The SMARTY/EMA absolute encoder (installed as standard on SMARTY REVERSIBLE units and optional on SMARTY
IRREVERSIBLE units) allows the controller to reacquire the position immediately after each new command signal received.

duty cycle than normal (3 s on, 1.5 s off).
The control unit recovers the installation data during this procedure. Warning: Do not use any controls until the gate
has performed a complete manoeuvre for both leaves.
If the gate is released in the completely open or completely closed position with the control unit powered, always return
WARNING: Releasing the gate in an intermediate position is not recommended, at it may cause the leaf position parameters
to be lost (see parameters
Should the wings not be returned to the same position in which they were before the manual handling, the data relative
to their position will be lost, therefore:

2. Activation of a PP command (step mode) activates the opposite manoeuvre (example: if the gate was closing, it
opens).
3. The control unit detects an anomaly in the motor revs count and automatically:
• activates the position recovery mode;
• stops the motors for 0.4 s.
•
• On the subsequent Step by Step command (PP), the wings carry out the manoeuvre at low speed again.
4. Leave the wings to carry out a complete manoeuvre to restore normal operation mode.

encoder to reacquire the position of the gate leaf immediately.
If the control unit detects that the gate leaves are not positioned correctly, it corrects the error automatically.
For example: if the control unit receives a close request but the gate leaves cannot close, the unit executes a complete
open cycle and then closes the leaves after 1 s (even if automatic closure is not enabled) to restore the correct alignment.
Warning: Do not use any controls until the gate has performed a complete manoeuvre for both leaves.
