6 Decoder-Installation
6.1 Preparation
Check if the locomotive is in perfect running order electrically and mechanically, prior to any mounting work.
Defects and dirt must be eliminated first. Pay attention to the instructions of the locomotive producer. Only
locomotives running smoothly in analogue mode, should be equipped with a digital decoder. New
locomotives should be run in at least 30 minutes in each direction of travel.
Before you start, insulate the motor and all its terminals completely against track connections (chassis,
collector slipper, etc.).
Both motor connections must be disconnected from the ground!
Further on, all condensers have to be removed, particularly those associated with the connections of light
and motor.
Fix the decoder with a double sided adhesive tape.
6.2 Check after the insertion
The first test should be executed in the programming mode (e.g. by reading out the address). In case of an
incorrect feedback (confirmation signal) to the central unit ("error"), please check again the correct
assignment of the connections respectively if the motor is really disconnected from the chassis electrically.
