Your 90-30 has 17 different CPU modules, so you’ll need to check the fault tables identify which one is responsible for the outage. This is a problem that’s likely the result of a hardware failure in your CPU module. If the LED is out, you’ll need to replace the CPU.

We’ll talk about how to do that in this post. Since the 90-30 has eight distinct modules for power supply, you’ll need to consult the diagnostic fault tables to determine which one is causing the problem. If there’s no light at all, you’ll need a battery to keep the program running while you change the power supply. When the light is green, your supply is in good standing. The Power LED is indicative of your power supply. Here’s how to tell the health of each of these indicators with the help of your diagnostic fault tables. There are four LEDs to check-PWR, OK, RUN, and BATT. These will be on the front of your power supply. The first place to start is checking your LEDs when it comes to locating the source of the problem with your 90-30 PLC. So what can you do to prevent power failures in your 90-30 system? Here’s how and what you can do to prevent it and diagnose the problem after it’s happened. When you have a legacy system such as the 90-30 series from GE, understanding how to handle these common problems can help immensely. Keeping your PLC running is of the utmost importance on your factory floor. Although fatal fault errors are obvious when they happen, other problems may be less noticeable until they get worse and impair system operation. Regularly checking your diagnostic fault tables can help you catch issues before they become larger problems. One of the most common problems we see at Qualitrol with 90-30 machines is CPU and power failures.
