The red LED goes out again although the programming bu;on has not
been
pressed again.
Some central units have the problem that aJer pressing the programming bu2on of the DR4024, the red LED goes out again shortly aJer the programming mode
has been ac1vated and the DR4024 automa1cally terminates the programming mode.
This happens if the locomo1ve with the address 9999 has not yet been ac1vated in the central sta1on. This can be easily avoided by always "ac1va1ng" "the loco-
mo1ve" with the address 9999 before pressing the programming bu2on of the DR4024.
In order to avoid the red LED ex nguishing, please observe the following procedure for POM programming:
1.
Define a locomo1ve with locomo1ve address 9999 (DCC, 128 speed steps) in the central/mul1 mouse or app.
2.
Ac1vate the "locomo1ve" with address 9999 in the control panel by switching the ligh1ng on and off again (F0) .
3.
Press the programming bu2on on the DR4024 only now. The red LED will now glow con1nuously to indicate that the DR4024 is in the
programming mode.
4.
Now start to change the desired CV's via POM (locomo1ve address 9999).
5.
To exit the programming mode of the DR4024, the programming bu2on must be pressed again.
The red LED goes out and indicates that the programming mode has been terminated.
