This is a magnetic sensor. Positioned next to a magnet that will rotate at the same time as the motor shaft, it will pick up the magnetic field emitted by this magnet and retransmit it as an electrical signal to the board.

In this way, it knows whether or not the motor is running, at what speed, and where the gate is in its travel.

Hall effect boards are positioned at the top of the electric motors. They are wired with 3 white wires, or 3 black wires.

The Hall effect card is connected with 3 wires.

• One positive (+12V)
• One negative (GND)
• One signal output (HALL)

To spot the positive :

• On the version with black wires, this is the only wire with white markings on it.
• On the version with white wires, this is the wire with the cross marks.

The middle wire is the negative (GND).

The wire opposite the positive is the HALL.

So cross the HALL and GND to connection on the board.

As mentioned in the introduction, this element tells the electronic board whether the motor is running or not. In the event of a Hall effect card fault, the electronic board will react as if the motor were not running, and will indicate corresponding errors.

Typically, during self-learning, you’ll get the L3 error message after a short motor run (the motor has reached its opening stop in less than 3s).

Before validating this fault, check that the magnet positioned next to it is firmly attached to the motor shaft and rotates with it.

Also check that all red LEDs on the board light up after a short press on the SET key.

Sometimes it can short-circuit, blocking the board’s electrical start-up.

If you notice that your electronic board no longer has any warning lights, or that they are only dimly lit, disconnect the terminal block motor from the board, and check that it restarts properly.

First of all, check that each cable makes good contact with the terminal block slots, and that the wires are tightly clamped by the slots’ jaws.
