I'm completely stuck on this step of my system build, cannot find the right wiring setup! Before asking I've searched all around, but didn't find a direction...

My system is going to be powered by the brewtroller microcontroller, in this way:

brewtroller -> 16 channels spdt relay -> electrical valves/pumps

This relay board has for every channel NO-COM-NC plugs (Normally Open, Common, Normally Closed)

A switch connected to the relay board makes the specific channel to react, I hear the "click" and the led on the relay board switches on. Nothing changes with the valve instead. Whatever I've tried with the valve wirings doesn't make a status change, the valve always sleeps :(

The switch is of the ON1-OFF-ON2 type, having to deal with a AUTO-OFF-MANUAL status for the channel control, being AUTO driven by the brewtroller.

I have two types of electric valves, 2 ways and 3 ways. Both of them are of the CR03 type, since the 3 ways has just two status (input1-outA and input1-outB) and the 2 ways have OPEN or CLOSE status. (valves code: CWX60P and CWX-15Q)

This is my valves schema

The wires coming from the valves are three: yellow, red, black.

I've seen some systems around with huge terminal blocks dealing the wirings and the powerage (in my case, brewtroller, relay and valves are all 12V) but I cannot understand how to proceed in order to control my valves...

Can someone guide me towards the right setup?

thanks and cheers! :mug:

PS now you can understand the meaning of my nickname... :D
 
If I read the wiring diagram correctly, you need 12v DC on both red and yellow to close the valve. Green is your ground/earth/common.

Can you actuate the valve on the bench by applying voltage red to red green to black and touch yellow to red to close and lift yellow to open?
 
Thanks! A little first success.

This is what I did:

V+ to valve RED
V- to valve BLACK
GROUND to valve YELLOW

The valve keeped alive, moving the internal direction flow from status 1 to status 2 (this test was with the 3 ways valve).

then nothing again... I've tried to detouch first the V+ (nothing) then the V- (after having reconnected the V+ to the RED Valve wire), nothing changes. I'd like to find the way to change the valve status back before proceed with the relay wiring
 
This is a dual action valve so de-'energizing it will not cause it to change state or return to safe.
It needs to be energized in one cofiguration to actuate to status 1 and in another configuration to actuate to status 2.
Is the wiring diag. You posted for the 3'way valve? I am assuming this valve has only 2'states ( position one and position 2)
 
Could it be that the switch is drawn incorrectly and it's:

green to 12v- negative/common/gound

12v+ to red for state 1 - (yellow de-energized or open)

12v+ to yellow for close -(red de-energized or open)

Just giving some options.
 
From the diagram it looks like you need to power the valve like this:

Red wire = Connect to relay (COM) contacts and V+
Yellow wire = connect to relay (NO) contacts
Green wire = V-

For open: / Relay de-energized
RED wire = V + (always powered)
Yellow wire = (no connection to V+ through open relay contacts)
Green wire = V-

For Close: / Relay energized
Red wire = V+ (always powered)
Yellow wire = V+ (now connected to V+ through closed relay contacts)
Green wire = V-
I hope this helps
 
Both you guys have saved my day! (and the following days as well!)

relay COM and V+ to RED wire Valve
relay NO to YELLOW wire Valve
V- to BLACK wire Valve

Acting from OFF to ON1 on the switch connected to the relay board makes the channel relay working and opening the valve (in this case the 2 ways valve). Moving back the switch from ON1 to OFF closes back the Valve

GREAT!!! I cannot say how happy I am now!!! :D

Great forum, great people!!!
