Argon Not working anymore

#1

Hello everyone,

I tried everything I found on the internet but eventually I ended up here.

I am using an OSW with a Mige 130st-m10010 + an Argon.

From one day to another suddenly my wheel would not phase anymore when switching it on.

I checked all cables and after that still not working.
Granity shows me the error message “under voltage !”

I bought a multimeter and used the argon supply voltage guide to measure everything.
I have the correct readings on the mentioned fuses on the board.

BUT the fuse with XICOM P 5W 47K J right next to the R7 fuse does not give me readings. I think R1 is written below it on the Argon board.

I did not find anything on the internet regarding this fuse and wanted to ask if thise fuse could be the cause of my problem.

Looking forward to any kind of help
Max

Hi

If the fuse doesn’t give any reading (short) then it’s blown and you will have no HV voltage.

Argon fuse instructions/specs are here:

Hi @Esa,

Thanks for your quick reply.

I was not reffering to the Glass Tube fuse but the fuse Marked blue

Or am I Missing your Point Here?

Hi Max

I indeed misunderstood a bit.

The blue marked is not a fuse, but power resistor.

The R1 is the bleed resistor, that discharged the HV capacitors when power is turned off. They are shown in the schematics here:
https://granitedevices.com/wiki/Argon_supply_voltage_troubleshooting

It specs are what you also wrote in your first message, i.e. 47 kOhm. It would affect only when being shorted, but then you would always blow the fuse, and there’s really so reason why it would get in that condition. It’s much more likely that the R7 has been broken. That is the charge current limiter that is bypassed when the Argon is first turned on.

To clarify your description, do you mean, that you have ok resistor measurement from R7? If so, please listen if you get one or two relay clicks when the Argon is turned on. If only one, then the RL2 to bypass R7 is stuck.

Let me know how it goes.

When I measure R7 I get a constant value of 33ohm (ohm I guess, I am really bad with electronics…). So to me this looks to be fine and alright.

When I switch on the Argon I can barely here one click. It is very silent. Not sure if this is the clicky you mean.

Also attached now my current Argon readings. Are my settings right? Just to rule out I have wrong .drc settings…

Any ideas @Esa?

Hi Max

Sounds like you have stuck relay (RL2). They are not loud when they click, but clearly audible. Two should be heard when turning on the Argon. First one is the STO-relay, second one is the R7 bypass relay.

This has been covered e.g. here:

Kind regards, Esa

#7

Thank you @Esa.

This might Sound stupid but how do I apply the 5Vdc to the Pins and where on the Argon are those Pins A1 and A2?

#8

Hi Max

The location of the RL2 pins can be found in the forum thread I linked. The RL2 pins look like the image from the bottom side of Argon PCB.

The idea is to have a 5 to 9 V power supply, e.g. a battery, and use separate wires to connect the voltage to the pins momentarily. Positive voltage to A1.

Kind regards, Esa

#9

Thank you @Esa for the explanation.

I Tried with a 5V battery and immidiatly Heard the clicks. But when I Put all the Plugs Back into the Argon and Power it on it still doesnt click.

I am Out of ideas now. Could the R7 be broken and still give me a measurment?

Or is my Argon beyond repair?

#10

Hi Max

You have STO disabled? I.e. e-stop is released.

#11

Yes it is released. Can I shorten the Sto somehiw?

#12

I rechecked the E-Stop, it was not engaged. I disasambled it, and held both contacts together. Restarted the Argon, still no clicks whatsoever.

Can I be sure that the R7 is fine? It give me a reading of around 33Ohm. That should be fine right?

I am running out of ideas. Below the devicestate of today again.

#13

Hi Max

Your fault flags show STO active and Enable is not true, which means that Argon doesn’t get either STO disable voltage nor enable signal. Both are required for Argon to initialize.

How is your Argon wired? Please check Argon user guide for instructions.
https://granitedevices.com/wiki/Argon_user_guide

Kind regards, Esa

#14

I havent Changed anything on the wires and they are all in to correct Position. Could the fuse of the Sto be broken?

#15

Hi Max

How is your 24V wired to Enable and STO? Your Argon don’t get those signals, so you want to check those first.

Kind regards, Esa

#16

Everything is wired as it has always been, I rechecked today, checked if all wires are in place, still no solution. I am out of ideas.

#17

Hi Max

Did you check with multimeter, that the 24V signal is properly switched to Argon?

As you have STO enabled and Physical Enable signal is not present, you need to check those signal paths first. Check that your e-stop is working and it connects the 24V voltage to STO and Enable inputs.

Kind regards, Esa

#18

Hey Esa. Where excactly on the Argon do I have to measure the 24V?

Kind regards
Max

#19

Hi Max

STO and Enable are wired to the RJ45 connectors, which are quite impossible to measure non-intrusively.

How are those signals wired to Argon? I would assume SMV2BRK, but this is an dangerous assumption.

If you do have that, measure the signals from it.

If you don’t have the SMV2BRK, please reply with images of your wiring.

Kind regards, Esa

#20

I have the smv2brk. OK Then i will try to measure. Otherwise should I Order a New smv2brk? Maybe Mine is broken?
