issue with DBox 169

The DaqBox 169 named "WEB_DBOX_ADC1" does not work properly since March 21 18:00. The mezzanine ADC in slot 0 "WEB_ADC_MONI3" does not work. This mezzanine has no +12V power supply anymore.
Some signals of mezzanine ADC in slot 0 "WEB_ADC_MONI0" also show a strange behavior.

Today I deactivated the mezzanine in location 3 because there is a large current consumption on the -12V power rail due to the lack of +12V.

The problem could be due to some animals dropping on this DBox...

We will change this DBox during the next maintenance shift.
