Proper use
Linear units are used for linear movement of loads mounted firmly on the shaft slots/trolley in an
environment where there is no risk of explosion under the defined operating and environmental
conditions for this product. The device can be installed in any position (horizontally, vertically or at an
angle).
The toothed belt drives in linear units do not generally lock automatically.
With vertical installation, the linear unit's motor (in this case, the weight of the shaft slot/trolley and the
load to be moved must be calculated) should have a brake, which locks the movable shaft slots of the
linear axis to prevent crashing/pancaking when the power is turned off. If no brake (e.g. magnetic
brake) is fitted to the motor, another (electro-)mechanical brake must be used, e.g. on the toothed belt
wheel.
The linear units referred to in these assembly instructions are considered partly completed machines
(see article 2g of MRL 2006/42/EG). An partly completed machine is also defined here as follows
(quote):
"An partly completed machine is a unit which almost forms a machine, but cannot fulfil any given
function independently".
A drive system represents a partly completed machine.
A partly completed machine is only intended to be installed in other machines or in other partly
completed machines or equipment or be combined with it to form a machine together with it as defined
in this directive.“
The linear unit LEZ 1
– LEZ 2 – LEZ 3 – LEZ 9 is intended for installation in a machine or in other
partly completed machines.
The product is not intended for use outside and for transporting people, nor in food handling areas and
in clean rooms.
Any use other than as described above is improper and can lead to personal injury and damage to
property.
