• The safety option manual lowering makes it possible to turn the inner tube down by hand in emergency cases or if electrical power is not available .

• Activation of a quick release can lead to a risk of squeezing body parts . Installation of a damper may reduce this risk .

• A quick release can accidentally be activated during mounting or maintenance . To avoid this, operators must be warned before service/mounting .

• 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 .

• 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 .

• If the actuator does not work as intended, there is a risk of injury . Therefore, the actuator must immediately be sent to the nearest authorised LINAK

workshop for service .

• The actuator is not designed for repeated dynamic push-to-pull movement .

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 the worst case cause damage to the actuator .

• 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 .

• LA40 with mechanical endstop - a first failure safe option:

In many applications customers have approvals in accordance with EN 60601-1 . The typical applications are beds, massage couches etc . The norm

EN 60601-1 states that the application must be first failure safe . The manufacturer has the responsibility of carrying out a risk analysis in order to

check this . If a risk is identified, the application manufacturer must ensure that this risk is eliminated . A switch cannot be first failure safe .

)

The LA40 is a low noise and powerful actuator which is available in a 1,500 N,

4,000 N, 6,000 N and an 8,000 N version .

With the LA40, LINAK offers a new durable actuator with high speed/high

performance and mechanical endstop for first failure safety making it the right

choice for the future market . The LA40 versions are rated up to IPX6 Washable

DURA

, except for the LA40 PL version which is rated up to IPX6 .

The LA40 8,000 N is available in three versions:

- Standard

- High Performance (HP)
