       working OK
     
      DSSSD bias & leakage current OK - attachment 10

System wide checks OK - attachment 11-15
       note global clock status 6 errors reported earlier today have now gone

FEE64 temperatures OK - attachment 16

18.38 Transition to safe state

DAQ STOP
      disable data transfer 1
      detector bias OFF
      FEE64 power OFF

Can restart as follows

1) FEE64 power ON
2) DAQ RESET
3) DAQ SETUP
4) Enable histogramming
5) Enable waveforms
6) Detector bias ON
7) Restore ASIC settings
8) ASIC Control
9) FEE64 temperatures
10) System wide checks
     sync ASIC clocks
11) FADC control - calibrate ADCS for *all* FEE64s
12) System wide checks contd.
13) DAQ GO
14) Check ADC data item stats
15) Check WR timestamps

If all OK can re-connect to Merger/TapeServer as follows

1) DAQ STOP
2) enable data transfer 1
3) DAQ GO

Can disconnect from Merger/TapeServer as follows

1) DAQ STOP
2) disable data transfer 1
