This should be the last thing I need to replace/fix for my machine. Got a cimbali Bistro 2 early 90s. It uses a special relay, 9 pin, type 65.23, I cant find it anywhere. What relay can I use as an alternative to the original? I've attached a picture. Any assistance would be appreciated.
I tried Espresso parts, no go. Tried checking south Cali, nada. Apparently this relay is impossible to find. I did however find a different relay. It was recommended by an electrician who works on the Trolley here in San Diego. He recommended this relay (see below). It has less pins but has the same numbers on the old relay. I received it today and will be plugging it in soon to see if it works.
Relays have to match exactly. Factors have to match, such as coil voltage; contact amperage and voltage; type of contact material (determined by the load such as resistive (heaters), inductive (motors) or capacitive (controls, etc); and heating factors (is the load momentarily or continuous)?
This is the relay I got. Amps is higher but that shouldnt matter. Everything elses matches albeit its set up a little differently. If I have, I will set it up today.
As I read it, when current closes A & B, terminals 1+4+7 close, terminals 2+5+8 close and terminals 3+6+9 close. Simple enough.
You're right about the current rating, more is better. Make certain the coil voltage is correct (AC or DC - this is important as each has different characteristics) and the loads they connect to..
If uncertain, I'd go with contacts rated for inductive loads as their designed to handle sparking better.
Here is the original one. If you look at the lay out vs the new one, its lay out is different, 32 is no longer in the middle top but on the top right. I am told to just follow the numbers on the old one and place them exactly where the numbers are on the new one. Enigma-2, you seem to understand this WAY WAY more than I do lol. I am relying on the expertise of other people who have 0 knowledge of espresso machine but know quite a bit about electrical stuff ;p
Also as I recommended before, try emailing coffeetec customer service, tell them your machine make and model and see if they have a schematic. If they do, (many high end service dealers have information on different machines) they may be able to find a replacement relay.
Are you asking for the schematics of the new one or old one?
For the new one, this is what I have. The person who recommended me the new relay said, for example, on the old one, 32 is on the middle top. On the new one, if you follow the layout (see pic), it will be on the top right. And so on and on. Are you suggestion this might not be right?
As far as the old relay, I cant find jack about it. Its a Finder 65.23
If you search for Cimbali Bistro 2, you get universal relays, model 62.83., which is identical relay to the one I bought. It's also numbered the same way. Check it out.
The schematic I was talking about is for the entire machine. Sometimes thd manufacturer includes an electric schematic to aid service shops in repair. It's problematic however. Why I'm recommending contacting a service dealer.
It's going to cost, but considering the value of the machine spending a hundred is not a big deal.
Based on the information you supplied, it's not possible to give a better recommendation.
What I would do (besides looking for a service dealer who has access to the service information) would be ohm out the relay and create a schematic. Be a starting point at least.
