5_ when the gate has closed, after approximately 2 seconds a complete opening manoeuvre is ex-
ecuted 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 operated, a
complete manoeuvre must be carried out in order for the new settings to take effect.
7. 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 gearmotor
to obstacles diminishes and therefore the thrust force increases; vice-versa, by
rotating it counter-clockwise, the sensitivity of the gearmotor to obstacles in-
creases and therefore the thrust force diminishes.

TIMER-OPERATED OPENING AND CLOSING CYCLES
The opening and closing of the gate can be controlled through a digital timer equipped with a relay
contact on the output. The timer must be connected to terminals 18 - 20 (OPEN/CLOSE button) and can
be programmed so that, at the desired opening time, the relay contact closes until the desired closing
time (when the timer's relay contact opens, enabling the automatic closing of the gate).
The automatic closing function must be enabled by setting Dip-switch no. 1 to ON).
when the gate has opened, it closes automatically after the time established
through the T.C.A. trimmer;
when the automation is operational, a sequence of opening/closing commands
causes the gate to OPEN-CLOSE-OPEN-CLOSE etc.
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);
the gate ignores the closing commands during the opening manoeuvre and during
the automatic closing time. Therefore the A/C input works only by opening command;
following the connection of the photocell contact (input 15 - 17), the gate closes
automatically after 5 seconds;
