Controlling 9V/2.7A prop valve with MC4X

Deanne 1 year ago in Master modules / MC4x updated by Gustav Widén (System support) 1 year ago 3

Has anyone tried to control a D1FBE01HC0NMWO (9V/2.7A spool) with a PWMOUT, if so what is the performance like? The rating for COUT is 2.5A so I will have to utilize the PWMOUT HS. I have read that COUTs allow the best performance with solenoid.

IP Cameras HTTP Streaming Phone Screen

ksilovich 1 year ago in Master modules / MD4 updated by Lars Bolduc 1 year ago 3

I have a project where I am trying to stream a video of my cell phone to the MD4 display.   As I want to be able to view google maps on the display for an in cab display.   

I noticed in this post that it looks like the MD4s support HTTP streaming,  

https://forum.iqan.se/communities/5/topics/295-md4-updated-list-of-tested-functional-ip-cameras

And I found this app that will do HTTP streaming via MJPEG

https://github.com/dkrivoruchko/ScreenStream

And then I get an access point connected from my Phone, PC, and MD4 display. 

The phone has an ip address of 192.168.128.10:8080, and I can view the stream on the PC, but I cannot view it on the display.  

I tried to type in "HTTP//192.168.128.10:8080" in the URL and that didn't work, and then I tried just the port of ":8080" in the URL.    

Can you confirm that the MD4s support HTTP streaming and if so what port are you using, as I can change that in the app settings if its not 8080.  And how would I configure this in IQAN

PWM Output - Doesn't Work with Low Current Load

ksilovich 1 year ago in Master modules / MC4x updated 1 year ago 2

I am trying to us a PWM HS Output on an MC4x to drive a signal needed for a PWM fan.  I will get an open load when I try to drive it directly, and even with disabling the open load check it still will not work. The output just stays at 12v.   

If I add a 1k resistor from the PWM output to ground, everything works as it should.   But now the issue I have is with no power to the MC4x,  I have some leakage voltage in the range of 50ma which will draw the battery down. 

Is this a software or hardware issue that will not allow me to use this PWM output to drive this fan directly??

My work around is using a relay to make and brake the resistor to ground when the MC4x is powered.  But this is not a great solution, and would like to see if this is just a software issue that could be fixed.

MC2 controller red led flashes rapidly

Philippe Laguë 1 year ago in Master modules / MC2 updated by Gustav Widén (System support) 1 year ago 1

Hi 

We have a MC2 controller that works normally for some time then it stops.  It works again after power cycling it.  The led flashes in a pattern not in the instruction book.  It just flasher red very rapidly.  Any idea on what the cause can be?

TOC2 mechanical adjustment issue

Markus Seppänen 1 year ago in Master modules 0

Hi,

Recently I had to adjust ramp values on TOC2 system using by screwdriver.

The whole crane control system has two TOC2 modules and I succeeded to adjust the first one.

When I tried to adjust the second TOC2 module by pressing the push button, all A and B LED's start flashing but I couldn't choose the particular function by moving the control lever. It just stayed on that Auto select mode without responding to any movements. The crane moved anyway during the adjustments and at normal operation mode corresponding LED illuminated.

I connected the TOC2 to IQAN develop and ensured that "adjustable" button was enabled on output channel, and it was.


Also, something unexpectable happened after I got the program from the first TOC2 and didn't send it back nor changed anything on it. As a result, I lost the ability to adjust it by screwdriver anymore and the values were changed.


Eventually I managed to adjust correct values via IQAN develop but the mystery of manual adjusting is unsolved.


Has anyone faced this kind of problem before?

Clone display to iPad/mobile/3rd Party display

Johan M 1 year ago in Master modules / MD4 updated by Andy 1 year ago 6

Hi,

Are you aware of any solutions to use a mobile or any 3rd party display to present the information that's visible on the MD4. No input are supposed to take place, its more about presenting data visible to people around the machine. In this case a saw mill where the MD4 are located inside a control room limitied to the operator.

Ideal would be to have a wireless solution.

MC4x parallel HS output usage

Chris Litwin 2 years ago in Master modules / MC4x updated by Gustav Widén (System support) 2 years ago 5

When an MC4x DOUT HS is wired in parallel, are you able to drive a single output as long as the over current limit is not met? What I driving at is activating both outputs initially, and deactivating one later.

MC4x DOUT HS or PWM HS Over current threshold

What is the current level that triggers over current diagnostics when HS outputs are used in parallel?
