surprising problem sp20???????
hi,
i have used the mini sp10's and sp16's and now when i come to use the mini sp20's i am confronted with this craziest problem i have ever faced. not sure if the plc has bombed cos i am facing the same problem in two different sp20's.
when i turn the power supply by turning on the key switch all the output contacts are closed. i cant beleive this. i tried this with both 110VAC output and 24Vdc output. but surprisingly when i checked for a short between the output and common i found none.
can somebody help me please!!!!!!!!
thanks,
