#91040 - Update - ESD Problem? Responding to: ???'s previous message |
It seems that either my particular RC reset or the S52 may be more susceptible to ESD, or the combination of both. My application is a cut to length machine for webbing straps, etc. I have new input from two sources that say cutting velcro and it seems to generate considerable static, causing resets and strange behavior. Other materials that do not generate static work ok, machines with the C52 are ok.
How can I simulate or generate static and test my theory? Each unit that has had a problem in field shows no symptoms at our facility. I read a thread here once where either Craig or Steve used a BBQ lighter and modified it, but I can't find the thread again. Thanks Jon |
