Abstract

PURPOSE:To prevent the power source of a work station from turning off owing to malfunction when a center machine and work station are in a link-on state, by turning off the work station power source when linking-off is possible and by inhibiting it from turning off when it is impossible. CONSTITUTION:The on-off signal for power source switch 11 of the work station is outputted to power source controller 12 and inverter 13. Power source controller 12 has enable terminal E and only when a ''1'' signal is inputted to terminal E, power switch 11 is turned off to output a PWOFF signal turning off the work station power source, turning on a relay that turning off the power source. Flip-flop 14 has an L-ON signal arriving at set terminal S when the center machine and work station are in the link-on state or an L-OFF signal at reset terminal R when in a link-off state. Then, mask-out signal UM is inputted to set terminal S of flip-flop 17, and mask signal M to reset terminal R.
