Obstacle Detection - tau K124MA Installation Manual

OBSTACLE DETECTION

If the obstacle detection function (adjustable through FR trimmer) is activated during an opening ma-
noeuvre, the gate closes approx. 20 cm., if it is activated during a closing manoeuvre, the gate opens
all the way .
WARNING: the control panel logics may interpret mechanical friction as an obstacle.
8. LED DI DIAGNOSI
LED - DL1
Apart from highlighting the presence of the battery, LED DL1 displays any mistakes with a series of
pre-set flashes in various colours:
Key:
led always on;
Always on (green):
1 flash every 4 seconds (green):
LED - DL2
The DL2 LED indicates mistakes in the board logic with a series of pre-set flashes in different colours:
Attention: certain warnings/errors are signaled in sync with a series of flashes of the flashing light.

Memorization to be carried out of the variation in deceleration
The board recognizes the variation in position of the RALL trimmer and si-
gnals the memorization to be carried out in order to learn the new decelera-
tion. Press the PROG key. (see paragraph "RALL trimmer")

Disable phototest (dip-switch 6 OFF), check the operation of the photocells
and their connection;

obstacle for motor;
:
Make sure there are no obstacles across the path of the gate and that it slides
smoothly;
With an active automatic closing feature, after the intervention meant to de-
tect the obstacle, the automatic closing is deactivated. A command pulse is
required to carry out the closing;
no motor encoder signal;
:
Check wiring, check encoder by TEST-ENCODER (optional);
Check the correct flashing of led E1 *
