There are pots on the board in the power supply to adjust the voltages after the machine is powered up. The location of these pots are in the munual supplied with the machine

Got it powered back on Friday.... We did check the UPS (power-supply)and indeed it was bad. So we referenced the manual and found you can bypass the UPS all together. So we just directly plugged the machine past the UPS. Well the machine is running b

If you have a UPS on your machine there should be auxiliary contacts in the main breaker switch SW 1. These contacts tell the UPS if the main rotatary switch in turned to on or off. If the rotary switch was set to off the UPS knows not to turn on i

Now I have to guess and make a few assumptions. Without looking at the back side of the board my guess is you have some 400-100V diode bridges before the resistor ,zener and the FET . The FET is a 500V 0.85 Rdson NFET. All of this suggests a chopper

I currently have a board that has several wires that need to be soldered into it. Many years ago I remember wave soldering power supply boards that also had many wires. In order to keep the wire insulation out of the solder fillet and keep the wires

Hi, we do Sn plated I/O pinning insertion into Ni/Au thru' holes. no problems here so far, as we cater for the "interference" (fit-allowances) of the I/O pin into the thru' diameter, via improved PCB thru' hole designs. before this cater/considerati

We are using TL431 in our most of the power supply circuits. Recently the power supply board is returning from the field due to TL431 component problem. Could you people, please suggest me what are the possible reasons for TL431 failure & trouble sho

Hi Deni, Thanks for your interest in my problem. It turned out that the power supply to the VGA vision board (the system in the black box)was faulty. I replaced it with a universal PC power supply and all is well.

It could be a blown fuse on the power distribution panel or a failed power supply. Check the power distribution board in the front lower center of the machine. There are 11 LEDs on the board and 10 should be ON
