If sensor 3 was selected and one of the sensors was ‘dark’
(indicated by ‘H’) the display would look like this:
H1L
When a sensor is covered (‘in the dark’) the test display for
that sensor should read ‘H’. When the sensor is lit you should
see an ‘L’ in the test display. For the unit to power up
properly both sensors should be lit (displaying ‘L’). If you are
getting an ‘H’ for a sensor, try shining a flashlight on the
sensor to see if it switches to ‘L’. If this works then you
should either add some additional lighting to your layout at
that point or move the sensors to a better lit location. If you
have marginal light at this location you can sometimes get the
sensor to work if you push it up a little further through the
roadbed (do not exceed the railhead height!).
If the lighting appears to be OK but a sensor is still ‘in the
dark’ dismount the sensor pair and inspect the connections
between the cable and the optic, and the cable and the
connector. Also look to see if the cable itself has been cut
along its length. If you have a damaged sensor assembly
contact TCS Inc. for technical assistance.
Another problem that can occur is the unit powers up correctly
but a train does not trigger the sensor properly. This can, on
rare occasions, be caused by too much light (especially on the
larger scales). It can also be caused by a short circuit in the
sensor cable assembly. To check to see if there is too much
light, put the unit in test mode as outlined above, and cover the
