4.6 ACCESSORIES ON THE ARM

!
The accessories on the arm must be considered when
choosing the balancer spring (single or double).
The accessories on the arm must be installed before
balancing the arm. If the accessories are added or
removed later it may be necessary to change the
spring. After any modification to the arm, it is
necessary to balance it again.
The spring appropriate for the configuration and
length of the arm is defined in the balancing tables
(see  2).

4.7 BALANCING THE ARM

This operation requires the barrier to be released.

there is no electrical power.
- Keep away from the moving elements inside the
box and from the coil spires.
- Do not leave the arm vertical when the barrier
is unlocked.
- Make sure the arm is properly balanced before
putting the barrier in operation to avoid extra stress
on the spring that could reduce its lifespan.
