You might try checking to see if the float switches are actually lifting up with the water level, I have seen them get stuck in the open position. Also check to see that the solenoid valve is actually sealing off (closed)

Don't know about Topaz, but on Essemtec machine using SMC ejector, there are separate solenoid valves for vacuum and release. The connectors are identical and side by side. If these connectors were swapped then I would have the symptoms you describe.

I only have first-hand experience with 2 pick-n-place machines, but both used a small pressure puff to insure part release. I haven't seen any software settings for this, but a small solenoid valve was dedicated to the operation. I recommend you look

Jim, It's been a long time since I worked on one of these so this is going to be a general idea as to the issue. There's a solenoid valve that is controlled by the E-stop ckt. When in E-stop in stops air from entering and vents the pressure lines

The problem you report is very uncommon. Nozzles falling out of the placement heads can only be caused by severe mis-adjustment or failed parts. The following items should be checked: 1) Nozzle position hooks (on placement heads) 2) Clutch solenoid/

Brian, We've see foaming issues with our wave flux occasionally when running large slugs of product through the wash. We love the wave flux and changing it was not an option. Our process parameters for the wash machine we're derived via a validati

Just a little status update. When it's running and I monitor the I/O, the mount vacuum bit never turns over to 0. It may be turning over enough to run, but not long enough to see on screen. It stays at 1. When it errors, I can trip it by putting my

At this point all the sensors, switches and solenoid valves were checked. Their electrical signals and actions were phisically checked at the I/O cards level (Panadac 783-065 and 065A). Above mentioned signals were monitored from "I/O Monitor" functi

There should be a regulator to adjust the puff off on the inside left back panel. Remove the left side cover to get to it. Write down what its set at prior to adjusting it. I have also seen this problem caused by water in the system. Make sure that y
