SM52 flashing symbol meaning...?

Hey there everyone...recently put in charge of an Sm52 with a console design I'm not familiar with. Speedmaster comes with several console options like KID ZID & CP2000 etc. In the pic provided I'm being prompted by something to do with fountain supply *me thinks ??? The pressurised tank is full, the fountain tray sensor is working & at normal level So.... what is this trying to tell me. Btw... it hasn't interrupted print production. It goes into the print cycle just fine. Its just that I'm curious about what it means?

 

The water or press wash tank is low

 

I think you have the earth cable issue ,
