How the KeerPlus3 works
The functionality of the KeerPlus3
The KeerPlus3 works entirely based on current detection divided into three sections. Current detection
means that each section is detected along its entire length on power consumers such as locomotives or
carriages with lighting. In short, everything that consumes electricity.
As mentioned, the module uses three sections. As soon as the first section (S1) is activated by means of
detection, the module switches the second section (S2) and the last section (S3) into the same polarity as
S1. Subsequently section S2 is driven and as soon as the locomotive activates the last section S3, the
module immediately switches the S2 and the last section S3 to the opposite polarity. The first section S1
remains untouched so that it can be ridden again.
This works identically when the Reverse loop is driven from the other direction. In rest mode, the module
“sniffs” on sections S1 and S3 to a consumer. As soon as S1 is activated, the module converts S2 and S3
into the same polarity and switches the module at S3 together with S2. If S3 is switched first, the module
converts S1 and S2 to the same polarity and as soon as S1 is activated it converts S1 and S2 to the other
polarity. Because S3 then remains standing, a train can just enter it again.
