  • Page 4 ST950S Plus+ Installation and Commissioning Manual DANGER: 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 appropriate traffic management and is signed at the junction area to warn motorists and pedestrians of any dangers and to help protect the personnel working on the site.
  • Page 5 DANGER: Important Plus Considerations To provide the most reliable operation, the Siemens ST950S Plus controllers use a DC supply. To maintain all street voltages within ELV limits, equipment outside the cabinet must be supplied with voltages within the band 0 to +48V DC with respect to earth. Voltages beyond that will result in overall voltages within the system being in excess of the ELV limit as defined by BS7671.

  • Page 26: St950S Plus+ Introduction And Basic Principles

    2. ST950S Plus Introduction and Basic Principles The Yunex Traffic ST950 Plus system is part of the wider ST950 family of controllers and associated equipment. The ST950 Plus system will run very similar firmware and offers same facilities as the rest of the ST950 family, including license enabled integral MOVA and integral UTMC OTU facilities.

  • Page 27: St950Splus+ System Components: An Overview

    ST950S Plus+ Installation and Commissioning Manual Figure 2. System Overview On the street, the armoured street cables terminate at a “Pole Top Board” (PTB) within the Traffic Signal Pole, located inside the Pole Cap. An option for mid-level or low-level access poles is also available (using a 16-way protected terminal block assembly, 667/1/58200/026).

  • Page 28: St950 Cpu Card

    ST950S Plus+ Installation and Commissioning Manual 2.1.1. ST950 CPU Card The CPU Card performs all high-level control functions for the junction and communicates with the peripheral I/O cards and CIC cards using high speed serial communication protocols. The physical interfaces are the same as those used in the existing ST950 family of controllers. The ST950 family use an updated I/O card protocol which improves system performance and adds functionality.

  • Page 30: Smartloop Modules

    ST950S Plus+ Installation and Commissioning Manual Important: The controller monitors the status of all nodes and if any phase loses all signals (equivalent to the failure of an aspect drive in a conventional controller), the controller will register a compliance failure and extinguish all signals on controller, or the affected stream if configured. Important: The bypass module must NOT be removed and/or swapped from a RAG assembly without consulting the Technical Support team in the first instance.

  • Page 31: The Principles Of Plus+ Wiring

    ST950S Plus+ Installation and Commissioning Manual Note that: • Both loops of an SDE/SA or U/D pair must be assigned to the same Smartloop device. • N+1 count inputs are not currently supported by Smartloop and must continue to use standard loop detector cards (e.g.

  • Page 32: Stub Pole Wiring

    ST950S Plus+ Installation and Commissioning Manual Figure 4. Principle of Plus+ Wiring The ‘street’ cable is a 2-pair armoured cable. Red and Blue as designated for supply(+48VDC) and the Yellow and Black are data connections (D+ and D-) respectively. Connections between the pole top and nodes (RAG or Ped devices) use a six-way dropper cable. Colour designation is as above with the additional Orange and White (D+ and D- respectively) used to maintain a data loop from nodes back to the Pole Top Board.

  • Page 39: Red Lamp Monitoring

    ST950S Plus+ Installation and Commissioning Manual The IC4 defaults for Reserve State have not been changed for Plus+ Controllers, so: • Junctions with RLM configured to extinguish streams (typically part-time junctions) are still extinguished by default • Stand-alone pedestrian crossings are initially held at vehicle green / pedestrian red but then extinguish if Reserve State remains active for more than 4 minutes.
