44、e Requirements and Test Procedures RATIONALE Exit side immobilization can provide a more convenient method of allowing personnel remote from the horizontal directional drill to disable drill string movement without having to travel to the drill or to depend upon voice communication. Exit side immobi
45、lization is not a substitute for drill team training, organization, two-way communication and established procedures, but is a supplement to them. This appendix provides designers of wireless exit side immobilization devices guidance by providing definitions, performance and test criteria. Criteria
46、for the use of an exit side immobilization system are beyond the scope of this document. Means of overriding the immobilization system by design may be provided. A.1 SCOPE This guideline specifies minimum performance and test criteria for exit side immobilization of the drill string. It is not inten
47、ded to define the only acceptable means of immobilization of the drill string. A.2 DEFINITIONS For the purpose of this guideline, the following definitions apply: A.2.1 Exit Side Control Control device used at the drill string exit side for communication with the machine control interface to immobil
48、ize the drill string. A.2.2 Receiving Unit Control on machine for receiving signal from the exit side control for either immobilizing or enabling drill string movement and providing status indication. A.2.3 Signal Transmission Range Reliable communication distance specified by the manufacturer. A.3 GENERAL REQUIREMENTS An immobilization system shall allow at least one person distant from the machine to immobilize the drill string. Once the drill string has been immobilized, the system shall assure that drill string movement cannot r
