Installation Guide Azatrax Model Railroad Track Signal Control - Control Point TS5

What it is: The TS5 operates up to four trackside signals,

each with one or two heads, at a control point on a dual

track mainline. A control point can be a single or dual

crossover, or the end of a shared passing siding. Track

configurations where the TS5 can be used are listed below.

Trains are sensed at the control point using IR (infrared

sensors that are independent of the room lighting. The TS5

does not require the rail to be cut into isolated blocks and

does not require resistor wheel sets on the train cars.

it contents:

★ Circuit board

★ Four IR (infrared light-emitting diodes (IR LEDs with

white and orange (or red leads

★ Four IR receivers with yellow and green (or blue leads

★ Plastic mounting tubes for protection of the sensor leads

and mounting support. Tubes are not essential for

detector operation and may be shortened or removed

entirely. Use caution to avoid damaging the leads.

★ 1,000 ohm resistors for interlocking functions (pg. 9

The TS5 includes four sensor pairs for detecting trains at

four locations. Some control point configurations need a

5th train detector, designated as D5 on the diagrams. An

Azatrax MRD1-NV circuit can be used as this 5th detector.

See page 6 for connection instructions.

TS5 circuits may be linked to up to five

other Azatrax TSx series signal circuits

so that successive block signals along

the track will be properly coordinated.

Most types of LED block signals may

be used. The TS5 automatically adjusts to the polarity of the

signals (common anode vs. common cathode .

All signals must be of the same polarity.

Limitations: The TS5 only senses trains as they pass the

detectors. Two TSx's, one at each end of a block, tell each

other when a train enters or leaves a block, so they can

deduce when the block is occupied or clear. Because the

TS5 does not actually sense the physical presence of a train

in the block, it can give false indications if part of a train

becomes uncoupled and is left behind in the block, or if a train

enters or leaves the block by some route other than the two ends

that are monitored by TSx circuits. To compensate for this, see

'Interlocking Functions' on pg. 9.

Turnouts, whether manually or electrically operated, must have an electrical contact (switch) that indicates the

turnout's position The contact must be 'open' ('off' when the turnout is in the Normal (main route position, and 'closed'

('on' when the turnout is Reversed (branch or diverging route . Turnout connections are shown on page 4.

Some electric switch machines such as Tortoise, Cobalt and Kemtron have built-in contacts. If your switch machines do not

Crossover Turnouts -- The two turnouts of a crossover track should be

mechanically or electrically linked so that they always work together.

The TS5 assumes that both turnouts will be lined for the main (Normal

route, or that both will be lined for the crossover (Reverse route.

Crossover labels, T1 & T2 -- Crossover T1 takes

trains from track 1 to track 4. Crossover T2 takes

trains from track 2 to track 3.

Select a track configuration:

Find the track configuration that matches your control point and set the 'track config' jumper (small rectangular connector

block, or 'shunt' on the TS5 as shown.

On the following diagrams, note carefully the track, sensor and signal numbers, and how they are arranged.

opposite end of the siding.

Turnout T3 indication -- Normal position is toward Track 1. Reverse position is toward track 2.

Turnout connections are required:

♦ Switch machine contacts or latching relays must be connected to the TS5

turnout inputs so the TS5 can be aware of turnouts that are set for a diverging

route (Reverse .

♦ For crossovers T1 & T2, only one contact is needed for each crossover, it may

be linked to either turnout on that crossover. The contact must close (be 'on'

when the crossover turnouts are lined for the crossover (Reverse , and must open

(be 'off' when the turnouts are lined for the main line (Normal .

♦ For turnouts T1 & T2 (shared passing siding and turnout T3 or T4, one contact

is needed for each turnout. The contact must close (be 'on' when the turnout is

lined for the crossover (Reverse , and must open (be 'off' when the turnout is

lined for the main line (Normal .

♦ The four turnout/crossover inputs are not all used at the same time. Only connect the inputs called for in your track

configuration diagram. Unused inputs are left open (no connection .

Connect power to the TS5: Connect an accessory power supply of 9 to 16 volts

AC or DC to terminals P1 & P2. The yellow and red LEDs will briefly flash to

show that power is on and the circuit is working.

Turn power off before changing any connections.

Install the sensors: Each sensor pair (one IR LED and one IR receiver may be installed in one of two different ways -

'Across-Track' or 'Reflective.'

Place sensor pair D1 just ahead of the turnout point rails on Track 1. Place sensor pair D2 on Track 2, sensor pair D3 on

Track 3, and sensor pair D4 on Track 4.

Across-Track sensing: The IR LED is positioned horizontally on one side of the track, and the IR

receiver is placed on the opposite side. A train is detected when it blocks the light path between the LED

and receiver. The distance between the IR LED and its receiver can be up to 18 in. (45cm . Placing the

sensors at an angle across the track avoids possible detector flickering

caused by the gaps between cars.

Tip #1 - If mounting the sensors vertically as shown here, slide the plastic

tubes away from the sensor then carefully bend the leads to a right angle.

The leads are somewhat brittle, bending them more than two or three times may cause a break.

Tip #2 - Locate the IR receiver so it faces away from bright lights or sunny windows. Use scenery or

structures to conceal the sensors and shade them from bright light.

Reflective sensing: Trains are detected when light from the IR LED is

reflected off a train and sensed by the IR receiver. Typically the sensors

are mounted in two 3/16-inch (4.8mm holes drilled in the roadbed as

shown here. Vertical installation works for S and larger scales as long

as there is no structure above the track such as a bridge.

Angling the IR LED and its receiver toward each other is best for N and HO scale where the trains are close to the rail head,

and in places where an object above the track might otherwise cause false detections. Angle the IR LED and receiver so

their centerlines intersect at the height of the bottom of your rolling stock.

Tip #3 - You can ballast your track after sensors are installed. Cover each sensor with a bit of transparent tape. Apply

ballast. When the glue has dried use a dental pick or similar tool to remove ballast from the sensors. An opening of

just 1 or 2 mm is required.

Connecting wires to the terminal blocks: The TS5 has 'spring cage' quick-connect terminal blocks.

◆ Strip 3/8 inch (1 cm of insulation off the end of the wire.

◆ Use a small screwdriver to push down (push, do not turn the terminal's button. Push firmly.

◆ While the button is pushed in, hold the wire at a 45 degree angle to the terminal block and push it in.

About 3/8 inch of wire should go into the terminal block.

◆ Release the button. Tug on the wire to make sure it is secure.

When two wires are connected to the same terminal, twist the bare ends of the wires together.

Connect D1 sensor pair: With power off, connect the red or orange wire from the IR LED to terminal 1K. Connect the

blue or green wire from the IR receiver to terminal 1F. Now, how you connect the white and yellow wires to the TS5 will

determine whether the D1 detector will operate in 'Across-Track' or 'Reflective' mode.

Test D1 before connecting the next sensor pair. Turn on power. When all sensors are clear of objects, all detector LEDs on

the TS5 circuit board should be off. Place a rail car at sensor D1. Detector LED 1 should light. Remove the railcar and

verify that LED 1 turns off. If not, see Sensor Troubleshooting below.

Connect D2 sensor pair: With power off, connect the red or orange wire from the IR LED to terminal 2K. Connect the

blue or green wire from the IR receiver to terminal 2F. As with sensor D1, how you connect the white and yellow wires will

determine whether the D2 detector will operate in 'Across-Track' or 'Reflective' mode.

When both sensor pairs are connected, there will be two yellow (or white wires in 'X' and two white (or yellow wires in 'R.'

Where two wires share the same terminal, twist the bare wire ends together to ensure a reliable connection.

Test D2 before connecting the next sensor pair. Turn on power. When all sensors are clear of objects, all detector LEDs on

the TS5 circuit board should be off. Place a rail car at sensor D2. Detector LED 2 should light. Remove the railcar and

verify that LED 2 turns off. If not, see Sensor Troubleshooting below.

➽ Pairing is important! The IR LED that is connected to 1K must be paired on the layout with the IR receiver that is

connected to 1F. The IR LED that is connected to 2K must be paired with the IR receiver that is connected to 2F.

Additional wire may be spliced to the sensor leads if needed. Use similar twisted pair wire for total length up to 26 ft (8m .

Install and test detectors D3 and D4 in the same manner as D1 and D2 above. The D3 sensors connect to terminals 3K, 3F,

X and R. The D4 sensors connect to terminals 4K, 4F, X and R.

Detector D5, if needed, is an external detector circuit such as an

Azatrax MRD1-NV. Install the infrared sensor and connect it to the

MRD1-NV according to the MRD1-NV instructions. Then connect

the MRD1-NV to the TS5 as shown here. The same power supply

used for the TS5 may also be used for the MRD1-NV.

Sensor Troubleshooting:

With trains clear of all sensors, the detector LEDs on the TS5 should be off. If any LED is on, correct the false sensing

condition.

To fix false sensing for Across-Track mode:

1. Verify that the sensor pair is wired correctly.

2. Make sure the IR LED and receiver are pointed at each other, and nothing is between them.

3. Shade the IR receiver from bright lights, and point it away from windows or other strong light sources.

4. Change the nearby room light from incandescent to a fluorescent or LED bulb if possible.

To fix false sensing for Reflective mode:

1. Verify that the sensor pair is wired correctly.

2. Pull the IR LED and its receiver a bit deeper into the roadbed.

3. Infrared light may be 'leaking' through the roadbed material from the IR LED to the IR receiver. Push a metal shim, such

as the tip of a hobby knife blade, vertically into the roadbed between the IR LED and receiver.

4. Is there an object above the sensor, such as a bridge, or an upper layout level? Mount the IR LED and its receiver at a

shallower angle, or paint the object flat black. Or use across-the-track sensing.

If a detector LED does not light when a train is present at the corresponding detector, correct the false clear condition.

To fix a false clear indication for Across-Track mode:

1. Verify that the sensor pair is wired correctly.

2. Adjust the sensor height so the train is fully blocking the light path from the IR LED to the IR receiver.

1. Verify that the sensor pair is wired correctly.

2. Adjust the sensors higher or lower in the roadbed.

3. A bright light source above and to the side of the track may be saturating the IR receiver. Try pulling it deeper into the

roadbed or shade it with scenery or a structure. Change the nearby light from incandescent to a fluorescent or LED bulb.

Test with several types of rolling stock and adjust the sensors as needed.

Signal configuration jumpers

Two configuration jumpers (small rectangular connector blocks, or 'shunts' are supplied with the

TS5 for adjusting signal characteristics. Three pairs of pins can accept these jumpers. To enable a

configuration feature, place a jumper across both of the pins. To disable a feature, remove the

jumper or park it on one pin.

Yellow adjust jumpers are only for searchlight signals with one bi-color (red/green LED. To

produce a yellow color, the red and green internal LED chips are illuminated together. The quality

of the yellow light is variable, depending on the viewing angle, ambient light and the LED itself.

+G: If the 'yellow' color looks too reddish, place a jumper across the two +G pins to increase the green intensity.

+R: If the 'yellow' color looks too greenish, place a jumper across the two +R pins to increase the red intensity.

A 'middle' yellow is produced when both jumpers are off.

4A: A jumper across this pair of pins enables four aspect signaling (clear / advance approach / approach / stop .

Removing the 4a jumper selects three aspect signaling (clear / approach / stop .

Signal Connections

The following types of signals may be used with the TS5. Single-head signals connect to "upper" terminals.

Connect your signals to the TS3

according to the diagram that

matches the signals.

Searchlights with four wires are

the same as 3-LED signals.

For PRR signals, add the wire

from lower 'Y' to 'Rtn' as shown.

With very fine signal wires, it is best to attach larger wires (AWG #26 or #24, such as wire

from phone or LAN cables to the fine signal leads, then insert the larger wire in the terminal block.

Sensors must be working correctly before continuing the installation.

Only change connections when power is off.

Connect any signal "common" to any "Rtn" terminal.

Note that resistors are not required because resistors are built in to the TS5 circuit board.

If your signals are pre-assembled with resistors, first connect the signals with their resistors. If the signal LEDs are too dim,

remove the resistors and re-connect the signals.

If an individual color is too bright, a resistor may be wired in series with that LED's wire. Use up to a 1000 ohm resistor.

Increasing the resistance value decreases the brightness.

When power is turned on, the TS5 does not know if a block is occupied or not, because a train may have been added or

removed from the track while power was off. The signals will show 'approach' (yellow (or red for 2-aspect signals .

Visually check the track and proceed with caution! Normal indications begin once the first train passes the IR sensors.

When the TS5 is linked to other Azatrax TSx circuits, the TSx circuits tell each other when a train enters or leaves the

block between them. When a train enters a block, the block is 'occupied' until a train exits the block. The block is then

considered to be 'clear.'

Connect a 'Link' terminal of one TSx

to a 'Link' terminal of the TSx at the

opposite end of the block. Connect

'C' of one TSx to 'C' on the other

TSx. Use twisted pair wire such as

found in telephone or ethernet (LAN

cable, AWG #26 or #24. To avoid

interference from high power or high

frequency currents, keep this wire

away from track power wires.

One example of linked signal circuits:

If a TS5 link is not connected to another Azatrax TSx circuit down the track, that track operates in a timed mode. The

track beyond the signal becomes a 'virtual' block. When a train passes the signal and enters the virtual block, the signal

shows a 'stop' aspect (red to indicate the virtual block is occupied. After several seconds the signal changes to 'approach.'

After another delay the signal changes to 'clear' (green . The delay time is not adjustable.

Interlocking functions

To force a block to 'occupied' status even when no train is

in the block, connect a 1,000 ohm (1k resistor between the

'Link' terminal (L1 - L5 and a 'C' terminal. This can be

connected via a dispatcher's switch, or a switch linked to a

drawbridge, a switch machine, etc.

In the example at right, the dashed line is a track block

between TS5 #1 at the west end, and TS5 #2 at the east end.

The red arrows point to the signals at the west and east

entrances to the block. These two signals will show 'stop' if

switch Sw1 is closed ('on' , connecting the 1k resistor across

the Link wire and 'C'.

To manually clear an 'occupied' block, momentarily connect the 'Link' terminal (L1 - L5 directly to a 'C' terminal. This

may need to be done after a train leaves the block through a turnout onto a siding or branch line, or if it is removed from the

track by hand.

In the example above, when Sw2 is momentarily closed, shorting the Link wire to 'C', the two signals indicated by the red

arrows will change to 'clear.'

Signal override with Stop inputs

Using Stop inputs S1 - S5, any of the five signals

controlled by a TS5 can be forced to show 'stop', or

restricted to 'approach' or 'diverging approach'

indication. This can be useful when the control

point has turnouts to uncontrolled sidings.

To force Signal 1 to show 'stop', connect terminal

'S1' to any 'C' terminal. To limit Signal 1 to

'approach' for a single-head signal, or 'diverging

approach' for a dual-head signal, connect terminal

'S1' to a 1,000 ohm (1k resistor, and connect the

other end of the resistor to any 'C' terminal.

Use terminal S2 to control Signal 2 in a similar fashion. Use 'S3' for Signal 3, 'S4' for Signal 4, and 'S5' for Signal 5.

In this example, a turnout to an uncontrolled siding is between signals 2 and 4. An electrical contact is linked to the turnout

points. This contact closes ('on' when the turnout is lined for the siding. This connects terminal 'S2' to 'C', causing Signal 2

to show 'stop.' This also connects 'S4' via a 1k resistor to 'C', causing Signal 4 to show 'diverging approach.'

Signal indications and single vs. dual head signals

A single head signal shows track conditions ahead on a single track without turnouts. A 'stop' indication (red means

the track block immediately beyond the signal has a train in it, or an open drawbridge or other hazard. An 'approach'

indication (yellow means it is safe to enter the block, but the following signal is at 'stop,' so slow down and be

prepared to stop at the next signal. If 4-aspect signaling is in use (see the signal config jumpers on page 7 an

'advance approach' indication (flashing yellow means it is safe to enter the block, but the next signal is at

'approach,' so reduce speed accordingly. A 'clear' indication (green means the track ahead is clear and trains may

run at up to the posted speed limit.

Dual-head signals are located where there is an upcoming turnout. A train

may continue on the main line or take a diverging route depending on how

the turnout is lined (Normal vs. Reverse . If the lower head indicates 'stop,'

then the turnout is in the Normal position and the upper head indicates the

condition of the main track ahead. If the upper head indicates 'stop,' then

the turnout is in the Reverse position and the lower head indicates the

to be connected to the lower head. Both practices are used by prototype railroads.

Signal test button

Check signal operation with the 'test' button. The button is very small, it is best to use the eraser end of a pencil or other

non-conductive tool to press it.

1. Hold the test button down for 2 seconds until the yellow on-board LED 1 starts flashing. Release the button. Signal 1

upper head should show 'clear,' all others signals will be dark.

2. Press and release the button. If the '4a' config jumper is in place the signal will change to

'advance approach,' otherwise it will show 'approach.'

3. Repeat pressing the button for 'approach' and 'stop.'

4. Press again. If the lower head of signal 1 is connected, the above steps will repeat for the

lower head.

5. Press again and the yellow on-board LED 2 will flash. Repeat the above steps for Signal 2.

6. Press again and the red on-board LED 3 will flash. Repeat the above steps for Signal 3.

7. Press again and the red on-board LED 4 will flash. Repeat the above steps for Signal 4.

8. Press again and the yellow LED 1 and red LED 4 will flash. Repeat the above steps for

Signal 5.

When the on-board LEDs stop flashing, the TS5 is back to normal operation.

Use a non-conductive tool

to press the test button.
