10. LA31 (MEDLINE
CARELINE
®
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 .
Exchangeable cables:
When using LA31 with reed feedback in combination with the following control boxes: CB8, CB14 and JUMBO control boxes, please use the
cable type 10A31-X5XXXXX-XXXX-X to avoid control box damage .
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
• 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 .

The LA31 is a compact, quiet and powerful actuator designed for a variety of applications
in the MEDLINE
home beds .
The standard LA31 actuator features known parts such as piston rod eye with slot, and
comes in different variations with e .g . fast motor and hall positioning . The LA31 actuator
has exchangeable cables and is ideal in combination with OpenBus™ control boxes .
The LA31 actuator has an ingress protection of IPX6 and is available in version with up to
6000N in push or 4000N in pull .
Usage
• Duty cycle: Max 10 % or 2 minutes continuous use followed by 18 minutes not in use
• Cycles: The LA31 life cycle test has been performed with a stabilised power supply
(10 % duty cycle) on a 200 mm stroke actuator at max . load for 10,000 cycles
(at ambient temperature)
• Ambient temperature: + 5 °C to + 40 °C
• Compatibility: Compatible with LINAK control boxes . Please contact LINAK
• Approvals: IEC 60601-1, ANSI/AAMI ES60601-1 and CAN/CSA-22 .2 No 60601-1
