Recommendations
• To avoid unintended activation of actuators if hand control cables short-circuit, LINAK recommends to use an OpenBus
TM
system (CO71).
• If there is a risk that the system is overloaded and therefore shuts down thermally, LINAK recommends to use quick release actuators.
These will allow functions to be lowered manually in case of a CO71 malfunction due to misuse/abuse.
• If the customer has other essential performance than “no unintended movement”, he must consider this in his own risk analysis.
LINAK disclaims any liability.
• If the actuator or the control cable is removed from the control box, the cable lock must be applied. To ensure movement in this case,
LINAK recommends to use quick release actuators in the application.
• To avoid cables from being damaged by pulling, LINAK recommends to make safe cabling. If movement is an essential performance,
LINAK recommends to apply quick release actuators, for example, to ensure movement.
• To avoid thermal protection from being activated, do not exceed load specifications. If movement is an essential performance,
LINAK recommends to apply quick release actuators, for example, to ensure movement.
• Sales must request a review of the products according to current cut-off limits.
Motor cable
Always use 6-wire cables.
Please note that angled motor cable plugs are required for connection to the control box.
Warnings
• Use EPR or ensure that the user takes care not to squeeze the mains cable.
• Always check correct assembly after mounting and service to ensure that the cable lock is mounted.
(Connectors are usually removed during cleaning)
• Always use approved chemicals with the housing as the plastic may show corrosion caused by some chemicals. As a result water may
accumulate/gather in housing.
• Take special precautions concerning 3
rd
party interfacing. Please contact LINAK for further information.
• Make a review of all product specifications before system set-up if the current cut-off limit is higher than the maximum allowed current
cut-off for the actuator.
• To avoid cable interruption and actuator defects make a proper cable installation and inspect regularly for wear and damage.
Defective parts must be replaced.
• After service inspection, the application must be tested for correct functionality before it is put into operation to avoid actuator plugs
being mixed during service. Operators must not be inside entrapment area.
• To avoid electrical failure or system disturbance inspect regularly for wear and damage. Defective parts must be replaced.
• Make a proper cable installation to avoid short-circuit cables for hand control/controls.
Regular inspection must be made for wear and damage. Defective parts must be replaced.
• Loss of mains: If the power supply is switched off for a short time (between 1 and approx. 1.5 seconds), the control box will only start up again if
a key is pressed. This is only relevant for OpenBus
TM
systems that run continually
• Do not mount the actuator with the spindle facing downwards to avoid that the actuator slips off the bracket with mounted control box.
The bracket can come loose when exposed to shock or hard vibration, for instance when passing doorsteps.
Regular inspection must be made to ensure proper fixation of control box and bracket on actuator.
