Mechanical release
In the event of a fault or mains power loss, the gate may be released and opened manually.
For further information, refer to the locking/release operation in the manual of
the automation system.
If the gate releases with the controller unit powered, the message
When the release system is restored to the normal operating position, if the gate is not completely open or completely
closed the next time a command is received, the control initiates a position recovery procedure (see chapter 20).
Activating one of the two limit switches immediately reacquires the position.

Position recovery mode
After a mains power outage or after mechanically releasing the gate, if the gate is not completely open or
completely closed the next time a command is received, the control initiates a position recovery procedure:
• The gate starts a low speed manoeuvre.
• The ashing light ashes with a different duty cycle than normal (3 s on, 1.5 s off).
• The control unit recovers the installation data during this procedure. Warning! During this procedure, do not use
any controls until one of the two limit switches is reached.
• Activating one of the two limit switches immediately reacquires the position.
When the control unit receives a command signal after a power failure or after the motor has been mechanically
released, if the gate is completely open or completely closed, it initiates a position recovery procedure to precisely
determine the exact position of the gate.
The gate releases the limit switch, brie y stops and resumes the manoeuvre at the speed set at parameters

For BG30/1400/R motors only. If the control unit detects that the gate has been moved manually by more than 3
cm from the initial position, it initiates a position recovery procedure.

Initial testing
The testing must be performed by quali ed technical personnel.
The installer is required to measure impact forces and select on the control unit the
appropriate speed and torque values to ensure that the motorised door or gate remains
within the limits de ned by the standards EN 12453 and EN 12445.
Make sure that the provisions in Chapter 1 "GENERIC WARNINGS are observed.
• Turn on the power supply.
• Check that all connected controls are working correctly.
• Check that the release handle works correctly. The message
display.
• Check travel and deceleration.
• Check if the impact forces are compliant with the EN 12453 and EN 12445 standards.
• Check that the safety devices are activated correctly.
• 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.
Starting with the gate stopped in an intermediate position, check that the position
recovery procedure is completed correctly for both the open and closed positions.
• Check that the limit switches are set correctly and function correctly. If necessary, adjust
the motor installation position.
• Check that there is a gap of at least 2-3 cm between the gate and the mechanical stop at
the end of the manoeuvre.
