Up to four Servos can be connected to a servo decoder and operated independently
of each other. The servo decoder works like a turnout decoder and in a digital
system is assigned a solenoid address for each servo. By using the digital system’s
solenoid control the servo can be brought to two stop positions. The servo decoder
operates with all DCC and Motorola Digital systems. In addition the decoder has 4
switched outputs which operate in parallel with the respective servo. This is a
change over switch which changes its state with the servo position. In this way
switching tasks are done e.g. changing the polarity of turnout frog or cutting the
track power at signals.
The servo’s stop positions for the two solenoid states “red” and “green” can be
configured independently. The speed at which the servo moves between the two
end positions can also be configured. For special applications each of the
connected servos can be stopped at two additional stops by an additional solenoid
address. This way mechanical items like water cranes can be moved between four
positions via two solenoid addresses.
For optimal use of the change over switch, which is operated with the servo motion,
the time at which the switch is to change over can be configured. The change-over
can occur at the start, end or middle of the movement. The switching time can be
independently configured for each servo movement.
1 Address, both stops and the rotating speed for each servo are separately setup
with simple key programming from Motorola and DCC centers.
When using a DCC center like the Intellibox all parameters can be programmed by
CV programming. That way, 2 addresses, their stops, the rotating speed and the
rocker function can be separately setup for each servo.
