PHOTOCELLS TEST mode
To enable the test mode of the photocells connect
the supply of the photocells transmitter to the
terminal SC (no. 11, figure 8) instead of terminal no.
13 and set the parameter
configuration.
For every transmitted command, the control unit
turns off and on the photocells and makes sure
that the contact status changes accordingly: if all
goes well, the command will activate the engine;
otherwise, the system remains locked as there is a
fault at the photocells level.
NOTE: in this mode, at the terminal SC is always
present a voltage of 24Vdc, therefore that output can
no longer be used for the open door light.
If the battery is installed, it is advisable to connect
the supply of all external devices to terminal 11
(SC, see figure 9) and set
both settings, the supply to terminal 11 (SC) is cut
off when the automation is still in fully opened or
fully closed mode and it is powered by battery, thus
limiting the consumption of the back-up battery. If

Error signals
The operating parameters are stored in a non-
volatile memory (EEPROM) using control codes
that ensure their validity; "a possible" error at the
parameters level will be indicated on the display
and at the same time the control unit will block the
command activation.
Example: if an error should appear in parameter
21, on the display will appear the error message
21 ee
.
EE
indicates the presence of the error; the control
unit will be locked until the correct value is restored;
the operator must use the keys + and - to select the
numerical value appropriate for the installation and
then save it.
NOTE: if an error should appear, on the display will
always appear the "extended mode" numbering
indicated in the table on paragraph 10, even if
activated the simplified mode.
The following errors regarding the motor control will
be displayed:

to manually move it, if the control unit is powered
up, the following functions will be performed:
• Unlocking will be signalled by blinking message
