Linak TECHLINE LA37 User Manual page 7

During operation, please be aware of the following:
• Listen for unusual sounds and watch out for uneven running. Stop the actuator immediately if anything
unusual is observed.
• Do not sideload the actuator.
• Only use the actuator within the specified working limits.
• Do not step or kick on the actuator.
When the equipment is not in use:
• Switch off the mains supply in order to prevent unintentional operation.
• Check regularly for extraordinary wear.
Classification
The equipment is not suitable for use in the presence of a flammable anaesthetic mixture with air or with oxygen
or nitrous oxide.
Warnings
• Do not sideload the actuator.
• When mounting the actuator in the application ensure that the bolts can withstand the wear and that they
are secured safely.
• If irregularities are observed, the actuator must be replaced.
• For actuators with a stroke length below 130mm, the extended position of the mechanical endstop will
always be at 130mm. That means, if an actuator has a stroke of 80mm and the endstop switch in outwards
direction fails, the actuator will travel additional 50mm before reaching mechanical endstop.
Recommendations
• Do not place load on the actuator housing and do prevent impact or blows, or any other form of stress to
the housing.
• Ensure that the cable cover is mounted correctly. Use 3.5 Nm torque.
• Ensure that the duty cycle and the usage temperatures for LA37 actuators are respected.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.
• Furthermore, it will be good practice to ensure that the actuator is fully retracted in the "normal" position.
The reason is that there will be a vacuum inside the actuator if it is extended which over time can lead to
water entering the actuator.
• If the actuator (without integrated controller) is mounted in an application where a mechanical stop prevents
the endstop switches in the actuator from being activated, the actuator must be equipped with an electrical
safety device (current monitoring) or external limit switch.
