Hello,

Our company is using the MD4 Parker Display for the logic of the exterior lights system on a electrical vehicle. We are currently in the process of certifying the system for the FMVSS 108. In said certification, there is a minimum amount of cycles that the lighting system has to respect. Usually however, the system contains a module that does the logic and in our case that logic is in IQAN. So is there an equivalent for the MD4 module, like the MTBF(minimal time before failure) for example, to prove that the exterior lighting system can support 175,000 cycles. 

Thanks for your help.

Hello.  I am testing my MC41 application using a Eurtherm G-438 ( https://www.farnell.com/datasheets/1658070.pdf?_ga=2.178838692.143399012.1654225772-1786236872.1616697046&_gac=1.2754052.1650585147.EAIaIQobChMIlfWcop-m9wIVTsLCBB0Krwa-EAYYBiABEgKL5PD_BwE)  signal conditioner to generate a 0-20 mA to simulate one of my inputs.  The MC41 is latching onto a high error and I am puzzled as to why.  I checked the output of the unit and it is in the proper range.  I made a work around using a trim-pot but I want to be sure that I won't have problems when the controller is connected to its real current source.  I noticed that the voltage compliance of the signal conditioner is 12 VDC max whereas my controller is receiving 28 VDC power currently.  Could this be the error?

Hi 

    The situation happened after flashing software for MD4-7.   I can't link to MD4-7 via CAN or Ethernet now that means i can't flash software again.  The system still appears images but it will enter blue screen state like photo if i sent some commands to MD4 by any CAN channels.  I try to shortly connect address PIN to enter safety mode but seems no influences.   Who has any suggestions for me to solve this issue ?  How to re-flash software MD-7 ?

Got this photo from a colleague who works in after-sales, an MC41 connector packed with di-electric grease.

The Molex MX123 is a sealed connector when properly assembled, so adding di-electric grease does nothing to improve protection against water and dust. Instead, it can only cause problems by getting in the way for the pins and prevent contact. 

I do not know how widespread this problem is. 

Do you guys also have problems with people putting grease inside the connectors? 

What is the max currant on the -V-ref on pin 23 and 35

Witam, mam problem z programowaniem wyświetlacza Iqan MDM, czy mogę zaprogramować lub odczytać program dla danego urządzenia za pomocą serwisowego, pobrałem program do tych wyświetlaczy MDM, czy muszę wykupić licencję na korzystanie z niego czy jest on darmowy

moze by mi ktos pomogc bo mam wyświetlacze i chciałbym je zaprogramowac bez rozcieńczania pamięci na inne urządzenia

Wyświetlacze nie są już dostępne i wystąpił problem ze starszymi urządzeniami

Dziękuję bardzo za pomoc

What does the serial number mean on an MD4 and MC41?

I think it starts with production year and weeknumber, but what do the following numbers mean?

Hi there,

I have a critical problem with MC41-FS stand alone controllers (ie it’s not connected on Multi-Master system). FW level 6.05.18.6047

We see operation continuous for about 2 months with no error, then multiple devices on the same mahcine just stop working ll within minutes of each other (with no CAN output) and no reported/broadcast faults or recorded System Log errors. This problem is seen on multiple machines now, and a pattern is emerging of this failure. Resetting 24V power, resets the module and the error.

Clearly having a module just stop operating with no reported or logged system errors is very dangerous, as we have no means to quickly diagnose.

We have managed to collect the LED blink code when in error state: This sequence is not listed in the manuals.

Blink code

4x RED

Stop

1x AMBER

Stop

21 AMBER

Stop

2x AMBER

Stop

1x AMBER

Stop

2x AMBER

Notes:

• There are 3x MC41-FS modules per machine (all independent)
• MC41FS power supply is continuous 24V
• The machine has a "main" Multi Master system which comprises of 2x MD4-7 and 3x MC43FS modules all on MM system.
• The 3 independent MC41FS modules are connected to each MC43FS module on J1939. As far as MM system is concerned, the MC41's are another J1939 module on the common J1939 line.
• The machine MM system is operated with switched power supply (24V)

Originally I thought this was possibly a CAN bus issue, but no other IQAN modules are reporting CAN bus errors (ie the MC43 modules) as they share the same J1939.

There is one possible interaction between MC43 and MC41 module that could be contributing (depending on what the fault LED codes are from above). The MC41FS module has enabled TDA for time sync, and the MC43 is configured to send TDA PGN onto the shared J1939 continuously every 10 seconds to time sync the MC41FS. As mentioned above, the MC43 modules are connected on switched power, and the MC41 on continuous. So very night the MC43 (and full MM system) is powered down overnight). I am unsure if this is a problem, or has no effect.

Please can someone contact me to discuss this directly. I am not able to share the project file publically.

I have couple of IQAN-MDL2 modules (good shape) if someone is looking for one.
