10 Fault messagesDE1… Variable Speed Starter 11/16 MN040011EN www.eaton.com 15310 Fault messagesDE1... variable speed starters feature several internal monitoring functions.If they detect a state deviating from a normal operating state, they will showa fault message:• Operation will stop• The Status LED will light up with a continuous red light• The Fault Code LED will flash red (see list of faults)• The relay contact (control terminal 13/14) will be openedFigure 92: LED with fault messageIf there is a fault message present, the Status LED will light up with acontinuous red light. Meanwhile, the Fault Code will flash a number of times(pulses) corresponding to the fault. After a pause of two seconds, the seriesof pulses will be repeated again (flashing frequency: 2 Hz). The faults thatoccur most frequently in real-life applications are documented on the DE1...variable speed starter’s housing:Table 44: Fault messages on the DE1... variable speed starter’s housingIn the event of mains undervoltage, the green Run LED will turn off and thetwo red Status and Fault Code LEDs will flash synchronously with afrequency of 2 Hz.When the mains voltage is switched on or returns, the two synchronouslyflashing Status and Fault Code LEDs will signal that the switched-modepower supply is working and the DE1... variable speed starter’s operatingstate will be checked before the Run LED starts flashing.Fault code(label on housing)Cyclical flashingfrequency of 2 Hzwith 2-second pauseMeaning1 pulse - overload 1 x Thermal motor overload2 pulses - external fault 2 x External fault message3 pulses - over voltage 3 x Overvoltage4 pulses - over current 4 x Overcurrent5 pulses - over temperature 5 x OvertemperatureRunStatusFault Code1 pulse - overload2 pulses - external fault3 pulses - over voltage4 pulses - over current5 pulses - over temperature
