Hook-up Options
Not all connections are required, however additional features become available as the AutoSignal
senses more of the layout. At a minimum the AutoSignal should be connected to a block sensor,
either DCC current sensor or infra-red analogue sensor.
Servo extension leads are used to connect to the next and previous AutoSignals. These distribute
power along a row of adjacent blocks as well as communications between AutoSignal units.
Connecting the NEXT2 on the feather AutoSignal to the first diverging routes PREV connector will
activate the diverting route logic when 4ASP is selected.
Block
Block purpose / option
Block 1
Previous block
Block 2
Braking block. Connect an ABC unit via a relay to trigger
automatic braking when danger is set. Use consistent lengths so
all locos can be programmed to stop at the same distance from
the signal.
For analogue layouts the relay can be used to cut track power
immediately before a signal.
All braking blocks on the layout should be the same length. This
allows you to control the length of braking on your loco
decoder chip and have it stop the same distance in front of all
signals.
Block 3
The block detector sensor is connected to and monitoring the
block immediately after the braking block. If occupied the
AutoSignal will trigger danger and the braking circuit.
Block 4
Subsequent AutoSignals communicate to the AutoSignal on
their occupancy state. This triggers the various aspects as
defined by your selection jumpers.
Diverging route block
Connecting a point position sensor (
or micro switch
) triggers the
feather (
if fitted
). This will also activate the diverging route
signalling if AutoSignal is detected on “NEXT 2” connector.
