LNC-TC1 load cell input modes (also see Table A on page 14):
The LNC-TC1 has two modes of operation for the load cell input. One uses the directional load
information (Voltage Mode) and one ignores the directional information (Time Based Mode).
Voltage Mode and Time Based Mode are controlled by the orange Input On wire, the rotary Kill
Enable Offset Voltage switch and the rotary Kill Time switch. If 12 volts is applied to the orange Input
On wire and the Kill Enable Offset Voltage switch and the Kill Time switch are both set to positions
0-E, then you will be in Voltage Mode.
If nothing is connected to the orange Input On wire and the Kill Enable Offset Voltage switch and the
Kill Time switch are both set to positions 0-E, then you will be in Time Based Mode.
Voltage Mode:
When in Voltage Mode, the LNC-TC1 uses the directional load information to prevent multiple torque
cuts when the shifter is pulled in the same direction. When in this mode and connected to a directional
output type load cell type shifter, once a torque cut occurs in one direction, the LNC-TC1 will not cut
torque again until it sees the shift lever cross back to zero load (2.5V) and then go the other direction
in load. So if you pull back on the lever and apply a load that goes below 2.5 volts, the LNC-TC1 will
not perform another torque cut until the lever is pushed forward and the load cell output goes above 2.5
volts.
Time Based Mode:
When in Time Based Mode the LNC-TC1 ignores the directional nature of the load cell input signal
(if you are using a directional load cell). To reduce false or redundant torque cuts, the LNC-TC1 waits
0.050 seconds (50 msec) after a torque cut occurs before it will allow another torque cut to occur.
Anything above or below the 2.5 volt centering voltage (0 load) that meets the Kill Enable Offset
Voltage setting will trigger a torque cut. This mode may be needed in road racing conditions where you
may not change gears in order. This mode is also needed when using the LNC-TC1 with a sequential
type transmission where all upshifts involve pushing up or pulling back on the shift lever. This mode
must be used when non-directional type load cells are used.
Momentary switch or toggle-switch type shift knob operation:
When using a momentary switch on your shifter or a toggle-switch type shift knob (on-off type spring
loaded switch) then the momentary switch should be wired such that when the switch is depressed,
+12 volts are applied to the orange Input On wire. The Kill Enable Offset Voltage switch should be set
to the F position (ALT). The length of the torque cut can be controlled two ways when in this mode. If
the Kill Time switch is set to positions 0-E then the LNC-TC1 will cut the engine for the length of time
specified by the switch position (0.025 to 0.095 seconds). If the Kill Time switch is set to position F
(OFF) then the LNC-TC1 will cut the torque for as long as the momentary switch is held (for as long as
12 volts is applied to the orange Input On wire).
