Fig. 4.5 Typical vertical testing arrangement 



The cable which attaches to the sensing head has two 9 

 pin connectors and one 5 pin connector. The 9 pin connec- 

 tors connect to the receptacles on the side of the head 

 and the 5 pin connector to the arm of one wheel. The 

 cable should be routed as per Fig. 4.6 to allow the head 

 to be installed on the rope when the connectors are 

 attached.
