13. DETERMINING MAXIMUM TORQUE SETTING
When preforming an installation of a larger or stiffer fiber it may
be necessary to use a straight set of blowing plates. To ensure
the integrity of the fiber at all times during the installation it is
crucial a test is performed. This test will provide the installer
with the maximum torque setting for the machine such that if
the fiber hits a blockage at speed, the fiber will not be damaged.
•
Set the machine up as per section 6 using non
-
buckle plates
(therefore no buckle shuttle will be present).
•
Instead of attaching to the installation route use a 5m length
of the same tube. Use a stop end kit to block the end of the
tube.
•
Set the speed to the maximum installation speed to be used.
•
Set the torque to approximately 10%.
•
Press
‘
start
’.
The machine will now accelerate to the speed
setting.
•
When the fiber hits the end stop the machine will either stop
and leave the fiber undamaged or continue to install and
break the fiber, in either case press
‘
stop
’
to prevent the ma-
chine from trying to continue the install. Reduce or increase
the torque setting as appropriate for the outcome of the pre-
vious test and perform the test again. Through several itera-
tions a torque setting just below the value which would
break the fiber should become apparent.
