Has anyone else run into this cryobay failure on
a Varian system? I found today that the cryobay is no
longer reporting values for Exhaust(psi), Inlet(psi)
and Cold Loop Impedance. All of these now report NaN.
Oddly, the cryobay reports the temperature at a stable
25.0 K and that heater current at a normal value. All
of the stages report their values normally as well.
I see the following in the log section of the software...
Error -10401 occurred at AI Clock Config.
Possible reasons
NI-DAQ LV
The specified device is no a National Instruments
product. The driver does not support this device.
I am assuming this means the National Instruments
board in the cryobay has gone bad and needs to be
replaced. I also am assuming that we are okay to
keep running in the interim. Thanks in advance for
any information and advice on this fault mode.
