Hello, first post here. I am thus far unable to get my AIPM power monitor to read the current transformer (OPTOEMU-ACT-0750-050, 0.333VAC secondary) to monitor a 110VAC power supply, following the wiring diagram on page 11 of form 1453. Point 0 reads line voltage just fine, point 1 reads 0 (points 2 and 3 read 0 as well, of course).
Using my trusty DMM I can measure AC voltage coming out of the CT as it should, but as soon as it’s connected to the AIPM field connector the output drops to 0 in PAC manager, control, and on the DMM, regardless of CT lead polarity.
The data sheet is a little murky about exactly which CT to use; the diagrams mention a ‘typical 5A CT’ in a couple places and ‘0.333 secondary CT’ in others (e.g. 3 phase). Do I simply need a CT with current secondary to measure line current with this module?
Thanks in advance,
