I guess one reason we've had so few alarms lately might be that the alarm handler was not running! The alarm handler MUST always be running. That's an absolute must. And it should be "always on top" and "visible on all workspaces".
Anyway I started it and checked to make sure we had decent alarm limits set. Some were missing, like on pressure, and the vacuum. I set those. I saved the file to ./ALH/atarg_cold.alhConfig.
