a The power supply and the fuse are related to the
purchased version.
b Different output values can be obtained on the board
supply terminals depending on the mains voltage
value. Before start-up always check if the output
voltage on the transformer secondary winding
is between 20 Vac and 26 Vac. Voltage must be
measured load free.

installed on leaf 1)

J8 MOT2 Motor 2 (leaf 2)
The service light control is active during the entire
gate opening or closing movement and for the
successive 90 seconds.
Leaf 1 means the leaf which opens first during the
opening operation.
3.3. Anti-crushing function
The electronic anti-crushing function is obtained by control-
ling the current consumption or the encoder of the motors
connected to the BRAIN 15 equipment.
If the gate detects an obstacle during the opening or closing
movement, the anti-crushing function activates and reverses
the sense of direction of the operator, thus increasing the
safety degree of the automated system.
3.4. Over pushing stroke
If you enable this function, at every OPEN pulse the leaf on which
the electric lock is installed starts its closing movement for a few
seconds. This facilitate release of the electric lock.
4. PROGRAMMING OF THE LOGIC
Repeatedly press the SW3 LOGIC push-button to select one
of the 7 programming logics available.
The selected logic is signaled by the LD7 LED:
The number of blinkings corresponds to the number of the
selected logic.
See paragraph 6.3.3.
5. PROGRAMMING THE SPEED
The function speed can be adjusted at any time by pressing
push-button SW2.
The selected logic is then displayed on LED LD8:
Led on = HIGH speed
Led off = LOW speed
