K1/K2 relay NC/NO not "normal" ?

Hi Everyone,


We are using the K1 relay to start our generators. The generators require a "closed" connection to start. We connected to the NC and COM points of the relay, programmed the Quattro to close the relay for generator start on <10% SoC and stop at >80% SoC.


This how ever seems to be the other way around. Even a "dead" victron (no AC/DC power) has NO "closed"


I have checked and there is no easy way of monitoring the relay's in the Venus, what am I missing here ?


Thanks

If your generator need a closed contact to start you have to use COM and NO (normaly open) not NC (normaly closed). T

In my mind it should be NC (normally closed) so that the Victron has to put effort into keeping it "open" - no ?


(It guards against something going wrong inside the Victron and it's logic failing, causing the relay to go to it's powered off state of NC?)
