ELECTRICAL CONNECTIONS

For connections, refer to tables 1 and 2 and figure 16.
In the case of existing systems a general check should be made of the condition of wiring (cross-section, insulation,
contacts) and auxiliary equipment (photocells, receivers, pushbutton panels, key-operated switches, etc.).
1) The cross-section of the cables must be calculated on the basis of their length and absorbed current.
2) To connect the electric lock, use a wire with a minimum cross-section of 1.5 mm
3) Do not use a single "multi-pole" type cable shared with other appliances.
4) When very long control cables are used (over 50 metres), decoupling is recommended by means of relays
installed in the vicinity of the control unit.
5) All N.C. contacts associated with the same input must be connected in series.
6) All N.O. contacts associated with the same input must be connected in parallel.
Recommendations for correct set-up:
- All N.C. inputs (photocells, sensitive edge and stop) that are not used in the control unit must be shorted with the
common.
- For the control unit power supply, the INSERTION OF AN EXTERNAL DISCONNECT SWITCH (not supplied) is
envisaged, which must be independent and sized according to the load.
- The equipment must be installed PROFESSIONALLY by personnel with qualifications as envisaged by current
legislation and in compliance with the standards EN 13241-1 and EN 12453 governing safety of the automation.

Connect this output to the primary winding of the
supplied transformer
Connect to 230 Vac line. See electrical connections
On during the manoeuvre. Activation can be set in
advance (pre-flashing): see function dip switch no. 5
By combining dip switches 3 and 4 it is possible to
obtain other functions with this output (see table 3)
Powered with every opening start
On closing it stops the motor then opens the gate
completely. See table 2 for the types of connection.
Inverts travel during closing.
Connect this input to the common if not used.
Blocks all functions.
Connect this input to the common if not used.
See function dip-switch nos. 1 and 2 (table 3).
Permanent for power supply of photocells and external
receivers.
If a receiver is connected to the specific connector, see
aerial specifications as required by the manufacturer.
Connect this input to the secondary winding of the
transformer supplied (22V)
