0730-9001 Revision C2
CAUTION: This barrier is made of heavy steel components.
Ensure all personnel are cleared of area during operation.
1.1.3 Receiver Stanchion
The receiver stanchion accepts the barrier beam as it lowers and provides the structure
that transfers the crash impact energy to the surrounding ground. It is also engineered
using a “H” frame structure to assure strength and rigidity. The receiver stanchion is cast
in place in a subterranean concrete pour and has elevation grade locators to aid the
installation. The installation requires no above-grade concrete.
1.1.4 Options
The Model 730 vehicle barrier is available with a broad array of options and field
installed kits. Consult your ordering documentation to determine whether your system
has the optional equipment.
A traffic control gate arm to warn the vehicle operator. This arm is positioned
in front of the gate and does not rise until the gate is fully open, and it closes
before the gate starts to close.
Red/amber traffic lights. The light remains red if the gate is in any position
except fully open.
Infrared safety beams to detect pedestrian traffic or as an additional vehicle
sensing device.
2 OPERATION
2.1 Introduction
The barrier is moved to the up position with a single, center mounted, cylinder. The
cylinder is single acting to reduce wear on the hydraulic system. The HPU pulls the
beam barrier up and gravity pushes the beam to the lowered position.
2.2 First Time Operation
1.
Turn on the power at the master power switch located on the control circuit box.
Have someone remain at the power switch during the initial operation in case
there is a malfunction and the unit must be shut down.
2.
Working from the control panel, raise the gate arm. (The procedure for doing this
will vary depending on the design of your particular control panel.)
3.
Carefully observe the gate and make sure it is operating correctly. To achieve
proper arm travel, the hydraulic cylinder can be adjusted.
4.
The arm will stop when it contacts the limit switch or if the control unit times out.
The gate arm motion may not be smooth for the first several operations due to air
in the hydraulic lines.
