Re: CompactRIO not powering up?
A lead-acid battery at 10.8V without any load attached would indicate a relatively discharged battery. Even when mildly-loaded, the 12V MK battery should stay above 11V for quite a while.
As Eric VanWyk alluded to in a previous email, a discharged battery can result in the symptoms that you've described. The 24V boost converter only works down to about a 4V battery voltage. If you've got a discharged battery, the converter might work fine when the cRIO isn't attached but, upon attaching the cRIO, the supply might struggle to boost if the battery droops further to account for the extra load. I hope that you opened the PD instead of the cRIO. Why are there metal shavings in your electronics? (insert yet another reminder to teams to please stop doing this...) Russ |
