Position recovery WITHOUT the absolute encoder
consecutive times, the control unit starts a manoeuvre in position recovery mode.
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
the gate leaves into their original positions before locking the gate release again. The gate will resume normal operation
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:
1. The wings movement gets inverted on the mechanical strike plates (obstacle detection).
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.
• the wings resume the manoeuvre at low speed through to the striker plate.
• 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.

Position recovery WITH the absolute encoder (SMARTY
range only)
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.

Initial testing
The installer is required to measure impact forces and select on the control unit the appropriate speed and torque values
Make sure that the provisions in "GENERIC WARNINGS" are observed.
• Turn on the power supply.
• Check that the automation system motors rotate in the correct direction. If the leaves do not move correctly, swap
• Check that all connected controls are working correctly.
• Check travel and deceleration.
• Check that the impact force is correct, in compliance with EN 12453 and EN12445.
• Check that the safety devices are activated correctly.
• If the photocell test is enabled, check it is working properly by obscuring the photocells and giving a command: the
gate leaves must not move.
• If the battery kit is installed, disconnect from mains and check that the batteries are working.
• Disconnect from mains power and disconnect the batteries (if used), then reconnect. Check the correct completion
of the position recovery phase when opening and when closing.
• For SMARTY Series automation systems with absolute encoder installed, disconnect and reconnect power. Perform
a manoeuvre with the controls and check that the speed and deceleration values are correct. The position recovery
manoeuvre is not performed.
• If
(SMARTY REVERSIBLE only), check that the gate leafs are locked when the motors are stopped.

Maintenance
Perform scheduled maintenance every 6 months.
Check cleanliness and function.
If the unit contains dirt, moisture, insects or other foreign matter, disconnect from mains power and clean the board
