First post here, typical new forum member looking for help…
I’ve read through almost every post with anything mentioning this machine and I have not found anything just like the issue I am having. The machine was working fine and then it was moved, stored for about a year then moved to its current location. Following the normal start up, turn on machine breaker, reset estop, turn on controller and hit reset, this turns on the main power and fans are on. The controller power supply is on but there was no activity on the monitor. I checked the power outputs on the controller PS and they appear to be outputting voltage. I don’t have a spec on the power supply but there is a post on this forum that lists some values and talks about a Meanwell substitute as a possibility.
There are red LEDs on a couple of the cards indicating a WDT failure (what it says on the cover)and I don’t know what that means. So over a few days I checked connectors, tightened terminal screws, removed and reseated the PCBs in the controller, inspected a couple of the boards for burned components or bad solder joints, etc. Then I was reading something that said not having air pressure and lube oil would limit certain things from working so I found that the air wasn’t on. I got that going and was surprised to see the monitor come on. It said tests were passed and at the bottom it said to replace the battery before continuing. I shut the machine down and went to get the lithium 3.6V it uses. Installed the battery and tried to start it up and it was back to no monitor and the red lights on the controller.
I have been in contact with Dynapath (wow, still supports the delta 20) and they say the air should have no bearing on the start up and it looks like a power supply problem. I’m still hoping for more details from them on the specific things to check but I’m sure it’s not high priority to solve the problem of a non-paying inquirer. I do appreciate the help they have given so far.
I’m going to double check the outputs on the controller PS based on what I found in the other post. I did discover that while the required voltage for the main power is 230V 3Ph the power actually supplied is 208V 3Ph. I saw in the set up instructions that you can change a lead to accommodate from 220V to 240V, but not 208. I did change it to the 220 setting but it didn’t help. The voltage getting to the Delta control PS is 107V, the tag says it should be 115V but the outputs seem correct.
To recap, everything is on, including the controller system, but there is nothing on the monitor and reset won’t start it. The monitor did come on once but not since.
Any insights or ideas are appreciated. I do have the set up manual for the mill, the delta 20 and a programming manual. I also have a set of schematics but they don’t include a lot of detail for the Delta.
