Technical concept
Concentration on the essentials—with aspiration Siemens has developed a
new generation of traffic control technology. Here, the focus is perfection
of the commonplace and in connection with this the facilitation of
handling with the usual functionality. The result is the innovative traffic
controller, the Siemens Sitraffic smartX (sX).

1.1.

The modular hardware concept
For the new Sitraffic sX, an entirely new concept was developed for both
the hardware as well as the software and its tools. The idea of the modular
frame concept is that depending on requirements the basic frame can be
supplemented with additional add-on chassis.

12
Technical concept

Sitraffic sX
sX is a controller for traffic signaling devices. A motherboard with the
name CBU forms the core of the controller. On the motherboard there are
modules of the plug-in type, which are used for signal monitoring and the
detection of vehicles and pedestrians. There are LED switch modules
(LSHS) for 230 V LED plug-in signal head.
The version of the sX controller with 230V LED switches is called sX-H.
In order to construct a small controller, the following components are built
into the sX-H controller:

■ Motherboard CBU equipped with the following components:
□ Processor module OMC and processor module CBC for signal
control

□ Processor modules CHX and CMU for signal monitoring
□ Mode module CMD for the selection of the operating mode for
signal monitoring

■ Backplane CTB with spring terminals for connecting request keys and
confirmation devices to the CBU.

■ Power supply for CBU, CMD and OMC.
■ Backplane CBDH with multipin sockets for receiving an LED switch
LSHS and with spring terminals for the connection of the signal heads.

■ LED switch LSHS
■ Power supply APU for the logic of the LED switch
■ Power supply and monitoring CPDH for the LED signal heads of the
outdoor system
All modules are directly plugged into each other via plug connections. No
drop cables are needed in the basic version.
With this construction for a small controller the status of the 8 request keys
can be monitored; moreover, 8 confirmation devices and 8 signal groups
can be activated.

Technical concept

If two detector modules SLD4 are plugged into the two installation
locations intended for them X39 and X40 of the CBU, 8 additional
induction loops can be monitored. Alternatively, IO modules can be
inserted into these installation locations in order to be able to connection
additional request keys or confirmation signals. Contact of the CBU signals
to the outdoor system is established via spring terminals on the CTB
module.
The CBU installation locations X39 and X40 are connected to the
microprocessor module CBC on the CBU via a serial IO bus. All IO and
detector modules that were developed for the sX controller have an
interface for this IO bus. There are 2 identical IO busses, called IO1 and IO2.
The IO busses are RS422 busses for which all the bus participants are
switched in parallel. By attaching CLB backplanes to the CTB backplane, the
IO1 bus can be extended. Up to 8 CLB can be connected to the IO1 bus,
one after another. In the basic version, only the IO1 bus is present. An
optional IO2 bus allows another 8 CLB modules in another cabinet.
Therefore, a total of up to 16 CLB modules can be reached.
Each CLB has two installation locations for IO modules or detectors. For
connecting the outdoor system the necessary spring clips are available on
the CLB.
Also the LED switches have a serial RS 422 bus. It is called LS1 and LS2. Up
to 4 LED switches can be connected per LS bus. Only LS1 is available in the
basic version. The LS busses have a point-to-point connection.
Both the LS bus as well as the IO2 bus requires the interface expansion
module CEB. It is not included in the basic version.

Key data for cabinets
The main frame and the expansion frame can be installed in the similar
design cabinets manufactured by

■ Orlite (O) and
■ NKT (N)
from the factory and mounted to known standard bases. Depending on
whether only the main frame or multiple frames are required, cabinets are
available with different dimensions and with one or two doors.

A main frame can be installed in a 1O/N cabinet together with the standard
EVU component (for power supply). This has the following dimensions,
depending on the manufacturer

■ 806 x 380 x 1100 mm³ (W x D x H) for type 1N or
■ 785 x 380 x 1100 mm³ (W x D x H) for type 1O.

■ 1136 x 380 x 1100 mm³ (W x D x H) for type 2N or
■ 1115 x 380 x 1100 mm³ for type 2O.
A second main and expansion frame can be installed in an additional
cabinet. This combination results in a 3O/N cabinet (see Fig. 4) with the
dimensions

■ 1902 x 380 x 1100 mm (W x D x H) as type 3N or
■ 1900 x 380 x 1100 mm³ (W x D x H) as type 3O.

Fig. 4: 3O/N cabinet

Additionally, all variants feature a small operating door in one of the
cabinet doors behind which an operating and display unit is located.
Assembly tools
For all parts of the controller you must use Torx screws.
Suitable tools must be used.

Technical concept

Frame
For housing the components of the sX controller a broad principle add-on
chassis and a narrow add-on chassis were developed. This makes it possible
to install the main chassis in a 1N or 1O cabinet. This way up to 16 signal
groups can be handled in a 1O or 1N cabinet.
The following components are located in the main chassis:

■ Power distributor with fuses
■ Processors of the signal controller
■ Processors of the signal monitor
■ Vehicle detectors
■ IO modules for detecting request signals
■ IO modules for activating confirmation devices.
■

2 units of LED switch modules for 230-V LED modules

■ Power supply
Two LED switch modules LSHS can be mounted in the main chassis. Up to
16 signal groups are possible this way.
Two additional LED switch groups LSHS are housed in the add-on chassis.
Therefore, a total of 32 signal groups is possible.
Principle and secondary frames are screwed together. For installing them
into the device cabinet, the frames are mounted onto the rear wall of the
cabinet and screwed together with it.
The device cabinet is positioned on top of a slot. Through it all the ground
cables are guided up from below into the principle and secondary frame.
Spring terminals are provided for connecting the wires.
The IO modules and power supply add-ons have the same dimensions and
can be installed in the same IO module locations.
The add-on chassis is mounted onto the main chassis at the right. The
following parts are necessary for retrofitting:

■ Expansion unit or door /C10

L24730-E800-A3

Operating principle of the CBU

Fig. 12: Block diagram of the CBU

For the CBU (S24734-A870-A10) a control unit and a signal monitoring
unit of an intersection controller are built in onto one module. In the
figure, the area of the control unit is marked green (at the left) and that of
the signal monitoring unit red (at the right). Assemblies and modules that
are to be plugged into the CBU are highlighted white.
The control unit processes the signal plan and depending on the traffic
situation that is identified by the detectors generates switch requests for
the LED signal heads.

Siemens AG

V1.0

A001a / 2014-08-20

Sitraffic sX
Service manual controller technology

32
Components

The signal monitoring unit sets the LED signal heads in accordance with
the switch requests if—after having checked them—it has been
determined that no hazardous conditions result in the intersection.
The signal monitor can operate 230-V LED modules with the LED switches
of type LSHS.
If the signal monitor identifies that the outdoor system is functioning with
faults, it can switch off its operating power supply in order to prevent
hazardous signal monitoring conditions. Switching off takes place with a
relay on the CPDH. Both processor modules of the signal monitor can
switch off the operating power supply independent of each other.

The signal monitoring unit is redundantly structured for the two processor
modules CHX and CMU.

2.3.3.1.

CHX processor module
The processor of the CHX has a CMX real-time operating system and
processes the following tasks:

■ Receipt of a new signal pattern from the CBC via the Serial 1a
connection.

■ Examination based on the signal monitoring configuration for whether
the specifications of the control unit do not pose a risk to safety.

■ Setting the LED signal heads in the signal heads according to the
specification of the control unit. For this purpose, transmission of
control commands to the LED switches LSHS via the LS bus.

Components

■ Obtaining sensor information concerning the operating statuses of the
LED signal heads via the LS bus.

■ Transmission of sensor information via the Serial 3 connection to the
CMU module for parallel examination.

■ Examination of whether the outdoor system is functioning without
faults (LED module failure, fault currents, short circuits)

■ In the presence of hazardous conditions, switch off the outdoor system
via triac of the LED lamp switch or via relay of the CPDH.

■ Briefly generating faults that the CMU processor must identify by
activating the "monitor validation test" (MVT). If this is not the case,
switch off outdoor system via relay of the CPDH.

2.3.3.2.

CMU processor module
The processor of the CMU has a CMX real-time operating system and
processes the following tasks:

■ Parallel receipt of a new signal pattern from the CBC for the CHX via

module failure, fault currents, short circuits) on the basis the sensor
information in parallel with the CHX

■ In the presence of hazardous conditions, switch off the outdoor system
via relay of the CPDH.

■ Briefly generating faults that the CHX processor must identify by
activating the "monitor validation test" (MVT). If this is not the case,
switch off outdoor system via relay of the CPDH.

Components

Safety:
The two processors CHX and CMU constantly check each other for proper
functioning.
Via the relay of the CPDH they can switch off the operating power supply
for the signal heads independently of each other.
The "monitor validation test" (MVT) can be activated by each processor
module independently of the other. For this, both processors produce
cyclically artificial brief faults in order to test the other processor. The
outdoor system is switched off if the processor to be tested does not
identify a fault. If a processor notices that these faults do not occur
anymore, it switches off the outdoor system here too.

CPDH
For sX- H controller the CPDH (S24734-A884-A1) provides the 230 VAC for
the LSHS together with the associated monitors.
The CPDH has A relays, SSR relays with which the feed of the LED power
supply for the LSHSs of the processors of the signal monitoring system can
be switched independently of each other.
The CPDH is at the top right of the chassis. The first LED switch
Backplane(CDBH) is attached from below. The second CDBH is to be
attached to the first. For adding on a third and fourth CDBH there are
appropriate connectors available on the CPDH. All the control signals come
from the control module CBU via a ribbon connector from the left side. The
CPDH should be slid upward for repairs. For this, only the left lower screw
is to be undone.
Note
So that no components are damaged, the module is not to be touched at the
components. Removal is to be performed with a small screwdriver between
CPDH and CDBH in the X9-X14 area. To insert it, only the top edge of the
circuit board is to be pressed

LED switch LSHS
The serial high-voltage LED switch is called LSHS (S24734-A887-A1)
because it can activate and monitor 230 -V LED signal heads. The LSHS has
the following functions:

■ has an integrated B relay.
■ Offers redundant current and voltage monitoring.
■ operates 24 Triac outputs (230 V). (8 signal groups)
■ Connection of 230 -V LED signal heads from 5W to 18W
■ Up to 72- W per color output (corresponds to 4 LED heads at 18 W
each).

■ up to 36 W per Red 1 and Red 2 output.
■ Fuse of every triac output with 1 A
■ has an LED with which the signal head color can be red, yellow and
green for each switch. (LED 1 corresponds to CDBH output 1, LED 2
output 2, etc. up to LED 24).

■ Control/monitoring is supplied with 13V AC power potential-free.
■ is activated serially via a potential-free RS422 interface.
■ has an additional RS422 interface for activating additional LSHS in
serial mode.

Components

The LSHS module has 24 LED switches / with 32 outputs (Red1, Red2,
Yellow and Green). In each case three outputs for the colors red, yellow
and green are permanently assigned to a signal group.
For each LSHS module a CDBH backplane is required, on which the
terminals for the connection of the LED signal heads including the return
conductors are located. The CDBH is also used for carrying the control
signals and power supply to the LSHS module. For the sX controller two
CDBH/LSHSs can be installed in the main chassis and two CDBH/LSHSs in
the add-on chassis.
The CBU communicates with the LSHS modules 1-4 via the LS1 bus. This is
an RS422 bus with a transmission speed of approx. 600 kBit/s. The master
is the CHX processor on the CBU that asks for the status of the LSHS
modules (slaves) every network cycle. The LS1 bus is guided across the
CPDH and the backplane CDBH1 to the LED switches LSHS1. Here, the
information concerning LSHS1 is coupled and decoupled. The bus is guided
in amplified form to the next LSHS. (The LSHS modules are thus connected
in series at the LS bus.
The LED switches need a potential-free alternating current of 13 V AC for
their internal logic. For this an APU transformer is provided which feeds the
LED switches in the main chassis via CPDH and CDBH over two separate
windings.
A second APU transformer, which feeds the LED switches, is provided in the
add-on chassis. For structure see Fig. 2: Frame structure for sX-H and sXHx.
The fuses of the LSHS can only be accessed if the module is removed. Then
the slider plate can be slid back and fuse device is accessible. When
plugged in the slider plate is closed

CEW module
The CEW (S24734-A898-A1) is an electronic load module for the LSHS. This
can be if necessary in some cases, if external power supplies appear due to
capacitive linking of wire to wire in the outdoor system. The module affects
all outputs. This module is to be mounted on the rear side of the LSHS. For
this, the multipoint male connectors of the CEW are to be carefully plugged
into the LSHS and fastened with 3 screws (CEW component side to the
LSHS).
The CEW assembly set is as follows:

CDBH
The CDBH (S24734-A872-A1) is the backplane for the LSHS. It establishes
the connection from the LSHS module to the outdoor system.
The CDBH has the following functions:

■ Connection of controllers 1-4:

Red1, red2, red unmonitored, yellow,

green

■ Connection of controllers 5-8:

Red1, red2, yellow, green

■ 3 spring terminals are present for each color signal.
■ On the return conductor block (dark gray in the CDBH) 24 return
conductors can be connected. Up to 4 A per return conductor block.

■ For each CDBH a PE block with 16 terminals is to be installed onto the
top-hat rail. For CDBH 1 and CDBH 2 this takes place at the bottom left
in the main chassis. See, Fig. 2, no. 20. The PE block of CDBH 3 and
CDBH 4 is to be installed onto the right top-hat rail in the main chassis,
sees Fig. 2 no. 17.
The CDBH assembly set is as follows:
CDBH accessories /C10 L24734-A872-A10
For correct addressing of the LSHS modules, the address must be set on the
CDBH. For this there is an address field (X15) with ADDR0 to ADDR3 in the
top area. Here the appropriate address must be scratched. The signals to be
scratched are shown with an X.

CPA module
In the add-on chassis the CPA (S24734-A883-A1) is necessary for the
coupling of the 3rd or 7th CDBH including the corresponding LED switches.
The CPA is a small printed circuit board with three plug connectors which
provides the CDBH (and therefore the LED switches) with an interface
electrically and mechanically identical to the CPDH. For the power supply to
the LED switches in the add-on chassis the large APU transformer is
necessary.

2.12.1.

Installation for sX-H and sX-Hx
The CPA is used for 230-V devices with CDBH.
For this there is the following installation set:
For installation the following is necessary:

If only three LSHSs are used in the device, the 3rd LSHS with CPA can also
be installed on the installation location of the 4th LSHS, (the same applies
for the 7th LSxS with CPA). The existing connecting cables and the
mechanics are appropriate for both installations. In this case, additional
CLB installation locations are available on the left side.

sX-Hx device
For more than 32 controllers you will need a second cabinet. This way up
to 64 controllers are possible. This device is known as sX-Hx.
See the following overviews:

■ For the mechanical structure see Fig. 2
■ For 230 -V distribution see Fig. 9
Then the 2nd cabinet contains:

■ Main/add-on chassis
■ The 2nd CPDH
■ LSHS 5-8
■ APU transformer
■ Power distributor
■ Additional CLB places
■ The maximum total output of the system may not exceed 2760 W, so
that the same utility compartment can be used.
The modules CPDH/CDBH/LSHS/CLB are to be installed in the same places as
in the 1st cabinet. At the CTB location it can already be started with one
CLB.
Changes in the main chassis:

■ In the 1st main chassis the LED signal head fuse (F2) for the 2nd CPDH
is to be changed from single-pin 16AB to 2-pin 16AB.

■ For the 2nd LS bus (LSHS5-8) the CEB module is to be plugged into the
CBU.
For the serial connection of the 2nd CPDH the wire
C24700-K10-B181 is necessary.

CLB installation locations
The IO add-on locations available in the chassis are called CLB installation
locations. These can however be equipped with different functions, but not
all functions are attached at the IO bus.

Tab. 38: CLB installation locations

The I/O add-on in sX takes place from below at the module that can be
connected to the CTB. Here, the modules that are connected to the IO bus
(CLB and CIAB) are to be attached first. The modules are connected via the
IO bus to the CBU. For the modules CLB/CIAB there is a case that holds the
relevant backplanes and modules. Each backplane can hold 2 modules.
Installation of the modules not connected at the IO bus (power supply and
CUA) takes place toward the end of the installation locations.

2.15.

CLB
The size of a CLB installation location for the chassis of the sX device is
determined by the dimensions of the CLB (S24734-A879-A1).
In the first main chassis there are 3 CLB installation locations if counting
the two installation locations for detector and IO modules on the CBU. In

Components

the first add-on chassis there is room for a maximum of 7 CLB installation
locations.
Altogether there are thus 10 CLB installation locations.
Actually, a total of 18 modules can be operated in the main and add-on
chassis together. CLB installation locations not assigned CLBs/CIABs cannot
be assigned accessories such as auxiliary power supplies.
When planning it is to be noted that the CLB installation locations overlap
with the LED switch installation locations in the add-on chassis. Depending
upon number and affixing location of the LED switch backplane the
number of available CLB installation locations may be reduced.
For the second main chassis as well 3 CLB installation locations are
available because a CLB can already be installed there at the CTB location.
Modules up to a current consumption of 60 mA are supplied from the CBU
via the backplane.
Modules with higher current consumption must be supplied via the spring
terminals X6. When using the CIE/CIO the terminals have the designation
U+ and U-.
All modules that are to be plugged into a CLB are connected via IO bus 1 or
IO bus 2 to the master bus (processor CBC) on the CBU. Each module that is
connected to an IO bus needs a unique address. The setting of the DIP
switch on the CLB specifies the addresses of both plug-in locations. The left
plug-in location (X4) receives the even address and the right plug-on
location (X5) the odd address.
When making the setting, proceed as follows:
For both installation locations X39 and X40 on the CBU the addresses 14
and 15 are permanently set. The designation CLB1 is assigned to these two
installation locations. For the CLBs connected via the CTB the addresses are
set in sequentially increasing order. Tab. 39: Setting of the addresses with
IO bus 1 shows the setting of the addresses in the first main and add-on
chassis. The setting for the second main and add-on chassis is described in
Tab. 40: Setting of the addresses with IO bus 2. Because the modules in the
second chassis communicate via IO bus 2, the same physical addresses are
used as with the first chassis. For the use of IO bus 2 a CEB module is
necessary. See 0.

CLA module
The CLA (S24734-A878-A1) module serves to couple the I/O bus from
above to the CLB modules in the add-on chassis and to generate the
24V for the add-on chassis. The CLA module is to be attached at the top on
the CLB cage. When attaching, pressure can only be applied to the plastic
pin. Depending upon installation there may be 2 sets with accessories:
C10 CLA1 set L24730-E812-A3
(connection main chassis CLBx-X1 to the add-on chassis CLA_X1)

Components

The CLA produces +24V/750mA for the plugged-in modules. The 24V are
monitored and reported to the CBU. The current consumption amounts to
60mA for each SLD4, CIE; CIAC module. Unused current can be removed at
X4 (VOUT) and used internally. For a power supply for generation of 24V
DC, 21.5VAC is needed from the large APU transformer (V24068-Z5045A1). This is already available with a device with 3 or 4 LSHSs. Otherwise the
transformer set is necessary:

Tab. 15

Fig. 44: Loop activation

2.18.1.

UPLINK/DOWNLINK
Besides their IO bus (to the CBU) the SLD4 modules have an additional
communication interface which allows the SLD4 modules to communicate
with one another. This is accomplished without the help of an external
processor and is carried out automatically by the loop detector modules.
Via this detector connection the following functions are implemented:

■ Automatic frequency selection of the loops. This allows the master
SLD4 module to set the optimal frequency for all loops.

■ All SLD4 can be reset by pressing the reset button on the master
module and all LEDs turn on/off.

■ The PC SLD4 tool can communicate with all SLD4s (if the SLD4 master
is connected to the PC). This allows simultaneous collection of log files,
car data and car simulation for all detectors.
For this, it is important that the SLD4 modules can communicate with one
another. This requires that the UP and DNLINK signals are not disrupted. As
you can see in Fig. 45 the IO modules have to be plugged in consecutively
to each mounting slot (the detector link is a point-to-point connection and
not a bus). In this case the first module on the UPLINK bus takes the master
role; all other modules are slaves which can be controlled by the master.
It is not mandatory to insert only SLD4 modules consecutively; other
modules suited for the IO slot like CIE, CIO and DIB-E also connect the
respective signals correctly and loop through the bus.

Disruption UPLINK/ DOWNLINK
If a SLD4/CIE/CIO/DIB-E module is not set, UPLINK and DOWNLINK are
disrupted and the functionality is not available. Thus, another or several other
modules are set as master.

The same applies to the IO backplanes; here alternative backplanes like the
CIAB also can replace a CLB at any position without constraining the
functionality of the detector link. In the CIAB backplane the loopthrough of
the UPLINK and DOWNLINK signals is already available in the CIAB making
the CIAC redundant.

CLB slot change in mounting a power supply
If you mount a power supply in the CLB4 slot the CLB4 slot moves to the addon chassis and is there the top level module.

For each module the following inputs and outputs are possible:

■ 8 Inputs (labeled "INx").
■ 8 Outputs (labeled "OUTx")
The operating power supply is to be fed individually for each module at the
points labeled "+PED" and "- PED". Since usually 2 pedestrian buttons and 2
pedestrian conformations are there, there are 2 terminals available for

Video detectors
For the connection of video detectors, adapter cards with the designation
DIB-E and DIB-P are being prepared.

2.21.1.

DIB-E
The DIB-E (ZNX: DET-089-000151) is an interface module for the
connection of 6 video detectors (SIVICAM) to a Siemens intersection
controller. The DIB-E may be plugged into all SLD4 locations. In the sX
controller the data transmission is made via the serial I/O bus. Contrary to
the predecessor module DIB, the DIB-E has an interface for this serial IO bus
of the sX controller. Therefore the DIB cannot be used in an sX controller.
For function details on the SIVICAMs see "SIVICAM I-2 integrated video
detector user manual"
Note
A DIB cannot be plugged in to the sX controller because it has no IO bus

For required materials see Tab. 43.

2.21.1.1. Setting DIB-E address in the CLB
Here is to be proceeded exactly the same as with the CLB. See 2.15.

2.21.1.4. USB port
In order to be able to use the DIB-E with the service PC, the "TrafiCam® PC
Tool" must be installed on it.
With the PC tool up to 8 zones on the roadway can be defined for each
SIVICAM. For each zone the SIVICAM supplies information for whether it is
assigned a vehicle.
The information concerning the up-to-48 zones of the CBU is requested via
the serial IO bus. Thus the assignment of the zones to the hardware
outputs of the DIB-E is done away with, which is needed for the other
intersection controllers.
For settings see "TrafiCam - 4TI ETH or 1TI" USER GUIDE

2.21.1.5. Ethernet port
The DIB-E can alternatively be operated by the "TrafiCam® PC Tool" via the
Ethernet port. The same commands as with the USB port are available. In
order to be able to use the Ethernet port, the IP address of the DIB-E must
be set via the USB port.

2.21.1.8. Topologies of the networks to be connected to the SIVICAMs
The cameras can be connected with the connection terminals of the DIB-E
by star networks or linear networks. A combination of star networks and
linear networks is also possible.

Definition of the possible network topologies for SIVICAMs
Star network

Each SIVICAM is directly connected with
the DIB-E. Per SIVICAM a set of connection
terminals (RS485+, RS485, +24V, 0V and
PE) is needed.

Linear network

One SIVICAM is directly connected with
the DIB-E, all other SIVICAMs are
connected in parallel in a line. For all
attached SIVICAMs only one set of
connection terminals is needed.

Combined star network / linear
network

Individual SIVICAMs and lines are each
turned on at a set of connection terminals
of the DIB-E.

The two wires (0V and 24V) that lead to one camera must be twisted. The
shield of the ground cable is to be attached at the grounding connection
terminal of the camera and grounded in the intersection controller.
Per SIVICAM current consumption of 50mA at 24V is to be expected.
Because the auxiliary power supply can have up to 2.0A applied, up to 40
SIVICAMs can theoretically be operated.

Since an RS485 bus is concerned here, the signal wires of the camera must
be twisted. A and B wires may not be mixed up.

Note on connecting the RS485 bus
If the 24V operating power supply of the SIVICAM is supplied, a voltage of 2
to 3V can be measured between the A wire and B wire while idle. Here, the A
wire leads the positive voltage.
If a DIB-E is plugged in, this voltage also can be measured between the
terminals Vxa and Vxb, where Vxa is more positive than Vxb.
The A wire of the camera is connected to Vxa and the B wire to Vxb.

For the connection of AC confirmations/requests the CIAB backplane
(S24734-A897-A1) and the CIAC module (S24734-A896-A1) is needed. The
CIAB module has the format of a CLB module and is built in to the CLB
housing. Thus it can be installed in all CLB locations. The same housing as
for the CLB is used. Up to 2 CIAC modules can be plugged into the CIAB
backplane. For each CIAC module, 6 inputs and 6 outputs are available.
(There are thus 12 inputs and 12 outputs possible per CIAB).

CCU GPS internal
For determining the time a GPS receiver (CCU, V24734-Z894-A1) is
connectable. Thus world-wide receipt of time is possible. This is built in to
the exterior of the metal chassis in the cabinet. The CCU has a magnet on
the back side and is to be affixed to the non-perforated surface of the
chassis. The line is attached for the CBU_X31. After switching on it takes
approx. 2 minutes for the GPS time to be available.

CCUE GPS External
If at the place of assembly no GPS reception is possible (e.g. under bridges,
in buildings, under large trees) an external GPS receiver (CCUE, V24734Z895-A1) can be used. This is installed on a pole. In the sX controller a
driver module TEB must be installed for this.
The set for the installation in the sX controller is called:
CCUE prepared /C10

L24730-E810-A61

Upon delivery of the TEB all jumpers are in the position 2-3. For correct
operation of the TEB with the CCUE, only jumper X4 is to be changed to 1-2
(bottom). The TEB is to be installed at the bottom left onto the horizontal
top-hat rail in the main chassis.
The CCUE set for the external pole assembly including fasteners is called:
CCUE Set GPS ext. /C10

L24730-E810-A60

(The same housing and attachment are used as for the DCF receiver).

Note
The maximum permitted load of the RS100-24 is 48 W (2.0 A)

The replacement part number for the 24 V power supply is: V24069Z8043-A1.
Activation:
The 0V block in the device already in place is to be used and is not included
in the set.
For the plus voltage there are 2 terminals included in the set.
The auxiliary power supply is to be installed onto the mounting bracket.
Standard installation location is the lowest CLB location in the main
chassis.
See Fig. 5, no. 2
The mounting bracket can also be mounted on other CLB installation
locations on site. Then the line lengths are to be examined and if necessary
have the lines replaced by longer lines.
It must however always be the last installation location in the row because
no CLB/CIAB modules can be attached at the mounting bracket.
