I have a special problem when my Siemens Simatic PLC switching on -Simatic T1435 CPU-its PWR -LED blinking and stopping after 10 to 20 seconds. What could be the problem? The application is water treatment

Just went through one of these on a big
web dryer. The power supply is failing.
The good news is that you can get an
exact replacement from Automation
Direct for much less than Siemens, about
US $700 and simply plug the CMOS
cartridge from the old unit into the new
unit and go. If anybody worries about
replacing Siemens with AD, Koyo is
who made the unit for them in the first
place.
