BCU39 still not working.

We decide to remove box39 from AGW frame.

Box39 unmounted, we found a defect in the connector of the power line of the BCU39.

PIC controller updated in order to enable the linear power supply switch on and off.

BCU39 power supply connector repaired

BCU39 now is working

Pupils on CCD39.

LC traslator disconnected and reconnected. Now both axis are working

ADC functional test OK (dispersion amount and axis)

Overtemperature protection test: OK (all devices powered off, including linear power supply) when temperature > threshold.

CCD39 RON TEST

Devices powered off: all flowerpot, ccd47, filterwheels.
