1. Should the spring not be properly
balanced, the onboard buzzer will alert the
user to this fault condition.
2. A handy diagnostic screen, complete with
graphic representation, can be found by
simply pressing the down arrow once while
in normal operating mode.
3. This screen will show the user exactly how
many turns of the tensioning nut are
needed to obtain optimum balancing of the
counterbalance spring and in which
direction.
4. The barrier must be operated at least three
times before the new adjustments will be
registered by the controller.
5. It is much easier to perform the tensioning
operation while the boom pole is in the
vertical (raised) position, as the spring will
be under significantly less tension.
Both of the lock nuts will
loosen/tighten in the same direction.
This might not be the expected
direction - if the lock nut does not
loosen/tighten try the other direction
Balancing the Spring
As the adjustment link is turned, the
boom pole moves up or down. It is
helpful to hold the adjustment link
with a second spanner during this
process
On the 6m and 4.5m SECTOR
variants, a 24mm socket must be
used on the tensioning nut, and a
19mm socket must be used for
the 3m
