(*) In compliance with the corresponding application limits.
2 - Recognition of the connected devices
After the initial power-up (paragraph 3.11 - Refer to the full instruction manual),
the devices connected on the "Bluebus", "Stop" and encoder inputs must be
recognised by the control unit.
CAUTION! – The learning phase must be performed even if no device is
present that is connected to the control unit.
NOTE FOR MOTOR WITH INVERTER! – If a motor with MEIN family inverter
is used, prior to running the device learning phase, the function "L7
Inverter" must be activated; see Table 5 of paragraph 8.
The need to proceed is signaled by LEDs "L1" and "L2" present on the control unit
flashing at the same time.
To run the device learning phase proceed as follows:
01. Press and hold
down[Open] and [Set]
keys at the same time
02.
Release the keys when LEDs "L1" and "L2" start flashing quickly
(after approx. 3 seconds).
03. Wait a few seconds for the control unit to complete the device
learning phase.
04. At the end of this phase, the STOP terminal LED must be lit and
LEDs "L1" and "L2" must turn off (LEDs "L3" and "L4" may start
flashing to indicate that the positions have not be learnt).
This procedure must be repeated in the case of modifications to the
devices connected to the BlueBus and Stop terminals (for example, after
connecting a new device to the control unit). The operation must be
carried out also if an Inverter or a motor with encoder is connected.
3 - Recognition of limit positions on opening and closing
After the recognition of the devices connected to the control unit (paragraph 2), the
control unit must recognise the door's open and closed positions.
CAUTION! - Procedure for motors with electronic limit switch: after the
learning procedure for the opening and closing positions, 3 complete ma-
noeuvres must be performed. While these manoeuvres are performed, the
door progressively moves closer to the positions memorised previously,
until reaching the programmed positions.
If the door is in the closing position, it must be positioned manually at about 50
cm from the ground by using the emergency manoeuvre system (see motor in-
struction manual) to prevent, in case of inverted rotation, the load-bearing ropes
(sectional doors) from leaving their seat or the excessive tightening of the shutter
(rolling shutters).
CAUTION! – The learning phases must never be interrupted. If this occurs,
the entire learning procedure must be repeated. At the end of the learning
phase, if LEDs "L3" and "L4" flash, this means that there is an error. The
position recognition procedure can be repeated at any time also after the
installation.
4 - Recognition of limit positions on opening and closing with
electronic limit switch (encoder)
3 positions can be programmed, as described below:
Position LED Meaning
A1 L1 Maximum opening position desired. When the door
reaches this position it stops
AP L5 Partial opening position. It is the position in which the
door stops after giving a partial opening command.
A0 L8 Maximum closing position. When the door reaches
this position it stops.
Caution!
- if the direction of rotation does not correspond to the direction set (Open

= opening direction), you must disconnect the electrical supply and invert
the "V" and "W" connections (phase inversion) in the motor connector (fig.
19 - Refer to the full instruction manual).
- if, during the movement, the door stops and LED L6 flashes, the function
"Inverted rotation direction" must be set; refer to Table 5.
To carry out the procedure, proceed as described below:
01. Press and hold down [Set]
and [Close] keys for 3
seconds to start the position
memorisation phase.
LED L1 flashes: programming
position A1
02. Use the [Open] or [Close] key to move the door to the maximum
opening position.
03. Press the [Set] key for 3 sec-
onds to confirm position A1.
LED L1 stays on.
LED L5 flashes: programming
position AP
04.
If you do not wish to program the partial opening position, quickly
press the [Set] key twice to move to the new programming stage.
LED L5 stays off.
Otherwise continue the sequence.
05. Use the [Open] or [Close] key to move the door to the partial open-
ing position.
06. Press the [Set] key for 3 sec-
onds to confirm position AP.
LED L5 stays on.
LED L8 flashes: programming
position A0
07. Use the [Open] or [Close] key to move the door to the maximum
closing position.
08. Press the [Set] key for 3 sec-
onds to confirm position A0.
LED L8 stays on.
09. When the [Set] key is released, all LEDs are switched off.
10. Send an opening command by pressing the [Open] key to perform
a complete opening manoeuvre.
