Bauer LINESTAR 9000 Operating Manual page 33

By means of the transformer installed, the oscillator box can either be connected to a 230V AC / 50Hz supply line
or it can be supplied directly by a battery of 24V DC (2 x 12V DC). A voltage of 24V with a frequency of 1,5KHz is
supplied directly to the cable laid below ground. The magnetic field generated thus is detected by the steering
antennas and the voltage induced is evaluated in the so-called track unit.
Important information:
At first putting into operation, the below ground cable will generally be connected to the "long connection" terminal
of the oscillator box. If the system works duly, the green LED will be lit.
First putting into operation is exclusively carried out under the presence of a BAUER technician or of an authorized
dealer and it must not be carried out by unqualified personnel.
