As a slightly OT aside with delay timers.
I use a delay on timer on the CH circulating pump. This has a 20 min delay and is activated by engine start. Hopefully this gives the engine 20 mins to warm up before heating the CH system using the engine calorifier connections.
I also use a delay off timer on the same pump. This keeps the CH pump circulating for 10 mins after the burner stops firing, taking the heat from the boiler case round the CH system.
Finally, the main generator ship supply contactor has a 1 min delay on timer so that the engine settles before whacking a several kw load on the generator.

Hello again Kevin

Please ignore my previous link to timer. That one is an on/off timer - not delay off.

This one is a delay OFF timer but unfortunately comes direct from China.

I now need to get that rely in the power line somewhere to run on for a few minutes after the lights are out on the sunbed.

Jan, you are quite right to question it, glad to see you are on the ball! I did mention to Kevin that the colour scheme was strange but it is correct to the manufacturer's diagram and Kevin has confirmed that it does work wired to my diagram. Keep up the snow blowing!

I see the capacitor has 2 top connections. Neutral from the 'mains' and black going to the fan on top, where there are two connections
and the brown goes to the bottom connection

Please check...and when I am wrong..just tell me and as punishment I will not wear my thick hat when running the snow blower

Kevin it is a timing relay

this time relay can switch 8A @240 V. on pin 15 -18. ( when the relay is energized ) or pin 15 - 16 when ( the relay is not energized)
this replaces a on/off switch in the line to the fan. ( so you use 15 and 18 in the 'hot' wire to the fan

YOU still need a switch to turn the relay on/off
you energize ( turn on the relay by using 220V or 24 V )
if you want to use 24V to switch A4 = plus and A1 = negative. ( this can be 24V DC or AC. ..24V AC is used in Airconditioners and heating units)
if you want to use 240V to switch you use A1 and A2


CHRIS please check me also here. :)

This is a part of the system also but not essential. It lets the fan run on at the end for a set time.

I wonder Chris if you can tell me how to wire this so the fan runs on. I know A1 & A2 are the supply.

I see there is mention of lower voltage on the side. Can this handle 240v switching. Its for the fan motor.

Thanks.

Kevin

It is a bit strange in that blue goes to Live but that's not unusual with four wire devices.

Kevin, something like the attached. I don't know what capacitor you have but usually has spade terminals or flying leads. It states 3.5microfarads Make sure to put a 1A fuse in the live wire before the switch. Good luck!

That part number, 4VRE45-12T, appears on this manufacturer web site.

www.axair-fans.co.uk/assets/product-resources/download/Axair%20Fans%20-%20OEM%202013%20Edition%20(Web).pdf

Suspect it is a dual input 230 / 380 motor. Consult the manufacturer for confirmation of suitability and wiring instructions.

Hi.



I have acquired this fan.  240v. It has 4 wires earth, blue, black, brown.  It also I think needs this capacitor wired in because it doesn't run at full speed if just the blue and brown wires are connected. It also doesn't like starting. It will also run with blue and black and also with brown and black connected together. 



Can I get some advice on this please.



Kevin
