7. ADJUSTMENTS

7.1. ADJUSTING THE ANALOGUE POSITION SENSOR

The analogue sensor makes it possible to manage the opening and closing movements of the arm.
Due to its design, this type of sensor allows a much finer management of the arm movements, allowing precise accelerations
and decelerations. It also makes it possible to know the exact position of the arm at all times.
By convention, the cam is closest to the sensor when the arm is in horizontal position.
(*) If the LED is blinking, there is no longer a connection with the cam.

7.1.1. CALIBRATION OF THE ANALOGUE SENSOR

THE BARRIER WILL START MOVING TO DEFINE THE HIGH AND LOW POSITIONS!
1. Position the barrier arm in its closed position.
2. Disconnect the RJ45 connector from the AS1620 variable frequency drive to prevent the barrier from moving.
3. Adjust the analogue sensor, it must be positioned 3 mm from the cam (if the web interface is used, go to the 'Visualisation',
tab, look at the value in the 'Angular Position Sensor' box and adjust the analogue sensor until the value displayed is 2000
(± 100)).
4. Connect the RJ45 connector of the variable frequency drive to the control logic.
5. Follow the procedure for calibrating the analogue sensor.
For further information on the following steps, refer to the AS1620 control logic technical manual.
