Our TC/EA was shut down for a few months and I was restarting it today and I keep on having this 1999 warning from the Jumo Temp. Controller. It appears to be related to carrier gas flow (perhaps the safety switch is too sensitive), but I am not sure.
I can set the temp. and then everything seems fine, then if I leave on a flow meter for "too" long, I get the 1999 warning. However, flows are fine. And the system has been leaked checked (and checked...).
Is it possible to just lower the carrier gas safety switch setting to a less sensitve level? Is anyone else having this problem with the main reactor heater controller?
