Hi Rollon, thanks for your answer. At this point it seems that cold-start current surge, because the presence of large value capacitors in the power source, exceeds the sensitivity of the protection switches rather than a malfunction. Nevertheless, i

Hi Marcelo. I have used 2 non EU model 4C machines since 2002 that do this almost every time from a cold switch on. My local Tyco tech guy said that they all do it. They are still going after 12 years. I have another EU machine that does the sam

When I turn the machine on, almost every time I turn the Motor Power Switch it trips. I must to put the lever down and raise it again, then every runs normally. I asked to the former owner about that and told me that this machine always did it so and

My own unit has an internal transformer also. It has multiple secondaries, and a divided primary which can be configured to the required voltage by changing jumpers. Best regards.

Hi Marcelo The two machines I mentioned are the American type but they have an internal transformer fitted to convert from 110 to 220 Volts for U.K. Incidentally only one of the machines does it on a regular basis whilst the other one is mostly O.K

I have to design a power supply which converts 220V AC into 5V smothed DC. It has to be very small, so it shouldn't have a big transformer. Has somebody a scheme of a circuit? Thanks

You need switch out the cognex vision card.

First switch on after the holidays and this year it's the Dek265 playing up. On switch on, the screen comes up with "motor comms failure, card 0 axis123 " . On looking at the cards there seems to be a power feed missing ( see attached pict

Hi Is there any standard or requirement to test the solder under high power operation? For example, a power switching device, what is the failure mode of the solder joint after the whole equipment undergone a high power (current / voltage) environmen

DEK_265LT had been turn off and on by itsefl couple of time yesterday,and then off for good. I check the power going in to machine to the switch,got power to it,then power out to that little green box but there wasn't any power out put from that lit
