Hydraulic lift question. Hoping someone knows some basics on hydraulic lift activation. My dinghy lift is 1992 vintage.
The remote control no longer functions and the control panel is old relay technology. Lift is hydraulic, simple function in/out & up/down. The cylinder travel is approximately 40 inches in/out and 30 inches up/down. The travel both ways are tied into proximity probes that must be met in order to allow the activation of up / down or in / out. IE Lift must be all the way out and prox probe met before up or down can be activated. My question is on retrofitting the current controller (12 V) with something more up to date. Do I simply require a new 4 way activator control mechanism to replace the current relay system or is it more complicated due to the prox probe configuration? If nobody has knowledge perhaps you can steer me in the right direction.
