Claim 14:
15. The method of claim 14, wherein a reel feeds the coiled tubing to the injector assembly, one or more first hydraulic motors are operable to drive rotation of the reel, and one or more second hydraulic motors are operable to configured to drive rotation of the pair of endless drive chains and thereby longitudinally move the coiled tubing, the method further comprising:
providing hydraulic fluid for the one or more first and second hydraulic motors with a power source;
manipulating one or more valves via operation of a control console in communication with the power source and thereby selectively conveying the hydraulic fluid to the one or more first and second hydraulic motors; and
sending a command signal from the microprocessor to the control console to cease operation of the one or more first and second hydraulic motors when the real-time measured linear speed of the coiled tubing exceeds the predetermined linear speed threshold.
