We're trying to get this lift back in service... The lift is a 3 stop, hydraulic elevator by Sedgwick. The home was foreclosed and the previous home owner had removed the DN relay. We've replaced the DN relay as well as the magnetic reader switches.
Problem: When a call is made (doesn't matter which floor) The elevator will only go up and stops on the final limit. The PLC registers the limit switches on the inputs, but doesn't seem to output anything.
We're leaning more towards replacing the Controller and related components, but wanted to try one last attempt to find a simpler, less expensive solution. We've contacted Quality Elevator, but they only sell some Sedgwick parts and do not provide technical support.
Anyone have any experience with Sedgwick Lifts?
Thank you.
