4.1 PRELIMINARY CHECKS

For correct operation of the automation system, make sure:
• all the accessories are suitably sized and properly maintained.
• all the operating limits of the product can be complied with.
• the minimum and maximum clearances shown in FIG. 1A, FIG. 1B
and FIG. 1C are complied with.
• all material used is in perfect condition and fit for purpose.
• the selected installation site is compatible with the overall dimensions
of the product.
• there are no hindrances that could obstruct the opening and closing
movements of the barrier arm.
• the footing of the barrier system is able to provide stable anchorage
of the unit.
• the space around the barrier system is sufficient to allow easy and
safe execution of manual barrier operations.
• all devices to be installed are in a protected location so as to minimize
the risk of accidental impact.
• If necessary, create a pedestrian entrance well clear of the operating
range of the barrier arm.

LIMIT 500/600/800:
• Before installing the operator check that its specifications are within the
operating limits shown in the chapter "Product Technical Specifications"

4.3 PREPARATORY WORK FOR INSTALLATION

• Assemble counterplate and anchor bolts (FIG. 2A for LIMIT 500, FIG. 2B
for LIMIT 600-800)
• Embed counterplate and anchor bolts in concrete (FIG. 3A)
• In the case of an existing concrete footing drill 4 holes for the screw
anchors as shown in FIG. 3B.

4.4 INSTALLING THE LIMIT BARRIER SYSTEM

4.4.1 INSTALLATION:
• Remove the front cover using the supplied key (FIG. 4)
• Place the pedestal on the counterplate, routing the power and
accessories cables through the cable inlet hole. Secure the pedestal
with the nuts and washers supplied (FIG. 5)
Arm assembly:
• To create an arm of 7 or 8 metres long, assemble 2 sections (available
in 3-4-5 metre lengths)
• When using a round arm (LIMIT 800) use the specific joint as shown in
FIG. 6A
• When using a rectangular section arm (LIMIT 500 and 600) use the
specific joint as shown in FIG. 6B
• Where required, attach the adhesive LED strip in the channel over the
full length of the arm (FIG. 7A)
• Insert the impact protection strip in the specific guides, stopping at a
distance of 175 mm from the opposite end FIG. 7B. The rubber impact
protection strip cannot be fitted on round section arms.
• Secure the end cap to one end of the arm, as shown in FIG. 8A for
LIMIT 500/600 with impact protection strip, FIG. 8B for LIMIT 500/600
without impact protection strip, and FIG. 8C for LIMIT 800. If the arm is
composed of several parts, the end cap must be fitted to the shortest
section.
Installing the arm:
• Release the operator as described in heading 4.4.3
• Fix the arm support to the protruding pivot at the rear of the frame and
ensure it is in the "arm horizontal" position (FIG. 9A) and that the internal
mechanism is in the position shown in FIG. 9C. Smear threadlocker on
the 4 central screws as shown in FIG. 9A and FIG. 9B
• When using a round arm, use the specific support as shown in FIG. 9B
• Make sure the arm is fully inserted into the support.
• Close the support by fitting the cover (FIG. 9A – FIG. 9B).
Assembly of the linkages:
• In the case of LIMIT 600 and LIMIT 800 couple rocker arm A to the drive
shaft via linkages B and C (FIG.10A) appropriately assembled for RH
units (FIG.11A) and LH units (FIG.11B) with the addition of threadlockers
(FIG.10A)
• In the case of LIMIT 500 the linkages are not present.
Fitting the springs:
• If the barrier system is locked, to release it proceed as illustrated in
heading 4.4.3
• Bring the arm to the vertical position (FIG. 12)
• Secure the spring (single or double) at the top and at the bottom as
shown in figures 13A, 13B and 13C
• When installed, make sure the arm is counterbalanced by the spring as
shown in figures 14A and 14B
• Choose the appropriate spring by referring to the following table
