TRIAC TEST
Failure of this component could jeopardise installation operation and safety.
That is why a control prior to every gate movement has been inserted.
Should there by any malfunction, the control unit locks and the open gate warning light blinks slowly.
SOFT START
The soft-start function determines a gradual start of movement without jolts on the gate. This function may
in any case be bypassed by inserting the jumper Jp1 (part 4 of Fig. 1).

ELECTRICAL CONNECTIONS

For connections, refer to table 1 and figure 2.
With existing installations, a general check of the state of the wires (section, insulation, contacts) and auxi-
liary equipment (photocells, receivers, pushbutton boards, key selectors, etc.) is recommended.
Tips for correct installation:
1. The wires entering the control unit, in the sealed box version, should be connected without altering the
initial protection rating IP56 if possible.
2. The cross section of the cables should be calculated according to their length and absorbed current.
3. Do not use a single cable of the "multi-core" type for all the connections (line, motors, controls, etc.) or in
common with other equipment.
4. Use at least two cables for the installation, e.g.:
cable (A) minimum wire section 1.5 sq.mm
- power supply line – motor lines -
- courtesy/flashing light line
cable (B) minimum wire section 0.75 sq.mm
- auxiliaries power supply
- controls – safety contacts.
5. When the control cables are very long (over 50 metres), de-coupling is advisable with relays mounted near
the control unit.
6. Any N.C. inputs (photocells, limit switches, fixed safety edge and stops) that are not used in the
control unit should be short-circuited with the common terminal terminal.
7. All the N.C. contacts linked with the same input should be connected in series.
8. All the N.O. contacts linked with the same input should be connected in parallel.
- THE INSERTION OF AN external, independent DISCONNECTING SWITCH (not supplied) of suitable
capacity for the load is envisaged for the control unit power supply.
- The equipment should be INSTALLED in a "WORKMANLIKE" manner by qualified personnel in
accordance with the laws in force and in compliance with standards EN 12453 and EN 12445
regarding automation safety.
