LNC-TC1 operation
When in Shift Kill mode the LNC-
TC1 cuts all engine torque by
disabling the ignition to all cylinders.
The LNC-TC1 does this based on
input to the orange Shift Kill Enable/
Activation wire and to the purple
Shift Load Signal wire. When using
a load cell type input, the LNC-TC1
will cut torque when the desired input
voltage on the purple wire is reached
(as set on the Kill Enable Offset
Voltage rotary dial) and for the length
of time set with the Kill Time rotary
switch. The torque cut length is adjustable from 25ms-95ms. When using an external device to activate
the torque cut, the length of time for the torque cut can either be controlled by the Kill Time setting (0
to E settings) or by the external device (setting F).
Load cell shift knob or lever input configuration:
The LNC-TC1 is designed to work with a 5 volt powered load cell with a 2.5V centering voltage and
+/-2.0V span. The load cell can be directional or non-
directional. The LPE load cells provide directional
output. LPE offers two different versions of this
type of load cell. One is a shift knob (L350170000)
and the other is an intermediate adapter that installs
in between your shifter mechanism or lever and the
shift knob (L350180000). See page 14 for images
of the LPE load cell input devices. Other companies
also offer load cell shift knobs and some companies
will install a load cell into your existing shifter lever
or knob. Just be sure to specify the above mentioned
voltage configuration.
In order to reduce ground offset related problems, it
is recommended that the LNC-TC1 supply the power
and ground for the load cell via the provided +5 volt
and ground wires.
Because the load cell output is 2.5 volts with no load, you can NOT just disconnect the load cell or put a
switch in the harness to disable the torque cut feature. Doing so will result in a 0 volt signal to the LNC-
TC1 which would be seen as a maximum load condition in one direction.
If you want to be able to disable the LNC-TC1 torque cut function, set both the “Kill Enable Offset
Voltage” and the “Kill Time” to the “F” positions and then make sure nothing is connected to the orange
wire (unplug the wire or put a switch in the wire).
Load cell shift knob operation:
A load cell shift knob or lever has a strain
gauge installed inside of it that provides a
signal that is caused by a change in length of
a resistor that is attached to the knob or lever.
The change in length of the resistor element
in the load cell causes a change in output
voltage across the load cell. At zero strain the
voltage across the load cell should be 2.5 V.
When load (strain) is applied to the shifter, the
voltage will then become 2.5V +/- 2.0V. The
maximum and minimum voltage across the
load cell is therefore 4.5V and 0.5V in tension
and compression, respectively.
