I do not think so : you solved the Acrobat problem and I now have the "Correct Baldor Schematic".but how things work is beyond me.
Change that to : Same with Integrated Circuits, I read that they are made up of hundreds sometimes thousands of little transistor mini switches.Same with transistors, I read they are made up of hundreds sometime thousands of little mini switches
Now you know that you can connect it to the +8_KEY supply. Just make sure you do not exceed the maximum current rating of 725mA.I am using this on a metal cutting lathe and was adding an rpm readout which needed a 6volt input for power. I was testing to see if there was a 6-9 volt
Where did you connect the negative probe of the meter to take those readings ? You should have zero volts on the source of the transistor and 350 volts on the drain.Im still getting 120 volts on each leg of the transistor and when I check DC- to DC+ I get 350 v
The 350v implies that the voltage is 230v.Ya the tag says 230v but the place I got it from has it to run on 120 v
Here ya go:https://workspaces.acrobat.com/?d=1m...2LUgIisNy5sZHAIt's difficult to suggest a replacement without seeing the schematic.
A 9v battery and potentiometer will work fine.As far as a variable dc power source, whats a good way to go? Something I can grab at RS? Could I use a 9v battery with a potentiometer?

Have you tried to contact Baldor?

Not you but a bad girl.Im confused, something I did?
Make sure that the power is disconnected and all capacitors are discharged before you perform this test.
500k is too high to use. Instead, just connect a diode in series with the 9v battery :
[9v battery +] ----->I--- +8_KEY. (--->I--- is the diode)
[9v Battery -] to GND.
You should get 8.4 v with this arrangement and the diode test meter connected to pins 4 and 5 of the optocoupler should show continuity.
