5.
If necessary, adjust the limit switch so the switch activates, the gate arm stops at
the correct position, and the hydraulic pumping unit shuts off when the arm is in
the fully up position.
6.
Make sure the gate arm stops smoothly in the receiver post and does not oscillate,
contact hard, or make excessive noise.
2.3 Control
The 730 barrier is controlled by the flow of hydraulic fluid under pressure from the HPU
to the cylinder. All control components are connected to the HPU.
2.4 Operating Time
The operating time for the 730 barrier is field adjustable at the HPU by varying the
hydraulic fluid flow from the HPU as required. Normal operation cycles range from 15-
20 seconds for both up and down. These times may be adjusted to meet application
requirements. Please consult a B&B ARMR technical support person if required.
