Max. angle of movement:
Note: To ensure operation the Quick Release must be rotated
45
o
C (max.) due to tolerance/load variation. Some units may
operate before 45
o
C is reached.
To avoid damaging the QR, it should not go above 45
o
C.

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
o
C 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.
