02.96 Malfunctions and warnings7 Malfunctions and warnings7.1 Fault signalsThe fault relay K760 at terminals X9-4 and X9-5 interrupts.The LEDs only serve the purpose of diagnostics. Their indications are volatile.Signal Description RemedySUPP. OK. (green) not lit Electronic power supply is lessthan DC 20 V or the internalgeneration of auxiliary voltagesis defective.Check the 20 to 30 V electronicpower supply; check fuses F1and F2.EARTH FLT.

If thefault lasts for longer than 100 ms, the fault relay drops out and remains dropped out until the fault isacknowledged.The fault is acknowledged by deactivation of the mains voltage (pause > 100 ms) or the electronic power supply(pause > 200 ms).Table for the excess voltage fault signal:Unit order number Rated ac-side voltage range Excess voltagewhenS500 closedS500 closedAC (V)S500 openAC (V)AC (V)Excess voltagewhenS500 openAC (V)6SE70..-.EE85-0AA0 208 - 230 380 - 460 309 5486SE70..-.FE85-0AA0 500 - 575 — 680 not permitted6SE70..-.HE85-0AA0 — 660 - 690 not intended 867Siemens AG 6SE7087-6AE85-0AA0 ENGLISH 7-1Common Rectifier Operating instructions
