5.7 Diesel and Electric engines

Diesel motor sound, Turbocharger sound
Thyristor sound, Electric motor and Switchgear sound
Diesel and Electric engines have certain commonalities and are therefore described in the same
chapter: Diesel-electric propulsion systems have sound components (sound sequences) from both
areas. On the other hand, the separation of "Basic settings" and "Load dependence" (as with the
steam engines in the previous chapters) is not practical.

5.4 "Basic settings independent of powertrain"
This CV determines the reaction of the diesel
sound to load, acceleration, inclination:
Diesel-hydraulic engines – higher and lower
rpm's and notches
Diesel-electric engines – cruise/idle rpm
Diesel-mechanical – shift points.
0
= 0: no influence, motor rpm changes with speed
= 1 to 255: minimum to maximum influence.
NOTE: It is highly recommended to perform the
automated test run with CV #302 = 75 first (see
chapter 5.3).
Bit 1 = 1: DIESEL: Drive off immediately even if
idle sound has not finished playback.
0
Bit 2 = 1: DIESEL, ELECTRO: After short stops,
wait for idle sound before driving off.
Bit 4 = 1, bit 7 = 1: see STEAM.
Bit 0 = 1: SPECIAL MX648: If function output FO1
is used for automatic control of external energy
storage. This was an OEM feature. For more de-
tails contact www.zimo.at
Bit 1 = 1: DIESEL-MECHANICAL: No RPM
increase when braking (see CV #364).
Bit 2 = 0: RailCom speed (kph) feedback in the
"old" format (for MX31ZL, RailCom ID 4).
= 1: RailCom speed (kph) feedback in the
current format (RailCom ID 7).
Bit 3 = 1: "Looped" driving sounds (i.e. idle sound)
will be faded out when switching to a
different speed step in order to shorten
the sounds.
Bit 4 = 1: Steam chuff frequency increases slower
at high speed (non-proportional)
Bit 5 = 1: Braking (even by just one speed
step) causes the motor and turbo loader
sounds to decrease by on sound step.
Bit 6 = 1: Thyristor sound volume may increase
when braking (even if the volume is

Defines a function key (F1 – F28) which switches
between two sound types that is, between the se-
lected sound in CV #265 and the next one in the
list. For example:
- Switch between two modes of operation (light
train / heavy train) or
0
- Switch between electric and diesel propulsion of
a multi-system engine; typical case: Sound project
for RhB Gem.
Bit 0 = 1: Switches between sound collections at
stand-still even if sound is ON.
