WARNING!
WARNING!
Danger of crushing at opened barrier housing
at the lever system!
The lever system in the barrier housing can cause
serious crushing injuries!
Therefore:
– Balancing springs in the lever system must only
be checked and adjusted by specialised
personnel.
– Balancing springs must only be checked and
adjusted with the power supply turned off
– Wear protective gloves if necessary.
The lever system has balancing springs that exactly balance the
barrier arm weight. These balancing springs are pre-set in the
factory. The precise setting must be performed after assembly of
the barrier arm and before commissioning.
The lever force is determined not only by the spring tension but
also by the number of springs used and the spring rate.
MAGNETIC uses two spring types. Depending on application case,
you will have to set the spring tension, remove the springs, use
additional springs or use springs with a different spring rate.
Also see page 84, chapter 8.13.2.
In the "Power behaviour" menu, you can set the barrier behaviour
in case of voltage failure.
See page 135, chapter 10.10.9. The
settings in this menu do not influence the settings of the balancing
springs.
