  1. Hi, I am Md Firoz Mortuza, Senior Scientific Officer, Bangladesh Atomic Energy Commission. We have been using SLC 5/03 CPU to operate our Control Panel of Cobalt-60 Gamma Irradiator since year 2000. For few days, it is not operating properly and we can not run our irradiator. The detail scenario is given below: On the Power Supply module RED LED is ON which is normal. On the CPU module, 1. 'RUN' - LED is not Green. It is off. Normally, the LED light is GREEN. 2. 'BATT ' - Red LED is OFF which is normal. 3. 'RS232' - Green LED is not flashing. 4. DH 485 - Green LED is flashing 5. FLT' - Red LED is ON. It is 'blinking'. This is what we have not seen before. The selection switch on the CPU module is in 'RUN' mode. All the lights are off in the OUTPUT modules whereas desired lights of input modules are on. Normally, both the INPUT and OUTPUT module lights remain on. I have attached one photo for your easy understanding. Please give me your comments and suggestions to solve the problem. Thank you very much. Regards, Md Firoz Mortuza Senior Scientific Officer, Gamma Source Division, Institute of Food and Radiation Biology, AERE, Bangladesh Atomic Energy Commission.
