TC12 Installation, Commissioning & Maintenance Handbook Instation The Instation comprises of one or more Traffic control computers (TCC) and one or more Instation Transmission Units (ITUs). The ITU cabinets are 32U high with grey panelling and a smoked glass front door. Traffic Control Computer The TCC is a system containing a minimum of one machine and one PC per ITU cabinet. The UTC TCC system communicates with the PC(s) via an Ethernet link.
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. The system could be used for any application requiring digital output, not just wallmap driving.

TC12 Installation, Commissioning & Maintenance Handbook Unused 6U positions are fitted with a 6U blanking panel (561/4/20899/022) 2.2.2 PC The TC12 PC is not like most PCs in that it does not have a motherboard; instead the processor card and the other cards are plugged into a back plane. There are 2 types of TC12 PC which may be used and are described below: 2.2.2.1 Rack Mount PC The Rack Mount PC is a convention desktop style of PC which sits on a shelf in the TC12 cabinet.
PAGE 24
TC12 Installation, Commissioning & Maintenance Handbook 2.2.2.4.2 Rack Mount Wall Map PC A rack mount PC which is to be used for driving the LEDs on a wall map would normally have the following, additional, cards installed in it. • Ethernet Card (Etherlink 3) (not needed if processor card has built-in Ethernet) • Digi I/O Card (1 per digital output rack) 2.2.2.4.
PAGE 25
TC12 Installation, Commissioning & Maintenance Handbook keys are then used to select the items to change; only the Interrupt Request Level and the Base Address can be changed. The parameters should be set to the values shown below: I/O Base Address 300H Interrupt Request Level 3 Note: If an Etherlink 3 card is to be used in a PC with a built-in Ethernet connection the Etherlink 3 card settings must be those in 2.2.2.

PAGE 29
TC12 Installation, Commissioning & Maintenance Handbook The software installation procedure is as follows: SAFETY NOTE The PC should be plugged directly into the mains, and not via the mains distribution panel on the Instation, since the Instation has not undergone on-site safety tests, described in the commissioning section, at this stage. Figure 4 - TC12 Instation PC Installation Screen (7.
PAGE 30
TC12 Installation, Commissioning & Maintenance Handbook (1) Before starting the TC12 software installation the Ethernet connection should be configured using the instructions given in 2.2.2.5 or 2.2.2.6, as appropriate. (2) Insert the TC12 Software disk into the PC and then switch the PC On. The Installation software will auto-boot and 'SIEMENS' will be displayed for a short time followed by the TC12 Instation PC Installation Screen, which should look something like Figure 4 if the software is Version 7.
PAGE 31
TC12 Installation, Commissioning & Maintenance Handbook (10) If the indications for the DIGI I/O and IMD cards are as expected, move across to the 'Install' menu, select the 'Yes' option and hit return. The TC12 Software will now be installed on the Hard disk of the PC. Should the DIGI I/O cards and/or IMD cards not be shown as expected then choose the ‘Quit’ option and correct the problem. (11) Exit the Installation software. Eject the TC12 Software disk and keep this as a backup.

Digi I/O, SIP (local and remote), Watchdog and TC8 cables) See Figure 7 for a diagram of the board layout showing the position of connectors, LEDs, switches, volume control. SAFETY NOTE When installing the PSU PCB in the TC12 Instation cabinet the earth strap should be bolted on to the PCB before the mains cable is plugged into the PCB.
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. If the Audible alarm on the system fault indication panel (SIP) sounds it should be cancelled as required from the UTC TCC terminal.

It must monitored using a voltage sensor. Other phases in the stage with phase D may still be monitored (i.e. Phase F) using 'G' bits, providing that they meet the normal requirements. Note that voltage sense transformers are normally assigned sequentially starting at digital input 31 and working back through 30 etc.

It can be used at all the TC12 baud rates and at any signal level between 0dBm and -63dBm. There is a pair of headphones that may be connected to the ITS to allow the user to listen to both control and reply messages.

PAGE 161
TC12 Installation, Commissioning & Maintenance Handbook By checking each OTU in turn and checking the errors it should be possible to determine where the fault lies or what the next step to take is. If errors are detected in monitor mode it is best to obtain authority to take all OTUs on that line off line and re test in Outstation mode. If the fault appears to lie with the OTUs in the field or the line, then testing at the OTU using the test will determine if it is the line, the OTU or other OTUs.

Using the OTS in OTU mode will affect transmission since the OTU input/output cable is detached from the OTU. This forces all OTU inputs to the "1" state and this will be transmitted to the Instation.

TC12 Installation, Commissioning & Maintenance Handbook Return MODE and TC switches to the OFF position. Switching the TC switch OFF at any time simulates the word fail condition on the reed interface of the OTU, thus causing the traffic controller to revert to local operation independent of the test unit.

The position of these LEDs and their functions are shown in Figure 34. A System fail on the Controller Main Processor PCB may indicate a fault on the Integral OTU PCB. If the system fail LED is on, information about the type of fault that has occurred can be accessed using a handset terminal (see section 6.4.2 on handset commands).

TC12 Installation, Commissioning & Maintenance Handbook (4) S4 - 600 Ohm/High Impedance Switch If the switch is set to high impedance when it should be set to 600 Ohms, the transmit signal for all OTUs on the line and the receive signal for the particular OTU will be up to 3dB higher than if the switch was set correctly. The characteristics of the line may also be affected.
