Azatrax Model Railroad Track Signal Control - Diamond Crossing
TS5
What it is:
The TS5 operates up to five trackside signals,
each with one or two heads, at a
diamond crossing
of two
single rail lines. One or two optional transfer tracks and one
signaled siding or branch line can also be included in the
signal system. Track configurations are listed below.
This is a special mode of operation of the TS5 controller,
enabled when configuration jumpers
(connector blocks, or "shunts") are
placed on the pair of "X" pins and on the
pair of "Z" pins. Other TS5 operating
modes can be selected by changing these
jumper settings. See the standard TS5 instructions, which
can be accessed at
www.azatrax.com/cp
Trains are sensed by 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.
If a signaled branch line or siding is included in
the signaling, a 5th train detector is needed.
It is designated
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 tracks 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

Signals with incandescent bulbs need solid
state relays such as Azatrax model SSR6
between the TS5 and the signals.
