Thanks; I have a spare power supply coming as well. I will start by swapping dc-dc converters first and if the problem persists swap the pdp power supply. I'll report back what I find.

Yes, if I figure it out I will report back.

Thanks for the detailed information. I have a spare dc/dc converter on order to try swapping them. Another note is all dc power is cut out by the pdp.ps1, not just 12vdc. 24vac power remains.

The error in the attached picture(FCFF1043) is for 16 I/O card located in CIO slot one for board transfer. May be thats when your PDP supply drop voltage. If problem comes back, look at that card and/or connection and/or cable.

Thanks for the heads up. I suspect it is due to power dropping out to the IO chassis and other devices connected to the pdp. This is the first logicomm capture I have for it so I don't have other messages to compare it to. Machine has been running al

We have been running the machine for about a month after replacing the pdp power supply. We have not had a repeat of the problems since. I believe we can consider this issue resolved. Failing pdp supply was a known issue in the uic kb.

Check Power Distribution Panel Power Supply. No output or output too low for 24V, 15V, and 12V. Also, LED's on PDP LT6, LT7, LT8 , LT9, LT10, LT11 don't turn on at all, even though all fuses test OK for continuity.

I believe I found the power supply you refer to on the back side of the pdp mounting panel. I will have a look at it.
