Operating principle of the EDS3365FAULT curveThe possible frequency range is shown by the curve (FAULT curve) which follows.This indicates the range in which residual currents are displayed as a FAULT. Ingeneral, residual currents > 1 A are displayed accordingly, and independently of thefrequency.Outside of the admissible range, FAULT messages may be given if residual currentsoccur. Likewise, excessively high leakage capacitances can lead to FAULT messages.These messages are displayed in the menu of the EDS165-3.FAULT FAULT-Kurve CurveIndication FAULT > 11000900Differenzstrom (mA)Residual current (mA)800700600500400300200100IndicationFAULTAdmissible Range08121822252735404448Frequency Frequenz (Hz) (Hz)54586580100120EDS3365 electrical interference. The curve indicates the maximum residual current before aFAULT indication is given.A sophisticated filter circuit and electronic system avoids malfunctions due toextraneous currents < 1 A.The following FAULT conditions may be indicated on the display of the EDS165-3:• Short circuited current clamp or current transformer connection. Display: no• Interrupted current transformer connection, or no current clamp or currenttransformer connected. Display: no• A residual current > 1 A through the current clamp or the current transformer.• The current transformer signal cannot be evaluated due to interferences.• The leakage capacitances in the system, or in an output of the system, are toohigh.12TGH1320E/03.2000
