fi bre sensor I/O unit ARC-EL3/2.0 front panel
1. Connection for portable arc sensor (ARC-SM)
2. Programming switches (factory setting - all DIP switches in „OFF“ position)
NOTE! The confi guration of the DIP switches must be done properly before operating the system!
3. POWER indicator light, indicates that the supply voltages of each component are in order.
4. COM indicator light, lit when the master units and I/O units are communicating.
5. ERROR indicator light, indicates an internal fault detected by the component’s self-
diagnostics. Such faults include faulty arc sensor or changes in the amount of sensors.
6. Connector sockets for the modular cables
7. LED lights indicating sensor activation
8. Terminals for three fi bre sensors
9. Portable arc sensor ARC-SM connected and operational
10. Portable arc sensor activated
11. I/O unit trip relay activated
12. Terminal block for external communication and BI/O channels and trip signal
