ENV_MBC_CURR sensors are now working again, we suspect of a bad contact on the board power supply line (+/-15Vdc). To be monitored in the long term.

Attached the tipycal signals for IPS and UPS current (first plot); worth noticing that for little current values there is an offset (see as example ENV_MCB_UPS_CURR_R) that can be removed in datadisplay with the NO DC option (second plot).

Note also ENV_MCB_UPS_CURR_T that is very rich of odd harmonics (third plot).
