Page 4: Introduction
Introduction HG G-21934 Introduction The herein described system is especially suited for vehicles working in an outdoor environment. The electronic unit within the antenna casing is fully submerged in a seal- ing compound. All important adjustments are carried out via sealed potentiometers. -
Page 5: Components And Operation
Components and Operation HG G-21934 Components and Operation 2.1 Components in the Ground The accuracy of the system is effected by large metallic objects on the ground metallic reinforcements within a close area of the guide wire. Inductive loops have a large influence on the system's accuracy, (such as those caused by steel mating). -

Components and Operation HG G-21934 2.2 The Installation Components 2.2.1 Loop Adaptor HG 94210 The loop adaptor is contained within an aluminium casing, size 120 x 122 x 91 mm. It is fitted with two PG plugs, one for the RG 213 coax cable from the generator and the other for both ends of the loop conductor 2,5 mm². -

Page 11: Error Influence
Components and Operation HG G-21934 From this we see, that the rate of climb of the difference voltage course is dependant upon the installation height of the antenna, the size of the maxima are also proportional to the current rate used. - Page 12 Components and Operation HG G-21934 More often in large installations there are also neighbouring loops in operation. As the generators are not phase rigidity interconnected, they make themselves noticed as suspensions within the field. To avoid this it is possible to set the fre- quencies with ±50 Hz steps.
