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 K126MA board has two working modes, selectable through the J6 jumper (see wiring diagram).
J6 Jumped:
J6 Not 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.

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).
