Limit switch adjustment


At the end of a closing or opening movement, the barrier arm stops by means of the limit switches (20:1)
and (20:2) actuated by the adjustable cams (20:3) and (20:4). To check if the position of these two cams is
correct, proceed with the following test, after you have made sure that the arm level is correctly adjusted
according to paragraph [4.7 Levelling the barrier arm]:
19:1
The positioning of the limit switch cams will be correct if, when the arm stops in horizontal or vertical position, the
motor stops and the crankshaft plate is flush (without pressure) with the corresponding abutment (19:1) or (19:2).
