Right I have a 150mm insulated Ruck Box, and have just bought a RE 3 Transformer which is a
Manual five-step transformer
(Here is the Manufacturers Description)
A single-phase transformer which controls the fan speed by altering the supply voltage in five fixed steps. The steps are adjusted manually, using the control knob on the front of the unit. The transformer has 230V terminals for operating dampers, electric heater batteries or other external equipment. When the transformer knob is in position 0, the outlet has no current. The indicator lamp on the front shows that the transformer is in operation. The fuse may be reset from outside. The RE has a selfextinguishing thermoplastic casing.
Technical parameters
Item
Parameter Value Unit
Voltage 230 V
Phase 1 ~
Frequency 50/60 Hz
Current 3 A
Enclosure class 54 IP
Weight 2,5 kg
Width 105 mm
Height 200 mm
Deep 105 mm
Wiring
Transmisson Supply Earth Fan
voltage
Transmisson:between ~ and N is always 230V when the transformer handle is in pos. 1-5
OK so on the wiring section there are 9 places where wires can be input, I cant upload the PDF, so I will list them, but also if you are willing to go to the systemair site here
and navigate to
Electrical Accessories Ventilation->
Speed Controls, Electronic ->
RE ->
and then hit the
RE 3 Transformer link on the right side and then hit the wiring link and it will show you what I am trying to explain, unfortunately the way the systemair website is layed out it wont let you copy a direct link to that page.
Basically there are 9 spots, from left to right, with a description of the symbols next to it:
relay connection(arrow down) - (Squigly sign, I assume its positive?)
relay connection(arrow down) - N (neutral)
mains(arrow up) - N (neutral)
mains(arrow up) - (Squigly sign, I assume its positive?)
earth -
earth -
earth -
fan(arrow down) - N (neutral)
fan(arrow down) - (Squigly sign with an arrow pointing up towards the right, I assume its positive?)
I hope that has been descriptive enough, but it might be easier to look at the diagram on the systemair website.
My main concern is about the relay connection??? And Also what the squigly line with the arrow through it means? I am thinking that I can hook up a power cable from the socket to the mains arrow up ones, and an earth, and then hook up the fan(arrow down ones) and an earth connecting up to the fan, job done, but I am just concerned about the relay connections including the extra earth for it. Is the relay connection just to hook it up to other units or something, can I just completely disregard it, and do what I have said above??? I just dont want to fry this fan speed controller or my fan really?!!!!!
Any help is greatly appreciated! I really need to get this wired up and need some help/advice!!!
