Hi Peter,
The hv_frontend should set the current limit to some high values.
There is a hardware limit on the front of the crates which I think
overrides the software limit. I was also using 0500 for the eSC based
empirically on the roughly 430 current that was drawn. The software
current limits should also be settable keys in the ODB. Under
Equipment/HV/settings/ , you should be able to find a set of current
limit keys. We'll have to set the hv frontend to use these values when
first initializing the crates.
Perhaps Peter can comment on the neutron channels, but I would
probably just see what type of current is drawn on them right now.
Best regards,
Brendan
