Anyone else getting this error “output fault” on they GX extender relay output,only happens now and again when engaging the relay.
What do you have connected to the relay?
Hi @Ewky,
Thanks for reporting, we’ll look into this.
I have some questions:
- Does this happen only when you switch the output on/off quickly?
- Does the “output fault” indicator go away without further action? Or does it stay on the UI?
- If it happens, is the relay still switched on and off?
Best regards,
Rein.
Hi,
Nothing at the moment!
1……. Correct, but I have it set up as momentary switching!
2…….no stays on,until a few more presses of the button.
3……yes,the relay still clicks on and off as per the button operation,with the fault displayed!.
Your welcome to log into it,as nothing is connected to that relay output yet!
Thanks @Ewky
I would like to login to the system. I’ve already found it, can you enable remote support for me?

Remote support is enabled, feel free to investigate
Hi @Ewky,
Thanks, I’ve had a quick look. There seems to be an issue with reading the actual state of the relay, which causes the actual state to be different from what the firmware expects, so it raises the output fault.
We’ll look into it.
Thanks for reporting.
Hi @Ewky ,
This issue is resolved per Venus OS v3.70~35.
It would be great if you can also test to see if it fixes the issue you’re experiencing.
Please let me know if it does not resolve it on your system.

Hi Rein,
It looks like the latest beta version has fixed this issue, thank you…..however one issue I find is, every time go into the remote console I keep getting the option to choose your remote console UI…. even though I’ve saved my preference and have ‘new UI’ selected under display & appearance! @mpvader
I had that problem, and it was solved by updating to beta 3.70-35.
Now I have another problem.
I’m using the I/O Extender’s PWM output 1 to control a 15A, 400W MOSFET module to dim a low-power 12V fixture.
When I test the control without power (12V supply at the MOSFET input), it works perfectly on the Ekrano. I can even use it through the red node, which is how I want to implement it for a fixture with timed dimming.
However, when I plug in the fixture and turn on the PWM, regardless of the intensity, the fixture turns on at the desired intensity, but the connection from the I/O Extender to the GX becomes intermittent and eventually disappears from the GX. When I disconnect the power to the fixture, the system reappears after a few seconds, or I have to unplug it and plug it back in.
I updated to the latest beta today, but the issue is not resolved.

Hi @Heraldo
Thanks for the report.
Controlling a load like this should not be a problem.
Can I login remotely on your GX to have a look at the logs? You’ll need to enable remote support.
Best regards,
Rein
Thank you Rein,
Of course you can. Remote support is enabled.
The system is currently connected and online. I only have the I/O extender connected to the Ekrano for testing.
In relay 2 of the IO extender, I connected a 230Vac 30W light fixture and as long as I don’t use any PWM output it works well to turn that light fixture on and off without dimming.
As soon as the MOSFET’s power input and output are connected, and then the MOSFET input signal is connected to the IO extender’s PWM output 1, the device continues to function correctly.
I can continue to use it to turn the light on and off manually or on a scheduled basis.
The problem occurs when I activate the IO Extender’s PWM output to dim a second 12V DC LED light connected to the MOSFET.
The problem starts just when I activate it, regardless of the dimming percentage.
I’ve done some programming on NodeRed for the test, which you can also see.

I forgot to mention that if you need or want to run an online test, just let me know, and we can coordinate a review together so I can connect and disconnect the system so you can see the error in real time.
For example: at this very moment I connected the mosfet and the IO extender appears disconnected, but physically the equipment is still connected.
sunny regards
Thanks @Heraldo
I’ve had a quick look and can see lots of USB / I2C errors related to the IO extender.
So if I understand correctly, the GX loses connection with the IO extender when the 12V power supply providing power to the MOSFETs is enabled? Or only after you have controlled the PWM output in some way? And does the issue also arise when you control a different PWM output than the one connected to the load?
The problem starts just when I activate it, regardless of the dimming percentage.
So the GX loses connection to the IO extender if the PWM output is turned on, even at a dimming of 0%?
In relay 2 of the IO extender, I connected a 230Vac 30W light fixture and as long as I don’t use any PWM output it works well to turn that light fixture on and off without dimming.
Do you also experience issues with the relay output? Or is that working properly?
485 / 5.000
Does the GX lose connection to the I/O Extender when the 12V power supply powering the MOSFETs is activated?
NO
Or only after controlling the PWM output?
As long as the MOSFET is connected and powered, and PWM control is disabled, nothing happens, and I can even use the I/O Extender relays. The I/O Extender only disconnects when I activate PWM control.
Does the problem also arise when controlling a PWM output other than the one connected to the load?
YES
So the GX loses connection to the IO extender if the PWM output is turned on, even at a dimming of 0%?
YES
Do you also experience issues with the relay output? Or is that working properly?
It currently works fine if I don’t activate PWM control, or sometimes fails when I’ve connected the MOSFET to power without activating PWM. It’s intermittent.
I used to have issues constantly, but after updating to version 3.70-40, I no longer have that issue continuously and it has become intermittent.
However, if I enable PWM control, the extender disconnects. The relays remain activated, and I can’t turn it off until I disconnect power to the MOSFET and reset the extender so I can see the controls on the screen again.
By the way, I’ve tried three different MOSFETs, and the result is the same. I even switched the power supply to a 5V DC power supply and a small toy motor to see if that was the problem, but it still doesn’t work.
Hello @rzee
I’m sending you an update.
I updated Ekrano to beta version 3.70-41 and the problem persists.
I look forward to your feedback and will be on the lookout for any updates. The system is already live in case you need to check it out.
If you need me to do any specific test just tell me
best regards.
Hi @Heraldo,
Thanks for the detailed video. I can reproduce this with an AC lamp switched by the io extender relay. I see the same behavior: sometimes when switching the relay, the GX loses communication with the IO extender. I also see this sometimes when applying the AC voltage to the relay terminals (without even switching the relay).
I suspect this is an EMI issue and forward this to the hardware development team.
Regarding the other issue with the PWM output switching a mosfet with a load, I’ll test that too when I have some more time.
Regards,
Rein.
Thank you, I look forward to your comments or if you need me to run further tests.
Regards
Heraldo
