Assembly Help

Hi

I am in the middle of my PCB build and I have a question regarding ZD1, ZD2, ZD3

1) Am I correct that they should not be installed at all. And if so should I put a jumper wire in place of the diodes?

2) Also there are no values for R24, R25, R26, R19. Are they also not installed and if so should I have a jumper in place of the resistors?

After this I will be ready to power test the board so I am quite excited to get the answer to this.

Thanks for your help

Hi Dan

please do not bridge ZD1, ZD2, ZD3 and simply leave them out.

R24, R25, R26 are unused and R19 is the resistor for the relais, on my board with a 24 Volts Relais it is bridged.

take a look at here, http://www.ardumower.de/media/kunena/attachments/905/TranslatedcopyofPrototypPlatine.docx.pdf , probably it will help you.

Thanks Volker,

One more question, is R19 just bridged or if not what is the value? I don't see that. I do have that document but some parts of the translation are not clear to me. Thanks.

Hi Dan,

if you have the board and parts from the shop (with the included relais) then the value is zero ohms.

I am building everything and getting my own parts. So if the value is 0 ohms I assume then that you mean just to jump the soldering pads with wire. Correct?

Yes :cheer:
