ID tag, termination resistor help

Mr. Blonde 3 days ago updated by Rainer Vermaasen 2 days ago 8

I have an IQAN MD3, XS2 & XA2 set up in an excavator as part of a hydraulic attachment. The system is no longer supported by the OEM as they are no longer in business. I’m in need of some resistors and one of them is proving to be difficult to find.

The resistor is marked 1T and according to the Parker literature there are four versions of this resistor and it seems the connection ends are the difference between them. So my thought is I can use any Parker 1T resistor and just solder it in.


Am I correct in my thinking? Thanks in advance.


Chris

You are correct in that the difference in resistor part numbers is their connector pin terminations. You can therefore simply cut off the new ends and re terminate- soldering is not an option as the resistors are designed to be installed within the module connector plugs which Parker have changed as the hardware has evolved over time. There is nowhere practical to solder them. Your system uses old ( and now obsolete) modules with Saab connectors- the correct parts are still available from Parker Iqan distributors even though Parker has now discontinued them.

(Suggestion: Rotec Hydraulics Ltd stock them)

If this is a critical system for you then you should consider a hardware upgrade asap as replacement modules for your system  are now very difficult to source.

AndyR, thank you

Letme be clear the only experience I have dealing with IQAN is whatI’ve been forced to learn over the past couple of weeks while trying to work my way through some problems on a product that I can’t get any support for because the OEM is out of business.

One thing I have learned is, as you have pointed out, my system is old and obsolete. This being the case is a real problem for me and my company as the purchase of this attachment for our excavator was a HEAVY investment and within 5 years of purchase, support for both parts and technology were discontinued when the original OEM was bought up and re-structured.

it’s not just a lack of support from the OEM, it’s the difficulty with sourcing components such as there resistor tags. Even the hardware manufacturer has abandoned the end user.


Keeping that and my lack of experience with these systems in mind, without the OEM’s software can I upgrade the master and expansion modules? Could the software be removed free m my MD3 and installed into something newer? Would the software format be compatible with a newer unit?


I would like to like to explore this option to preserve the investment we’ve made but I honestly would have no idea how or where to begin.

Any insight that could be offer would be greatly appreciated.


The software can be removed from the MD3, but for that you need the IqanRUN software. When you have the software that it can be modified the fit on newer hardware with IqanDesign. Most likely the biggest problem is the password protection of the software. There is no way to go around that when the OEM used it.

as Ed has said your most likely main problem will be the almost certain OEM password protection. As a one off machine upgrade project, Parker won’t be interested to help you but there are plenty of Iqan specialist distributors and integrators out there- where are you/the machine geographically?  
Is the system a simple attachment to a standard excavator ( a tool for instance) or has the excavator been significantly  modified and this system now integral to its functionality?

Depending on the complexity, the software can be rewritten from scratch for the latest hardware platform but this inevitably won’t be cheap. Your existing application software( if it could be extracted from the MD3) would need modifying anyway as the screen layout formatting is different for the newest ( but much better quality, resolution etc) generation of screens ( all now touch type). The actual functionality of the application code is mostly transferable with some minimal tweaking into the latest master modules

The Iqan design and/or Iqan run softwares required are also subscription based and again are an expensive investment initially I’m afraid.

Hoping this isn’t too off putting for you. Nothing is impossible but this won’t be a simple home fix you can do for yourself I think.

The attachment is a highly specialized, telescoping demolition boom with a reach of about 140’ 

My thought is that the use of the IQAN system as used inmy application is pretty simple. The system does not tie into the base machine’s ECM or other control modules. The IQAN system is not monitoring any of the machine’s vitals or performance data. Simply put, the IQAN system is there to limit or enable hydraulic function using solenoids to control pilot pressure. This is all done through a series of 3rd party solenoid valves and pressure switches that have been integrated into the base machine’s hydraulic system. A lot of the machines function is based on the mode of use, “excavator” or “demo”. Demo mode uses an inclinometer to limit boom angle and some other functions.


The machine is located in the US, the northeast coast to be specific but could be sent anywhere within the US to work. 

Thank you again for the information, it’s very helpful and to be honest, knowing that a system upgrade may be possible is huge as we move forward. 

When you mention password protection, is this something that the OEM was required to use or would it have been their option to enable password protection? There is a chance I might be able to get that information.


if I wanted to begin exploring to process of upgrading my system, what type of services would I search?

Thanks again for taking the time to reply to post.

ok I see- nice rig

As you suggest, the Iqan control system sits essentially externally to the main machine ecu etc so the application code shouldn’t be too difficult to rewrite for someone competent in Iqan design The password protection in Iqan is an option rather than mandatory but any OEM worth their salt would have used it to protect their commercial and IP rights- I doubt very much there isn’t one on your application. if you can get it reliably then brilliant - you will save yourself a fortune in programming time for someone. If not you’ll need the OEM or ‘as fitted’ hydraulic and electrical schematics and someone with a very good understanding of how it works and what you want it to do- a good integrator can then rewrite it as required

As the machine is US based, my company , although within our remit, cannot help you  as we’re in the UK so not practical for us- hopefully another US based integrator on this forum will pick up this conversation and chip in to hopefully help you

Best of luck getting it sorted.

I am in no way affiliated, but GS Global Resources is a great with IQAN. I would assume they can assist. https://gsglobalresources.com/

If you need new IQAN XS2 modules, please let me know. I still have a few brand new modules in stock.
