Vial PCM configuration error 7697A Headspace

Hello I have a problem with my 7697A Headspace Sampler connected to 7820A GC system.

After installing the tube from Headspace Sampler to GC system I turned the devices on and both of them gave me 'Not Ready' status. I've clicked Stasus and saw a list of errors: on the Headspace it was: Vial PCM fault, Vial flow limited and External device not ready. On the GC system status show: Not ready, and problems are Front detector flow, Front inlet pressure and Oven temp.
Can anybody give me some advice what should I do in this case?
I can only add that Headspace sampler was not turn on in more than a year - can that be a problem?

Thanks for all of the answers!
