Per the VE.Bus BMS manual, the pre-alarm becomes "high" in case of imminent cell under voltage.
My Question: When does it drop back to free floating? And is this return to free floating adjustable?
I am considering using this signal to trigger an Onan generator start pulse via programmable relays on my Quattro 5kw. Thanks!
From VE.bus BMS manual:
Pre-alarm
The pre-alarm output is normally free floating and becomes high in case of imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell). Maximum current: 1A (not short circuit protected).
The minimum delay between pre-alarm and load disconnect is 30 seconds.
