12. LA40 (HOMELINE
)
®
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 .
Please note that extension of the built-in dimension may reduce the safety factor .
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 - 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 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 .
Turning 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 the bracket
To avoid damage to the actuator, it is important that the actuator drives to the application endstop
position and continues to operate in the groove until it activates the electric actuator endstop .
The LA40 is a low noise and powerful actuator which is available in a 1500 N,
4000 N, 6000 N and an 8000 N version . Based on the extensive knowledge and
experience from previous actuator families, LINAK has developed new gear and
braking principles that improve the efficiency of the new LA40 . These innovative
solutions are covered by several patents .
