Hi all,

Would appreciate any thoughts.

Lab 11 had a low humming sound, no real sound other than that and green light stable. Stripped down and appeared to be coming from pcb 35 ICE amp. Swapped this for a new one and all working for 3 hours then same thing has occurred. Hoping this hasn't damaged new module but struggling to think why this would happen.

 

Cheers

Jonnie

I’m sure you’ve already considered this, but are you using the correct powerlink cable version? This will definitely cause a hum if you use the incorrect version
