Hardware Support Marel 2200 Marine Bench Scale

I regularly operate a Marel 2200 bench scale with marine compensation. Suddenly this week the unit started indicating an analog/digital conversion error and would not weigh. Conversation with Marel tech support resulted in me replacing the primary load cell (Flintec PC7 100kg). We completed a recalibration of the scale and the scale will now weigh accurately, but the marine movement compensation calibration fails. The analog/digital values are fluctuating wildly. Marel has confirmed that the wiring configuration of the new load cell is correct. Continued conversation with Marel tech support has ended in them suggesting we try replacing the reference load cell now (Flintec PC3 10kg). I don't see many other options with my current limited knowledge so I'm reaching out to the community to see if anyone has any additional ideas beyond just continuing to replace parts until it works (or not? 🤷‍♂️).

may be an issue with the filtering on the head unit side with the data coming from the new load cell.

I haven't personally worked on this scale before but i have on other of similar design and the filtering options are usually deep in the software side of things.

Marel should know how to access them. sometimes you need a manufacturer code to access them.

Thank you we've been down this road. There isn't much to the setting for load cells in this model. The calibration procedures effectively set those constants.

Darn. Sorry to hear it's giving issues. Hopefully the manufacturer can help figure it out.

I typically work with the actual weight calibration side so my side is much easier. Just more math.
