14. LA43 IC (MEDLINE

CARELINE

)

The LA43 Intelligent Control (IC) enables a simple system consisting of 1 or 2

actuators, a Switch Mode Power Supply and a hand control or a footswitch.

The system is for example an advantage when there is no space for a control box.

Usage:

Duty cycle: 10%, 2 minutes continuous use followed by 18 minutes not in use

Usage temperature: + 5º C to + 40º C

Storage temperature: -10º C to + 50º C

Compatibility: SMPS30

Approvals: IEC60601-1:2005 3

edition,

ANSI / AAMI ES60601-1:2005 3

edition pending

Recommendations:

• The actuator is not suitable for outdoor applications

• 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.

• If there is a risk of “pull forces” in the application, the actuator must be equipped with electrical spline to avoid damage in pull.

• If the actuator is operated without load (e.g. loose on a table) the electrical spline can activate and the actuator cannot run in an inwards direction.

Push the back ﬁxture and the actuator can be operated again.

• Connection bolts must be dimensioned so that they have the necessary strength 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. It is also for this reason that the actuator should not be used as a handle,

e.g pulling a patient hoist sideways.

• The actuator must not be subject to off centre loading, as this can damage 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 actutor and in the worst case cause damage to the actuator.

• The actuator must not be used in pull applications, as this can cause collapse.

• Only use the actuator within the speciﬁed working limits.

• It is recommended that the actuator is serviced according to the relevant national norms for the applications in which the actuator is used.

• Connection bolts and brackets are to be inspected in connection with service, and must be replaced if there are signs of wear.

• The safety function: Electrical Spline, should be checked in connection with service.

The function is checked by applying a straight pull, of max. 100 N, to the back ﬁxture. The actuator must not be able to run in an inward direction.

Hereafter press the back ﬁxture against the housing and the actuator can run in an inward direction.

• The actuator should be cleaned regularly, in order to maintain a good hygiene.

• The application must be tested for correct functionality before putting it back into operation.

• Do not step or kick on the actuator as it may damage the housing or the motor.

Warnings:

It is not allowed to use tools to adjust the installation dimension of the LA43 actuator as there is a risk that the inner tube may be

unscrewed.

Safety concept:

The user is a part of the safety concept. A light on the SMPS30 is green when a button on the handset is not activated. When a switch is activated the

light changes to orange. Orange indicates that power request is on.

When the light is orange and a button is not activated there is a fault on the system. And the user must call for service.
