Thanks thats what i thought. Its basically (high low fan switch)NOT there in the wiring diagram. But according to this control panel for this model, it SHOULD be there.
Look under 'Control panel Ecco-SII' pg 10

I see what your saying, I even looked at the 240 volt venison to see if they had a two speed motor in that. Nope.

My best guess is the wrong control panel is being shown but it seems the only way to get the right answer is to call the maker.

Yes i agree, it just bugs me when you have equipment and you use the diagrams they send with it, and it doesnt show the proper wiring. ARRGH :(

The actual model we got has a 'single phase' motor, (460/480 volt) and the black is the 'common' . 460 volts for the low speed and 480 for high i suppose.the red and blue are the high and low speeds, so it doesnt show the relay contacts to control this. I can figure this out, but it just bugs me as i said before when i run into this (improper wiring diagram).

I have seen grilled venison, and also stew, and I have heard of high voltage venison, but 240 volt venison is something new entirely.

Come on up to NH in the fall and you and I can go 240 volt hunting. :grin:
 
as long as it doesn't involve cutting a hole in the ice and drinking all day in a shack the size of an outhouse, I'm in !
 
The SII comes with 4 different motor possibilities:

Motor 1/3 HP 480 Volt (Before F-79818 no pulse fan, Before H-90435 with pulse fan) 30200-03
Motor 1/3 HP 115/208/240 Volt (Before F-79818 no pulse fan, Before H-90435 with pulse fan) 30200-12
Motor 1/3 HP 480 Volt 2 Speed (After F-79819 no pulse fan, After H-90436 with pulse fan) 30200-16
Motor 1/3 HP 208/240 Volt 2 Speed (After F-79819 no pulse fan, After H-90436 with pulse fan) 30200-17

As you can see, *some* came with 2 speed motors while others did not.

I can't tell you how many times I have seen wiring diagrams not match the equipment they were supposed to be for. After some reverse engineering I will usually draw up an 'as built' and put it in the book for later reference. I will also note on the original that there is an error.

I probably see more of this than a typical sparky because I am likely to be called in for problems that have evaded people who have been trained to trust wiring diagrams.
 
brother, go to the 480v diagram it shows a two speed sw.

black is common to both speeds
blue from T3 on one contactor is one speed
red from T3 on the other contactor is the other speed

page 55

It sure does but the ECCO-AP 480 is not the model, he sais he has a ECCO-SII 480.

Of course the diagrams may be mislabeled.

If everything else matches then I go for the mislabeled wiring diagram

GO FIGURE! This never happens does it??;)

The only issue i have with this is that we were trouble shooting this equipment and this is what is found in the back of the manual (the WRONG diagram) for this model. I had to double check myself to be sure i know how to read a diagram. I guess i shouldnt always ASSUME the manufacturer would have the right drawings with the right equipment. So i ended up looking on line for this info.

Just hate having to do that when i have to trouble shoot. They (the manufacturer) suppose to let you know HOW the thing suppose to work, not the other way around!
 
Another issue with working in industry is that you never know what retrofits and changes were made to the equipment. Someone could have made some changes to it too.

This is true, but i guess i come from a different train of thought. This diagram is what was acutally 'sent from the manufacturer' with the manual. Also whenever there are FIELD modifications, we always udated the drawings/schematics we have for the equipment so people know what we did. Makes it easier for the next guy.

Just goes to show the proper 'labeling' and record keeping, cans save alot of time. ever wonder how many man-hours are WASTED over just silly stuff??, just my humble opinion.
