Safety InstructionsR&S® TMU919System Manual 2600.5423.02 ─ 012.3 Special Hazard Information2.3.1 Hazards from AC Supply VoltageAll voltages of Urms > 30 V AC or U > 60 V DC must be regarded as constituting a shockhazard. When working with voltages that constitute a shock hazard, appropriate meas-ures must be taken to prevent exposure to danger. Never work on live components. Workon live parts should only be performed in exceptional cases and only if special safetyprecautions are taken.2.3.1.1 AC Power Supply●Before connecting the AC power supply, it is important to ensure that the power sup-ply specifications given for the system or instruments match the nominal specifica-tions for the local power supply network. The power supply circuit must be protectedby means of fuses in order to prevent overloads and short circuits.●Miniature modules have neutral conductor fuses. As a result, the power supply maystill be connected even after interruption of the circuit by a fuse.2.3.1.2 Changing Fuses●Fuses which are accessible to the operator should only be changed after the instru-ments have been disconnected from the power supply. They must always be replacedwith fuses that have the same electrical rating, tripping characteristics and breakingcapacity.●Motor protection switches and automatic line fuses in those parts of a transmittersystem that can be accessed by users must be tripped. If their response range isadjustable, the ex‑factory setting must not be altered. If settings are changed inad-vertently, the correct values specified in this documentation must be set.2.3.2 Hazards from High‑Energy Electric CircuitsThe instruments contain low-voltage circuits that can be fed from a voltage source withan extremely low impedance (e.g. amplifier operating voltage). These circuits carry dan-gerously high levels of energy. At Rohde & Schwarz, we treat these circuits in the sameway as circuits with hazardous contact voltages. Normally, these circuits are protectedby covers to prevent unintentional contact. The cover has a warning label.In practice it has been repeatedly shown that short circuits caused by small metallic toolsresult in severe burns. For safety reasons, any high‑energy electric circuits in areas ofthe equipment that can be accessed by users are concealed by protective covers.●Exercise the same amount of caution for measurements on low‑impedance voltages(e.g. for repair purposes) that you would when performing measurements on oper-ating voltages which constitute a shock hazard.Wear suitable protective gear when necessary. Special Hazard Information
Safety InstructionsR&S® TMU920System Manual 2600.5423.02 ─ 01●Before opening any equipment or removing a particular cover, turn off the powersupply and wait 5 minutes to ensure that capacitors have discharged sufficiently.●Do not discharge capacitors by short‑circuiting them.2.3.3 Hazards from RF Radiation2.3.3.1 Obligation to Instruct Personnel●The operator must train all personnel in the operation of this transmitter or instrumentin line with EN60215 and/or IEC215. It is essential that these regular training sessionsemphasize the dangers related to high frequency that exist at the respective trans-mitter or instrument. Operating personnel are only authorized to adjust and operatethe equipment after they have completed the respective training sessions and theirparticipation has been documented.High‑energy RF circuits inside the transmitter or instrument are routed via conventionalremovable RF connectors (e.g. type N). Depending on the output power, the output portsof the transmitter and instrument are equipped with screw-type or plug-in RF lines orducts.If RF lines or modules carry high power, the connection point or the entire module istagged with the general danger warning label (yellow triangle with a black exclamationmark).2.3.3.2 RF ShieldingTransmitters and instruments from Rohde & Schwarz are shielded so that even in theimmediate vicinity there is no danger from RF radiation when all RF lines are connected.This applies to statutory provisions in Germany, i.e. the regulation concerning electro-magnetic fields:Limits for electrical and magnetic field strengths of high‑frequency installations aredefined in the 26th ordinance of the German Federal Government's Emission Control Actof December 16, 1996 (26. BImSchV).2.3.3.3 Rules When Operating an AmplifierDisconnecting RF lines that are in operation can result in arcs. These can cause burnsand eye injuries.●Operation of the amplifier is only permitted if a main or dummy antenna is connected●Never disconnect RF lines when the amplifier is in operation●Never open the amplifier or modules when the amplifier is in operation●Never operate the amplifier if RF lines are exposed Special Hazard Information

In contrast to the dual-drivesolution, with the backup drive a TCE900-System Control is not necessary. By default,the program exciter (R&S TCE900 program exciter) is connected to the output stage andsupplies the modulation signal. The control exciter (R&S TCE900 control exciter) moni-tors the program exciter and switches to the output stage if the program exciter fails.

As an option, the two-pin switches can also be connected with the auxiliary con-tacts (each 1 phase and N). The individual phases are routed from X1 to main switch Q1via cable W1E. Q1 enables the total load to be switched on and off at all poles.The voltage is routed with three phases from Q1 to overvoltage protection A101, whichcontains one overvoltage arrester for each phase. Any overvoltage is diverted via W1Tand X1.PE to PE.Via W1T, the individual phases L1, L2, and L3 are each routed to circuit breakers F1 toF20, so that 230 V are present there with respect to N. The outputs of the circuit breakersare connected to output terminal strip X2 via cables W2A, W3A, and W3B. A max. of 20loads are connected to X2.Thus each load is protected against overcurrent by a circuit breaker. Circuit breakers F1to F6 trigger at 20 A and serve to protect the amplifiers. Circuit breakers F7 to F20 triggerat 6 A and serve to protect the TCEs, the fans of an exhaust kit (optional), or any customerinstruments.Standby power supply (with amplifiers)If an optional standby power supply is installed for an amplifier, the main and standbypower supplies operate in parallel, each at half power. If one of the two power suppliesdrops out, the functional one operates as the power supply at full power.Amplifiers not including a standby power supply are connected to L, N, and PE (networkoutput terminal X2) using a 3-wire cable. When using a standby power supply, a 5-wirecable is used to connect to L1, L2, N1, N2, and PL1, since now the main and standbypower supplies are protected by a separate circuit breaker.3.1.5.2 Transmitter Control UnitThe transmitter control unit contains the following components:●R&S TCE900 SysCtrlThe transmitter control unit is responsible for both internal and external communications,including all control functions.

The command can be inputat connector pin 1 of connector 101A.Command InputsAll command inputs are operated via optocouplers with a floating supply voltage that isgenerated on the module. A command input becomes active by means of a connectionto the common command line. Both continuous signals and pulse signals are permitted.With pulse signals, a minimum pulse length of 100 ms must be ensured. With continuousoperation, the signal which became active last is rejected in the case of mutually exclusivesignals.Example: The TRANSMITTER ON command is valid and the TRANSMITTER OFF com-mand is issued. The TRANSMITTER OFF command stays invalid for as long as the firstON command is active. The command inputs are distributed between two 25-pin D-Subsockets (X101A, X101B).Message OutputsAll message outputs are implemented by means of floating relay contacts. A message isvalid when the contact is in its closed state. Normally-open (NO) contacts and, to a limitedextent, normally-closed (NC) contacts are available for this purpose. Relays with bistableswitching characteristics are reserved for the local/remote messages of the correspond-ing function groups.The module can be used universally for FM, DAB, and TV transmitters. It contains theconsecutively numbered commands COMMAND 1 to COMMAND 32 and the consec-utively numbered message outputs MESSAGE 1 to MESSAGE 80.Assignment to Transmitter FunctionsThe messages or commands are assigned to the transmitter functions according to theused configuration via a routing program stored in the higher-level control unit. Duringthe configuration phase, this program assigns the command inputs and message outputstheir logical meaning according to the functional use of the module.Communication between Remote Control Interface and TransmitterData is exchanged with the R&S TCE900 SysCtrl unit via an internal CAN bus. Thetransmitter control unit also provides the operating voltage for the remote control inter-face.CAN BusThe remote control interface has an internal 9-pin CAN bus D-Sub plug X1 and a 9-pinCAN bus D-Sub socket X11. The module receives its power supply (+12V) via the CANbus plug X1.Design and Function R&S TMU9
Transmitter System R&S TMU9R&S® TMU939System Manual 2600.5423.02 ─ 01Single Transmitter and Standby SystemIn a single transmitter, the remote control interface is directly connected to the TCE900SysCtrl via the CAN bus plug X1. The X11 socket remains free.In standby systems, the CAN bus is connected to further n+1 modules via X11.3.1.5.11 Exhaust Kit (optional)The exhaust kit allows the transmitter to be connected to a central ventillation system atthe transmitter station or for the hot air from the transmitter to be vented directly outside.Two differential pressure sensors (1) are used to measure the pressure inside the frameenclosure with reference to the outside air pressure. Through the ACIF of the TCF, theRPM of the two fans (2) are regulated with the aim of maintaining normal air pressurewithin the enclosed frame.Fig. 3-10: Mutli Tx transmitter with exhaust kit1 = Differential pressure sensors2 = Fans Design and Function R&S TMU9
Transmitter System R&S TMU9R&S® TMU940System Manual 2600.5423.02 ─ 01This option cannot be ordered separately and subsequently installed in the transmittersystem, since some modules or components have to be preassembled at the factory.The cooling system consists of the following modules or components:●Exhaust kit TM9-C1– Fans E1, E2– Differential pressure sensors S1, S2–Temperature sensor B2– Exhaust air transfer duct●Air cooling interface (ACIF) (option to the TCE900 TxControl transmitter control unit)The air cooling interface (ACIF) is used to establish the connection from the TM9-C1exhaust kit to the TCE900 SysCtrl unit. The ACIF serves in part to control speed andmonitor the fans and, where appropriate, to send error messages to the TCE900 SysCtrl.Pressure sensors S1 and S2 measure the pressure inside and outside of the rack. Thus,a pressure-neutral environment can be configured in the rack. Temperature sensor B2measures the exhaust air temperature in the vicinity of the exhaust air transfer duct.Mains distribution unit ZR900Z10 protects fan E1 via circuit breaker F7 and fan E2 viacircuit breaker F8.3.1.6 Performance FeaturesEfficiencyThe efficiency of a transmitter is correctable. This readjustment of the transmitter effi-ciency is done by modifying the DC supply of the power amplifier.To get an idea for transmitters that are not operated at the nominal power, the followingestimation is permitted.Unew=√(Pnew/Pnom)*UnomHere, a linearity precorrection found at nominal power does not yet have to be adapted.Uninterruptible power supplyTo bridge extended power supply faults, the control and signal processing componentspresent in the transmitter are equipped with a separate supply. The following options areavailable for an uninterruptible power supply:●The "external UPS feed" optionThe external supply can be switched off via the main switch and supplies the trans-mitter control unit components and the exciters. Alternatively, one or more UPS devi-ces can be installed in the option section of the rack. The UPS devices are 19" rack-mounts with 1 HU.●The "internal UPS" optionThe "internal UPS" option uses a UPS (additional purchase part) as a 19" instrumentrackmount with 1 HU. The 3 free rack units (option section) are intended as the Design and Function R&S TMU9
Transmitter System R&S TMU9R&S® TMU941System Manual 2600.5423.02 ─ 01defined installation location. This means it is not possible to equip all exciters and thetransmitter control unit with an independent UPS for MultiTx in the full configuration.●The "redundant voltage supply for the transmitter control unit (TCE900 CTRL)" optionThe transmitter control unit (TCE900 CTRL) has an optional "external supply" rack-mount for an "+12 V external" supply.Emergency modeIf the transmitter control unit has failed or communication with the transmitter componentshas been interrupted, the system is in emergency mode.This means the last operating states in all system components are saved to nonvolatilememory, with exception of the power amplifiers, for which the operation settings aresaved only until the next restart. When restarted, the amplifiers are re-commanded bythe active exciter.The system components maintain this operating state until other states are commandedby a new/repaired/replaced transmitter control unit.3.1.7 Power Display and Reflection MonitorDisplaysThe displays of the transmitter show the forward and reflected power of the transmitteroutput. The forward and reflected power is displayed with an accuracy better than ± 5 %of the nominal value.RF forward monitoring and messagesFor nominal power up until the warning level, the transmitter sends the messages RF ONand RF OK.If the configurable warning threshold (0 dB to -20 dB) is undershot, the transmitter sendsthe RF ON message and an additional warning message (RF WARNING). The RF OKmessage is canceled.If the configurable fault threshold (0 dB to -20 dB) is undershot, the transmitter cancelsthe RF ON message right away and issues an RF fault (RF FAIL) after a configurablewaiting period (1 s to 20 s).Reflection warningA warning threshold is set to generate a reflection warning.The warning threshold lies between -18 dB and -28 dB and is the return loss in dB.Reflection faultThe transmitter is switched off when the return loss is –17 dB to -14 dB (configurable)(corresponds to 1/50 to 1/20 of the forward power). It can be switched off by blocking theRF (RF carrier loop). Design and Function R&S TMU9
