The Built-In Diesel Sound Effects Circuit - Märklin V 200 BR 220 Gebrauchsanleitung

2
Operation
Of the functions f1 to f4, the function f1
is on continuously when operating
the locomotive with conventionel
AC power. The other functions
remain off. For that reason this loco-
motive will always operate with the
engineer's cab lighting turned on
without diesel motor sound effects
in AC power operation.
2.5.5 Operating the locomotive
on direct current
Märklin does not offer DC power
packs for 1 Gauge models. Suitable
DC power packs are those with a
maximum current of ±18 volts.
Direction reversing is done by rever-
sing polarity. The manufacturerís
instructions for a particular make of
power pack will give directions on
how to use it to operate a locomotive.
20
Tip: H0 DC power packs supply a
maximum voltage of ±12 volts. This
locomotive reaches its full potential at
±16 volts. H0 DC power packs can
therefore be used only with limitations.
In operation with direct current the
headlights change direction with the
direction of travel and are on all of
the time. The intensity of the head-
lights depends on the speed of the
locomotive.
Of the functions f1 to f4, the function f1
is on continuously when operating

DC power. The other functions

2.6 The built-in diesel sound
effects circuit
This sound effects circuit was tuned
at the factory for this locomotive.
The following settings can be changed
by you:
• Total volume.
• Volume relationship between the
diesel sound effects and the
locomotive's horn.
• Relationship of the sound effects
circuit to the maximum speed set
on the digital decoder.
When changing the maximum speed
on the locomotive decoder (=> Setting
the Running Characteristics) the sound
effects circuit must also be adjusted
to the new conditions. No adjust-
ments in the sound effects circuit are
required when changes are made in
the acceleration and braking delay.
The adjustments to the sound effects
circuit should be checked by opera-
ting the locomotive. The Control Unit /
Mobile Station / Central Station must
be used to control the locomotive.
We recommend setting up a small
test track (circle or oval with a mini-
mum radius of 1,020 mm or 40-5/32")
or a test stand with a Control Unit /
Mobile Station / Central Station
connected to it. We recommend
setting the acceleration and braking
delay at the minimum value during
the adjustment work.
Important: You can carry out adjust-
ments to the sound effects circuit
your-self. Damage to the potentio-
meters on the circuit board caused
by too much force applied to them
are not covered by the warranty.
