box to the Encoder. Confirm that K-Tech terminal LW+ is connected to Encoder terminal J3-1
and K-Tech terminal LW- is connected to encoder terminal J3-2. Ground the shield of the
cable inside the Encoder box.
Connect the terminal "Input 1" (J4) on the K-Tech electronics board to terminal "CAL" on the O.
Thompson Car Station board. Refer to the O. Thompson wiring diagrams for the exact terminal
location, as it will vary on job to job basis. This signal will be activated periodically by the Car
Station board, energizing the relay on the K-Tech board to re-calibrate the crosshead sensor.
The electronics box is now connected, the sensor mounted, and the unit is ready to be
calibrated.
