Getting started
Thank you for purchasing a Logic Rail Technologies product! Please familiarize yourself with all the instructions prior to
installing this board. The Block Animator/2 (versions BA/2-SBCA, BA/2-SBCA-IR, and BA/2-SBCA-X) provides 3-aspect
(color or position) signaling for Tomar Semaphore motors, signals with bulbs and common anode LED position light signals.
The Block Animator/2 provides automatic operation of two 3-aspect block signals in a semi-prototypical way. Four sensors
(photocells or infrared emitters and detectors) are used for bidirectional train detection; two are used for the Eastbound signal
and two are used for the Westbound signal. The typical layout of the signals and sensors is illustrated below.

What is different from the original version of the Block Animator (BAD-SBCA, BAD-SBCA-IR)?
Signal outputs are turned on in sequence (Red Yellow Green), briefly, when power is first applied to the
board. This gives you a quick test of the signals to make sure all the connections are correct and the signals work!
The time delay between color changes is now adjustable from 1 to 127 seconds! You are no longer limited to
choosing between one of two delay times.
There are individual sensor status indicators on the circuit board. These not only help you when first setting up
the board but are also active when in "operating" mode.
The Flashing Yellow aspect has been added. When enabled the signal will transition from yellow to flashing
yellow before returning to green. This simulates an Approach Medium indication.
There is no need to swap chips on the board if you want to use a photocell, infrared between-the-rails, infrared
across-the-rails, and external detectors. However, you will need to decide which sensor type (photocell or
infrared), if any, you want at the time of purchase. Both sensor types are still available separately (#PCELL or
#BTR-IR4) if you want to change types!
The board is also offered without optical sensors (version BA/2-SBCA-X) for use with other brands of external
detectors.
The infrared detection method has been improved and no longer has strict limits on the incoming voltage.
the IR emitter wiring is different from the previous generation product!!! Please pay close attention to this.
We added another visual feature, Signal Fade, which fades individual aspects off and on when transitioning
between the indications (clear, stop, approach). This feature can be enabled or disabled on the board.
How does it work?
In the absence of any trains the two signals will be green. Now consider a train traveling eastbound. When sensor W1 is
activated signal WB will change from green to red and will remain red as the train continues eastbound and subsequently
activates sensor W2. When the train then activates sensor E2 signal EB will change from green to red. Once the train has
totally cleared sensors W1 and W2 signal WB will change from red back to green. As the train continues eastbound towards
sensor E1 signal EB will remain red. Once the train has passed over sensor E1 and totally clears both it and sensor E2 signal
EB will change to yellow; this mimics the behavior of the train entering the "next block." After a time delay (adjustable; see
page 7) signal EB will change to green. Signal operation for a westbound train is similar with signal EB changing from green
to red and back to green while signal WB changes from green to red to yellow and back to green.

Page 2: Approach Lighting
You should make all of the connections to the Block Animator/2 before applying power to it. You can mount the Block Animator/2 anywhere it is convenient underneath your layout using the four mounting holes provided. The holes will accept #4 screws; do not enlarge the holes as damage to the circuit board can result and your warranty will be voided! The Block Animator/2 board has a set of 10 configuration switches on it. - Page 3 3-light Bulb-based Signals (e.g. older NJ International) Wiring for 3-light bulb-based light signals is shown in Figure 2 using the Eastbound signal outputs; the connections are similar for the Westbound signal outputs. You will need the current limiting resistors if the voltage rating of the bulbs is lower than the input voltage to the Block Animator/2.

Clear position Stop position Approach position Center LED/bulb Common Current limiting resistors (see text) Figure 4 – Position light signal If your signal is an “absolute” type (that means it has two red LEDs/bulbs for the stop position while all others are yellow) then you will have to cut the wire jumper labeled JP8 for the Eastbound signal shown in Figure 5 on the Block Animator/2 board (jumper JP7 is for the Westbound signal). - Page 5 protrude enough from the underside of your layout then it will be necessary to extend the leads; soldering wires to them is the most common method; make sure you insulate any connections you make to the photocell leads so that they don't short out. Once you have wired the photocells to the Block Animator/2 and verified their operation you may wish to put a dab of white glue under the photocell to hold it in place;...
- Page 6 Using Between-the-rails Infrared The IR components should be mounted between the rails. Drill two 11/64” holes, through the ballast, roadbed, and sub-roadbed. These holes should be located one tie apart (Figure 9a) and drilled at a slight angle from vertical (see Figure 9b). The benefit of mounting them at an angle is increased detection reliability in smaller scales or irregular bottoms on rolling stock.

Signal color change delay The signal color change delay be adjusted between approximately 1 and 127 seconds. This delay time affects the transition from yellow to green. If flashing yellow is enabled then the yellow to flashing yellow and flashing yellow to green transitions will have the same delay. -
