Title: SYSTEM FOR LINE MONITORING IN AN ENERGY CHAIN
Abstract:
The invention relates to a system for monitoring the state of a cable (70), which is guided in an energy chain (1) between a base and a movable driver element. The movable energy chain forms a movable run (1B) at a driver element (2), a resting run (1A) at a base (4) and, between the two runs, a deflecting bend (1C). A monitoring device having at least one indicating element (64) at the energy chain (1) evaluates an indicating-element signal and monitors whether an error state occurs. The indicating element has two electrical indicating conductors (62A, 62B) guided by the energy chain, which indicating conductors extend along the movable run (1B), and the monitoring device comprises a measuring circuit for resistance measurement or conductance measurement (65...69). One end point of each indicating conductor (62A, 62B) is connected to the measuring circuit and the other end points of the indicating conductors (62A, 62B) are short circuited such that the indicating conductors (62A, 62B) form a measurement loop (62).
