Cooling fans on l370mw

[Cris_co]

I just got an l370mw, and the cooling fans always run on the hydraulic units, even when it’s in power save mode. My mcv4020 shuts everything off when in power save mode. Is there some parameter that changes this? I’m not a mass production shop so my machines see a good bit of idle in between runs.

Perhaps you have a faulty relay or contactor, ie stuck on?
Alternatively, it would be easy for an electrician to wire in a relay for the fan to drop out in power save mode, or drives off.
