	Hi, I am in the process of commissioning a micom P443 device. The opto inputs are now confingured but when I activate any of them by applying a DC Voltage, the status in display does not change. I expect the status to change from 0 to 1 according to the configuration but this is not happening. what could be wrong here?

	How much current flows? A nominal current flow for an optocoupler LED is 10 mA. __________________ "Don't disturb my circles." translation of Archimedes last words

	Generally for the inputs source of DC voltage is taken from the relay. If input is given from external source , both positive and negative to be connected to the relay.Therefore check connection. __________________ Ramesh,Freelance Electrical/automation Consultant
