LA32 Actuator with potentiometer LA32 Actuator with reed ( only possible with 24V L-motor )
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.
