LEVEL CROSSING MODULE FOR LED SIGNALS LCS2-CA
The BLOCKsignalling LCS2-CA module detects trains using an infra-red sensor
mounted under the track. When the train passes over the top it triggers the
operation of attached warning lights.
Automatically detects trains using an infra-red sensor mounted below the
track bed
Operates attached yellow and red leds on level crossing signs (not included)
Once train has cleared the sensor, the leds automatically stop operating
Built-in programs to cover most UK and continental crossing styles
Requires a 12V DC Power Supply

- Page 2 Introduction Model railway layouts often incorporate a level crossing, and the LCS2-CA module is designed to add realism to these crossings with automatic detection of an approaching train, which triggers the operation of led signals indicating to road traffic that a train is approaching.
- Page 3 BLOCKsignalling www.blocksignalling.co.uk Power Supply The controller is designed for use with a 12V DC plug-top type power supply. The current consumption is 0.25A, and a power supply rated at 0.5A to 1A is recommended. If connected to auxiliary terminals on the back of a train controller the module may operate unpredictably and could be damaged.

- Page 5 BLOCKsignalling www.blocksignalling.co.uk Connecting the Infra-Red Sensor The infra-red sensor is used to detect the trains using light invisible to the human eye. An Infra-Red source and Infra-Red detector are moulded into a single 5mm x 6.5mm package that can be located below the track bed to reflect light off rolling stock.
- Page 6 BLOCKsignalling www.blocksignalling.co.uk Installation The Infra-Red sensor is normally installed below the track-bed. The detection range of the unit is up to approximately 25mm from the face of the package when normal sensitivity is set (for dark surfaces with low levels of reflectivity).
- Page 7 BLOCKsignalling www.blocksignalling.co.uk Sensitivity Setting The module is supplied with the sensitivity pre-set to suit most installations and should not need adjustment. In locations such as tunnels, or when the sensor is not mounted under the track bed, then it may be desirable to adjust the detection threshold.
- Page 8 BLOCKsignalling www.blocksignalling.co.uk Program Flow Diagram As mentioned above, there are a number of memory locations which can programmed with different values to change the operation of the module. Before starting, it is a good idea to write down the memory locations and the values you are going to set them to.

- Page 10 BLOCKsignalling www.blocksignalling.co.uk Led signal Sequences The diagram below shows the default UK sequence. By reprogramming the module, it is possible to change the timings of the flashing of the leds. This is not normally required unless you wish to model specific continental level crossings where the flashing rate is different, or the yellow aspect is not shown.
- Page 11 BLOCKsignalling www.blocksignalling.co.uk Setting 3 - Set Yellow Time Following a reset, the time that the yellow led is lit is set to 3 seconds. The duration can be changed here to between 1 and 255 seconds. See below for how to set this duration to zero so the yellow led is not shown (setting 19).
- Page 12 BLOCKsignalling www.blocksignalling.co.uk Setting 7 - Set Trigger Mode The default trigger mode is infra-red. It can be changed here to triggering by a switch or reed relay. Note, keeping the switch closed will keep the leds operating. For triggering by reed switch, increase setting 8 to allow the whole train to pass before the leds stop operating.
- Page 13 If this setting is set to 1, the red leds will flash. If it is set to 2, the red leds will be shown steady. This setting is used to adjust the light sequence for continental level crossings. ©blocksignalling.co.uk 2021 Steven Heaton Page 13 of 13...
