The injection syringe hangs over the HDX-2 injection port and never injects - WKB11918

Article number: 11918

SYMPTOMS

  • The HDX-2 automation PAL arm hangs over the injection port, and the injection is never triggered
  • All the inject start cables are in the correct position
  • The event triggers are on in MassLynx
  • All positions are taught on the CTC-PAL3

ENVIRONMENT

  • HDX-2
  • MassLynx 4.1
  • Xevo G2-S
  • Chronos

CAUSE

The inject start command in MassLynx is different than the command in Chronos .cam method. 

FIX or WORKAROUND

Use the attached HDx_Waters_Online_Digestion_Xevo_G2_S.cam. This contains the proper code Key Value and MassLynxStatus for step 95.

ADDITIONAL INFORMATION

The online digestion method is written for SYNAPT G2-Si. The inject start command is "waiting for injection". The inject start command for a Xevo G2-S is "Waiting for inlet start 1". This is changed in the Key Value and MassLynxStatus lines for line 95 in the online digestion method.
