Afternoon! Hoping someone has experience working on the ABB gear below.
It’s in a Mobile Office/ Welfare unit, supplied via either 230v hook up or Generator with a Change over relay.
The issue is the 230 supply isn’t being able to be utilised - only the generator. Then occasionally the 230 supply will kick in but as and when it feels like it.
We’ve change the main relay ( ESB-40-22) and secondary 12v relay ( EH-04-11) which locks into the main relay and this hasn’t helped.
I’ve got next to no experience with a board like this so hoping someone can be of assistance.
Any help is appreciated and sorry if the detail isn’t enough but i can go into it more for anyone who understands.
Thanks
