CONTROL SYSTEM FOR A ROTATION STATION FOR REMOTELY INSTALLING A MECHANICAL TUBE PLUG

摘要

A controller for an apparatus for installing a mechanical tube plug includes a controller (60) having a controller console (64) remote from the tube installation site and a solenoid assembly (62) located proximate to that site. The console includes switches and indicators for providing a rotation control signal to the apparatus. The solenoid assembly (62) includes a circuit for receiving a torque indication signal from the apparatus and an alarm circuit for setting the torque at a predetermined upper limit in response to a signal input at said controller console (64). The circuit operates to terminate rotation control and disable the apparatus when said limit is reached. Other features of the controller are also disclosed.
