5.2 Function
The barrier consists of a barrier housing with drive system and a
barrier arm.
The drive system consists of an electric motor, control unit, and the
lever system. The lever system locks the barrier arm in both end
positions. In case of power outage, the barrier arm can easily be
moved by hand. Integrated balancing springs in the lever system
balance out the arm weight exactly. These balancing springs are
pre-set in the factory.
Sensors integrated in the motor supply exact data on every correct
position of the barrier arm and thus serve the control unit to control
the best acceleration and deceleration.
For the series "Access" and "Parking", the angled barrier arm
"VarioBoom" is used, this barrier arm enables driving through even
at an opening of only 35°.
Optionally, the barrier arm is available with a Vario flange with arm
cut-off option (FLVB02). If a vehicle drives against the barrier arm,
the barrier boom is pushed from the clamp. The barrier arm can be
mounted again.
Safety facilities like induction loops or safety light barriers must be
installed on site in all cases. The safety installations must ensure
that the barrier closes only after the vehicle has passed through.
Safety installations, such as induction loops can be purchased
from MAGNETIC. The safety light barriers must be MAGNETIC
ones.
