4.3 Using the leaf-opening angle as criteria to make sure all criteria in Figure 17 can be met
FIGURE 17
1) “C” value is 139mm
2) “D” can be measured from the gate easily
3) “A” = “C” + “D”
4) The value of “B” can be calculated from the value of “A” and the leaves opening angle. Ex. If
“A” =160mm with the leaves opening angle of 100 degrees, then the value of “B” is approximate
190mm
NOTE: Please make sure “ B” and “A” are similar or the same in value that the leaves can be
operated smoothly . Also to reduce the burden of the motor.
