29 - 30 - 31 encoder supply and input (29 = WHITE signal - 30 = BLUE negative - 31 = BROWN
positive);
32 - 33 13.5 Vac control unit power supply input – Supplied by the toroidal transformer and
protected by fuses on the 230 Vac power supply.
WARNING: After powering the control panel, wait 2 seconds before you start performing the
adjustment operations.
N.B. The gate must be equipped with the opening and closing safety stops.
When you have completed the installation procedures :
1_ position the leaf of the gate at approx. 1 m from the closing stop;
2_ set dip-switch no. 8 to ON;
3_ operate the automation using one of the following inputs: A/C, radio control or card button.
4_ the gate must start to close.
N.B.: if it opens, stop the programming procedure by resetting the electric panel (disconnect
the power supply to the panel for at least 5 sec. and set dip-switch no. 8 to OFF);
with the control panel disconnected, exchange the motor supply wires. Restart the
procedure from point 1.
5_ when the gate has closed, after approximately 2 seconds a complete opening manoeuvre is
executed automatically;
6_ when the gate has opened, set dip-switch no. 8 to OFF;
7_ the automation is now ready for operation.
Make the logic adjustments.
N.B.: When any adjusting devices (trimmers or dip-switches) on the control panel are
operated, a complete manoeuvre must be carried out in order for the new settings to
take effect.
TRIMMER
RALL. slowdown distance adjustment: from about 10 to 100 cm;
T.C.A. Automatic Closing time adjustment: from about 3 to 120 seconds (see dip-switch no. 1);
T.R.A. 2nd wing closing delay adjustment from 2 to 30 seconds.
FRIZ. obstacle detection sensitivity adjustment.
NOTE: by rotating the TRIMMER FR. clockwise the sensitivity of the gearmotor to
obstacles diminishes and therefore the thrust force increases; vice-versa, by rotating
it counter-clockwise, the sensitivity of the gearmotor to obstacles increases and
therefore the thrust force diminishes.
Dip switch
1 on: when the gate has opened, it closes automatically after the time established through the
T.C.A. trimmer;
off: the closing manoeuvre requires a manual command;
2 on: when the automation is operational, a sequence of opening/closing commands causes the
gate to OPEN-CLOSE-OPEN-CLOSE etc.
off: under the same circumstances, the same sequence of commands causes the gate to
OPEN-STOP-CLOSE-STOP-OPEN-STOP, etc. (step-by-step function) (see also dip switch 4);
