POWER SUPPLY
IMPORTANT:
• Do not connect auxiliary relays or other devices tot he 18 V DC output (terminals 1 – 2)
to avoid malfunctions of the control unit. Use separated power supply / transformers
instead;
• do not connect switching feeders or similar apparatus close to the control unit that
may be a source of disturbance.
MEMORIZATION PROCEDURE
WARNING: After powering the control panel, wait 2 seconds before you start performing
the adjustment operations.
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: O/C, radio control or card button.
4_ the gate must start to close.
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.
When any adjusting devices (trimmers or dip-switches) on the control panel are operat-
ed, a complete manoeuvre must be carried out in order for the new settings to take effect.
LOGIC ADJUSTMENTS
TRIMMER
RALL. slowdown distance adjustment: from about 10 to 100 cm;
T.C.A. Automatic Closing time adjustment: from about 3 to 240 seconds (see dip-
switch no. 1);
T.R.A. 2nd wing closing delay adjustment from 2 to 15 seconds.
FRIZ. obstacle detection sensitivity adjustment.
NOTE: by rotating the TRIMMER FR. clockwise the sensitivity of the gear-
motor to obstacles diminishes and therefore the thrust force increases;
vice-versa, by rotating it counter-clockwise, the sensitivity of the gearmo-
tor to obstacles increases and therefore the thrust force diminishes.
