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?

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.  

When connecting loads to high side digital outputs in parallel, the manual says on page 96 "Increased drive capability
Power driver high-side is connected in parallel with adjacent output to drive double
load current." On page 116 it states the max load per output is 4 amps and max load per group is 6 amps. So when you connect in parallel is the max load 8 amps? Or 6 amps?

Apologize that I have to use the wired topic.  Otherwise the submit window will go to search result and not be able to submit my question.

Why there are OUT_xxa and OUT_xxb?  Are there any relationship between them?  Have to use them in pairs?

I have issue regarding CAN bus critical error on the MD4,

can any one suggest me to reification above issue.

I am waiting for your valuable reply. 

Good Afternoon, All,

I am working on an old Iqan transmission controller for a company that has since gone defunct.

Do any of the old timers around here know anything about an IQAN MC1606?

Does anyone know how I would go about cloning the project so that I can install it on another used module?

Any information on this obsolete controller would be appreciated.

Can I get CAD drawings of the IOT MKII

Good afternoon.

Some years ago there was available the electrical schematics such as for example IQAN-MD3_uk_electrical_schematic.

Are these still available as I am after a copy of both pdf and dwg for:

IQAN MD4 electrical schematic

IQAN MD4 electrical system schematic

IQAN XA2 electrical schematic

IQAN LC5 electrical schematic

I am having a problem with the open load detection on a COUT on am MC43FS

1. I am running IQANdesign 5.03.14.5040
2. The manual indicates that the output detects open load two different ways which may be true, but the controller responds in three different ways.
   1. When the output is off, if the load is disconnected, the controller will set the open load status to TRUE, when the load is reconnected, the controller will set the open load status to FALSE and allow normal operation.
   2. When the output is on and passing some normal current, if the load is disconnected the controller will set the open load status to TRUE and turn off the output, if the load is reconnected, the open load status remains FALSE, and the output remains off until the command is set to zero. Setting the command to zero causes the controller to reset the open load status to FALSE, after which the output will respond to a normal current command.
   3. When the output is on, AND some fault causes the resistance of the load to increase such that less than 50% of the commanded current can be pushed through the load, the controller will, set the open load status to TRUE and turn off the output. Unfortunately commanding the output to zero does not cause the controller to reset the open load status to FALSE. This acts like the open load status is latched to TRUE if it was tripped by “extreme saturation”
3. It is my belief the third response is a bug in MC43FS because, a MC2 running IQANdesign 4.07.7.4605 works as expected I.E. commanding the current to zero would reset the open load status to FALSE Such that the controller could lower the current and try again.

Hi, 

I have a applciation with alots of safety control Dout. 

Like i could read a the page 97 and 99 of the instruction book manuel of the MC43FS. 

We can have 5 Dout.

In safety function we need to combine one HS and one LS pin to a output. 

In Dout i have acces to 5 direcly and would need 6. 

I would like to know if it is possible to use the pin C2:71 HS and combine with a other LS for example C2:16 ? 

Else my other solution would be to use Cout as a ON/OFF signal output unidirectional. 

Thanks
