Help wiring cooker hood for cafe

The motor can you get a close up of that?

This is all I have of the motor

 

[Lucien Nunes]

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

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]

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.

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

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!!
