Fail-safe/Lock Mode
When the barrier is in Fail-safe
Mode, the boom pole can be
manually moved by hand.
In Lock Mode, the boom pole is
locked in the raised or lowered
position and cannot be moved by
hand.
These configurations are
implemented by setting the top and
bottom locking stops on the gearbox
in different positions.

• For a right-hand boom to be
placed in Lock Mode in the raised
