Abstract
PURPOSE: To improve reliability, by detecting abnormality rapidly and precisely by mounting a monitor circuit and by continually operating a check relay in an alternating current-like condition by counter output obtained by dividing specified frequency.
CONSTITUTION: When pulses Cp enter a counter DC2 through a release contact of a relay 1R, the pulses are frequency divided to 1/n, a transistor Tr2 is switched by the output of the divided frequency and a relay CKR is operated in an alternating current-like condition through a transformer T and a rectifier RF. The output of the DC2 becomes to the input a of a NOR, its level repeats "H" and "L", but output c becomes to "L" because input b becomes to + when the 1R is under a release condition, a Tr3 is in OFF and a relay TGR2 is reset. The DC2 counts the output pulses tg of a speed generator, its output becomes to "L" when value reaches n, the Tr3 is in ON because the output c of the NOR becomes to "H" and the TGR2 is set. Reliability can be improved because abnormality is detected by such functioning.
