Obstacle Detection - tau K123M Installationsanleitung

FLASHING LIGHT (18 Vdc - max. 20W)
Besides signalling the opening and closing of the gate, at the end of the opening or closing manoeuvre
it also signals errors with a series of pre-defined flashes, which last for max 30 seconds.
• steady light:
1 flash:
•
Check the mains power supply, charge the battery, replace the battery.
2 flashes:
•
Disable phototest (dip-switch 6 OFF)
3 flashes:
•
Check the thermal-magnetic circuit breaker (upstream from system), check the hour counter.
4 flashes:
•
Gearmotor has exceeded absorption limits, check for obstacles along the path of the gate.
5 flashes:
•
Check wiring, check encoder through TEST-ENCODER (optional).
6 flashes:
•
Make sure there are no obstacles across the path of the gate.
7 flashes:
•
Execute memorization procedure.
8 flashes:
•
Reset manoeuvre counter
N.B.: The microprocessor version installed in your control panel is not enabled for manoeuvre
counting.
Multiple errors are signalled by a 2-second pause between signals. Errors continue to be signalled
until a complete opening and closing manoeuvre is executed.
GATE OPEN WARNING LIGHT (18 Vdc - max. 3W)
The gate open warning light flashes during the opening or closing manoeuvre in synchrony with the
flashing light, then shows a steady light when the gate has opened completely. Once the closing
manoeuvre has been completed this light goes off .
In addition, the gate open warning light signals the following:
• programming phase (when dip-switch 8 is set to ON);
it flashes in sync with the flashing light;
• mains power supply restored
it emits a series of flashes for approx. 2 seconds;
• presence of obstacles across the path of the gate after 5 attempts to close have failed;
it flashes in sync with the flashing light.
BATTERY CHARGER BOARD (INTEGRATED)
If the battery is connected the automation will operate in any case if there is no mains power supply.
If the voltage drops below 11.3 Vdc, the automation ceases to operate (the control unit remains fed);
whereas, when the voltage drops below 10.2 Vdc, the card completely disconnects the battery (the
control panel is no longer fed)

OBSTACLE DETECTION

If the obstacle detection function (which can be set through trimmer FR) is activated during an
opening manoeuvre, 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.
