Obstacle Detection; Diagnostics Led - tau K127MA Notice D'installation

- During the various stages of the operation, if the sensor is activated saving is stopped. To
restart the procedure from the beginning (with the DL8 yellow LED flashing), use the AP/
CH control, the remote control (if programmed) or press the PROG button briefly.
Please remember that an obstacle during saving is interpreted as a mechanical limit stop
(the system does not start any safety operation, it just stops the motors).
Make sure you don't stand near the automation during saving.
K127MA CHARACTERISTICS
MASTER/SLAVE
The Master/Slave function - useful to manage two opposing sliding gates - can be activated through
the TAUPROG handheld programmer (optional).
TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening/closing of the automation can be controlled by means of a timer that has a free N.O.
output contact (relay). The timer must be connected to terminals 4 - 6 (OPEN/CLOSE button) and can
be programmed so that, at the desired opening time, the relay contact closes until the desired closing
time (when the timer's relay contact opens, enabling the automatic closing of the gate).
Note: the automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
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 open-
ing 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.
