BLOCKSignalling Level Crossing Module Automated Barriers & Sound LCS6B
Fully Flexible Controller with Sound and Servo Motors for Barriers or Gates
- Automatically detects traction current drawn by scale model trains approaching the level crossing
- Suitable for single or multiple tracks on DC or DCC layouts
- Operates attached yellow and red leds on level crossing signs (not included)
- Plays one selected sound from a choice of 18 pre-recorded levels crossing sounds from around the world
- Operates two servos (included) for connection to crossing barriers or gates across the road
- Once train has cleared the track section, the barriers return to their start positions automatically
- Built-in programs to cover most UK crossing styles
- Fully programmable to suit the modeller's requirements to replicate crossings from around the world
When triggered by infra-red sensors plays a digitally recorded sound, operates the crossing lights, and operates attached barriers or gates. The LCS6B has been designed to detect model trains on single or multiple tracks at a level crossing by monitoring the track current.
The module has a choice of 18 pre-recorded 10 second sound samples representative of the UK Yodalarm, ringing bells, US wig-wags, US slow bells, Continental gongs, Asian Electronic Sounders, etc.
Each servo operates automatically between their start and stop positions, which have been pre-programmed for ease of use. These can be mounted beneath the baseboard with scales like OO and N gauge, or can be mounted above the baseboard when operating barriers on larger scales.
Servo Motors
Servo motors consist of a small dc motor and gearbox combination, designed to drive an externally mounted arm (horn) through a limited range of angles. The motor operates at high speed, and the gearbox reduces the speed to a more appropriate level and so increases the torque significantly. An in-built control circuit varies the motor direction and speed to allow the output shaft to turn to the desired position.
Servos are compact and easy to mount. The barrier or gate can be directly attached to the servo by fixing a wire into the centre of the output shaft with epoxy, or a variety of horns can be mounted on to the output shaft and then extended with thin modelling wire to connect to gates, barriers and signals, etc.
The Level Crossing Controller LCS6 drives two servos from their parked position (START position) to their destination (STOP position). For ease of use, the start position and stop positions are pre-programmed to cover an arc of approximately 90 degrees (for use with barriers or gates). This can be varied if required.
Default Operation
When the level crossing module is triggered by a train, it commences playing a 10 second sound clip, and operating the standard lights sequence (note, it is not necessary to connect lights, and this part of the program can be bypassed when barriers are being used without lights).
Once the module enters the phase of the flashing reds, it commences the movement of servo 1. Depending on the programme selected, servo 2 may move at the same time as servo 1, part way through the movement of servo 1, or after servo 1 has fully completed its movement.
This allows the modelling of the following types of level crossings:
1. level crossings where there are pairs of gates, which are operated sequentially, and would collide if operated together
2. level crossings where both barriers fall at the same time
3. level crossings where the second barrier commences lowering part way through the lowering of the first barrier
4. level crossings when the second barrier falls only after the first barrier is completely lowered
When the train has cleared the crossing, the two servos either operated simultaneously back to their park position (for barriers) or operate sequentially (for gates).
The default range of operation of the servos as supplied is approximately 90 degrees.
Power Supply
The module operates from AC, DC or DCC (track bus) supplies.
You can use a DC power supply between 12V and 25V DC, or any AC power supply between 12V and 16V AC.
If using DCC, the feed can be between 12V and 25V, which covers all normal DCC layouts.
Where a choice is a available, a 12V DC supply is recommended.
