C. LIM (red) – The C.LIM or Current Limit LED should NEVER come on. This diagnostic light is used
to determine the condition of the treadbelt and deck. The SCR board has a built-in amp meter. When
the treadbelt belt and deck system wears, the amperage will increase. When this amperage reaches
its max limit, the lower board will shut down its power (treadbelt will slow down / low torque) to the
drive motor and the C.LIM LED will illuminate.
SPD (yellow) – The SPD LED flashes on and off (relative to speed) when the speed sensor is
operating properly.
GRD (red) – The GRD LED should NEVER come on. It illuminates only when the elevation
potentiometer becomes out of calibration.
SERIAL (red) – The SERIAL LED should NEVER come on. It illuminates only when there is a serial
error. This could be a loose or pushed pin on the main wire harness.
+5V (green) – The +5V light comes on when there is power going to the Upper Display. If the light is
not on check wire harness for connections. If it ‘s not the wire harness then the MCB is defective.
