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 .
Warning
• The installation of spline actuators is recommended by LINAK where possible to avoid the squeezing of body parts .
• Activation of a quick release can lead to a risk of squeezing body parts . Installation of a damper may reduce this risk .
• A quick release can accidentally be activated during mounting or maintenance . To avoid this, operators must be warned before service/mounting .
• 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 .
• If electrical endstop fails to function the actuator will continue to retract or extend until mechanical endstop is reached .
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 - 5 mm .
Maximum length of actuator reaching mechanical endstop: BID + SL + 5 mm .
• If the actuator does not work as intended, there is a risk of injury . Therefore, the actuator must immediately be sent to the nearest authorised
LINAK workshop for service .
• The actuator is not designed for repeated dynamic push-to-pull movement .
Recommendations
• The LA27 cable is not part of the actuator and must therefore be ordered separately .
• Once a year, the actuator must be inspected for wear and jarring sounds .
• In medical applications we recommend to use a safety nut .
• Do not expose actuators without all cables fitted to water/cleaning .
• The bolt inside the back fixture should have no thread .
• LA27 is not meant to have CB6S OBF mounted on the actuator .
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 .
Instruction concerning the turning of the piston rod eye – LA27
When mounting and taking into use, it is not permitted to make excessively many 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 (1), and
then a maximum half turn outwards again (2) .

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
• LA27 is approved in accordance with IEC 60601-1, ANSI/AAMI ES 60601-1 and
• With connection to a static voltage power supply of 33V the lifetime could be
The product is not designed for dynamic load changes (from push to pull or vice versa .
If the application design requires a product with a dynamic load change capability,
please contact LINAK for investigation of product feasibility or guidance .
