[Solved] Brake output setup and test out1 & out2  



I have 2 eddy current brakes connected, through LSA-H3P25YB units, but when i do a break test, only Out2 i putting out PWM.

Both brakes are buzzing in output mode, when there a connected to Out2. But not Out1

Break 1
LSA-H3P25YB Com -> YourDyno Out1 0V
LSA-H3P25YB Pwm -> YourDyno Out1 OutA

Break 2
LSA-H3P25YB Com -> YourDyno Out2 0V
LSA-H3P25YB Pwm -> YourDyno Out2 OutA

I also seem to have the same problem with the no show  "Control brakes independently" on some computers. I have 1 that shows and 2 that dont show this checkbox.

I'm not quite sure about the Out1, Out2 and OutA, OutB setup.

Can you please advice. 

Best regard

You need to use 0V and OutB for PWM. I tested 2 PWMs just now and both outputs work like they should. 

You need to define 2 load cells to enable 2 brakes. You will not see the option Control brakes independently if you only have 1 load cell defined.

I will add some more details in the wiki.

Let me know if you have further problems!

Please report how those Loncont regulators work out. There was another guy who tested a version similar, but the regulator was too slow. There are different versions of them, so let us know! I see it can use a 0-5V analog control signal too.

Thank you. Read a post description jumpers, and with google i found this page.

I think that should be in the wiki as well, along with the outB being the primary output.

Break 1
LSA-H3P25YB Com -> YourDyno Out1 0V
LSA-H3P25YB 0-5v -> YourDyno Out1 OutB

Break 2
LSA-H3P25YB Com -> YourDyno Out2 0V
LSA-H3P25YB 0-5v -> YourDyno Out2 OutB

And both outputs are now working as expected.

I will report back about the Loncont when i know more.
