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.  

Hi There, 

Hope all is well,

Is there any possibility to drive Proportional 24v 33Hz Pulsar valves with the PWM outputs from a MC43 ? Reading the manual it states that this will not work from MC43,but reaching out to see if it is possible.

ATM I am using the proportional flow from the pump and making the Pulsar more like an ON/OFF, This is working currently but would like to use the Pulsar proportionally. 

Thank you 

What's the realistic max bus length of master and diagnostics? I have an application that requires 2 masters at approx 100m apart from one another. Can these have master and diagnostic bus at this length?

I recall seeing in the IQAN instruction manual 40m is the recommended but maximum is 100m. Is this length take into account the 40 twists per meter, as 40 twists per meter at 100m length between modules would mean cabling of in excess of 100m actual cable length? If IQAN bus works at 250kbs, does this follow standard bus protocols and have a theoretical max of 250m @ 250kbs?

Will the soon to be added HS busses help any limitation?

I can always add an additional node to act as a midpoint transferring the data from one bus to another, effectively reducing the max length of a master bus to 50m, however it would need a diagnostics bus shared between all the master modules, which would be the maximum distance of 100m, and therefore the limitation?

Would CAN routing help me here with a central node that just runs its own independent program and routes the diagnostic bus and master bus through, and therefore has its own application file separate from the main 2 node application file?

What is the suggested solution for driving NG6 valves with standard 30W solenoids at 12V system voltage with MC4x/XC4x modules? 

We use the HS+LS digital outputs for driving Parker D1VW valves with "K" code solenoids in a 12V system. As stated in the instrucion book, max load per output is 2.5A, but the measured current is 2.7A (as in the D1VW catalogue). The measured solenoid resistance is 5 Ohm, but it should be within 7-14 Ohm (MC4x/XC4x instrucion book). 

30W solenoids are standard at other valve suppliers too, so changing the valve isn't an option. Change the system voltage to 24V also isn't possible for this project.

Hello,

got a constant red LED on the status light from a MC2 and "no contact" and IQAN MD3 screen

that constant light is not explain in the book, i would guess an internal crash, could you confirm?

Is MC2 module replacable by MC2-M14 ? any software update needed ?

Thanks in advance

Hi,

I have an MC41 module and I want to pick up the signal from a speed sensor M18-4VPFF200-Q8.

Thus I calculated my Max Frequency (Hz) = (Max RPM×Pulses per Revolution)/60 = (200*1)/60 = 3.33 ~ 3 Hz

Do you have any input on whether the issue might be software or hardware related?

Thanks!

We have a requirement to have multiple XC43 modules remotely to the master MC43FS module. Its likely they will all be powered from separate power supplies and they wont supply the same 0V for batt -ve.

Is this likely to be a problem in terms of interference etc?
