There is an alternative way of arriving at the appropriate setting for the torque control potentiometer. Do
the following:
1.
Pass section of cable to be installed through machine as described in manual.
2.
Feed the cable into the beginning of a length of sample duct (approximately 15 feet long)
3.
Seal the open end of the duct
4.
Set the torque determined by the recommendation in this section
5.
Set the speed to maximum
6.
Start the machine and drive the cable hard into the sealed end of the sample duct
7.
The belts will stop turning as the torque limit has been reached.
8.
Repeat the above a few time, increasing the torque a little each time. Eventually the cable will buckle
at which point the torque is set a little too high so will need to be turned down slightly.
9.
The torque is now set such that the maximum pushing force with damaging the cable can be applied.
Note
:
This method may also be used to set the clamping force of the belts on the cable. Initially, the clamp arm
lever should be set so that the belts press very lightly onto the cable.
Carry out the test outlined above (drive the cable into the closed end of a sample duct). The belts will slip.
Repeat this procedure, each time increasing slightly, the pressure the belts apply to the cable. Eventually
the belts will stop turning because the torque limit has been reached. It is worth noting at this stage that
this approach may result in a great deal of force being applied to the cable. More than the cable can with-
stand without sustaining damage, sometimes it may be that the cable may be protected from buckling by a
combination of torque control setting and slip. The main purpose of the exercise is to install the cable as
far as possible without causing damage to the outer sheath, in some circumstances a compromise may be
found that uses a degree of torque control and slip.
7.7.3 CABLE AND DUCT SIZE SETTING ON REMOTE
Next you may want to select the size of the cable and duct, this will be transferred when downloading the
install data. Follow the steps below:
1.
When in the pre
-
installation screen press options by using the appropriate blue button
2.
Go down to
“
Cable/Duct
”
and press select
3.
Select
“
Cable size
”
4.
Next you will be able to increase the value up .020" (0.5mm) and down .040" (0.1mm) to get to the
correct value.
NOTE:
if decreasing from 0.0 the value will jump to .551" (14.0mm)
5.
Once the correct size is displayed press
“
BACK
”
again using the blue buttons. This will take you back
to the Cable/Duct size screen and will display the size selected.
6.
Go down to
“
Duct size
”,
press select and repeat steps 4 and 5.
7.
Press
“
BACK
”
to get back to the
“
OPTIONS
”
screen and press
“
BACK
”
again to get to the installations
screen.
