Hello, I am working with an XC43 current output that controls a bidirectional valve and want to make sure I use the right resistor to avoid problems with getting short and open load errors. I have found the minimum resistance for my case is 20ohms based on Appendix A in Parker's Family instruction book, but I am not sure how to find the maximum. Any help would be appreciated.   

Hello, I have a current leakage problem in the XC-43 and XC-44 modules.

I am using Digital Out HS outputs to drive LED blinkers, but they don't turn off completely, there is a 5.8V voltage leakage. The flywheel diode is installed but we have had to install some power resistors in parallel to get them to switch off completely. The same problem has appeared when connecting a buzzer to Digital Out HS.

hello, 

i am this XA2 error in one of our 7ech forklifts, the machine is fully operational, but this error keeps on popping up ‘VREF error Value 4.98v’ can anyone explain why?

Hello,

I encountered a strange problem with XA2 module.

For some reason the VREF voltage fluctuate between 5 to 5,5Volts and due to that all the VIN-channels turns on simultaneously around 0 to 30% and the crane moves without touching levers. 

Replacing XA2 module didn't solve the problem.

Is it possible that there could be some grounding issues in VREF circuit or has the MD3 display unit any affect on XA2 VREF circuit?

Hello,

We have a customer with this error pattern in one of the XC42 installed in the machine: R4:3 3:1:6

But we can’t find this pattern in the manual.

Can you explain what this blink code means, please?

Best regards

Is there a reason why the XC2x family of modules is missing +BAT diagnostic channel? I'm wondering if its a hardware limitation as the XA2 (below) and other modules appear to support it:

My customer needs to know the value of supply voltage on XC21 to read out on the master display. Unfortunately it needs to be a live readout rather than a digital flag if the module was to drop comms due to a low supply voltage. I will place a simple voltage divider circuit in if there is no workaround possible within the software but thought I would check first.

I am looking for a module that can accept 8x 0-10V inputs, but all I am able to find is an XC41. Is there a better way to do this than teaming up 4x XC41's?

I have a system with a MD3 controlling a XA2 with several relays and solenoids controlled by DOUT channels when certain unrelated circuits are activated the DOUT power pulses continuously as long as the other circuit is activated.  before and after using this other circuit that does not run through the XA2 the unit operates as normal.

what would cause these outputs to pulse?  Their status even changes true/false in the MD3 monitor screen as they pulse. grounding has been confirmed and checked at different locations.

I was forced to change my Pressure Transmitter due to the world-wide supply chain mess.

One that I could get my hands on that looks like it should be able to do the task is the IFM PU1700. I get wild reading from it when read by the XA2, but when I read it with a multi-meter, the voltages are right were I would expect them to be.

Any ideas of what to do? Is there a way to determine what will work and what wont without buying, waiting, and trying? 

The Leakage Current/Voltage from the Digital Outs make it difficult to control LED's and Audible Devices without using a relay/resistor/other.  The Leakage Current/Voltage is also making it difficult if the Digital Outs are read by other electronic devices (off is not off).  How does Parker recommend interfacing with these devices using the new XC-43/series modules? Adding external devices to these circuits is making the XC-43 modules not very convenient.
