We have a system that has been installed over a year now. Normally when the generator doesn't run (due to mechanical issues), VRM will give out notification via the app and email saying Generator Not Detected at AC Input. We have the capability to remote reset the fault and generator will run, alarm goes away.
All of a sudden VRM doesn't give out notification anymore when the generator isn't running. (We have a third party device that give us the alarm as a backup)
Firmware version is 2.84 and no auto updates enabled.
Recently there are more of our installed sites that comes up with the same issue. The firmware versions are 2.84, 2.85 & 2.89.
Has anybody come across this and what is the possible solution?
