Preface Dear User, We are delighted that you have chosen a product from LINAK®. LINAK systems are high-tech products based on many years of experience in the manufacture and development of actuators, electric control boxes, controls, and chargers. This user manual does not address the end-user, but is intended as a source of information for the manufacturer of the equipment or system only, and it will tell you how to install, use and maintain your LINAK electronics.
LINAK application policy The purpose of the application policy is to define areas of responsibilities in relation to applying a LINAK product defined as hardware, software, technical advice, etc. related to an existing or a new customer application. LINAK products as defined above are applicable for a wide range of applications within Medical, Furniture, Desk, and Industry areas.
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.
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.
Chapter 2 Mounting guidelines LINAK® linear actuators are quickly and easily mounted by slipping pins through the holes on each end of the units and into brackets on the machine frame and the load. The mounting pins must be parallel to each other as shown in Figure 1. Pins, which are not parallel to each other, may cause the actuator to bend and be damaged. The load should act along the stroke axis of the actuator since off centre loads may cause bending and lead to premature failure. See Figure 2.
Mounting guidelines • The mounting pins must have the correct dimension. • The bolts and nuts must be made of a high quality steel grade (e.g. 10.8). No thread on the bolt inside the back fixture or the piston rod eye. • Bolts and nuts must be protected so there is no risk for them to fall out. • Do not use a torque that is too high when mounting the bolts for the back fixture or the piston rod eye. This will stress the fixtures. Please note: The piston rod eye is only allowed to turn 0-90 degrees.
Mounting of cables 1. Unscrew the cover and remove the two blind plugs. 2. Plug in the power cable and/or the signal cable. 3. Slide the cover onto the actuator. The torque of the cover screw is approx. 3.5 ± 0.3 Nm TORX 25IP When changing the cables on a LINAK actuator, it is important that this is done carefully, in order to protect the plugs and pins. Before the new cable is mounted, we recommend that the socket is greased with vaseline, to keep the high IP protection and ensure an easy mounting.
Electrical installation • To ensure maximum self-locking ability, please be sure that the motor is shorted when stopped. Actuators with integrated controller provide this feature, as long as the actuator is powered. • When using soft stop on a DC-motor, a short peak of higher voltage will be sent back towards the power supply. It is important when selecting the power supply that it does not turn off the output, when this backwards load dump occurs.
Actuators with I/O Interface Input/Output Specification Comments Description I/O is a universal industrial interface which has been developed by LINAK. I/O is a common term used in the industry, to describe inputs and outputs. Flexibility is key when describing the possibilities of an I/O actuator. A total of six wires are customizable and this opens a world of intelligent actuator control.
Analogue output or digital input Orange Features available: - Analogue feedback (+) - Predefined position 1 - Run condition Light blue Features available: - Analogue feedback (-) - Predefined position 2 Fixed wires Violet Parallel communication Violet wires must be connected together The parallel drive function will support up to 8 actuators running simultaneously. It is possible to run parallel with a single power supply or run each actuator with separate power supplies.

Troubleshooting for Parallel Symptom Possible cause Action Actuators do not move The actuators are not properly connected to the power Check the connection to the power supply or the external supply control unit (if any) Please make sure that the power supply polarity is properly connected, otherwise you might damage the actuator Please see non-critical info below Wrong number of actuators in the system Check if the number of actuators in the system match the number that was ordered Communication wir
Troubleshooting for Parallel Symptom Possible cause Action Actuators run in smaller steps before stop Insufficient power supply Check the power supply while the actuator is running Connect the actuator(s) to BusLink one at a time and check the following: - Reason for last stop (page 62) - Current cut-off levels in both directions After everything is connected, put power on all actuators at the same time.

Chapter 5 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.
