B.2.4 Physical Installation
B.2.4.1 Search-coils
Follow the instructions in
of this manual to install the mounting bar and coil triads of the
350 system.
Follow the instructions included in the 440 manual to install the mounting frame and the coil array of
the 440 system.
CAUTION
With drive current applied to the coils of the 440 system, large induced voltages
can appear across the coils of the 350 system. Later versions of the 350 search
coils (serial numbers from 570 and upwards) include diodes to protect them from
damage caused by these induced voltages.
If your system includes coils that have no diode protection (serial numbers below
570), you should ensure that there is a clearance of more than 0.75 metres
between the coils of the 350 system and the coils of the 440 system. Contact
Teledyne Limited for advice if necessary.
