13. The automatic barrier will be in good opening condition, when the
beam / boom is in the condition shown in the image below.
Note:
It is not necessary to balance the beam again, as it leaves the
factory balanced. However, if necessary, follow the instructions below.
BALANCING THE BEAM AND CHECKING THE
CHAIN
1. Remove the gearmotor from the cubicle, leaving the chain free.
Check if the beam remains at a position around 45°. Otherwise, the
adjustment will be made through the spring bolt, either loosening or
tightening it until the ideal adjustment is reached.
2. Once this is done, place the gearmotor and the chain again. Check
if it is properly stretched and ready for operation. With your thumb,
apply an even pressure on the chain. If it does not bend, it is properly
stretched. If the chain is loose, adjust it using the belt tensioning
bolts, using a wrench according to the respective nut.
ADJUSTING THE MAGNET BARS
With the beam properly balanced, and with its opening and closing
'mechanical stoppers' adjusted, check if it is necessary to adjust the
magnet bars.
1. Keep the beam in the 'open' position (90°).
2.
Adjust the magnet bar so that the last magnet is in front of the Sensor
Hall (Encoder) and tighten the fixing bolts.
Note:
Perform the same procedure with the beam in the 'closed' position
(0°).
The automatic barrier is ready to operate. Turn on the circuit breaker,
press the '+' button on the electronic control board and the barrier will
function.
