Abstract
A controller for an apparatus for installing a mechanical tube plug includes a controller having a controller console remote from the tube installation site and a solenoid assembly located proximate to that site. The console includes switches and indicators for providing a rotation control signal to the apparatus. The solenoid assembly 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. The circuit operates to terminate rotation control and disable the apparatus when said limit is reached. Other features of the controller are also disclosed.
