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.
Attention:
When a component gets hot, disconnect the detector from the voltage supply immediately! Risk
of short cirvuit! Check the assembly.
Perform the functional test for the four function areas one after another:
connecting one point to the detector´s inputs (a and b);
connecting one lamp to each of the two corresponding outputs;
connecting and switching on the voltage supply;
switching the turnout manually into both positions. The two lamps should light alternately.
4.3. Connecting the turnouts
Connect the inputs of the turnout detector to the turnouts. Mind the correct assignment.
