There are fast and slow speed sensors, but speed control is either fast or slow travel as per relays in the door controller. Door controller is the v200 I believe with plc, and hydro is older montgomery. I believe the doors were modded with the door controller, but it was done by another company.
Basically demand is for high speed and door travel is slower than it should be. The switches on hall doors are mechanical. I have not visually checked to see if the chains are slipping on the idlers. Not really very familiar with peelle doors, so learning as I go. Doors are verticle btw.
