I have some Smartrise C4 controllers on Schindler equipment with overhead torin machines. Keep in mind that there are alot of parameters/monitoring that can be turned off with Smartrise. This became an issue when someone turned off the brake pick switch monitoring and had a machine pulling through normal brake. Only holding on emergency brake.
Also if you have emergency power/generators I haven't been able to get these functioning at contract speed (350fpm) I can only get them to run at 15-20fpm which will trip run timer on multiple floor runs.
That being said they have been fairly reliable for me, however Smartrise te h support isn't what it used to be when I installed the.10-15 years ago.
