7 - BALANCING OF THE
BOOM
After having hooked the balance spring as
described in the chapter 5, it is necessary to
proceed to balance the boom.
1.
Unblock the automation
2.
Rotate the balance spring manually
in order to increase or to diminish the
traction. The boom must be stabilized at
45°.
3.
Fix the locking nut and block the motor
reducer.
m
ATTENTION: verify correct
operation of the balance spring
• with the boom positioned vertically,
the balance spring is not in tension
• with the boom positioned
horizontally, the balance spring is in
tension
8 - EMERGENCY LOCK
RELEASE
In case of power loss, bypassing the
motor manually can unblock the barrier
mechanically.
Insert the supplied key into the lock, make
a half turn clockwise and extract the
ratchet. Insert a 5mm Allen wrench into
its appropriate seat and make 1/4 turn
clockwise: now the boom is free and can be
manually operated.
To restore the automatic function, simply
rotate the Allen key to its original position,
insert the ratchet and rotate the key a half
turn counterclockwise.
