4.3 - Autolearning of the travel stroke
The rst time the control unit is powered up, an autolearning proce-
dure must be carried out to acquire fundamental parameters such
as the travel stroke length and deceleration points.
Press the + or - keys to view not only the status of the control unit, as
explained in the rst table in point 4.2, but also the count of the ope-

ning-closing operations performed. In the operation count display,
thousands, displayed without dots, alternate with units, displayed
with dots between them (e.g.: 50.000 = 50/0.0.0).
The display returns to the normal screen.
Malfunctions
This section lists a number of malfunctions which may occur.
SURGE OVERLOAD ALARM The motor’s current drawdown has increased very quickly
EFO
1. The gate has struck an obstacle.
2. Friction on runners or rack.
SAFETY EDGE ALARM The control unit has received a signal from the safety edge
EED
1. The safety edge has been pressed.
2. The safety edge is not connected correctly.
LIMIT SWITCH ALARM The limit switches are not working properly
ELS
1. The limit switches are damaged.
2. The limit switches are not connected.
3. Check the travel time which has passed without tripping of the limit switches.
PHOTOCELL ALARM Phototest fail outcome.
EPH
1. Check the photocell connections.
2. Check that the photocells are operating correctly.
ELECTRONIC OVERLOAD CUTOUT
TRIPPED
Motor not absorbing power
Eth
1. Check the motor’s power drawdown.
2. Check that the gate travels smoothly and that there are no obstacles.

AUTOLEARNING OF THE TRAVEL STROKE AND MAIN PARAMETERS, WITH
PRESET DECELERATIONS
The decelerations will be those set in the menu, with the same percentage during both opening and closing.
To program the decelerations in manual mode, move straight on to the next table.
1. Release the gate or door, move it onto the central position and lock it in place again. For customised pro-
gramming of decelerations, move on to the next section.
2. Hold down the + and MENU buttons SIMULTANEOUSLY for more than 5 seconds, until the screen shows
LOP and get ready to press the DOWN key (see illustration) if necessary.
3. If the rst operation is NOT opening of the gate, press the DOWN key to stop the autolearning.
Then press SS to restart the acquisition: the gate starts moving again, in the right direction. The motor opens
the gate at low speed to the opening limit switch (if the torque is not sufcient
to move the gate, delete the decelerations from the menu [LSI=0]). When the open limit switch is reached,
the gate sets off again in the closing direction at full speed, displaying LCL.
4. Wait for two complete operating cycles (2 opening and 2 closing strokes) to be completed and for the gate
to nish travel in the closed position (displaying --).
5. Perform a number of opening, closing and sudden stop commands to ensure that the system is solid with
no assembly defects.
All the main parameters are set with the default settings by the control unit. To customise the installation, proceed as described in point
4.4 below.
