Anilam crusader m control problem.
Hi everyone I am trying to figure out why I'm not getting power out of my PCB 801 board, when I set it up on the bench with the 24v power supply hooked up to it and 110v powered into. When I do this I get the 110v power coming out of the board. Now when I put it back into the panel and wire it up the power out is zero and those power out wires go directly to the transformer, could I have a bad transformer and that's why the power out is zero. Any suggestions would be greatly appreciated.
Thanks Mike
Re: Anilam crusader m control problem.
What you might be reading on the bench is the leakage from the SSR. It is unlikely that the transformer is bad. Check all of the fuses, that was normally what happened to mine. Is the E-stop and reset relays pulling in with those buttons?
Re: Anilam crusader m control problem.
Well that changes things a bit :eek:
Even at that, the transformer is about the last thing I would expect to fail. First should be a fuse, then the veristor, then the SSR. You can check the transformer with an ohmmeter, should read near 0.
Re: Anilam crusader m control problem.
That is a pretty simple board, so I'm going to say a component(s) on the board has failed and should be pretty easy to troubleshoot. Unfortunately I don't have one else I would guide you through the trouble shooting. I eliminated mine when I upgraded the system. I don't remember exactly what signals are required to get the SSR to turn on, I know the E-stop, and I think the reset button was connected in there some way, but I think it also requires a ''system ready'' signal from the computer.
As I recall, that SSR is a 120V 25 Amp Opto22 unit with zero crossing turn on, with a 3 to 32V DC input side. I would confirm if the SSR is OK. On the bench, connect the output to a 60W or so light bulb, don't just go by a voltmeter, and try to turn it on with a DC signal on the input. You may find that you have bad SSRs.

Thanks Mike
Again, that changes everything. Post a parts list of what hardware you are going to use, and I'll get you started
I'm in the shop right now, but I'll pull up the schematics for my machine when I get back to my desk
Re: Anilam crusader m control problem.
Sounds like a good combination of parts, very similar to my system. Are you going to use the original servo motors? If so, the original servo drives are quite robust and are easy to use with any analog output controller like the Mesa 7i77, I'm still using mine and they work very well with the original motors and my new controller.
I would use a simple 3 wire control to energize the servo power. But you want to connect the E-stop and power on (through relays) back to the controller for monitoring so the controller knows the condition of the servo power and E-stop. You also might want to add a run permissive (controller ready) signal through a relay that is in series with the E-stop. That way the controller can power down the servos in case of a problem.
I would also use the SSR to power up the servo power supply, the zero crossing turn on minimizes the inrush to the circuit.
Here is a quick overview of my system, might be useful to get some ideas. https://www.cnczone.com/forums/knee-...24874-cnc.html

I think so, I never really did figure out exactly how that board worked. But I just used 3 small relays in its place.
If you take a look here https://www.cnczone.com/forums/knee-...24874-cnc.html you can see where I have the SSR hanging on the panel and it was then wired into the relays that that power up the system (not installed yet in the pictures)

Re: Anilam crusader m control problem.
Here is a drawing of the basic control circuit. The SSR is not shown, nor is the permissive input from the controller, but I think you'll get the idea. Just turn on the SSR with C2

No, it just looks that way in the picture. 1 and 2 (output) break the ''hot'' side of the 120V line to the transformer. 3 and 4 is the input to the SSR

That is correct. The reason you need a relay in the circuit is to provide the ''seal in'' contacts so you can use the momentary ''Reset'' button that exists in your panel.

They weren't installed yet in that picture. The original 801 board is gone, I used some small DIN rail mount relays I had kicking around. Similar to this one https://www.digikey.com/product-deta...082-ND/4755334
