PRODUCT INTRODUCTION
The Torque Hub utilises the same technology as our Torque Logic, it delivers over 99% accurate
torque readings. Data is sent over a robust 2.4 GHz RF FHSS signal to the hand held display / data
logger. The Torque Hub measures not only torque, but also inclination.
TECHNOLOGY
Utilising strain gauges, internal CPU, RAM and other electronics, the Torque Hub can guarantee
highly accurate, real time torque readings. An inclinometer built into the Torque Hub ensures that you
maintainaconsistent angle of insertion. The Torque Hub software records important data such
aspile number, final torque, peak torque and elapsed time. This data can be exported to an
Excel spread- sheetand transferred by e-mailor memorystick to your engineer/customer.
SAFETY
Consistent andreal time monitoring oftorque will prevent over-torque which can often resultin pile
failures (piles sheared or buckled). The inclinometer also removes the need (and associated risk) for
personnel tostand beneath the drive head toassist the operator in maintaining a proper insertion

TORQUE HUB INSTALLATION
1.Attach the harness to
the back of the display,
making sure the male and
female pins line up and
the connectors are tight.
2.Securely mount the display
using the magnet or suction
cup assembly. Try to point the
back of the display so it's
facing the hub.
3.If your unit comes with an
antenna. Make sure it is not
adjusted and laying down in
the horizontal position. Also
make sure the antenna is not
damaged, crushed or covered
in clay or grease.

4.Connect your power using
a cigarette lighter, hard
wiring or digger derrick plug
adaptor.
3. Mount the hub to the drive
units shaft and secure it with
locking pin and R Clip.

5.Turn the hubs power on.
Make sure the power switch
has a solid red light. If the
light is flickering or does not
come on there is a problem.
Give the hub some movement
by patting it with your hand or
movement with the drive. This
wakes the hub up.
6.Turn display power on.
Check for solid red light on
the switch.
 Make sure the power cable is plugged securely into the power connections and the cable is
not going to be caught on anything. Wait for the display to load.
 Once the display is running go to the “menu” button, then to “connect to pin or hub” button.
You will see a white screen with “please wait…” connecting may take a couple minutes.
 A screen will come up with a hubs serial number, highlight it and “connect” button. Do not
select “channels” that is for multiple hub connections. Sometimes for difficult connections,
removing the display from the ball mount assembly can help speed up connection. Replace it
when you are connected. Note: If a “failed to connect” message comes up go back to the main
display and wait, the display and hub are exchanging data and they will connect.
 You will know if the hub is connected when you see the hubs serial number in the top middle
of the main screen. The battery charge will appear under it. You may also see some torque
fluctuation in the gauge. Some noise is normal operation. Some torque may show depending on
how tight and even the adapter was installed. Note: The process of connecting is faster if the
hub and display stay together as a unit. Displays and hubs can be mix and matched but
connecting may take longer when this is done.
