5.2 Function
The barrier consists of a barrier housing with drive system and a
barrier boom.
The drive system consists of an electric motor, control unit, and the
lever system. The lever system locks the barrier boom in both end
positions. In case of power outage, the barrier boom can easily be
moved by hand. Integrated balancing springs in the lever system
balance out the boom 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 boom and thus serve the control unit to
control the best acceleration and deceleration.
For the series "Access" and "Parking", the angled barrier boom
"VarioBoom" is used, this barrier boom enables driving through
even at an opening of only 35°.
Optionally, the barrier boom is available with a Vario flange with
boom cut-off option (FLVB02). If a vehicle drives against the barrier
boom, the barrier boom is pushed from the clamp. The barrier
boom 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.
