Help wiring cooker hood for cafe

HLR Electrical · Apr 27, 2019

Hello I’m confused about the amount of wires for a cooker hood that need fitting into a speed control switch and then into fused spur. I’ll attach some photos but can you guys please help me on how to wire this?

Thanks

It should say on the instructions

Is there any gas appliances?

Yes but obviously there is no instructions and that’s why I’m asking.

Throw a few make and model numbers out and let's see

eliminating the gn/y as E, the you kave 3 Ls and a N. these 3 Ls will be 3 speeds. trial and error or bang.do you feel lucky punk?

Any photos of the controller itself?

Well do you? go on make my day, this is a pair of Klein Linesman pliers, the most powerful pliers in the world.

The controller rotary switch is the same as this but goes from 0 - 3

The wires on your hand x 6
Where do they come from?
Is the fan 3 phase or single phase?

Don't know what happened obviously wrong thread sorry folks

HLR Electrical · Apr 27, 2019

The 6 wires are connected into the fan itself. The picture is the other end of it which is to go into the switch.
It is also single phase.

Here i have managed to find a picture of the whole fan package including the switch in a schneider box.

The motor can you get a close up of that?

This is all I have of the motor

Lucien Nunes · Apr 27, 2019

If the capacitor is integral to the motor, then the MI's for a similar model from the same series confirm that there are four lines for four speeds, plus N & E, but it doesn't say which colour is which speed. I would take a few resistance readings to confirm that the blue wire really is N, and test them, although you may well also be able to confirm which L is which speed as they will probably be in order of resistance to N.

If there is no capacitor on the motor itself, then it will need to be in the terminal box and the above does not apply as one lead will be for the capacitor winding.

Identifying the correct terminals on the switch is a matter of 2 mins with a continuity tester. If you find three separate N/O contacts, obviously connect one end of each of them to line and the other end to one of the speeds. Park the line for the unused speed.

The datasheet gives the physical pinout of the connector, if one is fitted, which would allow you to confirm the functions of the colours. If yours does not have the connector, I think the sequence is as follows (by looking at the matching cable assembly)
1 / white
2 / red
3 / grey
4 / black
N / blue

Charlie_ · Apr 27, 2019

Is the cooker hood for any gas equipment?

No it’s not

Thanks, so when it comes to wiring the switch that’s what’s confusing, where is my twin and earth going and all 6 wires? I can’t get a wiring diagram of the switch anywhere

Is the control box heavy?
Is there a transformer inside it?

DT1991 · Apr 27, 2019

Bottom connections of that wiring diagram show them buddy.

There’s nothing inside, just a cheap box for the cheap unbranded switch

By sound of it Charlie the speed is controlled within the fan itself as opposed to a separate speed controller.

Charlie_ · Apr 27, 2019

Can you take the cover off the fan and take a photo?

Lucien Nunes · Apr 27, 2019

I think we've sussed the fan - the control switch selects one of four lines for the speed required. What the OP is stuck on now is how to wire a 4-position camswitch for 1P4W.

With the switch being marked 0-3, one speed (e.g. minimum) will have to be unused. It is likely to be something like:

White (speed 1) park in a Wago.
Red (speed 2) to switch terminal 1
Grey (speed 3) to switch terminal 3
Black (speed 4) to switch terminal 5
Blue (N) to incoming supply N.
Switch terminal 2 to incoming supply L
If they are not internally linked, it will be necessary to link terminals 2, 4 & 6 to extend the line to the other two contact sets.

Please check all of this with your meter before connecting up!!
