Balancing the barrier
Unlock
THE BARRIER MUST BE BALANCED FOR
PROPER OPERATION.
•
In order to complete the balancing, connect the
power supply and check operation: the barrier
should move smoothly, without jolts or jerks.
•
If it does not move smoothly, without any jolts or
jerks, reduce the tension of the spring using the
tensioning handle.
The barrier may not be balanced when moving
the handle; if this is the case, change the
anchoring orifice (from 1 to 2) or the balancing
spring. Repeat these steps until the barrier is
balanced and moves smoothly.
ULS6EC barriers have two springs and two
knobs for tensioning
.
Balancing is done by acting equally on the two
knobs, to ensure the tensioning of both springs is
approximately the same.
The tensioning handle is only accessible with
the arm in upright position.

LED Strip
If the LED strip is installed (AUL09 for 3 m Barriers;
AUL05 for 4.5 m barriers; AUL06 for 6 m barriers),
use the hole furthest from the arm to pass the
cable inside the barrier.
