PHOTOCELL TEST mode

By connecting the power of the transmitters of the
photocells to terminal block SC (no. 16) instead of
to terminal no 14 and by selecting the parameter
A8 O2
in the parameters extended mode, the
photocells test mode is activated (see figure 6).
For each command issued the control unit turns the
photocells off and on and checks that the status of
the contact changes correctly: only if this is so will
the command activate the motors, otherwise the
locked status is maintained.
NOTE: in this mode 24 VDC of voltage is still present
in the SC terminal block, therefore you can no longer
use that output for the gate open light.
If the battery is installed, another function available
A8 O3
) is the one providing to turn off the
power supply to all external devices (whose positive
supply terminal must be connected to the terminal
SC, see figure 7) when automation is stopped
and, in addition, even with test function enabled
at the input of photocells (
two setting, with automation fully open or closed,
there is no voltage on the terminal SC; and such a
condition turns out to be very useful to limit the
consumption of the backup battery.

Error reporting

The operating parameters are stored in a non-
volatile memory (EEPROM) with appropriate control
codes which ensure its validity; an error in the
parameters is shown on the display and at the same
time the control unit will not allow the command to
be activated.
Example: in the case an error occurring in parameter
21, the display would present the following type of
indication:
21 EE
"EE" indicates the presence of the error, the control
unit will be locked until the correct value is restored;
you must use the + and - buttons, selecting the
numeric value appropriate to the installation, and
then save it.
NOTE: in the case of an error in the parameter,
the "extended numbering shown in the table in
paragraph 4.6 is always displayed, even if the

simplified method has been activated.
The following errors relating to motor control are
also indicted:
OF St
calibration error (offset), system locked.
Cut the power, wait 10" and then try
again.
PrOt
The amperometric protection device
of the engine was enabled. To start the
engine, press the TEST button twice, or
give 3 motion-commands.
DaTa
Error in the data related to the length of
the stroke; it is necessary to run a new
programming. It is possible to unlock
the display to show the parameters, by
pressing the TEST key.

Position recovery mode

When you see both wings close at a slower rate than
usual and the flashing light is active in a different way
than usual (Also the two doors close one at a time, first
door 1 and then door 2), it means that the control unit
is retrieving the references: in this situation you have
to wait until the flashing has stopped to issue new
commands, as it is necessary to let the manoeuvre
finish. If you do not let the manoeuvre finish, the
movement of the wings will remain imprecise because
the correct references on the fully opening and closing
positions are not available. The only exception is
given by the motor with articulated arm if it uses
the opening limit switches: the activation of the limit
switch enables instant recovery of door position.
During the repositioning manoeuvre the flashing
is activated in a differentiated manner (3 seconds
on, 1.5 seconds off) to highlight that this is a special
manoeuvring stage: only when the flashing returns
to normal will the control unit have recovered the
position references. The repositioning manoeuvre
is performed at low speeds, different from that set;
in the case where the set speed is very low, then the
repositioning is performed at that speed (without
further decreases).
The loss of references is caused by a blackout or
if the obstacle detection based on the current
consumed by the motor is active three times at
the sam point, thus indicating that there is a stable
obstacle on the road.
