Light Functions; Switch Functions - Train-Tech Sensor Signals Instructions Manual

• Using Mimic Switches with Sensor Signals
•
Sensor signals may be used on their own but Train-Tech Mimic Switches and Mimic Lights are a
great way of both controlling and monitoring your signals and trains on a control panel.
Mimic switches can override a Sensor Signal to show stop/caution or switch on a route indicator and
they come supplied with 2 plug-in LEDs to show the red, green or yellow state of the signal they are
connected to, as well as train presence and occupancy of the following block. It is easy to mount
using a single mounting hole and easy to connect having just a single wire to the signal and 2 wires
to the same DC or DCC supply that you are supplying the signals from.
Mimic Switches come in two versions fitted with either a 3 way toggle switch or push button and
there is also a Mimic Light version which has just the indicator lights and no control. Mimic switches
can also be used to control and monitor other Layout Link compatible products such as points and
level crossings - full instructions supplied with each Mimic product or see Train-Tech.com
Mimic Switch Wiring and Functions

LIGHT FUNCTIONS:

LED A mimics the signal status:
Red, Yellow or Green
Pulsing red if on Manual override
LED B Train passing & occupancy:
Pulses as train goes past signal
Constant while train is in following block
LED C (optional - no LED socket fitted)
Mimics signal's route indicator
(if a feather or theatre version)
LED D (optional - no LED socket fitted)
Lights as train passes the sensor
LED E (optional - no LED socket fitted)
Mimics the 2nd yellow (if fitted on signal)
• Using DCC to control a Sensor Signal
In addition to using a mimic switch you can use DCC to override a signal and/or control a route
indicator. Train-Tech products use a unique system called One-Touch DCC to easily set up any
DCC accessory - note you must set controller to DCC Accessory control mode, not loco mode.

To Setup a Sensor Signal for DCC manual override control
To setup your signal for DCC manual override, use a short link of insulated wire
to briefly touch together the two hidden 'Learn' contacts (see picture) until the
signal lights flash, then send a Direction ▹ / " or a 1 / 2 (depending on the make
of your controller) on the accessory address you want to use to manually
override your Sensor Signal. The signal will stop flashing and your Automatic
signal can now be overridden at any time using the command and address you
chose - change it between override / automatic using ▹ / " or 1 / 2 command on
your address. Other Sensor Signals linked to this signal will react correctly too,
so for example a distant will display yellow when the following signal is red. Make
sure you choose an address which is not used by anything else on your layout!
To set up DCC control of a Feather or Theatre indicator on a Sensor Signal
To setup a signal with a Route Indicator, use a short link of insulated wire to
briefly touch together the two hidden 'Learn' contacts (see picture) until the signal
lights flash, then touch them again and the Route indicator should flash.
Send a Direction ▹ / " or a 1 / 2 (depending on your controller) on the
accessory address you want to use to use to turn the Route on. The Route will
stop flashing and will now light using the command and address you chose. You
can use the same address as a DCC controlled point so that it changes with the
point - note that the route indicator always lights with the same ▹ / " or 1 / 2 you
used to set up, so use the same as the point to make them work together.
