Hello, i get unusual high signal on FID on 7890 and this message
"Front detector - Fault high voltage error"
What is happening? There is some part I can try to replace before call a technician?
Thank you
Hi GeorgiaDean were you able to solve your problem?
In regards to the FID not lighting, be sure to refer to the Troubleshooting an FID not igniting article in the Knowledge Portal.
Dear Community
We faced problems with our GC 7890B which is connected to a Leco Pegasus BT. Since this week we have a really high noise, which comes regularly every 5seconds. We already cleaned FID many times, replaced Jet and built the FID out an in…

I think our only problem at the moment is a hardware issue (EPC failing to shut makeup gas OFF when called for) that prevents FID ignition… we’re putting in a call for service to resolve that. I’ll be working to resolve user error (Comments Edited by…
Hello,
Are you sure the end tip of the PLOT column ends up (and 2 mm withdrawn) inside the FID Jet?
Any problems when igniting the FID?
FID Jet could be contaminated from PLOT stationary phase particles ..

Hi
When FID is off means no flame.
Voltage applied during ignition and while FID OFF so ignitor also Off..
When ignitor off then voltage also off...
Hope, it's clear to you..
