Azatrax TS5 Installation Manual

Installation Guide
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.
Kit 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
