ATTENTION:
-
do not use single cables (with one single wire), ex. telephone cables, in order to avoid break-
downs of the line and false contacts;
-
do not re-use old pre-existing cables;
-
In case of long sections of cables (> 20 m) for N.O./N.C. controls (e.g. OPEN / CLOSE, STOP, PEDE-
STRIAN, etc.), in order to avoid gate malfunctions, it will be necessary to uncouple the various
controls using RELAYS or using our 750T-RELE device.
2. INTRODUCTION
The K124MA board has two working modes, selectable through the J6 jumper (see wiring diagram).
J6 Not jumped:
J6 Jumped:
Once the connection is achieved, in low-energy mode, press the PROG button briefly:
•
All the green LEDs must be on (each of them corresponds to a Normally Closed input). The go off
only when the controls to which they are associated are operated.
•
All the red LEDs must be off (each of them corresponds to a Normally Open input). The light up
only when the controls to which they are associated are operated.

standard mode, i.e. the control unit is powered all the time;
low consumption mode, at the end of each maneuver the board automatically switches
OFF itself and all the auxiliary devices connected. The board will automatically switch
ON again activating the OP/CL contact or pressing the remote (mode where power is
supplied by other energy sources, ex. batteries charged by a photovoltaic panel). In
this way, the DL1 and DL2 LEDs flash every 4 seconds.
Description
Board supply input 18 V AC – Powered by the toroidal transformer housed
and protected by a fuse (F 6,3A) on the 230 V AC power supply.
For low power connection:
First connect the power supply given by the transformer and
then by the battery (terminals 1-2)
External power input (ex. Photovoltaic system 12V DC or battery 12V DC).
Notice: battery charger board not integrated.
N.O. input for PEDESTRIAN button - Controls prtial opening and closing
(1/3 of the complete journey) and it is subject to the setting of DIP SW 2
and 4.
(3= PED - 6= COM)
OPEN/CLOSE button N.O. input – Controls the opening and closing of the
automation and is regulated based on the function of dip-switches 2 and
4. (4= O/C - 6= COM)
