1.13 Adjusting the Barrier Movement

When installing or maintaining a CR-25 barrier, setting the limit switches and connecting rod length properly can be confusing at times. The following instructions are intended to clarify this process. The steps can be broken into two sections, setting crank orientation, and setting barrier starting and stopping points.

SECTION 1: SETTING THE CRANK ORIENTATION AND ROTATION USING THE LIMIT SWITCHES

A standard CR-25 barrier operator with 90 degrees of travel is designed so that the barrier arm accelerates and decelerates smoothly as it pivots. This is achieved through the lengths of the two crank arms. In order to optimize this “sinusoidal” movement, the following steps should be followed when installing the operator.
