Page 3: ...the lane to change polarity There are two types of circuits the short circuit method and the current detection solution The KeerPlus3 only uses the current detection method In this manual we explain how the solution works and how it can be applied to your model railway I wish you a lot of ease of use with the KeerPlus3 if you have suggestions for improving the product or a critical note Let me kno...

Page 5: ...ections The advice is to use approximately 1 5x a locomotive length In theory a length of 5 centimetres would be enough to generate a good detection However practice shows that contact between the rails and the wheels is sometimes not guaranteed To make the Reverse loop sections work reliably and stably we recommend using a longer length for this Mounting The KeerPlus3 has 4 mounting points It is ...

Page 8: ...he sections otherwise the module will switch incorrectly Finally it is important that all sections on both sides in the two rails are interrupted You can do this by using rail welding or cutting the rails The sections are therefore not allowed to make contact in both A and B There are 3 LEDs on the module that show the polarization status per section If the LED is off the polarization relay of tha...

Page 10: ... The reason that it should be the other polarity if the person you offer on the busy reporting module is because the busy reporting module in this case does not feed the section as normal but only detects it You connect this dcc polarity to the terminal 9 with a carbon resistor with the value 10 kOhm 10 000 Ohm Only this value will generate a detection on your busy reporting module The resistor ca...
