Technical Characteristics - tau K125M Notice D'installation

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. TESTING
When you have completed the connection:
• 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 LS 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. Except for the DL3 diagnostics
led which must always be on.

Description
board supply input 13,5 Vac – Powered by the toroidal transformer housed
in the T-ONE5B motor and protected by a fuse
supply.
SENSITIVE EDGE input (resistive sensitive edge or fixed safety edge); Works only
when the gate is opening; temporarily stops the gate and partially closes it by about
20 cm in order to allow the obstacle to be removed. 1= SENSITIVE EDGE, 3= COMMON.
If a resistive sensitive edge is connected, set dip-switch no. 9 to ON;
If a fixed safety edge with NC contact is connected, set dip-switch no. 9 to OFF.
input for PHOTOCELLS OR SAFETY DEVICES active during closure (Normally
Closed contact); They stop the gate during closing and totally reopen it; they
temporarily stop the gate during opening in order to allow the obstacle to
be removed (if dip switch n° 3 set to ON). If there is more than one safety
device, connect all the NC contacts IN SERIES. 2= PHOTOCELL.
The photocell transmitter must always be supplied by terminals no.
10 - 11, since the safety system test (phototest) is carried out on it. To
override the testing of the safety system, or when the photocells are
not used, set dip-switch no. 6 to OFF. If the phototest is not successful,
the control unit will not operate.
