Abstract:
A reusable apparatus for disabling an actuator of an industrial control, comprising:a) an elongated shackling member adapted for interaction with an actuator of an industrial control to prevent operative movement of said actuator;b) a housing for fixedly retaining the distal end of said elongated shackling member and selectively, lockably retaining and releasing the proximal end thereof in said housing;c) circuit means for detecting when said proximal end of said elongated shackling member is lockably retained in said housing and when said proximal end of said elongated shackling member is released therefrom;d) tamper detection means, operatively connected to said circuit means, for indicating when said shackling member has been cut or stretched beyond a predetermined limit; ande) signal generation means disposed within said housing and operatively connected to said circuit means and said tamper detection means and adapted for generating an inaudible, invisible signal responsive to a predetermined state of said circuit means and said tamper detection means.
