Wiring a Motor actuator for a four way valve.

[huffdawg]

• I have the motor actuator printed below , I know there are at least a couple members using this actuator and valve but I can't remember who they were.
  
  • I am looking for a connection diagram or a pic of how to wire the actuator with a 24v transformer inline to a control relay.
    
    Any help with this would be awesome.

• Esbe ARA663 - Paxton VM663
• 3-Point Floating Signal Motor Actuator
• 24VAC

Cheers

What are you using to control it? Constant circulation loop or does it operate only on a call for heat?

A Vesta controller. The 4 way valve is for moving hot water to storage from hydraulic separator or hot water from storage to hydraulic separator. I operate by hand at the moment. I will be setting up rules to move the water at certain programmed temps. I'm hoping to control the circ.in tandem as well.

I know somebody has an ESBE 4way valve and actuator like mine. I have talked with someone about it on one of my previous posts.. I've gone back over a few of them but no luck. Is there a way to search just your own posts.

Huff, I use an esbe motor actuator on my system to control a 4-way valve using one side of a double pole double throw 12 volt dc relay contolled by the NFCS. To do this:

1. Connect one side of your 24 vac transformer to the motor actuator (blue wire?). The motor has two windings, one for open and one for close. This is the common point where both windings are tied together.

2. The other two connections to the motor (black?, brown?) are fed back to the 12 vdc relay. One to one pole on the switch and the other to the other pole on the switch.

3. Connect the other side of the 24 vac to the toggle on the switch.

4. Connect positive 12 volt to one side of the winding on your relay. Feed the other side of the winding back to a Digital Out output on your Vesta. That should do the trick.

When the Digital Out is true the relay will energize causing current to flow through one of the windings of the motor causing it to rotate in one direction. When Digital Out becomes false the relay will de-energize causing current to flow through the other motor winding making it rotate in the opposite direction. Note: the motor will rotate a fixed number of degrees and stop.

Awesome, thanks a lot Don. I head off to work Weds morning so I won't make the connections but I'll get what I can roughed in. Do you control the pump on the same plumbing circuit as the 4 way valve with the same 12v relay on the NoFo controller?

That might have been me huff. I bought a 4 way from Don I believe. My actuator is the older 60 series that I found on EBay from Europe. It is 240V 50hz but will still work on 60hz. I'm still haven't taken the time to set my storage up due go lack of spare time. Don's description is pretty much how I see it wired too. My actuator will be activated by some more basic aquastat/relay logic though.

You would need to control the pump and motor actuator from separate relays and separate digital outputs. I have separate relay boxes for 120volts and 24 vac. Like to keep high voltage and low voltage circuits separate if possible.

Is this the switch you your referring to Don.. If so I will have to order it?

Thanks RK I did finally find the posts where you mentioned your ESBE valve .
Are you using the 4way from a hydraulic separator to storage and reverse or for some other application?

 

[Donl]

No, sorry for any confusion. The switch I am referring to is the poles and toggle within the 12 vdc relay. Same type relay used to switch your circulators on/off.

 

[huffdawg]

Sorry to keep pestering you Don.

one side of a double pole double throw 12 volt dc relay contolled by the NFCS

Is this relay separate from the one in the RM1206 .

I'm not understanding where the power source is coming from . I'm guessing you are bringing a 120v in from somewhere to be stepped down by the 24v transformer

Is there any chance you could sketch a wiring diagram if you have the time to spare.

Thanx

Huff, no problem, glad to help if can. I got lots of help several years ago from this forum when I started. I will draw up a diagram in the next couple of days and post it here.

Looks good to me!

Sweet .. things work a lot better for me when I put it on paper. I was also using NoFo's relay " how to" on the Vesta site.

And like you stated above , the motor will stop after turning a fixed number of degree's. Which in my case will be 90*
I was thinking that the motor would still keep trying to turn the valve because the circuit is always completed as a pole is always being contacted.

Looking forward to seeing your Vesta system fully operational.

No there are 2 micro switches inside the actuator and a cam activates one of them opening the circuit when the limit is reached. When power is applied to the other wire it tuns the opposite way until the cam activates the other micro switch.

I have a primary loop no hydraulic separator. The UG loop to the home is 700ft (350x2) as a tap off the PL with its own circ. I plan to combine them into one and the 4 way will connect this new primary loop to storage
