7 Setting the track voltage
The limit of the track voltage of the LV103 can be set. However, the
track voltage may actually be lower than the set value, depending on
the voltage and the capacity of the transformer supplying the power.
Depending on the gauge for which the LV103 is used, changing the
factory setting of the track voltage may be advantageous (terminals J
and K). Larger gauges in particular, are often operated with slightly
higher voltages or if you want a lower output voltage for gauge N. If
possible, the transformer voltage should be adjusted to the desired
track voltage. A transformer voltage which is too high leads to an
unnecessary loss of heat in the amplifier which in turn leads to an early
switch-off before the maximum output voltage is reached.
The factory setting for the output of the LV103 is 16V; you can choose
a range between 11V and 22V.
If you have several supply areas on your model railway layout, you will
have to set the track voltage (output voltage) for the amplifiers in use
to the same value.
"PoM", "Programming in operational mode" is used to set the track
voltage. Before making the settings, you should familiarise yourself
with using PoM with your manual control LH100, LH101 or LH90.
The LV103 must be connected to terminals C and D in order for the
track voltage to be set. The command station and the amplifier LV103
must be switched on.
Proceed as follows:
Select any locomotive address on the manual control (
Don’t
worry:
If a locomotive with the address used above is placed on a
track while you are setting the voltage, its settings will not be
affected, since CV7 can only be read in the locomotive decoder,
but not changed.)
Change over to "PoM "
Select CV7.
Program the value 50 into CV7. This switches the LZV100 into
setting mode; the LED of the LZV100 shows a double-flash.
You have 15 seconds to program the value for the desired output
voltage (compare below) into CV7. The LED will shine constantly
and the track voltage is altered.
