3.3.3. Hook-Up of a Power Buffer
A power buffer may be installed to improve the operational reliability. The buffer connects to “Dec+“ and “Dec-“.
The charging current must not exceed 500 mAmps.
Analog operation must be disabled with a power buffer connected to the eMOTION XXL Decoder otherwise the
decoder recognizes the power buffer as an analog power supply (CV29 bit2).
The power buffer must be switched off during programming.
The MASSOTH Power Buffers (#8151001 or #8151501) are switched off automatically during programming if
you connect the white control line to “A5“ with the power buffer control function activated in CV118 = 31. Then
the A5 output cannot be used for other purposes.
3.4. Motor Output
Depending on which digital system utilized different speed steps may be used. The more steps are used the
smoother the locomotive responds to the throttle. In Garden G-Scale 14 speed steps are used and 28 speed
steps are recommended if supported by the digital system.
•
The direction of driving (including the direction related functions) can be reversed by setting CV29 - bit0
accordingly.
•
Three settings of speed control are available:
14 speed steps (CV29 – bit1 = Off)
28 speed steps (CV29 – bit1 = On)
128 speed steps (is detected automatically)
Using the eMOTION XXL with LGB
®
MTS I or II requires a 14 speed step setting. This is the factory default
setting of the decoder.
Several CV settings in the eMOTION XXL Decoder influence the acceleration and deceleration characteristics
of the locomotive. The acceleration/deceleration characteristic is defined by 2 CVs:
•
Acceleration delay (CV3)
•
Deceleration delay (CV4)
The time lag between speed 0 and the maximum speed (or reverse) is 0.5 sec if the setting is “1”, maximum
possible is 128 sec (setting “255”). Simply divide your desired time delay by “2” to acquire the respective CV
setting.
