Interlock apparatus for fitness equipment comprises a microprocessor 105 receiving grip signal inputs from grip sensors (101A, 101B) mounted on a load-bearing component of the fitness equipment. Signal conditioners (103A, 103B) provide noise filtering, signal debouncing and digital inputs for the microprocessor. Grips status monitors (106A, 106B) provide grip status signals used by microprocessor 105 to determine the validity of the grip signals. Microprocessor 105 provides validity criteria which changes depending on the grip status inputs. The apparatus detects sensor connection changes and abnormal sensor and circuit operation and modifies logic functions to improve the capability and reliability of safety locks and brakes on the equipment. |
