Hall Sensor IC
After ben ha-fitted a wheel sensor and connected, you need to tell the decoder
that it should use this. Ex factory, all LokSound decoders are set 5 so that they
use a clock electronically generated.
Be det in CV 57 to 0, so that the wheel sensor verwen-. In CV 58 defines how
many sensor pulses of de- coder to receive before it triggers a burst of steam. If
CV 58 = 1 is set, is achieved at each pulse a steam off. Depending on the
magnet and the sensor is twice as much as may be desired. In this case CV
should be set 58 = 2nd Values> 2 are only useful for Getriebeloks.
Make sure that the Radsensoreingang is active but not connected as output
AUX9. To this end, H0 decoder in CV 124 Bit 4 must be set for LokSound!
6.11.1. HALL Sensor IC
A Hall sensor is an electronic circuit (IC) which is responsive to a changing
magnetic field. The HALL IC available can be installed in locomotives very
simple, because the distance between IC and magnet is not critical. A frequently
used Hall IC is the TLE4905 by Siemens / Infineon to which there are also many
compatible types. The three terminals of the ICs to be connected to the sound
decoders as it is shown in Fig. 30th Obstruct you pelachse four miniature
magnets on the inside of a copper and ensure that the magnets rotation pass in
the Radum- HALL IC and thus trigger the impulse. At 3 Zyinder locomotives you
need either 3 or 6 magnets off pending on the cylinder assembly.
6.11.2. reed contact
If you is too expensive to connect a Hall sensor IC, you can also use miniature
reed contacts. This advertising to connect to the decoder with only two lines.
However, these are very sensitive and require stronger magnets to trigger. In
addition, the installation position of the reed contact must be considered.
