Happy New Year!
Does anyone have experience with the Basler BE1-50BF Breaker Failure Relay that has the Control and T1 timer pots and test points on the front of the relay? There are no timer setting wheels. I called Basler and it appears I need an oscilliscope to set the timers. However, with only one BFI input, supervisory option not installed, I am trying to sort out a testing method. Basler application engineer only said things like: tricky, complicated and sensitive.
200 ms control time
80 ms T1 time
BF1 contacts w/target
BF2 contacts w/target
1 Amp current pickupNo Instantaneous Element
Publication: 9190600990 Rev. F 09/07I would appreciate any test plans, notes and suggestions. I am testing with a Doble F6150 CPU1. Protest ver. 2.09.
Thanks,

You’ll likely end up pulling out your hair if you try and use those test points. Treat it like any other 50BF relay.
Apply 1.5 amp and make sure the trip contacts do not close
Apply the BF initiate signal and make sure both contacts close.
Keep the BF initiate signal on and time both contacts. Adjust pots to get the time you need.

Thanks! I will let you know how it goes.
It is also important that the switch positions on Page 2-3 of the BE1-50BF manual are in the correct position. If you look at the logic diagram on page 3-1, you’ll see that the relay will not operate at all if switched 4,6,5,8, and or 7 are in the wrong position
