Attention: the rod is not secured nor balanced.
- Assemble any accessories (sensitive rubber profi le, apron,
container support, etc).
Attention: Due to its high speed, the UP2EL UP2EH model can-
not be fi tted with accessories.
3.4 Spring balancing
Check for suitable springs as it is shown in table 1
N.B.: (Only for UP4E-UP4EH) The barriers come with a sepa-
rate spring (type UP4M) for a net span of between 2500 to
3500 mm.
If the high, and therefore heavier, sensitive edge is used, refer
to UPGR apron column for spring choice.
If the UPAM mobile support or the UPSN articulated joint are
added, spring choice does not change.
Tighten springs by means of the proper tie rod [20] and with
boom arm in a vertical position.
Unlock motor.
After spring tightening, place boom arm at approximately 45° (all
accessories included) and make sure it is well fi xed.
Make also sure that, in closing and opening fi nal positions, the
boom arm remains fi rm.
Attention: Never use the motor force to support the weight of
the arm. Always use the balancing spring.
3.5 Limit switch adjustment
- Only UP2EH. The barrier is default set with an opening
of approximately 90°. If the opening/closing position is to
be changed, adjust the internal mechanical lock [16] to
enable a new stop at the rod.
- (Fig. 4, part. 16) Adjusting the rod in the horizontal posi-
tion: make the fi ne adjustment with the internal mechanical
lock.
- (Fig. 7) Adjust the opening limit switch in order to stop the
motor 2-3 mm before the lock (*).
- Position the rod vertically and lock (see operating instruc-
tion).
- Adjust the lock for opening 2-3° before the 90° opening
(*).
- (Fig. 7) Adjust the opening limit switch in order to stop the
motor 2-3 mm before the lock (*).
(*) with use the barrier recovers the clearance.
ATTENTION: The door of the barrier is impact resistant; it must
always be mounted on the container during the operation of
the barrier.
