Wejoin barriers are at the leading edge technologically. Ours were the first intelligent barriers with manually operable clutch units. In case of a power failure, just gently open the clutch unit to allow manual pole lifting. The microcomputer control is adopted for a smart limit unit, requiring no limit switch. When the pole rises to vertical it will automatically detect the signal and stop running. Our barriers utilize a special process to effect internal movement. The unique mechanical construction with electronic high technology allows for free movement of the pole.
Security:
1) Intelligent obstacle return unit: In case of any obstacle during the pole falling process, the pole will reverse
2) Intelligent infrared photocell unit prevents collisions: If the infrared signal is interrupted, the pole will reverse if falling
3) Two indicator lights can be connected (220V R&G):
A) Red light indicates pole movement
B) Green light indicates no pole movemen
