 Fault Status
The Fault LED located at the bottom left will turn on during a fault
condition The occurrence of a fault indicates that user intervention is
required to restore operation and these indicators attempt to provide the
diagnostic information needed to accomplish this
Fault LED (flashing)  Other LED Fault Condition
-mA Input LED flashing Command Signal Fault Input signal is
-mA mode and the input signal is less
than mA or greater than mA

Feedback Potentiometer Fault
potentiometer voltage is outside of the
V-V range when near limits
Calibration LED Calibration Fault Calibration failed due
to Feedback Potentiometer Fault or the
motor was not able to reach end of travel
in expected time
