Communication failure of HPLC 168 Detector component

[KUDU]

Hi everyone,
I am using a Beckman System Gold HPLC comprised of 508 autosampler, 126 solvent module, and 168 detector. It popped out a service message and stopped running a sample midway. The messages were " High speed communication of detector 168" and "Communication failure" . It then initiated a download of microcode and completed. The machine became fine but i stopped running the samples and switched it off . I am scared similar thing might occur and damage the machine or maybe i did something wrong.

Please i need advice on what to do and thanks in advance .

O yee of little faith in yourself! You fixed it! It was the computer. Turn it on and start your sequence.
