Re: CF-531 won¡¯t start after replacing selector switch

Todd,

I feel a lot better knowing that the switch came from Felder. It may be a pain but i am sure you will get it right. I have a feeling that Joe is right. If they sent it with jumpers, those were likely needed. Hopefully, Felder will be timely in their response.

Thanks, Joe and Imran

I bought the new switch from Felder. It was specified after their technician did his on-site troubleshooting to determine that it was, in fact, the switch causing the original problem with my machine.? ?So, I can only assume they knew what old switch it was replacing.? At the time, I had asked for a wiring schematic, but they didn¡¯t send anything.

?

As mentioned, the new switch came with jumpers installed between terminals, but I removed all of these and replaced them with jumpers to match the connections on the old switch.? I suspect, as Joe mentioned, that some of the jumpers that came with the new switch were there to replicate the switching function of the old switch.? I wish I had taken a photo of the jumper configuration on the new switch before taking them all off.?

I also saw reference to the A11 switch in the Kraus & Naimer catalog that Imran found, but couldn¡¯t find the specific model matching the new switch, nor could I find any reference to the old A14 switch.?

I hope to talk with Felder on Monday and get a wiring schematic for the new switch (and old switch, if different).? I will also reach out to Kraus & Naimer to see if they can help me with the switching configuration of the two switches.?

Of course, it¡¯s possible that I somehow didn¡¯t wire the new switch up exactly the same as the old one, but I was pretty careful ¨C doing one terminal at a time.?

Thanks again for your help and suggestions.? Will keep you posted.?

Todd
