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. -
Page 5: Intended Use
WRM-4 1.3. Intended use The turnout detector is intended for use in model railway layouts as specified in the instructions. Any other use is not in accordance with the intended use and will result in the loss of the warranty claim. Intended use also includes reading, understanding and following all parts of the instructions. -
Page 6: Operation Overview
(together with digital solenoid decoders). The WRM-4 detects the position of the drives of turnouts and signals with double coil drives without limit switching. As the position of the anchor in the coil is analysed, the detector also reacts if turnouts are shifted manually. -

WRM-4 3. Assembling the kit You can skip this section if you have purchased a ready-built module or device. 3.1. Safety instructions Mechanical hazards Cut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB. -
Page 8: Soldering Properly
WRM-4 tams elektronik 3.2. Soldering properly Use a soldering iron with temperature control, which you set to approx. 300 °C. Only use electronic solder with a flux. Never use soldering water or soldering grease when soldering electronic circuits. These contain an acid that destroys components and conductor paths. -
Page 9: Preparation
WRM-4 3.3. Preparation Put the sorted components in front of you on your workbench. The separate electronic components have the following special features you should take into account in assembling: Resistors Resistors reduce current. The value of resistors for smaller power ratings is indicated through colour rings. - Page 10 WRM-4 tams elektronik Transistors Transistors are current amplifiers which convert low signals into stronger ones. There are several types in different package forms available. The type designation is printed on the component. Transistors for a low power rating (e.g. BC types, BS types) have a package in form of a half zylinder (SOT-package).

Page 16: Functional Test
4.2. Functional test Before mounting the WRM-4 in the layout it is recommended to perform a functional test, especially when you have assembled the detector from a kit. Perform the functional test with one point and two lamps by connecting them according to the details given in the following sections and the diagram. -
Page 17: Connecting Lamps Or Leds
With LEDs you have to observe the polarity, otherwise they do not light. Connect the cathodes (-) to the outputs of the WRM-4 (A1a bis A4b) and the anodes (+) to the return conductor for the outputs (RL). With standard LEDs the longer connecting pin is the anode (+). -

WRM-4 5. Connecting subordinate circuits The WRM-4 evaluates the income signals against earth. Thus you can connect the outputs of the WRM-4 to: the inputs of subordinate electronic circuits with a current consumption of max. 250 mA;... -
Page 20: Connecting Subordinate Circuits Via A Relay
In addition you should connect a free-wheeling diode (e.g. 1N400x) in parallel to the relay in order to avoid damages to the outputs of the WRM-4. Pay attention to connect the anode of the free-wheeling diode (+) to the output of the WRM-4. -
