STOP button N.C. input – Stops the automation in any position, temporarily pre-
venting the automatic closure, if programmed. (5= STOP - 6= COM )
NOTE: A safety micro-switch is connected to the STOP push-button. In case
the STOP input remains open for more than 5 seconds, the operator will per-
form a cycle at a slow speed to reset the operating parameters to the values
originally saved (see "Restoring automatic operation"). The micro-switch
should be connected in series to further STOP push-buttons where present.
PHOTOCELL OR SAFETY DEVICE input INSIDE the gate (Normally Closed
contact). When these devices trigger during the opening phase, they tem-
porarily stop the gate until the obstacle has been removed; during the
closing phase they stop the gate and then totally open it again. Bridge the
connectors if not used. (7= COM - 8= CLOSE)
PHOTOCELL OR SAFETY DEVICE input OUTSIDE the gate (Normally Closed
contact). Then these devices trigger during the closing phase, they stop
the gate and then totally open it again. Bridge the connectors if not used.
(7= COM - 9= FOT)
Note: the photocell transmitter must always be supplied by termi-
nals no. 12 and no. 13, since the safety system test (phototest) is
carried out on it. Without this connection, the control unit does not
work. To override the testing of the safety system, or when the pho-
tocells are not used, set dip-switch no. 6 to OFF.
SAFETY EDGE input (Resistive sensitive edge 8,2 KΩ or with n.c. contact - see
DIP SWITCH 12 ). It works both during the opening phase and during the
closing phase, causing the temporary stop of the automation and a partial
inversion of its movement for 20 cm thus freeing any obstacle.
NOTE: if a resistive sensitive edge 8,2 KΩ is connected, set dip-switch
no. 12 to ON;
If a fixed safety edge with NC contact is connected, set dip-switch
no. 12 to OFF;
Jumper terminals if not used. (7= COMMON - 10= SENSITIVE EDGE)
Auxiliary circuits output 24V DC max. 15 W for photocells, receivers, etc...
(11= NEGATIVE - 12= POSITIVE)
24V DC output for transmitter photocell – phototest - max. no. 1 photocell
transmitters. (12= POSITIVE - 13= NEGATIVE)
24V DC max. 20W output for flashing light supply, flashing signal supplied
by the control unit, rapid for closing, slow for opening.
(14= POSITIVE - 15= NEGATIVE)
Output for OPEN GATE LIGHT 24 V DC, 3 W max; while the bar opens the
light flashes slowly, when the bar is open it stays on and while closing it
flashes at twice the speed. (16= POSITIVE - 17= NEGATIVE)
24 V DC, 15 W Output for auxiliary courtesy light. It comes on with the
control pulse and stays ON until after the manoeuvre for a time settable
through TauApp (default = 20 sec.) (16=POSITIVE - 18= NEGATIVE)
2 radio channel output - for control of an additional automation or for
nd
switching on lights, etc... (N.O. clean contact)
Warning: to connect other devices to the 2nd Radio Channel (area
lighting, pumps, etc.), use an additional auxiliary relay (see note at
end of paragraph).
WARNING: the default outlet is active monostable 2 sec. To switch it
to active bistable or to modify the activation time it is necessary to
use the T-WIFI.
Plug-in radio-receiver aerial input , for 433.92 MHz receivers only. (21=
GROUND - 22= SIGNAL)
Motor supply output 24V DC max. 200W. (23= POSITIVE - 24= NEGATIVE)
Encoder supply and input (25= WHITE signal - 26= GREEN negative -
27= BROWN positive)
