7. K128MA CHARACTERISTICS
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).
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:

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")
