SITOP selectElectronic Diagnosis Module Fault diagnosis – rapid and reliable
Blow the whistle on plant downtimes • Keep the overview of your 24V load feeders. • Show the red card to downtimes caused by faults
The situation today Circuit diagram of the power distribution for selective protection The situation today The solution Circuit diagram Characteristic Device features Data Power supply, e.g. SITOP power Drop in 24 V ! + ~ 24 V = – 4A 6A 10A 10A Load 1 Load 2 Load 3 Load 4
The situation today • 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
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
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

Switching characteristic • Irated can be adjusted from 2 to 10 A per output circuit. Characteristics per current • requirements depend on the output circuit. • From 0 A to the set value ( I/ Irated=100%) without switching off • From set value up to 130% switch off after approx. 5 sec • Above 130% of set valuecurrent limiting to 130% for 50 to 100 msec, next switch off • Over the set value with simultaneous collapse of the supply voltage below 20Vimmediate switch off The situation today The solution Circuit diagram Characteristic Device features Data 100.0 sec 10.0 sec 5.0 sec t 1.0 sec 0.10 sec 0.1 sec 0.0 sec 0% 50% 100% 150% I / I rated
