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
