If you have Issues with IMS you can get a cable to plug into CON6 with your laptop and use Hyper Terminal to load the profile. Thyssen can provide you with the profile via email and you just choose the proper hand. This will enable your limits and set everything up instead of going through parameters. You should now be able to run smartfast to learn the doors. Thyssen has step by step instructions on this process in the LDO3 linear door operator manual with the UIT tool. Good luck and work safe.
