WRM-4

1. Getting started

The instructions will help you step by step with the safe and proper assembly of the kit and
installation and use of your turnout detector. Before you start to assemble the kit or put the
turnout detector into operation, read this manual completely, especially the safety instructions
and the section on possible errors and their elimination. You will then know what you have to
pay attention to and thus avoid errors that sometimes can only be rectified with a lot of effort.
Keep the instructions in a safe place so that you can restore functionality later in the event of
any malfunctions. If you pass the turnout detector on to another person, also give the
instructions with it.

1.1. Contents of the package

1 kit WRM-4 (item no. 52-02045-01), containing the components listed in the parts list
( section 3.4.) and one PCB or
1 ready-built and tested circuit board WRM-4 (item no. 52-02046-01) or
1 turnout detector WRM-4 in housing (item no. 52-02047-01)

1.2. Accessories

To assemble the kit you will need

a soldering iron with temperature control and a thin tip and a deposit stand or a controlled
soldering station

a scraper, rag or sponge

a heat-resistant pad

a small pair of side cutters and wire strippers

tweezers and flat-nose pliers if necessary

electronic solder (preferably 0.5 to 0.8 mm diameter)
Connection cables
The use of stranded wire is recommended for making the connections. Stranded wires consist
of several thin individual wires and are therefore more flexible than rigid wires with the same
copper cross-section. Recommended cross-sections:

Connections to the turnouts and the power supply: > 0.10 mm²

Connections of lamps or LEDs: > 0.04 mm²
Display of the turnout position
To indicate the turnout position, you need 2 LEDs (with suitable series resistors) or small
lamps for each turnout.
Function test
It is recommended to test the detector´s functions before mounting it into the layout,
especially if you have built the module from a kit. For this you need a turnout and two light
bulbs.
