WORKING MAY BE CONSIDERED.
Safety of Maintenance Personnel
In the interests of health and safety, when using or servicing this equipment the following
instructions must be noted and adhered to:
•Only skilled or instructed personnel with relevant technical knowledge and experience,
who are also familiar with the safety procedures required when dealing with modern
electrical/electronic equipment are to be allowed to use and/or work on the equipment.
All work shall be performed in accordance with the Electricity at Work Regulations
1989 or the relevant local, state and government regulations.
•Such personnel must take heed of all relevant notes, cautions and warnings in this
Handbook and any other Document or Handbook associated with the equipment
including, but not restricted to, the following:
•The equipment must be correctly connected to the specified incoming power supply.
•The equipment must be disconnected / isolated from the incoming power supply
before removing any protective covers or working on any part from which the
protective covers have been removed.
•Any power tools must be regularly inspected and tested.
•Any ladders used must be inspected before use to ensure they are sound and not
damaged.
•When using a ladder, before climbing it, ensure that it is erected properly and is not
liable to collapse or move. If using a ladder near a carriageway, ensure that the area is
properly coned and signed.
•Any personnel working on site must wear the appropriate protective clothing, e.g.
reflective vests, etc.
In the event of any person working elsewhere on the junction, it is recommended that the
Mains Supply to the controller be switched off and the master switch locked in the ‘off’
position.
If you are not certain that the entire system is ELV, you must switch off the
Mains Supply to the controller and lock the Master Switch in the ‘off’ position.
If the controller uses an Expansion Cabinet, and in the exceptional
circumstances that the expansion cabinet also needs a mains supply (to be
avoided wherever possible), then the supply to the expansion cabinet must
also be switched off and the master switch in the expansion cabinet locked in
the off position.
To ensure and guarantee isolation the double pole master switch should be opened.
When re-commissioning signals, the following sequence is recommended to ensure that the
correct signal startup sequence is followed:

•Switch OFF the controller at the main switch
•Switch ON the lamps at the Manual Panel on/off switch
•Switch ON the controller at the main switch
More specific safety information is given in the text of the handbook, where it relates to
particular activities or situations.
For Hardware Fail Flash (HFF) Controllers Only (non UK only):
If the controller needs to be changed to HFF after being installed (non UK only) the following
procedure must be followed:
•Ensure that the power to the controller is switched off
•Move the "Flash" switch (S3) on the CPU Card to its non-HFF position
•Ensure that the link on the HPU is in the HFF position
•Run the Controller Self-Test and confirm that it indicates that the controller hardware is
set up for HFF. Note that the signals will not flash when the controller is powered
because the switch on the CPU Card is in the non-HFF position
•Switch off the power to the controller
•Move the switch on the CPU Card to its HFF position
•Switch on the power to the controller and ensure that the correct traffic signals flash as
the controller starts
There are various RJ45 connectors used to connect to peripheral cards within
the ST950 family of controllers. Most are not Ethernet ports and should not be
connected to other equipment, including PCs.

To isolate the equipment, the Master Switch must be in the “Off” position.
Removal of the Electricity Board Fuse or Switching the Controller switch or the Manual Panel
Signals On/Off switch to “Off” does not guarantee isolation of the equipment.
Controllers require specific configuration to enable them to function correctly when installed.
The configuration process is a complex activity and should only be carried out by persons
who are adequately trained, have a full understanding of the needs of the county or region
were the controller is to be used and are experienced in the tasks to be undertaken.
Do not connect any device that has not been specifically designed or tested for
compatibility with the ST950ELV system. If in doubt, contact Siemens Poole for
further information.
ST950ELV compatible equipment such as Helios ELV traffic signals, near-side
pedestrian signals and ELV LED regulatory signs are all clearly marked “ELV”. If
equipment is not marked “ELV” then additional care should be taken to ensure
that it is suitable for use in an ELV system.
Safety of Road Users
It is important that all personnel are aware of the dangers to road users that could arise
during repair and maintenance of traffic control equipment.
Ensure that the junction area is coned and signed as necessary to warn motorists and
pedestrians of any dangers and to help protect the personnel working on the site.
Whilst repairing signals which are in an "all-out" condition, care must be taken to ensure that
no spurious signals are lit during testing which could mislead drivers or pedestrians.
Particular care is required where pedestrian audible devices are installed, to ensure that no
false indications are given during, for example, cable testing. Personnel should also ensure
the safety of pedestrians, especially children, who may come into contact with parts of the
controller or signal poles.
Safety Warning - Lithium Battery
This equipment may contain a Lithium coin cell (battery) if the optional RTC battery backup
kit is installed.
Do not short circuit, recharge, puncture, take apart, incinerate, crush, immerse, force
discharge, ingest or expose to temperatures above the declared operating temperature
range of the product, otherwise there is a risk of fire or explosion.
Batteries should be handled and stored carefully to avoid short circuits. Do not store in
disorderly fashion, or allow metal objects to be mixed with stored batteries. Keep batteries
between -30°C and 35°C for prolonged storage.
The battery is a sealed unit which is not hazardous when used according to these
recommendations. Do not breathe vapours or touch any internal material with bare hands
should the cell become damaged in any way.

Battery disposal method should be in accordance with local, state and government
regulations. In many countries, batteries should not be disposed of into ordinary household
waste. They must be recycled properly to protect the environment and to cut down on the
waste of precious resources.
Important ELV Considerations
To provide the most reliable operation, Siemens ELV controllers use a DC
(unsmoothed) lamp supply, which in common with DC powered
telecommunication equipment, is negative with respect to earth so as to avoid
electrochemical corrosion effects.
To maintain all street voltages within ELV limits, equipment outside the cabinet
must be supplied with voltages within the band -48V RMS with respect to earth.
Voltages positive with respect to ground / earth will result in overall voltages
within the system being in excess of the ELV limit as defined by BS7671.
Care should be taken to ensure that no LV (Mains Voltage) equipment is
installed within the ELV street furniture as this will result in risks to personnel
and risk of catastrophic failure of ELV equipment should such voltages be
applied to the ELV equipment by accident.
The Siemens ELV controller has been designed and proven to meet the
following requirements for Protective Extra Low Voltage (PELV) and the
operation of a signal compliance monitoring system with ELV voltages:
1) The Siemens ELV system is PELV and the earth is connected all the way
through, as allowed for in BS7671 414.4.1. The source is a safety isolating
transformer to BS EN 61558-2-6 as allowed in 414.3 (i). Protective Isolation
within the controller cabinet is achieved between the PELV circuits and those
higher than band I by ALL conductors having insulation rated for the highest
voltage 250V, as mandated for in 414.4.2 (iii), and where the parts of the
circuits are not wires / conductors, then physical isolation as allowed for in
414.4.2 (v) may be used.
Any third party ELV sources installed in this system should follow the same
guidance, re-isolation and insulation and should adopt the same polarity and
voltage range to avoid voltages in excess of ELV band 1 being present in the
signalling / street furniture part of the system.
2) Terminations are IP2X (British standard finger proof i.e. not accessible to
solid items of 12.5mm or greater).
Any third parties making alterations to such equipment / PELV installations must consider
the electrical requirements for PELV and the above in what they do, and should only attempt
such alterations if they are competent to do so.
The controller monitors its signal outputs for both positive and negative voltages with respect
to earth for its conflict system. In order to ensure the ELV voltage band is maintained,

positive voltages with respect to earth are clamped by the controller. Should a positive
voltage be applied to the signal outputs, the controller will consume current to maintain a
maximum positive voltage of approximately 0.8 volts at the controller terminals.
Should a source with a large current sourcing capability be applied, catastrophic damage
may result. The extent and results of such damage cannot be predicted or guaranteed.

The essential differences between the ST900ELV and the new ST950ELV family of
controllers are:
•New CPU Card providing additional functionality and interfaces
•Improved user interfaces including web pages
•I/O card firmware can be updated in-situ.
•Support for existing ST900 equipment such as Gemini and Gemini2
•Integral MOVA7, OTU functionality and Stratos monitoring options
•Removable Storage device contains junction specific data allowing fast repair
by card replacement and storage device transfer
•Extended features licensed through encrypted license card
•Integrated Ethernet interface
•USB interfaces for handset, memory devices, and license card readers
•The ST800/ST900 Extended System Bus interface is no longer provided on
the ST950 which means that the IRM, OTU Card, SDE/SA Card no longer
supported
2.2 System Components
CPU Card
The CPU Card performs all high level control functions for the junction and
communicates with the peripheral I/O cards using high speed serial communication
protocols. The physical interfaces are the same as those used in the ST900 family
of controllers. An updated I/O card protocol improves system performance and adds
functionality. This protocol is known as GSPI - Generic Serial Peripheral Interface.
Older I/O cards will need to be updated to allow communication with the ST950.
ST950 compatible I/O cards are easily recognized by the text 'I/O CARD
667/1/32990/95x' printed on the board cover.
ELV Lamp Switch Card(s)
ELV Lamp Switch cards (LSLS) provide 32 undedicated switched outputs. The
cards and are located within the cabinet and are plugged into a backplanes that
terminates the street cables. Very large intersections may have additional Lamp
Switch, I/O and Intelligent Detector Backplane cards located in an adjacent cabinet
for ease of installation and maintenance.
Power Supplies
The High Power Unit (HPU) module distributes the 48V lamp supply from the Lamp
Supply Transformer to the LSLS cards and incorporates the Dim/Bright, A and B
relays. This module is mounted on the left hand side of the cabinet close to the
lamp supply transformer.
The Logic Power Unit (LPU) module provides logic supplies to the CPU Card and
I/O cards and is housed within the 19” logic rack.

I/O Cards
I/O cards take a number of forms, all of which are GSPI peripherals:
•24in 16out panel mounted module - 667/1/46085/001
•24in 4out panel mounted module - 667/1/46085/002
•Intelligent Detector Backplane - 667/1/32910/950
•ST950 CPU I/O kit 24in 4out - 667/1/46014/000
•WiMag Standard Interface kit - 667/1/47210/100
The panel mounted modules 667/1/46085/xxx are mounted on the rear panel of the
controller cabinet and allow direct termination of street cabling without resorting to
the use of additional terminal blocks and soft wire conversion kits.
The ST950ELV CPU I/O card cannot be used in a standard ST950ELV cabinet, it
can only be used in 3rd party cabinets.
The Intelligent Detector Backplanes are mounted in the rack. These provide support
for the connection of up to 4 standard Loop Detector Cards such as Siemens SLD4.
The Backplane connects via a ribbon cable to the Loop Termination Board mounted
on the cabinet rear panel. The Loop Termination Board provides the termination
point for 16 Loop Feeder pairs without the use of additional terminal blocks and
twisted wire kits.
All Loop Detector Cards are powered from a dedicated output of the HPU.
The main components of the ST950 ELV system are shown in Figure 1.
