Subject: Vibe-to-Roatary Pump Converison Wiring Questions
 

I am currently in the process of performing a vibe-to-rotary pump conversion on my Faema C84 single group espresso machine (Auto dosing functions).
I have sourced all the parts/supplies and am ready to finish the final wiring but wanted to get some specific feedback before I make the final connections.

Current Vibe setup:
-72 watt FOT vibe pump hooked up via 3 leads (FOT pump contains live/neutral/ground) which are colored Red/Blue/Green-Yellow. The FOT vibe pump leads are connected directly to 3 leads feeding from the Faema dosing control box (live/neutral/ground), respectively Blue/Orange/Green-Yellow

The FOT pump is currently hooked up as follows:
FOT-pump Red wire hooked to Control board Blue wire: I believe this is the live/power
FOT-pump Brown wire hooked to Control board Orange wire: I believe this is the neutral
FOT-pump Green-Yellow wire hooked to control board Green-Yellow wire: I believe this is ground

The replacement SPM compact drive motor also contains 3 wire leads (same colors as FOT vibe pump) which are Blue/Brown/Green-Yellow. I am making the assumption that the SPM drive motor would be Blue=Live, Brown=Neutral, and Green-Yellow=Ground. The SPM drive motor is the same size/specs as the Duetto and Vivaldi rotary motor, roughly 1/5HP and 120watt.

I am not going to simply hook the control board's leads directly to the SPM drive motor leads as I am installing an 8-pin solid state time delay relay in between (time delay added for preinfusion). My plan is to actually feed the relay with live power directly from the actual power switch which powers on the machine. The reason is because I am not looking for the factory control board to actually feed the SPM Drive motor as I do not want to put the added strain on the control board's circuit; also the factory vibe pump was actually a 52 ulka and I would be hooking up a 120watt SPM drive motor

My question is pertaining to directions on how to properly wire the solid state relay between the control board wire leads and the new SPM drive motor.
I am using the following 8-pin solid state time delay relay and need to know which leads to go which pins:  DPDT MAGNECRAFT W211ACPSOX-7

I believe all 8-pin DPDT relays would be wired the same way.
The leads I would need to attach are as follows:

Control Board Leads:
Red-live
Orange-Neutral
Green/Yellow-Ground

SPM Pump leads:
Blue-live
Brown-Neutral
Green/Yellow-Ground

Main Power switch:
Red-Live
Black-Neutral

What are your suggestions on which leads specifically go to which pins on the relay?
Any help would be much appreciated.
