SSEMBLING THE "RAPID PARK"
After you have cemented in the base plate where you want it, mount
RAPID PARK using the nuts provided and a no. 19 hexagonal wrench.
Then assemble the barrier arm in three phases as follows:
1 - Following components must be assembled before final installation:
rod and rod support, by means of the four allen screws as supplied,
and a 6mm allen key (for better identification see figures 3 - 10).
2 - The barrier is supplied with the balancing spring decompressed so
the barrier arm and its attachment must be inserted, in vertical
position, into the barrier arm fixing attachment.
3 - Install the rod and fasten with the allen screw as supplied, by means
of a 8mm allen key, and insert the caps.
The gear unit is irreversible so no kind of external locking device is
necessary to keep the barrier in securely closed position.

ALANCING SPRINGS SETTING
Normally the barrier is supplied to you with the balancing spring already
set.
If a weight is added to the boom (e.g. pneumatic or photocell strips), the
boom has to be rebalanced (Fig. 4).
If the boom tends to accelerate when it is lowered, adjust the balancing
spring as follows:
1 - With the gearmotor engaged, raise the boom under electrical power
until vertical.
2 - After disconnecting power supply, screw down the ring nut in a
clockwise direction so as to increase the compression of the springs
during the lowering movement.
To check correct boom balance, disengage the gearmotor and move the
boom by hand. The boom should tend to rise a little.

IMIT SWITCH SETTING
Normally the barrier is supplied to you with the limit switches already set
to allow optimum barrier movement.
If the base plate has not been cemented in on a level plane, the boom
might be not perfectly horizontal or vertical, with the result that the
aesthetic appearance of the installation is poor.
To avoid this, it is possible to alter the trajectory of the boom by adjusting
the mechanical and electrical limit switches (Pic. 5):
1 - With the barrier up, use a no. 19 hexagonal wrench to loosen the
retaining nuts (A) and a no. 8 Allen key to loosen or tighten the
countersunk screws (B) for setting the mechanical limit stops so as
to delimit the arc described by the barrier boom.
2 - Having done this, the limit switches now have to be set so as to
determine the electrical operation of the motor for the new trajectory
described by the boom. To do this, you must use a no. 3 Allen key to
release the two limit switch adjusting cams (C). Once the boom is
positioned in accordance with the mechanical stop, you need only to
rotate the cam involved so as to trip the limit switch.
3 - Once this is achieved, retighten the cam.
NB: If during operation there is no slow down movement, please note
that this cannot be necessarily caused by the control panel failure.
In fact, the absence of the slow down movement can be caused by
the incorrect adjustment of the electrical limit switch cams.
Especially when the barrier is opening (or closing) and the slow
down electrical limit switch is pressed, if the other slow down limit
switch has not been released, the slow down movement does not
operate. In order to eliminate this problem it is enough to increase
the distance between the two cams.
