When the controller detects an anomaly, it shuts off control outputs and displays an error code on the PV screen. Error Code Potential Cause Corrective Action oPEn Sensor burnout or open circuit. Check sensor probe connection and replace wiring if broken. UUUU Input signal is over-range (too high).
: Before connecting to any aircraft system, the 9240SI should perform an internal self-test. Set the function selector to the TEST position. A successful test result is typically indicated by an "OK" message on the display or indicator. 9240si loop controller user manual
RTD (PT100): Connect the source wires to 7 and 8, and the compensation wire to 9. When the controller detects an anomaly, it shuts
: Measures the parallel capacity of the loop and calculates the equivalent cap Z sub c impedance at 1kHz. Combined Mode UUUU Input signal is over-range (too high)
The controller will force the system through 2 to 3 oscillation cycles.
