Adjusting Barrier Arm Length 3.4
The operating parameters are adjusted before delivery according to the required barrier arm
length. When the Barrier is delivered on site, you need to adjust the mechanical balance of the
Barrier again to keep the barrier arm in horizontal state.
Determine whether to shorten the barrier arm as required on site, and then install the Step 1
barrier arm on the Barrier. See "3.3 Installing Barrier Arm."
In power-off state, select the right number of springs and adjust the tightness of each Step 2
spring to keep the barrier arm suspended at about 40°–45°.
