5. TERMINAL BOARD M3 (LOW VOLTAGE) CONNECTIONS - DESCRIPTION
5.1 STOP
Terminals "6-7" (Com - Stop). The status of this input is signalled by LED 1. This circuit is connected to any device (e.g. button,
pressure switch) which, when a contact is opened, can stop the gate motion.
Note: If STOP devices are not connected, jumper connect the input. To install multiple STOP devices, connect the NC
contacts in series.
5.2 PULSE A - TOTAL OPENING
Terminals "6-8". (Com - Pulse A). The status of this input is signalled by LED 2. This circuit is connected to any device (e.g. button,
radio control, etc.) which, when a contact is closed, generates a gate opening and/or closing pulse.
Note: To install multiple pulse devices connect the contacts in parallel.
5.3 PULSE B - PARTIAL OPENING
Terminals "6-9". (Com - Pulse B). The status of this input is signalled by LED 3. This circuit is connected to any device (e.g. button,
radio control, etc.) which, when a contact is closed, generates a gate opening and/or closing pulse. The opening time has
a fixed lenght of 10 seconds.
Note: To install multiple pulse devices connect the contacts in parallel.
5.4 CLOSING PROTECTION PHOTOCELLS
Terminals "10-11" (Com - Photocells). The status of this input is signalled by LED 4. This circuit is connected to any safety device
(photocells, pressure switch, detector, etc.) which, when a contact is opened, acts as a safety on the closing motion. The
effect will vary depending on the settings performed using dip-sw 4.
Note: To install multiple safety devices connect the NC contacts in series.
Note: If safety devices are not connected, jump connect the input.
It is possible to prevent the gate from closing by connecting a 24h timer in series to the closing photocell circuit.
6. TERMINAL BOARD M4 (LOW VOLTAGE) CONNECTIONS - DESCRIPTION
6.1 OPENING LIMIT SWITCH
Terminals "12-13" (Opening limit switch - Com). The status of this input is signalled by LED 5. This circuit is connected to the
opening limit switch.
6.2 CLOSING LIMIT SWITCH
Terminals "13-14" (Com - Closing limit switch). The status of this input is signalled by LED 6. This circuit is connected to the closing
limit switch.
6.3 ACCESSORY POWER SUPPLY
Terminals "15-16". (Com / +24 Vdc). Warning: the max. load for the accessories is 500 mA.
The unit is designed to house a single channel radio-receiver module. To install the module, cut off the electric power supply
and insert the module into the special connector M5 inside the unit.

5 - Opening limit switch
6 - Closing limit switch
Note: Bold is used to indicate the led condition with the gate at rest.
9.1 ELECTRONIC CLUTCH
To adjust the anti-crushing system tripping threshold use trimmer "A". To reduce the torque, turn the trimmer counterclockwise.
To increase the torque, turn the trimmer clockwise. It is recommend to calibrate this torque to meet current standards.
9.2 PAUSE
To adjust the pause duration (for automatic operation), use trimmer "B". The duration can be adjusted from 8 to 200 seconds.
9.3 OPEN/CLOSE
To adjust the duration of the gate opening/closing time, use trimmer "C". The duration can be adjusted from 10 to 75
seconds. Note: To obtain maximum system efficiency, adjust the opening/closing time so that the electric motor can be fed
for a few seconds after the gate has reached the limit switch.
