Abstract
An electromagnetically-controlled flat knitting machine has a supervising system for checking the functional readiness of a setting magnet of the machine. The supervising system comprises a microprocessor with a detecting and signalling device, and a detector for measuring closed and open circuits. Such measurements are collected periodically from the microprocessor through an intermediate unit and are signalled on the signalling device. The individual setting magnets can be checked for functional readiness both in the case of a stationary as well as a running machine without these having to be specially actuated (i.e. energized) for this purpose. To this end, a direct voltage of an intensity less than the response voltage of the winding thereof is applied to the setting magnet concerned. A measuring resistance is arranged in a conductor to the setting magnet energized by the auxiliary direct voltage, and the aforesaid intermediate unit is connected to an analogue to digital converter whose input is connected to the measuring resistance.
