Page 4: The Workings Of The Keerplus3
The operation of the KeerPlus3 The functionality of the KeerPlus3 The KeerPlus3 works entirely on the basis of current detection divided into three sections. Current detection means that each section is detected over its entire length for power consumers such as locomotives or carriages with lights. -

Assembly The KeerPlus3 has 4 mounting points. It is recommended to mount the board at height because of the heat generation of the voltage regulator. Preferably with the components at the top. -

KeerPlus3 manual │ version 3 - 2022 Connecting the KeerPlus3 Supply voltage The supply voltage to be offered to the KeerPlus3 can be provided in three different ways: 1. DC voltage 12-16 VDC 2. AC voltage 12-16 VAC 3. DCC Signal The DCC signal refers to the Track Output of the central unit. -
Page 8: The Loop
So perform both connections, otherwise the KeerPlus3 will not work. You can also loop the DCC signal to the power input. The KeerPlus3 does not draw power from the DCC input because one has other ways to power the module. The Turner loop In the image above, you can see the three sections drawn with their corresponding connection to the module. -
Page 9: Switching Outputs
KeerPlus3 manual │ version 3 - 2022 Switching outputs At the top are 4 screw terminals (9 to 12) which switch based on current detection. As soon as current detection is present in a section, a second relay will switch between these terminals. There are three relays in total, one for each section. -

However, what is important is that the other wire (DCC-A on the diagram) is brought to terminal 9 on the KeerPlus3. The reason it has to be the other polarity as the one you offer on the busy signal module is because in this case the busy signal module does not feed the section as normal, but only detects it. -
Page 11: Frequently Asked Questions
2: You swapped S1 and S3 I get no busy signal on the busy signal module Solution 1: You have offered the same polarity on the KeerPlus3 terminal 9 as on the COM connection of the busy signal module Solution 2: Your resistor has the wrong value It gives a busy signal on S1 while the locomotive is running in S3 .
