16 Construction The ISR pneumatic spring control system combines the proven pneumatic springs with a new contactless electro- pneumatic controller, where sensor and control valves are combined into one compact assembly, and integrated into the pneumatic spring. A controller with manual operation or PC connection allows the selection of the following settings: • Levelling of the system (horizontal installation) • Tracking the position of each support (operating height) • Tolerance choice of height and reset accuracy • Delayed or suppressed reaction with dynamic action • Monitoring and documenting The design implements a compact design with low cost modules. A sensor for non-contact level detection is integrated in the pneumatic element. As a result, separate sensing of the machine height is unnecessary. In addition, valves for filling or emptying the interior chamber are arranged as lifting and lowering valves within the pneumatic spring. The outlet air can be discharged feely or guided (e.g. for clean room requirements). The system comprises three controlled pneumatic supports (masters) and further pneumatic supports (slaves) without con- trol that may be engaged for load distribu- tion. The system includes a controller that records data from sensors on the opera- ting height or level of each support, and compares this information with adjustable set-point valuers. A user-specific tolerance can be pre- set for avoiding overreactions. The individual zero positions of the three controlled supports are adjusted with a potentiometer; the system is levelled at the same time. Menu-driven software allows the selection of resetting accuracy, height tolerance, switching and response times as well as monitoring. ISR System
