12_ TECHNICAL MENU
The control unit is supplied with standard factory settings, suitable
to move most doors commercially available, in compliance with
European standards.
However a series of parameters may be modified, by means of
dipswitches 7-8 and trimmers TRM4, TRM5 and TRM6.
The function of these trimmers varies according to the position of
dipswitches 7-8, as specified in the table below.

Notes:
( ) if this parameter is modified, i.e. if the stopping distance
1
from the mechanical limiter is moved +/- forward, the value
"Opening limit position" (10) must be adjusted to guarantee
the space required to complete a complete manoeuvre.
Recommended procedure for adjustment:
1_ position dipswitches 7 and 8 on the combination re-
quired to modify the specific parameter;
2_ set ALL THREE trimmers to mid-way.
3_ press ENTER to confirm the parameters;
4_ perform a complete open/close manoeuvre and check
that the response is correct.
5_ adjust the trimmers;
6_ press ENTER;
7_ proceed as per point 4 to obtain the required response.
N.B. it is not possible to modify one parameter only. All
three parameters of the selected combination need to
be adjusted each time.
To restore the standard configuration to the control
unit (factory settings), press and hold ENTER for at le-
ast 5 sec.

13_ MALFUNCTIONS: TROUBLESHOOTING
The automation does not start
a_ Use a Multimeter to check presence of 230 Vac supply volt-
age.
b_ Check that the NC contacts of the card are effectively nor-
mally closed (3 green leds lit) and that the red leds for open-
ing commands are off.
c_ Set dipswitch 6 (fototest) to OFF;
d_ Set trimmers FRC and FRA to the maximum value;
e_ Use the Multimeter to check that the fuses are intact.
The radio control range is low
a_ Check that the earth connection and aerial signal have not
been inverted;
b_ Do not make joints to extend the aerial cable;
c_ Do not install the aerial at low heights or concealed by walls
or columns;
d_ Check status of the radio control batteries.
The door opens in the opposite direction
a_ Invert the motor connection (RED and BLACK wires on the
motor).
