Hard wired
Hi all
Y-D starter shouldn't go through the PLC .specially if the operator have a manual mode of operation .in this mode he definetly should not go through the PLC and use the hard wired interlocks and timers in the same time i agree with the guys who said that it's a sefety issue to use the hard wired interlocks and timer because even the interlocks stucked the operation is still safe.in the same time we will save in PLC I/o's
