märklin #600401 MAXI-Delta decoder for BR140

This is a result of my study for #600401 MAXI-Delta decoder for BR140.

Pin assign of connectors on the decoder are:

<LICHT> - both connector are connected in parallel.

1. to light circuit
2. to light circuit

<MOTOR> - both connector are connected in parallel.

1. rail
2. motor
3. motor
4. rail

<Blue connector> - for #56560 sound circuit.

1. NC
2. NC
3. Speaker
4. Speaker
5. Motor (internaly connected to motor circuit)
6. Motor (internaly connected to motor circuit)
7. Gnd (internal)
8. Engine sound Start/Stop (permanently connected to gnd.)
9. Horn on/off (to <REEDKON.> #2)
10. Horn pitch low(off)/High (to <REEDKON.> #4)
11. NC
12. +Ub (internal) - switched by 'function switch' on back side of PCB.
13. NC
14. NC

<REEDKON.> - connector for reedswitches.

1. Gnd.
2. Horn on/off of #56560
3. Gnd.
4. Horn pitch low(off)/High

If #1-#2 short, Horn function activate. If #3-#4 short Horn pitch is high.

<LAUTSP.>

1. to Speaker
2. to Speaker

Combination of 'direction arrow' on 6021 CU and output.

All voltages are measured between internal ground.

Voltages of <LICHT> is depends on voltage of <MOTOR>.
