Claim 0:
1. A coiled tubing injector for running coiled tubing into and out of a well in a hydrocarbon-bearing formation, the coiled tubing injector comprising:
a coiled tubing injector head including a base and a gripping mechanism configured to grip the coiled tubing running through the base and to advance and retract the coiled tubing;
a control system including
a coiled tubing indicator disposed between the gripping mechanism and a blowout preventer coupled to a head of the well, to indicate a change from presence of the coiled tubing to absence of the coiled tubing,
a gripping mechanism control coupled to the coiled tubing indicator and operable to stop movement of the gripping mechanism, thus discontinuing movement of the coiled tubing in response to the coiled tubing indicator indicating the change from the presence of the coiled tubing to the absence of the coiled tubing;
wherein the coiled tubing indicator comprises an indicator arm moveable between a first position in which the coiled tubing is present and a second position in which the coiled tubing is absent.
