The J2 terminal block is for the track circuit inputs. One rail is connected to terminal-1, the
opposite rail to terminal-2. Polarity makes no difference.
4.3.3 2300-528 Zepic III Board
The Zepic III board (aka SOTC board) operates on a voltage range of 9 to 24 VDC. This
board provides a consistent activation point independent of input voltage. The semiautomated
track circuit setup feature makes calibration quick and easy. Just place a shunt and push a
button.
