Abstract (en)
[origin: EP0523951A2] An actuator apparatus for a downhole tool, such as a downhole shut-in tool, comprises mechanical actuator means (132) for actuating said tool; drive means (134), operably associated with said mechanical actuator means, for moving said mechanical actuator means; abutment means (156) for abutting said mechanical actuator means to limit movement thereof and thereby define at least one position of said mechanical actuator means; and control means (164) for controlling said drive means (134), said control means including and being responsive to a load sensing means for sensing an increased load on said drive means when said mechanical actuator means abuts said abutment means. <IMAGE>
