Remarkably this is now 2020 and I looked back and this puppy is still closing away pretty reliably. For the record i have added an uninterruptible power supply 1350 VA, which is overkill. Probably could have used 900.
I looked at the settings and it would be nice if this thing closed if it lost Communications, but I do not see a setting for that. Windows 10 screwed up again and rebooted my computer late at night and roof was open. I thought I had turned off updates....
Happy New Year!
