Dear All,
I had face a strange problem over a week. I have an evaporator system that stop by itself 2-3 times in a day. The evaporator system had been installed and running for 2 years. The system run 24 hours in high volume so this problem is causing me a big time. I had tried several method to solve the problem, but I still unable to find out the root cause. Please advice what are the most possible cause that can stop the system. Below are the symptom and action i had taken. Also attached the machine system layout for your understanding. Thank you.
Symptom:
1. Evaporator System stops immediately.
2. Versa View Microsoft operating system reboot by itself.
3. PLC RSLogix go offline by itself. Note that PLC ladder monitoring normally in online status, for technical trouble shooting purpose.
Action:
1. Changed new Versa View Industrial PC. Clean up the hard disk. Install anti-virus and ensure operating system is healthy. Remove any bios that can cause the PC to reboot.
System still stops once in a while. PC still reboot by itself.
2. Disabled PC Anywhere remote control. Only use versa view as sole control.
Symptom still happened.
3. Temporary bypass E-stop circuit. E-stop is the only control that can execute sudden stop to the system.
Symptom still happened. It is confirmed that E-stop circuit does not cause the sudden stop to the system.
4. Turn off Versa View Industrial PC, power plug remain connected in the panel. Reinstall Remote workstation PC software to take over sole control of Versa View PC.
Another symptom happened. Versa View Industrial PC reboot by itself without turning on the switch. Though this PC is now not in operation. The steam valve just shut down itself and cause problem to the system.
