Fig. 1.94. Scheme of interchangeability of wheels

Each of 1 sensors which are built in the gate is assigned to any wheel, therefore, wheels it is impossible to interchange the position (fig. 1.94) at all.

Otherwise there will be a danger of obtaining incorrect information that can have serious consequences.

Correctly to establish wheels, pay attention to color of a ring 2 around each gate (clear them if they are covered with dust or dirt) (fig. 1.94):

– А: ring of yellow color;

– В: ring of black color;

– С: ring of red color;

– D: ring of green color.
