tau K124MA - Obstacle Detection

22
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 ashes in various colours:
Key:
led always on; led ashing;
Always on (green):
main voltage present;
1 ash every 4 seconds (green):
no main voltage; power supply through battery/photovoltaic
panel
CheckthemainvoltageandthefuseF2
LED - DL2
The DL2 LED indicates mistakes in the board logic with a series of pre-set ashes in dierent colours:
Attention: certain warnings/errors are signaled in sync with a series of ashes of the ashing light.
Key:
led always on; led ashing; error signaled by the ashing light;
