Initial search for mechanical stops
The "Initial search for mechanical stops” procedure is automatically performed as the first manoeuvre after installation.
Table “A” Activating the initial search for mechanical stops:
1. Release the motor and move the door manually so that it is free to move during the opening and closing manoeuvres; block
the motor.
2. Briefly press the “Open” button (ref. I, Fig. 1) or the “Close” button (ref. K, Fig. 1) on the board or give a command impulse
to the inputs and wait for the control unit to perform a slow closing manoeuvre to position 0, a slow opening manoeuvre to
position 1 and a rapid closing manoeuvre to position 0.
N.B. If the first manoeuvre after the command is an opening manoeuvre, give another command to stop the procedure and
invert motor polarity.
3. When the above procedure has finished, a mathematical operation is carried out to calculate position A (required opening)
at a few centimetres from the maximum open position, position B (partial opening) at about 3/4 from position A, and the RA
and RC positions required for slowing down.
4. The "Initial search" for the mechanical stops has terminated and the gear motor is now ready for use.
N.B. 1. If one of the safety devices cuts in or another command impulse is given during the "Initial search for mechanical stops", the door
will immediately stop moving and the above operations will have to be repeated from the beginning.
3.2) Automatic search for mechanical stops
As an alternative to the “Initial search” the “Automatic search for the mechanical stops” procedure can be performed at any time. This proce-
dure automatically searches for the mechanical stops (position 0 and position 1) in precisely the same was described in the initial search sec-
tion.
Table “B” Activating the automatic search for mechanical stops:
1. Set the Dip Switches as follows:
2. Release the motor and move the door manually so that it is free to move during the opening and closing manoeuvres; block
the motor.
3. Press the “Close” button (ref. K, Fig. 1) and wait for the control unit to perform a slow closing manoeuvre to position 0, a
slow opening manoeuvre to position 1 and a rapid closing manoeuvre to position 0.
N.B. If the first manoeuvre after the command is an opening manoeuvre, give another command to stop the procedure and
invert motor polarity.
4. Using the value of this position, a mathematical operation is carried out to calculate position A (required opening) at a few
centimetres from the maximum open position, position B (partial opening) at about 3/4 from position A, and the RA and RC
positions required for slowing down.
5. The "Automatic Search" for the mechanical stops has terminated and the gear motor is now ready for use.
N.B. 1. If one of the safety devices cuts in or another command impulse is given during the "Automatic search for mechanical stops", the
door will immediately stop moving and the above operations will have to be repeated from the beginning.
3.3) Memorisation procedure
At the end of the programming sequences of some parameters described in the next few paragraphs, the phase "Memorisation proce-
dure" will be seen several times. This operation is used to transfer the value of the parameter required to be programmed into the perma-
nent memory of the control unit.
Table “C” Performing the memorisation procedure:
1. Press the “Memory” button (ref. J fig. 1) for at least 3 s, after 3 s the OK (ref. R, fig.1) led will flash quickly
2. Release the “Memory” button, the “OK” led will continue to flash quickly for another 3 s.
3. Within 3 s quickly press the “Open” and “Close” buttons (refs. I and K, fig. 1) together; when these two buttons are pressed
together, the ok led will switch off.
4. Release the two open and close buttons; the “Ok” led will light up for approx. 2 s as confirmation that the memorisation pro-
cedure of the selected parameter has terminated correctly
