If light function (f0) is switched off the crane hook can be controlled with the speed control. When light
function (f0) is switched on you can control the trolley with the speed control. The adjusted speed step
remains after switching the light function. If the end positions should be reached without having
stopped the relevant motor the motor output is automatically switched off (overload protection).
Note: The overload protection automatically switches the motor output off whenever the end positions
are reached, if the motor is not stopped.
By reversing the travel direction the speed is set to 0 and the motor output is reactivated (emergency
stop without starting/brake inertia).
If outputs A1 to A4 have loads attached they can be switched by special function keys f1 to f4. The
loads on A1 to A4 must operate on approxi20V. The key terminals are not functional in the
digital operations.
Programming
In factory default state all decoder options are changed using configuration variables (CVs) according
to the DCC standard. The decoders can be programmed by an Intellibox, DCC Centre and Motorola
Centre.
Programming with the Intellibox
Irrespective of the format to be driven later we recommend that the decoder be programmed via the
programming menu for DCC decoders.
The Intellibox supports DCC programming with a simple input menu. Long addresses do not have to
be laboriously calculated, they can be entered directly. The Intellibox automatically calculates the
values for CV17 and CV18.
For the exact process please read the appropriate chapter in the Intellibox manual.
Special case Motorola Locomotive addresses 80 to 255
In Motorola format the Intellibox supports an address range 255. Addresses 1 to 80 can also be
programmed easily using DCC programming mode. If an address above 80 is to be programmed, it
must, however, be done as described in the chapter “Programming with a Märklin Centre”.
After this programming technique CV 1 will be set to 0 and the decoder will use the Motorola address
higher than 80.
Programming of long Addresses without Programming Menu
For programming with a centre which does not support programming with an input menu, the value for
CV17 and CV18 must be calculated. Here is an example for programming the address 2000.
x
Divide the addresses by 256 (2000:256 = 7 remainder 208).
x
Take the result (7) and add it to 192.
x
Program this value (199) into CV17.
x
Program the remainder (208) into CV18.
x
Important
: Set Bit 5 of CV 29 to 1, so the decoder uses the long address.
Calculating the CV value
With CV29 and CV49 various characteristics of the decoder may be established.
The required values are easily calculated using the CV table and simple addition.
Example CV 49
Motorola off
Value = 1
DCC on
Value = 0
f1 toggle A1/A2
Value = 64
+20V on RL
Value = 0
The Sum of all values is 65.
This value is programmed into CV 49.
