  41. PVE Identification The Function 2013

  42. 2013 • PVE Identification

  43. 2013 • PVE Identification Fault monitoring description The input voltage is continuous monitored. The acceptable signal range is between 15% and 85% of the supply voltage. If Signal voltage goes outside of this range, the system will switch into an error state. Input signal monitoring If one of the wires to the LVDT sensor, or inside the sensor, is broken or shorted, the system will switch ínto an error state. Transducer supervision The spool position must always correspond to the position requested by the input signal. If the spool is 15% farther from neutral (providing more flow) than requested, the system detects an error and will switch into an error state. Supervision of the closed loop

PVE Identification 2013 Fault monitoring description Acceptable Working Signal range: Spool position error Supply voltage: signal range: Nominal 100 % 100 % 100 % 11-32 volts = 100 % 85 % 85 % 85 % 75 % 75 % Spool position > 15% ==> ERROR Working Input signal range 50 % 50 % 50 % 50 % + Deadband 7% _ Working range Input signal > 15% ==> ERROR Spool position 25 % 25 % 15 % 15 % 15 % 0 % 0 % 0 % 0 %
