3.3
Consumers and low voltage outputs
“Consumers” (or function elements) is all equipment connected to the function outputs Flf,
Flr, FO1-FO13. Mostly, this is lighting equipment (light bulbs and LEDs), but also positioning
magnets, small motors, relays, etc.
Each consumer (light bulbs, groups of light bulbs or other) is always connected to the corre-
sponding function output (negative) and to one of the up to 4 positive poles (positive):
- Positive pole - full track voltage: the directly commutated driving voltage; depending on the
stabilization of the digital command station and track voltage, this is relatively unstable, i.e.
oscillates with the driving voltage.
- Low voltage - 10V: this is the voltage mostly used within the decoder to produce sound. AT-
TENTION: too much or volatile consumption by the consumers at the 10 V source can impair
the sound quality. A short circuit on the 10 V output can damage the decoder. Therefore, on-
ly use it, if there is no other possibility (i.e. the adjustable low-voltage output is already in
use).
- Low-voltage - 5 V: this voltage is provided for servos and consumers, e.g. also for common 5
V light bulbs.
Only in V-types!
- the adjustable (= variable) low-voltage: via a coding switch on the decoder PCB, which leads to
the space between FO12 and FO13, the low-voltage can be adjusted in the following steps: 1.5
V, 6.5 V, 10V, 15V.
Only in V-types!
NOTE: Rather use a low-voltage source than reducing the voltage per software (dimming
with CV #60), because dimming uses PWM reduction (full voltage impulses with a corre-
sponding duty cycle), which can damage light bulbs (not LEDs).
See chapters concerning decoder configuration (CVs) for function mapping, function ef-
fects, electrical couplers (systems by Krois, Heyn), etc.
Note to decoders MX696:
The MX696 does NOT have the (definite) 5 V low-voltage. If needed (e.g. for servos) the ad-
justable low-voltage (only MX696V) has to be used.
Note to decoders MX696N (non-sound version):
Those provide a 6 V low voltage output (instead of the 10 V low voltage of the sound decod-
ers). Due to this, servos can be supplied directly by the decoder.
3.4 Special connections for smoke-fans
Those outputs are used to control fan motors of clocked smoke generators, as they are
used in many modern locos.
The special feature of these outputs (in contrast to the “normal” function outputs) is the
possibility to brake the motor. This inhibits the motor from rotating after a current impulse,
whereby the steam-clocking gets stronger and more accentuated. The outputs are de-
signed for a 5 V motor and for a load capacity of up to 100 mA continuous current (the
start-up current may be higher).
The decoders MX695, MX696 and MX697 only have one fan output.
3.5 Servos
The MX699 provides 4 connections for common servos, which can be used for couplers,
pantographs and other mechanical equipment.
ATTENTION: Servos of different manu-
facturers all have three wires, but the or-
der and colors of the wires differ.
See chapter concerning decoder con-
figuration regarding allocation and
setting of the servos.
5V supply for servos is only available in
V-types. The control wires on the other
hand can be used in all types of the
MX695; if needed, the 5 V supply has to
be provided externally.
The 5 V supply for servos is only availa-
ble in the MX695KV, MX695LV and other
V
– type models!
The control wires though are usable with
all sound decoder versions; if necessary,
use an external 5V power source to power the servo.
