ABSTRACT:
A safety system for use with an apparatus lowered into a well includes a power supply and a controller that monitors at least a predefined condition of the apparatus. A switch blocks power from the apparatus until the predefined condition is present. A test system includes a test device that generates a signal having a predetermined characteristic (a certain frequency, for example). A controller detects the signal and enables performance of a test operation when the signal of the predetermined frequency is present.
