Have an issue with an older MiProm/ has no port to plug into / tried doing an upgrade to read what the redundancy flt was but gets stuck in a loop/ confirmed that was the correct chip for software upgrade also matched with a new power supply to no avail/ My issue I’m having is it gets some kind of redundancy flt which is not known but can be reset when powering down/ what is known is this is a 3 stop and if you leave elevator anywhere other then the bottom floor it shuts down/ time frame on how long that takes is not known/ have tried drifting it out of floor and it relevels fine would anyone have thoughts on this

Not familiar with the 2100 designation. Is this a standard 3 stop hydraulic, with inputs that are red, and outputs that are green? if so has anyone looked at the status of them when it is shutdown?
