Page 14: Tc12 System Overview
• Added “Also see the ERD command” to notes on section 3.3.3.67 TC12 SYSTEM OVERVIEW TC12 is a telecommunications system designed for Urban Traffic Control (UTC). It consists of a number of Outstation Transmission Units (OTUs) positioned in the traffic controllers or detector cabinets. These communicate with a central office containing a number of Instation Transmission Units (ITUs).
Page 15 TC12 Installation, Commissioning & Maintenance Handbook the ITU cabinet but there is also the option of driving a remote SIP. The ITU can also be used to drive a TC8 Instation. There is also facility for an Instation Test Set which can be used to measure signal levels and monitor communications (both data and errors) on the telephone lines.
Page 16 The PSU board supplies power to the ITU rack. It also interfaces between the PC and the SIP and allows connection to a TC8 ITU rack. This facility would be used should a TC8 system be expanded with TC12. 666/HE/43100/000...
Page 17 TC12 Installation, Commissioning & Maintenance Handbook Digital Output Rack The Digital output rack contains one Instation rack Power Supply Card and between one and sixteen Digital Output boards, each capable of driving 64 LEDs at up to 30 V 25 mA. There are two variants of Digital Output board, one sources current and the other sinks current.

TC12 Installation, Commissioning & Maintenance Handbook 2.2.3 Systems Fault Indication Panel (SIP) The SIP (part number 667/1/22667/000) is 6U high and is screwed to the Instation racking in front of the PC. If the Audible alarm on the system fault indication panel (SIP) sounds it should be cancelled as required from the UTC TCC terminal.

The earth strap comes with a bolt (+ star washer) and tag on one end which is attached to the hole situated below the power supply on the PCB (see Figure 7 for position of ground hole).
Page 34 TC12 Installation, Commissioning & Maintenance Handbook S3 - Audio ON/OFF This switch should normally be set to on. If it is set off then LED LP2 will light once the board is powered up and the local SIP audio alarm will not sound in the event of any faults.

TC12 Installation, Commissioning & Maintenance Handbook Voltage Monitoring Transformer A Voltage monitoring transformer (part number 667/7/25172/000) is used per Outstation when equipped with LMU facilities. The red and black wires connect to the lamp supply mains live and neutral being monitored (Red to Live and Black to Neutral).

TC12 Installation, Commissioning & Maintenance Handbook COMMISSIONING 6.4.1 Commissioning Procedure after Power Up 1. Initialisation The operator can initialise just the Integral OTU, just the Controller, or both together by using the appropriate handset command value: Initialising OTU only: Enter CNN=117, LRN=53 and TKE=199.

TC12 Installation, Commissioning & Maintenance Handbook Check that the status LEDs illuminate correctly, see section 6.5.1. 6.4.2 Configuration Using the Handset With the Controller and OTU powered up, connect a handset terminal to the Controller Main Processor handset socket. The Integral OTU is configured using a subset of the commands used to configure the Freestanding OTU.
Page 191 Subsection No Subsection No. The PC in the TC12 Instation Test Set can be used as a handset terminal - Refer to section 4.6. The PC keyboard makes entry of commands easier than with a conventional handset terminal. Alternatively a conventional handheld handset terminal (the same type as used to configure controllers, part number 667/4/13296/000) can be used.

Page 193 TC12 Installation, Commissioning & Maintenance Handbook The power is turned off and back on, or The OTU is re-initialised using the three reset commands. Bit 2: The Integral OTU/LMU has appeared to have failed or is not connected and integral RLM is configured. This will switch the lamps off and not allow them back on even if the OTU/LMU has come back on line.

Normal examination of the OTU's fault logs should be made using the OTU commands 'GLF' and 'GLD' rather than these engineering commands.

TC12 Installation, Commissioning & Maintenance Handbook ENG 203 - 210 0 to 255 OTUSRx - Integral OTUs shared RAM sections 0-7 These eight codes can be used to display any byte within the shared RAM interface between the Integral OTU and the controller. For ease of use, it is recommended that the 'ENO' command is used rather than this one.

Page 200 TC12 Installation, Commissioning & Maintenance Handbook The learning of the second state is automatic once the controller has been switched to that state and requires no manual intervention. This means that it is not strictly necessary to manually switch the controller into the other state as the second learning sequence will be invoked automatically at the first dim/bright change, after the initial learning sequence was invoked.

TC12 Installation, Commissioning & Maintenance Handbook MAINTENANCE 6.5.1 Status LEDs LEDs are provided on the front edge of the board to provide basic status information. The position of these LEDs and their functions are shown in Figure A System fail on the Controller Main Processor PCB may indicate a fault on the Integral OTU PCB.
