Testing Multiple Physical Outputs

Topic Progress:

It is really easy for a design engineer to incorrectly program an output and unintentionally disable a relay, which could go undetected for years until it fails to trip during a fault.

These videos will show you how to create and/or modify your test plans to test multiple outputs at the same time to help make sure that this relay does EVERYTHING it is supposed to.

We can’t use their products without express permission from them, even if we rented or purchased them.  We’ve been trying to get that permission for years but no-one seems to know who we should talk to, or they don’t return our messages. At this point, the only hope is for you to contact your local Doble rep and ask them to contact us to participate.

Megger Test-Sets

We contacted Megger to see if they wanted to participate and they said that they need approval from the higher-ups before they could send a test-set. Please contact your Megger rep and ask them to contact Greg Valdez (Megger’s Marketing Communications Manager) to see if we can add them to this series.

Don’t see your test-set in this series? Leave a comment below and we’ll see if we can get a demonstration unit and add a video for that test-set.

Would it be possible to get copies of the plans you used in these training videos for the Omicron? I would like to go through them and see how you made them which is a bit hard to do from watching the videos

It doesn’t look I saved after recording the video. I quickly mocked up the “51GT 2X” test in this file, which should be pretty close to the settings in the video.

Hope it helps.

When the outputs are put in series, I believe OUT5 is connected incorrectly. I believe the polarity is backwards and the contact probably appears “closed”, so the test is really only testing OUT1.

I can see how you could make that determination when looking at the video.

I spent a lot of time making sure I got the right combination when testing the relay because it didn’t work correctly they way I though it should have. But I may have documented it incorrectly. Different relays might operate differently depending on their internal circuitry.

Always test your connections to make sure the connections are correct.

The test for this circuit would be to pulse OUT1 for 10 seconds and make sure you don’t see the contact close. Then pulse OUT3 before the 10 seconds expires and make sure you see the contact close.

Do the same test by reversing OUT1 and OUT3 in the previous test.
