I'm having an issue on a MD4 where I have turned the terminate CAN off on all 4 busses but they still turn on the internal resistors. I end up with 40 ohms as I have 2 physical termination resistors already. If I power cycle the MD4 the resistance will be 40 ohms for a min or two and then it drops to 60 as it should be. then I power cycle the Md4 and resistance goes to 40 again and then drops after a min or two. Its seems like the MD4 will not take the changes but it has been set this way for several months and it has been reprogrammed dozens of times

Good morning or evening, i have a question regarding the LS and also the HS outputs.

I want to control the blinking of some LEDs using the HS or the LS outputs (MC4X/XC4X), seeing the internal schematics from the instruction book, it seems the outputs are MOSFET outputs, just to be on the safe side, i want to make sure if they can handle switching frequencies (ON/OFF) of 8Hz (every 125ms). According to the help manual from the IqanDesign these outputs are supposed to be used for lamps among other things.

If they can, just for curiosity, what is the maximum frequency of switching they would be able to support, do they depend on the cycle time?. 

Thanks in advance!.

Hi,

We have in a electric cabinet one MC43[0] with a MD5[2], then we have a wired console 30m away with other MD5[1] together with 2 LC5 joysticks.

The problem is on MD5[1], we make 3 diferrent connection to check:

1) We first connected the LC5[0]+LC5[1] on its CAN B port as usual in previus system with MD4 we made. But Randomly we gets:

So we double check all the harware and wiring with no problem found. At this point was coneected 0T and 1T on each LC5

2) Then we connect one LC5[0] on the CAN B port, and the other in the LC5[1] CAN C port. Then we gets:

So the problem now is just on LC5[1], but with Multiple Addres Error even being alone in the CAN C port. At this point we added a 120ohm resistor on the MD5[1] to match LC5 termination resistors.

3) Then our last seting was LC5[0] on the CAN B port, and change the address to the other LC5[0] on CAN C port, so we gets:

But in each port, there is only one LC5, so is not posible to have a Multiple Address Error. 

The only way to make this work again is reset the whole system. This problem is happen in 4 diferent machines, all with MD5. Other machines with MD4 don´t have any problem.

Hi everyone,

I am looking for the original manual/instruction book for the first-generation IQAN-MG module.

I have managed to find the documentation for the IQAN-XP expansion module (Publ. no. HY17-8329/UK) on Parker's servers, but the manual for the IQAN-MG (Document no. 158221) seems to be missing or no longer available for public download.

Does anyone have a PDF copy they could share? I am specifically looking for:

• The full connector pinout (42-pin connector).
• The LED status/error codes for troubleshooting.

I'm working on a legacy system and any help in locating this document would be greatly appreciated.

Thanks in advance!

We have an MC41 connected to a PLC via the CANbus.  We push 16 RPDO blocks from the PLC to the MC41. We are on our 10th unit and suddenly on unit #10 we are not getting any values from RPDO 11, and it is greyed out when we look at it with IQANdesign.  Help?

Hello,

I am currently working on a machine that uses an IQAN system with an MD4. For some context: it’s a mobile hydraulic machine driven by a diesel engine. I’m running into an issue that I haven’t been able to pinpoint to a specific cause, and I’m wondering if anyone recognizes this error code or has ideas on what I could try next.

The error code I get is:

Run fault PID 90131 TID 14 Signal 11 Code 0

The situation is as follows. When I start the machine, everything initializes fine. The whole IQAN system comes up normally, the UI works, and I can operate the control system without any issues. When I give the signal to start the engine, it works in two steps:

First, the engine ECU is powered up. Then the ECU sends an OK signal back, after which I need to trigger the start again to actually crank the engine.

The ECU and the IQAN system communicate over CAN. However, as soon as I give the first start signal and the ECU powers up, the MD4 immediately goes into a blue screen and completely locks up. Nothing responds anymore, and I can’t recover from the error without completely disconnecting the system and doing a full reset.

As far as I can see, there’s nothing useful written in the logs that I can trace back to the blue screen—only the information shown on the display itself.

I’ve been trying to diagnose this for a while now, but I’m not sure what could be causing the fault in the first place. The only thing I could find online was a post mentioning CAN bus overload, but I don’t really see how that would apply here.

At this point I’m mainly looking for ideas on what could cause this error, or where I should start with further diagnosis. Any ideas are welcome.

Hi,

I need some help.

I have trouble using CIN sensors.

I have no problem with any others sensor types, but with almost all current sensors (4-20mA), I get an error with the signal (24mA) after some use.

But not all the time.

For exemple, here I have some undesired spikes while measuring.

Spikes are very short so I can't read +24mA in IQAN but I think if there was longer, I would have 24mA, so more than my scaled value at 20mA

For this exemple, the value come back to a good value quickly, but sometime it stays in error ~= 24mA

Have you ever had similar problem ?

Do you have some advises ?

I can't use Vref+5V because my sensors can be supplyed between 8-32Vdc.

The sensors used are made with 3 wires : +24V / 0V / Signal

So the wire 0V is connected to the 0V of the battery, but on every machine, the 0V of the battery is conencted to the chassis of the machine.

Iin the manual it is recommanded to do not connect the 0V to the chassis. It's not possible on mobile machine.

So we tried to connect the 0V to the VREF- but it's doesn't work obviously.

Is there a way to have a VREF for sensors that supply about 10Vdc ?

Hope someone has some experiences that can help us to understand this problem with current sensors !

Got the R4:2 1:1:3 I/O startup test failed error on a MC42FS module.

Even when I only put power (24v external power supply) and a address tag on it.
Tried to put an empty program on the controller. The controller is installing the program but when it restarts it keeps coming back with the same error.

Is there anything I can try to fix this?

The MC2 unit is now obsolete, but we still have units in the field that we need to support, the MC2 unit went through 2 part numbers in its life time as I can see, 20070899 - replaced in 2015 by 20077787. 

What is the difference between these unit and if I found an old one for sale would I still be able to use utilize it? 

Can the MC2 unit (20077787) still be purchased by special order if needed? 

Would like to use the HS+LS configuration to control the HV contactors in an Hybrid configuration.  I am reading note about using Diode to protect against EMF.  But I cannot find specification on acceptable EMF level?  Our contactors have built-in EMF clamping diode rated at 150V?
Also how does the open circuit detection in an off state works?  injecting a current i am assuming. How much?  Just want to avoid issue with Dropoff voltage for the coil.
