XGM status 21.4.2017

During Easter break, the two XGMs in the control system (XTD2+9) had no issues.
XGM@XTD10 however had an issue: tuesday morning it was found that all pumps had stopped. The scroll pump showed an error. UPS apparently had excess load sunday evening 19h30 but couldn't send email (network error). Possibly vented with tunnel air up to 10mbar since that time. Investigation is ongoing.

Thursday enabled DOOCS pressure reading of XGM in XTD10, UPS rechecked

System surveillance on coming weekend: Jan and Theo 1 day

Other remarks:
- WP74 staff have received their dosimeters for ZZ access if required
- some automatic monitoring and info system is needed soon, e.g. karabo to NAGIOS connection
