The main function of a mushroom is to stop the drive in the upper end limit
position of the EVB, when the top slat presses against the mushroom.
Make sure that during operation, none of the slats on the
application exerts radial force on the mushroom or on a
guide tube, if used.
If the adjustable extension is pulled out, this renders the
drive permanently unusable.
3.2. MUSHROOM
It is of course possible to set the upper end limit before the slats touch the
mushroom; this provides additional safety (see section 4.3 Installing
the drive).
The mushroom can therefore be used to set the upper end limit position.
In this case, there is no need for the installer to set it. One or two
mushroom extensions can be used between the mushroom and its cap
to adjust the end limit:
It is important to note that if the application has Z-shaped slats, the
upper end limit of the drive must be set. In this case, the mushroom is
used to ensure the safety of the application.
When it is being lowered, if the EVB starts to rise again before it
has reached its lower end limit, the drive will immediately stop
when the slats press against the mushroom.
