When you receive your Barrier System, complete the
following steps.
Before you remove the barrier beam or cabinet from its
shipping carton, inspect the carton for damage. As you
unpack the carton, insure that all the parts listed below for
your system are included and are undamaged.
Inspect the parts for damage. Notify the carrier immediately
if you note any damage because the carrier must witness the
damage before you can file a claim.
The U.L. listed Model 620 or 640 Barrier gate system
includes a barrier beam and a cabinet housing the hydraulic
operator and control panel.
The main differences between the 620 and the 640 Barrier
systems are in the length of the barrier beam and in the
speed of operation. The 620 system controls beams that are
6-1/2 to 13 ft (2 to 4.5 m) in length and offers extremely
fast opening and closing times. The 620 is ideal for single-
lane vehicular traffic in moderate to heavy traffic. The 620
Barrier can also be articulated (jointed) for use with low
overhead clearances or skirted to prevent vehicles from
passing beneath the beam.
The 640 Barrier system is for barrier beams that are 13 to
23 ft (4 to 7 m) long and is suitable for wide entrances and
heavy-duty applications. The 640 Barrier can also be skirted
(Aluminum Beams Only).
The barrier beam is attached to a heavy-duty, lockable metal
cabinet bolted to a cement foundation. Inside the cabinet
are the operator and the control panel. Important metal
parts of the barrier unit have been powder coated to resist
the effects of rust and smog.
The motor housing holds the oil that drives the pistons and
helps to cool the motor. The temperature of the oil is
monitored, and in high oil temperatures a cooling fan
automatically turns on for further cooling.
The hydraulic motor of either the 620 or 640 operator
drives two single-acting pistons. Both are attached to the
rocker arm, and the rocker arm rotates the barrier beam. A
compression spring attached to one piston serves to
counterbalance the beam, and an adjustable braking feature
guarantees smooth movement of the beam through its
travel and prevents damage to the beam and cabinet from
abrupt stopping.
Some notable features enhance the reliable and safe
operation of the 620 or 640 Barrier. First, a hydraulic
locking device holds the beam in both the opened and

closed positions. Second, the metal cabinet that
houses the operator can be opened only with a key.
Third, the barrier includes a Manual Release function
to disengage the beam from its hydraulic operation
so that you can raise or lower the beam by hand.
Fourth, two adjustable hydraulic valves precisely
control the force of the beam in the opening and
closing directions.
An optional solenoid
automatically disengaging the hydraulic system in the
event of power failures.
Both the 620 and 640 Barriers are supplied with the
FAAC 625 BLD Control Panel. The control panel allows
you to select the following:
•
Logical mode of operation
•
Braking time of the beam
•
Pause time between opening and closing
The control panel also provides terminal connections
for a number of other reversing and gate system
accessories.
Furthermore, the control panel provides a number of
light-emitting diodes (LEDs) and a digital display for
easily diagnosing any operational problems.
