Quad 4C power switch

Quad 4C power switch | 7 August, 2013

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 did not give importance to this.

I don't agree about that,I think it's a symptom of wear that wil cost me expensive in the future.

Has somebody experienced this phenomenom? Since this machine is in Southamerica it is configured to run on 220Vac 50HZ Thanks.

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 same thing only you have to open the front to re-set the trip !

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, it is not a proper mode of functioning. It is just a matter of time that it might cause any damage to the power source or a controller card (or not, it is a random possibility). Does this phenomenon also occurs in American units 110V/60Hz?

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.

Other than that I believe the machines are the same. I agree with you that it is not really desireable but it seems to be an accepted error unless anybody knows different.

Kind regards Rollon65

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.
