EX BT Ionpump Gauge restarted and caused VACSTAT alarm
At 10:11 the EX BT-Ionpump gauge came back to life, causing a VACSTAT ALARM. This gauge has been flat-lined since yesterday, 07:09 Fri23Jan2026.
Could be because today is a sunny day after a long period of cloudy weather (the EX_BT system is solar powered)?
At 10:18 I restarted VACSTAT to clear the alarm.
