Do all links to push-buttons and photo-devices (paying attention to the supply polarity).
Jumper connect all the N.C. lines which are not used to the common (clamp n. 1).
If several couples of photo-devices are installed, contacts must be put into Series.
Through the self-diagnosis leds, check the working of the external commands, the contacts of limit switches
and photo-devices.
Connect the open gate pilot, the electro-lock, the blinker and the two motors to the proper outputs.
Unused outputs must be insulated.
Place all the central unit board trimmers at mid-course.
Select the right voltage for the electro-lock.
Exclude the automatic closing for the moment.
Place the automation at mid-course manually.
Disconnect the device of manual release of the motors.
Keep the power cables away from the control cables. To avoid interference use two separate sheaths (see
EN 60204-1 15.1.3).
Before any intervention on the plant disconnect the 230Vac line and the batteries.
The push the Aperture push-button: if the automation moves towards closing press the Stop push-but-
ton, disconnect the 230Vac, then invert the motors connections. Connect again the 230Vac and press the
aperture push-button; adjust the cycle speed through the trimmer B, according to the standard in force
and wait for the arrival to the limit switch.
Adjust the intervention of the braking circuit, by placing the cam on the limit switches and adjusting the
trimmer C for an easy stop.
Press the step-by-step push-button; do the motor torque adjustment according to the standard in force
through the trimmer A so that with a light effort the movement can be stopped; however it is advisable to
follow the standard.
N.B.: act on the trimmers very slowly in order not to stop the automation.
Verify then the working of the securities taking care that:
•
by pressing Stop in any condition, the plant stops and waits for an order;
•
the intervention of the photo-devices in the closing phase, causes an immediate, complete re-aperture,
while in the aperture phase it causes a momentary stop.
N.B.: any time the manoeuvres create confusion, disconnect the net for a few seconds, then give voltage
again and proceed with the tests.
N.B.: if possible, avoid the extreme adjustments of the spped and power trimmers.
N.B.: connect the wing which supports the electro-lock to the clamps 21, 22 of the motor 1, in order to allow
the release of the wing bolt.
N.B.: it is important to link the two motors with cables of the same length in order to avoid speed differ-
ences between them.
N.B.: the minimun section of the motor cables should be as follows:
•
1.5mm
for lengths up to 1 m.
2
•
2.5mm
for lengths up to 3 m.
2
•
4.0mm
for lengths up to 6 m.
2
It is advisable to cable the two motors to the switchboard with cables of the same length and diametre.
If no limit switches are available, take care that the wings, once in contact with the mechanic stop, are not
under effort but stop immediately because of the amperometric sensor; if not, increase the sensitivity of
the latter by turning the trimmer A counterclockwise.
