Hi, I recently obtained an old Ungar 4700 smt rework station, but have no information about the thing. Does anyone have or a source for info (and parts) about this machine? It powers up, lights up, gets hot, but I have no nozzles or any accessories.

Manually move the beam away from the limits with the power down. Be sure the beam is parallel (marks to help with this are on the Y-axis lead screw covers near the machine front) and then power up again. Good luck.

We have 3 1818's running in our shop. The only hookups we have are air regulated to 85psi, vacuum and power. The machine will not power up with air less than 40 psi.

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

If the above recomendations do not help...(I'd try them first) Did you try the infamous "Fuji Fix"? Power the machine all the way down and power it back up. (Rebooting the software)

We are looking into adding an Uninterrupted Power Supply to our MYdata's pick and place, to protect the PC from power surges. I am looking for recomendations from current users. Thanks in advance.

Hi, Some idea for you to troubleshoot: *It could be the motor problem,check all motor power,after ON power to m/c,the motor should be engaged. *stepping driver spoil

I doubt that will do anything. You have had the board powered down and powered back up, right? This will have the same effect. But hay, what have you got to loose?

Power up the circuit, and see how it performs. Check voltages at the input and the output, and compare to a known good board. Otherwise, you can check resistance in an un-powered circuit. Compare the readings to a known good board. cheers, ..rob

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.
