SITOP select fault diagnosis - rapid and reliable A&D SE PS SITOP select Automation and Drives Reasons for selective triggering failure when fault occurs Long load lines Creeping short circuits Line circuit breakers dimensioned too large Consequences Plant standstill due to drop in 24 V power Trouble-shooting much more difficult Long standstill times Reason for undesired triggering during operation Excessive current peaks during startup Consequence Malfunction, machine/plant switches off The situation today The solution Circuit diagram Characteristic Device features Data

SITOP select fault diagnosis - rapid and reliable A&D SE PS SITOP select Automation and Drives The solution Fault paths are powered down reliably even under very poor operational conditions. Retension of the 24 V power for all other paths Plant down time is reduced or even avoided. Fast trouble-shooting and fault localization Loads with high startup current peaks power up with current limitation. Malfunction-free device startup The situation today The solution Circuit diagram Characteristic Device features Data

SITOP select fault diagnosis - rapid and reliable A&D SE PS SITOP select Automation and Drives The solution Selectivity and fast error diagnosis of 24 V feeder circuits Four feeder circuits (outputs) per module Each output can be set between 2 and 10 A using potentiometer. Multi-color LED for each output for rapid fault localization Potential-free common signal contact for fault diagnosis Several modules can be connected to a single power supply. Simple and rapid installation using standard mounting rail Additional line protection and gradual equipment commissioning with exchangeable FK2 blade-type fuse The situation today The solution Circuit diagram Characteristic Device features Data
