharges!
Be aware that there is no electrical connection through the length of the BL4 column. Therefore, to avoid ESD issues, consider external
potential alignment between the top and bottom of the bed frame.
When mounting more than one BL4 you need to consider the fixation:

Mounting of a product on the side of an LC3
Max. 16
13
M8
It is possible to mount a product on all 4 sides of the LC3 at the same time. However, it requires that the holes for mounting are placed with different
distances from the top and/or bottom plate. Otherwise the mounting screws will collide.
Minimum distance from the top and bottom plate must be observed.
Screws used for mounting of a product on the side of the LC3 must be 8.8.
Screw type M8 M6 M5 M4
Screw torque Nm 17 7 4 2
When mounting more than one LC3 you need to consider the fixation:
The reason why it is
important only to fix
one column, is that the
columns will not move
exactly in parallel – even
if you have positioning
such as hall.
If more than one column
is fixed it can lead to
dangerous situations.
Page 95 of 192
General tolerance +/- 0,5 mm
Drawing no.: 1002w9005
If you do have a trend/
anti-trend function in
your application, you
need to mount one or
more of the LC3’s with
a slider.
Having sliders prevents
the column from
bending as illustrated
below.

• Please follow the important LC3 mounting guidelines.
• LC3 is for use in push or pull applications, cable outlet from smallest profile (top) or biggest profile (bottom). See top and bottom plate dimensions.
• When washing according to IPX6 parameters please notice that the large profile of the LC3 column must be placed upwards (bottom up).
• We recommend making a functional test of the application with all accessories connected before putting it into operation.
• Regular cleaning is recommended to reduce bacteria and increase the hygiene level
• Intended for indoor use only
• Not intended for use in harsh environments like e.g. pool environment, marine environment and agriculture buildings with ammonia vapors.
Warnings:
• Always check correct assembly after mounting and service to ensure that the cable locks are mounted.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress or damages.
• LC3 is heavy (more than 10 kg). To avoid personal injury and product damage, DO NOT DROP!
• Take special precautions concerning 3rd party interfacing. Please contact LINAK for further information.
• Do not exceed the max. pull load specified on the label.
• Do not add dynamic load when changing between pull and push.
• Do not adjust anything during movement or while connected to mains, it can cause personal injury.
• To avoid cable interruption and actuator defects make a proper cable installation and inspect regularly for wear, damage and jarring sound.
Defective parts must be replaced.
• After service inspection, the application must be tested for correct functionality before it is put into operation, to avoid misalignment between
two columns moving in parallel.
• LINAK recommend using a safety nut in medical applications! LC3 has safety nut as standard.
• Do not loosen any screws on the LC3, this can cause collapse of the column!
• LINAK recommends making regular measurement of Class 1 protective ground conductivity in the application to avoid a disconnected
grounding cable. If there are worn out or defect parts, the complete LC3 must be replaced.
• Interconnecting cables must remain plugged in during cleaning to prevent the ingress of water.

5. LP2 (DESKLINE® MEDLINE® CARELINE® TECHLINE®)
The LP2 range of vertical lifting columns is ideal where vertical positioning of
substantial loads is required.
The design allows the LP2 range to be built in a complete motion control system
simply by adding a suitable LINAK control box and hand control.
Advanced design and high quality construction allows the column to be operated
either as single or parallel with up to a maximum of four units and/or with a memory
function.
The LP2 lifting column is the ideal choice for duties such as height adjustment on computer workstations, work benches, or a wide selection of other duties.
• There are mounting holes in the end plates.
• The largest profile must be mounted uppermost.
Warning
Do only use the column within specified working limits.
Warning
Ensure a safe connection between column and application
Warning
Side mounting bracket screws: use the correct torque on the side mounting bracket screws.
Warning
The column can not be used in pull
Warning
Max. bending: LP22 = 550 Nm
LP25 = 1000 Nm

6. LP3 (MEDLINE® CARELINE® TECHLINE®)
The LP3 is developed for vertical lifts and can resist a bending moment by virtue of the
effective telescopic system.
The lifting column is designed for applications where a small installation dimension is
requested without compromising the lifting capacity.
The LP3 is characterised by having a lower installation dimension proportional to the
stroke length compared to the LP2. The LP3 can also attain a higher speed than the
LP2.
The telescopic column is compatible with LINAK’s control boxes and can run individually; as 2 x LP3 parallel and/or with memory.
The LP3 is the perfect choice for height adjustment on dental, gynaecologist, and wheelchairs as well as for operating, office and working benches etc.
The column can only be loaded with the maximum bending moment over the first 80 % of the stroke. The maximum bending moment will
be reduced to 50 %.
The column must be mounted with the largest profile uppermost!
• There are mounting holes in the end plates.
• The largest profile must be mounted uppermost.
Warning
Do only use the column within specified working limits.
Warning
Ensure a safe connection between column and application
Warning
Side mounting bracket screws: use the correct torque on the side mounting bracket screws.
Warning
The column can not be used in pull
Warning
Max. bending: LP3 = 375 Nm
