Input for actual speed value with nominal tacho voltages
from 10 to 180V.
For hiqh nominal tacho voltages
(= 60V)
the setting sensitivity of the
trimmer,
which is
used as an attenuator,
can be r&3uced by soldering a
series resistor R 101 instead of
the nornlally used
wire
bridge.
C 101 must be removed in this oase.
The resistance of R 102 can be determined according
to the following equation:
