4.2) Recognition of the devices
After connecting up the power supply, the control unit must be made
to recognise the devices connected up to the BLUEBUS and STOP
inputs. Before this phase, LEDs L1 and L2 will flash to indicate that
recognition of the devices must be carried out.
!
The device self-learning phase must be performed even if
no device is connected.
1. Press keys [s] and [Set] 2 and keep them pressed down.
2. Release the keys then LEDs L1 and L2 start flashing rapidly (after approx 3sec)
3. Wait for a few seconds for the control unit to finish recognising the devices
4. The STOP LED must remain on when the recognitions stage has been completed, while LEDs L1 and L2 will switch off (LEDs L3 and L4
will eventually start flashing)
The connected devices recognition stage can be repeated at any time, even after installation, e.g. if another device is added. Please refer to
Paragraph "7.3.4 Recognition of other devices" for information about how to carry out another recognition process
4.3) Recognizing the door opening and closing
positions
After recognizing the devices the control unit must be made to rec-
ognize the opening and closing positions of the door. In this phase,
the door stroke from the mechanical closing stop to the mechanical
opening stop is detected.
Ensure that the drive belt is correctly tensioned and that the two
mechanical stops are fully secured.
1. Engage the carriage.
2. Press keys [t] and [Set] and keep them pressed down
3. Release the keys when the manoeuvre (after approx. 3s)
4. Wait for the control unit to complete the recognition phase: closing, opening and closing again of the door.
5. Pull the control cord to perform a complete opening manoeuvre.
6. Pull the cord again to perform closing.
During these manoeuvres, the control unit memorises the force required for opening and closing.
At the end of the self-learning process, if leds L3 and L4 flash, this means there is an error; see paragraph "7.6 Troubleshooting".
It is important that these manoeuvres are not interrupted, e.g. by a STOP command.
If this occurs, the self-learning process described in point 1 must be repeated.
The position recognition stage can be repeated at any time, even after installation (for example if one of the mechanical stops is moved); simply
repeat the procedure from point 1.
!
During the position search process, if the belt is not sufficiently tensioned, it may slip on the pinion. If this occurs, press the
[Stop] key to interrupt self-learning; tension the belt by tightening the M8 nut (D) as shown in figure 11, then repeat self-learning
from point 1.
4.4) Checking door movements
On completion of the recognition of the opening and closing posi-
tions, it is advisable to carry out a number of manoeuvres in order to
check the door travels properly.
1. Press the [Open] key to open the door. Check that door open-
ing occurs regularly, without any variations in speed; The door
must only slowdown and stop when it is between 30 and 20 cm
from the opening mechanical stop. Then, at 2÷3cm from the
mechanical opening stop the limit switch will trigger.
2. Press the [Close] key to close the door. Check that the door
closes regularly without any variations in speed. The door must
only slowdown when it is between 30 and 20cm from the closing
mechanical stop and stop against the mechanical closing stop. A
brief opening manoeuvre is then performed to release belt tension.
3. During the manoeuvre, check that the flashing light (if any) flash-
es at a speed of 0.5 seconds on and 0.5 aseconds off.

4. Open and close the door several times to make sure that there
are neither points of excessive friction nor defects in the assem-
bly or adjustments.
5. Check that the fastening of the gearmotor, the guide and the
mechanical stops are solid, stable and suitably resistant, even if
the door accelerates or decelerates sharply.
