MD4 and hydrogen sulfide (H₂S) exposure
We have experienced issues with two MD4-10 units where the touchscreens have become unresponsive. These master modules were being used on two different underground mining machines, operating in the same area of the mine with high levels of H₂S. Could there be a correlation between H₂S exposure and the touchscreens becoming unresponsive?
Looking for MD4
Hi, I'm looking to purchase a second-hand MD4 (and XC42) to replace our current control system. Has anyone got these in stock that could be shipped fairly quickly?
Thanks in advance!
What material is used for the molded rear panel of the MD4-10?
What material is used for the molded rear panel of the MD4-10? I was asked by a customer and couldn't find anything about it in the catalog.
24V MD4 with 12V relay on LS DOUT
Can a 12V relay be driven by the LS DOUT of an MD4 supplied with 24V without protection or diagnostic issues?
Actuating 24Vdc coil with MD4
Trying to actuate a 24Vdc coil for a skinner valve with the MD4. I know the MD4 only has LS digital outputs so I am wondering if we would need to use incorporate a voltage divider? I plan on using a relay for that coil as well.
Green line appeared on MD4
We have installed a brand new display in a battery powered rig this week. Its serial number starting with 2305 and production date of 230202.
It has been OK for a week but after the battery in the rig went flat, this line appeared:


Only thing I can think of was the battery was depleted and resulted in the display flashing when the battery got to a level where it was unable to power the module. It performed OK after the battery was recharged but after a few hours the line appeared.
Anyone had this problem or similar before?
Wrong ID Tag on MD4 Start up
When powering on the MD4 the system message "IQAN-Master Wrong Id Tag!" appears on the screen. This does not happen every time the machine is powered on but is getting more frequent. Restarting or shutting off the power to the MD4 does not resolve the problem consistently. The screen remains black when this issue happens. Any help is greatly appreciated.

MD4-10 Blue Screen while Ethernet Disconnect
Hello,
We are using a MD4-10 (IQAN-6) as main controller for our vehicle. Recently, a bluescreen appeared while we were disconnected from the vehicle via the controller's ethernet port connexion; we were measuring. When it disconnected, I also felt a small static shot from my laptop (I don't know if this is related to the error but it is something I have noticed when it happened). The error code is os_error(0x1000002) with run fault pid 90131. I have looked on IQANForum and I have seen this error before but not from the same source.
We are fixing the wire ethernet connector on the vehicle but is this something that has a precedent ?
Have you seen this type of error before?

Thanks for the support.
Best,
