This morning, Francesco went to WE Building to check the cabling on the Coil Driver box of SWEB.
All the cables looks properly plugged.
Francesco also checked the plugging of the Sub-D25 on the bottom flange of the mini-tower, plugging OK.
The Coil Driver box has been switch off around 8:06:50 for about 30 seconds or more.
The signals looks the same after switch OFF/ON.
The DAC that sends the current to the COIL has been reconfigure, also here no effect visible.

The DaqBox 43 connected to the coil driver box (SWEB_ADC_LC_LVDT_out, SWEB_DAC_LC_LVDT_out, SWEB_ADC_MONI0, WEB_MezzCam) has been switch OFF at 09:13:48 for about 45 seconds.
And then it has been reconfigured :
2023-02-07-08h14m36-UTC info masserot Reconfigure WEB_MezzCAM in SWEB_dbox_rack
2023-02-07-08h14m49-UTC info masserot Reconfigure SWEB_ADC_MONI0 in SWEB_dbox_rack
2023-02-07-08h14m59-UTC info masserot Reconfigure SWEB_DBOX_LC in SWEB_dbox_rack
2023-02-07-08h15m10-UTC info masserot Reconfigure SWEB_DBOX_LC in SWEB_dbox_rack
Nothing changed.
Then we reconfigured the DAC that sends the modulation line inside the electronic container:
2023-02-07-08h18m39-UTC info masserot process:SWEB_LC stopped
2023-02-07-08h18m51-UTC info masserot Reconfigure SWEB_DAC_LC_LVDT_in in SWEB_dbox_bench
No effect on the read-out observed.
Then we stopped sending the line to the primary coil at:
2023-02-07-08h23m27-UTC info masserot SWEB_LC saved - masserot: set the weigth for th lines at 0 (rev. 232506)
2023-02-07-08h23m28-UTC info masserot process:SWEB_LC started
We reconfigured again the DAC that sends the current to control the bench :
2023-02-07-08h25m54-UTC info masserot process:SWEB_LC stopped
2023-02-07-08h26m14-UTC info masserot Reconfigure SWEB_DAC_LC_LVDT_out in SWEB_dbox_rack
2023-02-07-08h26m20-UTC info masserot process:SWEB_LC started
Put back the modulation line :
2023-02-07-08h32m47-UTC info masserot SWEB_LC saved - masserot: set the weigth for th lines at 1 (rev. 232516)
2023-02-07-08h32m54-UTC info masserot 'Acl:Reload config' sent to SWEB_LC
Switch OFF and ON the modulation line again :
2023-02-07-08h38m23-UTC info masserot SWEB_LC saved - masserot: set the weigth for th lines at 0 (rev. 232517)
2023-02-07-08h38m30-UTC info masserot 'Acl:Reload config' sent to SWEB_LC
2023-02-07-08h40m41-UTC info masserot SWEB_LC saved - masserot: set the weigth for th lines at 1 (rev. 232518)
2023-02-07-08h40m45-UTC info masserot 'Acl:Reload config' sent to SWEB_LC
All the checks did not change anything in the SWEB_LC_LVDT_B/F/L/R_H/V_out_raw signals (read-out signals of secondary coils) that show a peak at around 7.8 kHz this morning, see plot attached.
