- when the gate is open the closing commands are inhibited,
Using the professional learning, the EDG/PED input can be set as internal photocell:
- in closing phase it provokes an inversion of direction when cleared,
- in opening phase it provokes a STOP and opening continues when cleared,
- when the gate is closed it delays opening until it is cleared,
- when the access is open it inhibits the closing commands.

Safeties Self-test
The control unit has a self-test function of the safeties connected to the “PHO” input of the control unit; it
switches off the transmitter to check the commutation of the corresponding receiver contact before the
execution of each manoeuvre. In this case, the “gate open warning light” is not available.
To activate this self-tes t function proceed as follows:
- switch
DIP 8
“PHTEST” to ON
- connect the positive of the photocell transmitter power to terminal 10 (“+TX”)
With the Self-test function active the
photocell transmitters are only powered when the manoeuvre is
taking place,
thus giving a major saving of energy.
If the enabling of the safety self-test is not required
- switch
DIP 8 “PHTEST” to OFF
- connect the positive of the photocell transmitter power to the terminal 9 (“+V”)

TRIMMER “FOR”- MOTOR SPEED
Trimmer “FOR” adjusts the voltage applied to the motors during operations, which means adjusting the speed of the motors.
With the trimmer turned fully counter-clockwise the speed of the motor if 50% of the maximum speed.
With the trimmer at half travel the speed of the motor if 50% of the maximum speed.
ATTENZION: Changing the setting of trimmer “FOR” requires repeating the learning procedure, since
the travel times and the slow-down start times change.
EXAMPLE
Speed 50%
EXAMPLE
Speed 75%
EXAMPLE
Speed 100%
5.4
TRIMMER “DEL”- DELAY BETWEEN MOTORS
Trimmer “DEL” can be used to adjust the delay between the two motors in opening and closing operations.
If the trimmer is turned fully counter-clockwise, the delay is 0 both in opening and in closing, and the two leaved
will move together. In all the other positions of the trimmer, the delay in opening is 3 seconds and the delay in
closing varies from 0 to 15 seconds according to the position of the knob.
EXAMPLE
delay 0 in opening
delay 0 in closing
EXAMPLE
delay 3 seconds in opening
delay 7 seconds in closing
EXAMPLE
delay 3 seconds in opening
delay 15 seconds in closing

TRIMMER “PAU” - “OPENING AND CLOSING” OPERATING MODE
5.5.1
Time controlled automatic closing mode
Switch the
dip-switch 6
to OFF and the
dip-switch 7
to ON.
Set the “
PAU
” trimmer in an intermediate position according to the pause time desired. The pause time can be
set between 3 and 60 seconds and is increased by rotating the trimmer clockwise.
EXAMPLE
pause time about 1 sec.
EXAMPLE
pause time about 30 sec.
EXAMPLE
pause time about 60 sec.
In this mode, if a command is received via radio or via the “STR” input, the control unit does the following:
- drives the two motors without 2
nd
motor delay if the
DEL trimmer is turned fully counter-clockwise
,
with a
2
nd
motor delay
of 3 seconds for all the other positions of the DEL trimmer
- drives the motors for one second at reduced speed (softstart) and then at the speed set on the FOR trimmer.
