Hi Sir These alarms occur during booting when the machine is powered ON, The control is 840dsl and PCU50.3 siemens Sometimes the machine will not properly turn on until these alarms are cleared, Why are these messages appearing and how can they be removed? Although other machines do not have these alarms during booting period, they boot straight away. I will be very grateful if you can give me a guideline M Shafay Attachment123.zip (174 Downloads) |

HI Sir Thank you very much for your response 1. PCU 50.3 installed in machine 2.This is new one machine, we purchase before 6 month ago. 3.I had the NC and PLC of the machine re-load (restore). I am not sure may be these alarms are triggered after the machine NC/PLC archive is restored. Before restoring may be these alarms not present. 4. NO UPS installed. Only AVR installed,The machine is being powered through AVR 5. Input AC power is good, no fluctuation in power source, 6. Machine ground is good less than 4 Ohms 7. Physically communication cable connectors are good. 8. 24 volts are directly connected to NC and PCU 9. How to checked Capacitors of NCU and PCU , are inside the module. 10.I will post a picture of PCU50.3 7 Segment LED status. Your guideline will be greatly appreciated by me Rana Shafay Attachment234.zip (161 Downloads) |

Hi Sir Piscean Bundle of thank of your valuable and quick response. After repairing of PCU power supply and Main PCB now machine is working fine, I checked the machine, Yes sir you were right there is a UPS being used inside the machine. Various alarms were triggered when the operator did not shut down the machine properly. So I have instructed the operator how to shut down the machine properly.
