ESI source not recognized when switching sources on a SYNAPT G2-Si - WKB10126
SYMPTOMS
- The ESI source is attached, but MassLynx does not pull up the source options
- Cannot put the instrument into Standby mode
ENVIRONMENT
- SYNAPT G2-Si
- MassLynx 4.1
CAUSE
The electronics are locked up.
FIX or WORKAROUND
Do an electronic reboot:
-
Exit MassLynx.
-
Flip the pump override switch to the down position. (This is the top toggle switch, above the breakers.)
-
Flip the EPC and Aux breakers down.
-
Flip the Electronics breaker down.
-
Wait a minute or two. You can then reboot the host PC.
-
Once logged in to the host PC, power-cycle the ACQUITY before proceeding.
-
Flip the Electronics breaker back up. (At this point the PC must be on and logged in and the ACQUITY must be on.)
-
Wait one minute.
-
Flip the EPC and Aux breakers up.
-
Wait for the EPC to boot up. (The flashing white/purple light on the SYNAPT G2/S/Si will stop flashing and remain steady.)
-
Wait just a bit longer.
-
Go into MassLynx.
-
Open the Tune page
-
Check the vacuum (View > Vacuum > Vacuum tab). Make sure that you have real vacuum readings (not 1e-8 for the Tof vacuum). If you don't have a real Tof vacuum reading, start the reboot again.
-
Once there is good vacuum, flip the pump override (toggle) switch back to the Auto (up) position.
-
Put the MS into Operate mode.
