Allen Bradley 150-F60NBDD

[Fellow 0]

I have a Allen Bradley soft start 150-F60NBDD. I'm getting a Fault 46# ( V Control F46 • Sense of control voltage in error ) .I replaced caps, checked ICs, and relays with no positive results. If there is any info on this fault or how to resolve this issue please help.

According the fault code description, your internal control voltage is staying too low for too long after the contactor closes. Check that your line power is within guidelines and evenly balanced from phase to phase. Check your grounds as well, as stated in the troubleshooting section of the book you attached. If you're still having the problem,  I would see about finding a place to measure the actual voltage. If it's actually low, figure out what's pulling it down. If it's not, replace the control module.

Hope this helps.
