The control unit automatically recognizes relay photocells connected to AUX1, AUX2, and AUX3 if the "Programming with relay photocells" function is activated.

To perform recognition:

  1. Simultaneously press and hold the [Open] and [Stop/Set] buttons.
  2. Release the buttons when the "L1" and "L2" LEDs blink rapidly (approx. 3 seconds).
  3. Wait for the control unit to complete the recognition process.
  4. The "Stop" LED will remain lit, while "L1" and "L2" will turn off. "L3" and "L4" may start blinking.

If AUX In 1-2-3 are used for relay photocells, leave unused inputs free.

4.7 Motor Type Selection (Hydraulic Motors Only)

This step is only necessary for hydraulic motors. It involves setting the "Pressure Maintenance" function to prevent accidental gate opening due to hydraulic circuit pressure loss.

4.8 Recognition of Mechanical Limit Stop Positions

After device recognition, the mechanical limit stop positions (maximum opening and closing) must be set. This can be done in three ways: automatic, manual, or mixed mode.

4.8.1 Automatic Recognition Mode

The control unit automatically recognizes the limit stops and calculates the gate leaf phasing and deceleration points.

  1. Simultaneously press and hold the [Stop/Set] and [Close ▼] buttons.
  2. Release the buttons when the "L3" and "L4" LEDs blink rapidly (approx. 3 seconds).
  3. Verify the automation performs the following maneuvers: M1 closing, M2 closing, M2 opening, M1 opening, M1 closing, M2 closing.
  4. If the first two maneuvers are opening instead of closing, stop the procedure, reverse the motor wires, and repeat automatic recognition.
  5. Upon successful completion of the closing maneuvers (e-f), the "L3" and "L4" LEDs will turn off.
  6. If photocells or a stop device are triggered during recognition, the procedure will interrupt, and the "L1" LED will blink. Repeat the automatic recognition procedure.

Note: Automatic recognition can be repeated at any time.

4.8.2 Manual Recognition Mode

This mode allows programming each position individually by moving the gate leaves to the desired points. The position to be programmed is indicated by the blinking of one of the "L1-L8" LEDs (refer to "Table 4").
