Well it seems you are onto something with the vme power supply. The issue has resurfaced and I did notice the LED's on the keyboard went out when the issue occurs. I looked at the power distribution board to the left of the vme and it shows the +12V

Tom, There are two power supply in the machine. One on top of VME box and other behind power distribution panel. The voltage that you see and check at PDP is not from VME.

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.

Ok; is this the 5a box located under and behind the pdp? I see now in the diagram it is labeled pdp1.ps1. Any suggestion for what to check to determine if the problem is the power supply or something connected to it? I noticed that when the 12v po

1. Palm down the GSM and open the safety cover to check input voltage +12VDC (at KDC2 3PL pins 2 to 3) and output voltage +5VDC (at KDC2 2PL pin 4 to 3) at the DC/DC converter. The DC/DC converter is located inside the control panel assembly ("Nose c

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.

Good calculation, i have to say. Do you forgot, If you let the machine cool down during night, the rest-temperature isn't roomtemperature? right, dont you think the temperature will be something about 140�C ??? heating up time then is not 3 hours. m

All, Does anyone sell a safe and effective way to connect a DMM to building ground via a power outlet? Personally, I'm comfortable using a banana plug, but the people that are going to be performing this task may vary in electrical understandin

The latest news. We ran another production run for 1-1/2 hours. The IP-1 gave a "memory NG" fault indicator twice after fully completing the first and second PCB's. We've been running the tray speed at 30% but noticed that the speed of the tray ro
