I was looking at the ziller website and I noticed two PCB  available. One is 58 hz the other is 60 hz and less money. What is that all about? Which one should I buy if needed?

The ones with with first stepped motors for speed regulation ran at around 58 hz.  I have had to change a couple, one for difficulties with the furnace operating and another that board had expired.  I have been using the 60hz version.

We would want to confirm compatibility before you ordered.

Good idea.

Thanks for the reply. I was hoping to replace my board with the 60 hz board can you confirm compatibility by the model/ serial numbers? Is there a good reason for the 58 hz system?

I couldn't get it to come up in Generac GenService by model or serial numbers. We would have to call Generac parts to go any further. If someday you get serious about wanting one let us know.

I'm sure there's a story behind it, but I don't see a reason not to go to the 60hz board unless for some reason it isn't compatible.  I tried looking online at your serial and model and nothing came up for me either.

I agree. We make certain it is a match either through GenService or Generac Parts before we would sell and ship it.

Thanks guys I am planning to perform a dip switch change this coming weekend. I am going to take a good look at all connections as well.  If that does not change anything I will call to order new board.

Remember after you make a change on the dip switches you need to power down the board and then repower it to make them stick.

Thanks peddler I was going to disconnect the battery and pull the fuses before messing with it.

Blaze, thanks for keeping us in the loop, thats how we all learn.

Update for all you guys that helped me figure out this phantom hz problem.  I did as recommended by buckshot.  I cycled the dip switches tried to ground out any phantom or static electricity on the control board after it was disconnected and removed from the unit. Turned dip 1 to on and dip 2 to off. Reassembled then started the gen and it went straight to 58 hz.  Just as a test I disconnected n1 and  n2 and the battery. Turned dip 2 on reconnected everything and started the gen.  It went back to 50 hz. So I am thinking that I need a new control board if I want the low speed excersize mode.

If it went to 58 Hz when you reset the DIP switches I am confused as to why you need a new board?  Those unit ran at 58Hz and increased speed a little with load.  There is I think a replacement board which gives you 60 Hz but not sure it is worth changing for that issue alone.  I would not set any generator to exercise at low speed.

The after setting dip 2 back to the on position the gen runs at 50 hz in manual or auto mode. From what I understand when dip 2 is on the gen should run 2400 rpm as a quiet exercise function and only run at that speed during the exercise cycle. I now have dip2 turned off which make the gen run at 3600 at all times 58hz.

Does anyone know the function of dip1?

Blaze, most of us don't recommend low speed exercise due to production of heavy condensation in the oil.

Dip switch #1 is exercise speed, #2 should be OFF, diagnostic manual say #2 is unused but I think you just discovered what it is.
Quote
Blaze
Do you believe that dip 2 is a 50 hz setting? What happens when dip one is off?
Quote
Blaze
I have not set the excersize function yet so I do not know what the excersize speed is. I thought dip 2 controlled that. I will check excersize speed tomorrow.

If dip #1 is "OFF" it will exercise in low speed, I've never messed with #2 'cause they said it was "unused" but that might well be how they run it at 50hz. So I'm thinking the switch might have been partway in the "ON" position or just some glitch(static, lightning, etc.) in the board that caused it to run at 50hz. I had a lightning strike close to the house a couple of years ago, didn't hit the house or barn but made my hair tingle, it whacked out my HVAC zone panel in the house - screen was blank. I removed power from the panel for a few seconds and re-energized and haven't had any trouble with it.

Originally both dip switches were in the on position. Now only dip1 is on dip2 off.  Is that correct for high speed excersize?
Quote
78buckshot
Yes, I would keep it set up for high speed, I think your only problem was #2 in the wrong position.

Thanks again to all the help on this. I now have 58 hz and high speed (3600) rpm excersize.  Buckshot knows his s**t.

Once in awhile we get lucky and make it work, we're just like doctors - still at practice. Thanks for the vote of confidence Blaze.
