SAFETY General Rules for Treatment for Burns, Bleeding, and Shock 1. After casualty has revived, treat for injuries and shock. 2. Reassure casualty. 3. Try to make him comfortable. 4. Keep him reasonably warm but do not apply heat. 5. If thirsty, liquids may be given but no alcohol (no liquids should be given in cases of severe burns). 6. Treat burns or wounds. Infection danger in treating burns or wounds is very great so ensure hands are

clean and do not handle affected areas more than necessary. 7. Do not apply salves, grease, etc. to burns. 8. Do not remove burned clothing that adheres to the skin or breaks blisters. 9. Cover the burn with a dry sterile dressing, piece of sheeting, etc. 10. Bandage lightly over blisters where care must be taken to cover and not to break. 11. If wound is bleeding severely, elevate affected area, except in the case of a fracture. 12. Expose wound and apply pressure. 13. Apply dressing, pad and bandage. 14. For burns and bleeding, immobilize injured part using splints if necessary and keep patient in restful

position during removal to hospital or expert medical attention. 15. In all cases, send for medical aid immediately.


SAFETY Electric Shock - Rescue Methods Electricity can damage the body in a number of ways. It may interfere with the proper functioning of the nervous system and the heart action, subject the body to extreme heat and can cause severe muscular contractions. The path that the current of electricity takes through the body is important. Currents that pass from hand to hand or from hand to foot may pass directly through the heart and upset its normal functioning. This threat to life is related to the amount of current or amperage that will flow through a victim's body. Very little current (as little as 10 mA) can result in severe shock or death. Speed in the application of first aid measures is absolutely essential in cases of electrical injury. As soon as the victim is freed safely from the source of the electrical current, artificial respiration should be commenced immediately if breathing has stopped. If the carotid pulse cannot be felt, external cardiac massage should be commenced simultaneously. Resuscitation should continue until the patient is breathing on his own or until medical aid arrives. Survival rates can be quite high if cardiopulmonary resuscitation is started within 3 to 4 minutes of the injury being received. Act At Once - Delay or Indecision May Be Fatal 1. Turn OFF the electrical source. 2. Commence artificial respiration immediately. 3. Treat for burns, bleeding and shock. Removing a Casualty From Electrical Contact LOW VOLTAGE - 0 to 240 volts (household use) Switch off the current, if possible and time permits. If the switch cannot be located immediately and the supply is through a flexible cord or cable, the current may be shut off by removing the plug or even breaking the cable or wrenching it free. Never attempt to shut off current by cutting cord with a knife or scissors. If the current cannot be shut off, the greatest care is necessary in removing the casualty. Household rubber gloves, rubber or plastic hose (if there is no water in them), a dry unpainted stick or a clean dry rope can be used to free victim. HIGH VOLTAGE - 240 volts and up (industrial machines and power lines) Do not touch any person or equipment in contact with a wire. Use a dry unpainted pole, clean dry rope, dry rubber or plastic water hose to separate the casualty from the contact. Keep as far away as possible. Do not touch the casualty until the casualty is free.


SAFETY Toxic Hazard Warning There are devices used in this equipment containing beryllium oxide ceramic, which is non-hazardous during normal device operation and under normal device failure conditions. These devices are specifically identified in the equipment parts list(s). DO NOT cut, crush or grind devices because the resulting dust may be HAZARDOUS IF INHALED. Unserviceable devices should be disposed of as harmful waste.

V1 REPAIR MANUAL Section 2 THEORY OF OPERATION

2.1 INTRODUCTION The theory of operation for the V1 FM broadcast transmitter is presented in this section. Unique circuits are explained. Where applicable, the detailed theory for a module or assembly is provided in a separate paragraph in this section. A block diagram of the V1 transmitter is provided in Figure 2-3 at the end of this section. Electrical schematics SD-1 through SD-8 in Section 6 provide circuit details. 2.2 TRANSMITTER DESCRIPTION The V1 is broadband and can operate at any frequency between 87.5 MHz and 108 MHz. Table 2-1 indicates continuous RF power capabilities for all modes of operation. Table 2-1: RF Output Power Ratings Mode Power (W) Analog (FM) 1,400 (max.)

1,250 (rated) 30 (min.)

Hybrid (FM+HD) 1,000 (max.) 900 (rated) 130 (min.)

All-Digital (HD) 400 (max.) 360 (rated) 65 (min.)

The V1 may be operated locally where the V1 and studio are co-located or remotely where the V1 and studio are located at different sites. The V1 consists of three major stages: ac-dc power stage, RF stage and control/monitor stage.

2.3 AC-DC POWER STAGE See Figure SD-1. The ac-dc power stage converts the ac power source to a positive dc voltage (PA volts) for the V1’s RF power amplifiers. It also provides the V1’s regulated +24 V, ±15 V and +5 V supplies. The main components of the ac-dc power stage are the control/interface PWB A1, PS interface PWB A2, LVPS module U2, power supply module U3 and +12 V fan power supply U8. 2.3.1 Ac Input The ac input is applied to U1 on the back panel. Switch S1 controls the application of the ac voltage to the switching power supply module (U3, via PS interface PWB A2) and LVPS module U2. The V1 accepts an input between 180 and 264 V ac, 47 to 63 Hz. 2.3.2 Switching Power Supply Module See Figure SD-1. Switching power supply module U3 converts the ac input to the regulated PA volts supply for power amplifier (PA) PWBs A (A3) through D (A6). The module provides up to 2120 W output, at maximum levels of 53 V and 40 A. The module regulates the output voltage based on a PA Volts Control input from the control/monitor stage. A PA Volts Sample of the voltage is applied to a test point on PS interface PWB A2 for monitoring. The module has a built-in cooling fan and senses out-of-regulation and excessive temperature conditions and applies PS Fail and Supply Temp alarm signals to the control/monitor stage. Both conditions trigger an inhibit signal from the control/monitor stage to shut down the power supply, thus inhibiting the RF output.

2 V1 Repair Manual Issue 2.2 Section 2 Theory of Operation

2.3.3 LVPS Module See Figure SD-1. LVPS module U2 converts the ac input voltage to the regulated low voltage dc supplies (+24 V, +15 V, +5 V and -15 V) applied to the control/monitor stage. 2.3.4 +12 V Fan Power Supply Module See Figure SD-1. Fan power supply module U3 converts the ac input voltage to the +12 V dc supply used by cooling fan B1. 2.3.5 Power Supply Interface PWB See Figure SD-1. Power supply (PS) interface PWB A2 provides an interface for all inputs (ac voltage, PA volts control, power supply inhibit) and outputs (PA volts, high temperature, power supply failure, ac failure) of switching power supply module U3. Test points are available to monitor the PA voltage, the power supply inhibit signal and the high temperature and power supply failure alarms. 2.4 RF STAGE See Figure SD-1. The RF stage accepts the RF input from an external RF drive source and generates the final RF output. It consists of RF drive splitting circuitry (part of control/interface PWB), four power amplifiers (A3 – A6), reject load PWB (A7), common point PWB (A8), a low-pass filter, power probe PWB (A9) and cooling fan B1. 2.4.1 RF Drive Impedance Matching/ Splitter Circuit See Figure SD-5. The control/interface PWB (A1) contains circuitry that accepts the external RF drive source and provides four equal RF drive signals for the RF power amplifiers. The external RF drive source (exciter) provides the RF In signal (J21). This signal is applied to an impedance matcher comprised of a 75 Ω Zo coaxial cable and coaxial cables T1:A and T1:B. These cables act to match the impedance between the RF In input and the splitter common point. Four equal signals are provided at connectors J17 through J20 to drive the PAs.

2.4.2 RF Drive Sample See Figure SD-5. The control/interface PWB (A1) contains circuitry that provides an RF drive sample voltage. A short section of micro-strip transmission line is in close proximity to the RF In input. Due to the proximity and orientation to the micro-strip, an RF voltage representative of the RF drive is induced in a power probe circuit. The RF drive signal is peak detected by A1CR4, A1R37, A1C60 and associated components. A dc voltage, proportional to the RF drive level, is applied to ADC A1U31 (pin 1) and to the RF DRV test point (TP12). The sample is used by monitoring and protection circuits. 2.4.3 Power Amplifiers See Figures SD-1 and SD-7. Each power amplifier PWB (A3 through A6) contains an identical, broadband, push-pull, RF power amplifier (PA). Each PA provides 375 W (nominal) of RF power in the FM band (87.5 to 108 MHz). The RF Drive, PA Volts and Bias inputs are provided by the control/ interface PWB (A1). Cooling air for the power amplifiers is provided by fan B1. The RF Drive input is applied to cable T1, which is connected as a balun to provide balanced, 180° out-of-phase, RF drive signals to the individual gates of dual N-channel power MOSFET (Q1). Cables T2:A and T2:B, as well as capacitors C2, C6 and C7, inductor L2 (part of R12/R13 leads) and resistors R5, R8. R9, R10, R12 and R13 provide impedance matching, which transforms the 50 Ω input to low impedance for application to Q1. The B+ (PA) voltage is applied to the individual drains of Q1 via inductors L4 and L5, which provide proper resonating reactance for Q1’s output. Cable T3:A and T3:B transform the impedance at the RF output, ensuring an optimum (low) impedance is presented at Q1’s output. Cable T4 converts the balanced RF signal to an unbalanced RF Output signal.

V3/5 Repair Manual Page 2-3 Section 2 Theory of Operation Issue 2.2

The PA voltage input is applied to capacitors C1, C3, C5, C8, C11 and C16, which act as a broadband decoupling network. Capacitor C13 and inductor L3 provide low-pass filtering of the RF signal back to the ac-dc power stage. The Bias input voltage is provided by the control/interface PWB to establish a dc bias current for Q1. The bias current depends on the operating mode. 2.4.4 Reject Load PWB See Figure SD-1. The reject load PWB (A7) provides a means to dissipate reject power between individual PAs. The four PA outputs are passed through the reject load PWB before being combined. Reject power generated by phase and amplitude imbalances between PAs is dissipated in power resistors R1 through R4. Thermistor RT1 monitors the temperature of the reject load PWB resistors and provides a Reject Load Temp signal to the control/interface PWB for thermal protection. 2.4.5 Combining/Filtering See Figure SD-1. The common point PWB (A8) combines the RF outputs from the four PAs to provide a single RF output. The low-pass filter attenuates harmonics and provides impedance matching between the common point (12.5 Ω) and the RF output (50 Ω).

2.4.6 Power Probe PWB See Figures SD-1 and SD-8. The power probe PWB (A9) monitors the V1’s forward and reflected power and generates the Fwd Pwr Sample (A9-A) and Refld Pwr Sample (A9-C) signals applied to the control/ interface PWB for protection and monitoring. The output from the low-pass filter is connected to the final RF Output (A9-G) by a micro-strip transmission line. Due to the probe’s proximity and orientation to this line, RF voltages representative of transmitter forward and reflected power are induced in respective probe circuits. The forward power output is peak-detected by A9CR1 and A9C6 and applied to A9-A. The reflected power output is peak-detected by A9CR2 and A9C5 and applied to A9-C. An RF monitor probe provides the RF Monitor output (A9-F), which is a nominal 1.1 V rms (FM mode at 1,250 W), 0.9 V rms (FM+HD mode at 900 W) or 0.6 V rms (HD mode at 360 W), for use with a modulation monitor or spectrum analyzer. An RF sample probe provides a similar (lower level) sample at A9-E. This sample – for M50 exciters only – is applied to the external exciter for use by the exciters’ adaptive pre-correction circuitry [for hybrid (FM+HD) or all-digital (HD) modes of operation only].


2.5 CONTROL/MONITOR STAGE See Figures SD-1 through SD-6. The control/monitor stage, comprised primarily of the control/interface PWB (A1), performs the following functions: - provides local V1 controls, including a

diagnostic display that also indicates critical levels and alarm events

- contains monitoring and protection

circuits to prevent V1 damage under adverse or fault conditions

- monitors and distributes the RF drive

and the dc supply current to the power amplifiers

- provides remote interfacing for the V1 2.5.1 Front Panel See Figure SD-1. The front panel is the V1’s primary local interface. It contains the local transmitter controls, diagnostic display (GUI) and soft keys, and alarm indicating LEDs. Control and indicators are grouped into three sections of the panel – alarms section, diagnostic display, and control section. See Section 3 of the Installation and Operation Manual for detailed descriptions of each section. 2.5.1.1 ALARMS SECTION The alarms group is divided into four sections. Each section [Output Network (LED 1), PA (LED 2), Power Supply (LED 3) and External (LED 4)] contains an alarm lamp, which turns on when a fault occurs in that section.

2.5.1.2 DIAGNOSTIC DISPLAY The diagnostic display is a graphic user interface (GUI) that is navigated using five soft-keys. The majority of the transmitter’s local control (power presets, local/remote control, etc.) and monitoring (critical parameter levels, alarm events, etc.) may be performed from menus on this display. 2.5.1.3 CONTROL SECTION The control switches determine the V1’s RF status (on or off) and allow for power trim (increase and decrease). The RF on and off switches have integral LEDs that indicate the active selection. 2.5.1.3.1 RF On/RF Off Selection When the RF On button is pressed (enabled in Local mode only), the V1’s RF stage is enabled to provide an RF output. When the RF Off button is pressed, the V1’s RF stage and power supply module are inhibited. 2.5.1.3.2 Power Increase/Decrease Selection When the Power Increase button is pressed (enabled in Local mode only), the V1 enters the Preset menu, where further increase selections will cause the V1’s RF output to increase. When the Power Decrease button is pressed (enabled in Local mode only), the V1 enters the Preset menu, where further decrease selections will cause the V1’s RF output to decrease. Holding either button increases the rate of change of the power set point. 2.5.1.3.3 Local/Remote Status LEDs The Local and Remote LEDs indicate if the transmitter is being controlled locally (via its front panel) or remotely. Local and remote control selection is set up using the GUI.


2.5.2 Control/Interface PWB See Figures SD-2 through SD-6. The control/interface PWB (A1) contains the software systems for transmitter control/ display and remote monitoring. Its microcontroller (CPU) contains 128 KB of FLASH (program) memory, 4 KB of EEPROM and 4 KB of SRAM. There is also an external 32 KB of SRAM. 2.5.2.1 ARCHITECTURE The architecture of the control/display system (see Figure 2-1) is typical for this type of application. The CPU is supported with external memory, analog inputs and outputs, digital input and outputs and a user interface. The SRAM is primarily used to maintain a comprehensive events log. The user interface consists of an LCD display, front panel switches and LEDs. In addition to keeping time, the real time clock (RTC) block has other functions. It interfaces with a coin cell battery and system 5 V to maintain both itself and the SRAM in the event of ac loss to the transmitter. The RTC block also contains a watchdog timer which is essentially a software failure detection and recovery system. When the software is functioning properly, it ‘kicks’ the watchdog timer, resetting it. If the kicking stops, the watchdog timer will eventually overflow causing a hardware reset to the microcontroller and restarting the software.

2.5.2.2 ALARM MONITORING The unique characteristic of the control/ display system is the hardware support for alarm monitoring. ADCs read the level of analog inputs. Comparators generate hardware alarms from the analog inputs (low forward power, high reflected power, etc.) with programmable thresholds set through DACs. The comparator outputs are applied to a CPLD (complex programmable logic device) which generates an alarm interrupt to the microcontroller and forces a shutback of the RF output. The RF output recovers when the alarm condition is removed. 2.5.2.3 ANALOG INPUT CALIBRATION Calibration of analog inputs through the GUI ensures that the displayed metered value is accurate and also ensures that thresholds used for alarm reporting are correct. In the case of analog inputs with hardware comparators, the comparator threshold is an analog signal from a DAC that is adjusted according to the calibration. Other, non-critical, analog inputs are checked in software after being adjusted against the calibration value. 2.5.2.4 MICROCONTROLLER INTERFACE The microcontroller uses two serial buses. The SPI bus communicates with local devices such as the RTC, ADCs and DACs. An external serial bus, also UART based, connects to external equipment.

2.5.2.5 SOFTWARE SYSTEM See Figures 2-2 (a) and (b). The software in the control/display system has three essential functions. The flow diagram in Figure 2-2(a) illustrates the foreground tasks which run continuously at regular intervals. The flow diagram in Figure 2-2(b) illustrates the background or interrupt-driven tasks which run only when an input requires immediate servicing. 2.5.2.5.1 Read Status Task The read status task runs every 200 ms. It reads all of the system status and updates variables for other tasks. It also checks for ‘soft’ alarms which are non-critical in terms of timing but will force an event log to be created and may require an RF shutback. 2.5.2.5.2 RF Power Control Task The RF power control task runs whenever the RF is on and the transmitter is not being inhibited by an alarm. It handles a variety of tasks such as: • RF ramp up and shutback • foldback recovery • automatic level control (ALC) of the PA

voltage (FM mode) • power level control (FM+HD, HD mode) • monitor reflected power and forward

power The ALC function compares the actual RF power to the desired RF power. If the actual power is too high or low, the ALC adjusts the PA voltage to adjust the actual RF power. Shutback is the act of turning off the RF output due to an alarm. The foldback function checks for the alarm condition to clear and then attempts to recover the RF

output to its desired level. When shutback occurs due to high reflected power, a shutback will immediately clear the alarm because of the lack of RF output. As the RF power is restored, the reflected power may also increase. If so, the shutback function will only increase the RF output to a safe level. This is referred to as a foldback condition. The shutback function will continue running until RF power is fully restored. 2.5.2.5.3 Update Display Task The update display task runs every 250 ms. It updates the content on the GUI display. The status bar at the top line of the display is always updated. The middle six lines of the display are updated if they contain active parameters such as meter readings. 2.5.2.5.4 Update Time Task The update time task runs every 500 ms. It communicates with the RTC over the SPI bus to get the current time. 2.5.2.5.5 Internal Serial Update Task The internal serial update task consists of three functions which initiate regular communications with the microcontroller on the exciter to exchange status information. 2.5.2.5.6 Interrupt Tasks The interrupt tasks are used to handle time critical alarms and user initiated soft-key pressings on the front panel. The H/W alarm interrupt sets the shutback flag as a message to the RF power control task to start shutback recovery and calls the read status task to get a snapshot of the system status. The read status task calls the event log function which stores an alarm log.

2.5.2.6 REMOTE INTERFACING The control/interface PWB has several functions related to external serial bus configuration and remote inputs and outputs. It contains customer interface connectors for transmitter remote control and remote alarm/ status monitoring. The following paragraphs provide brief descriptions of these functions. 2.5.2.6.1 Remote Inputs Remote control inputs are provided at back panel REMOTE I/O D-sub connectors (A1J3A and A1J3B) for remote control of the RF status, output power adjustment and selection of presets. These controls are enabled only after remote control has been selected through the GUI’s Control menu. They are operated by applying either a nominal +15 V between the (+) and (-) inputs or a ground to the (-) input (determined by input jumper configuration) of the desired control function. Refer to Section 2 of the Installation and Operation Manual for details on all remote inputs. 2.5.2.6.2 Remote Outputs Remote alarm, status and monitoring outputs are provided on back panel REMOTE I/O D-sub connectors (A1J3A and A1J3B). Alarm and status outputs are presented as logic level signals and are typically active ‘low’ (0 V). Analog voltage samples are provided to monitor critical transmitter parameters (forward and reflected power, PA voltage, etc). Refer to Section 2 of the Installation and Operation Manual for details on all remote outputs. 2.5.2.6.3 Interlock Circuit The XMTR INTLK inputs (pins 1 and 2 of back panel connector A1J4) must present a short circuit to ground when the interlock is intact and the RF output is safe to be enabled, and an open circuit when the RF output is to be inhibited.

2.5.2.6.4 Exciter Link The back panel EXCTR LINK RJ45 connector (A1J1) carries both the internal and external serial bus to allow communication with the digital exciter (for use with Nautel M50 only). 2.5.2.6.5 Microcontroller The microcontroller (U34) performs two roles: • It polls the digital inputs and assembles

their state into a response packet for the control/display software.

• It transfers digital output status information from packets received from the control/display software to the digital outputs.

The microcontroller does not manipulate or act on digital inputs or outputs other than to exchange state information with the control/display software. Digital inputs are polled every 100 ms, therefore a remote input must have a duration of at least 100 ms in order for it to be recognized. Similarly, digital outputs are refreshed every 100 ms. 2.5.2.7 POWER AMPLIFIER INTERFACE The control/interface PWB performs several functions to control and monitor the RF stage: - Monitors the current supplied to each PA

and causes an alarm condition if a PA stops drawing current.

- Splits the RF drive input to each PA and

provides a low level dc signal, proportional to the RF drive power, for monitoring and protection.

- Provides each PA’s dc bias voltage. - Inhibits the switching power supply

module when the appropriate fault occurs.


2.5.2.7.1 PA Fail Detection See Figure SD-5. The voltages across resistors R159, R162, R166 and R168, representative of the individual PA currents, are applied to differential amplifiers U32, U36, U38 and U42. Their output voltages are applied to inputs of ADC U30. CUR1 (TP20) through CUR4 (TP17) test points are provided for monitoring. ADC U30’s output is fed to microcontroller U34. Microcontroller U34 outputs data to 8-bit shift register U8. During normal operation, when a PA is drawing current, the logic ‘low’ output of U8-1 is inverted at darlington IC U6:G output (open collector) to set the PA Fail Alarm output (J3A-2) to its non-alarm state (open collector). If no current is flowing through a PA, U8-1 will switch to logic ‘high’. This turns on darlington IC U6:G’s output and switches the PA Fail Alarm output to its alarm state (current-sink-to-ground). 2.5.2.7.2 PA Bias Voltage Microcontroller U34’s memory contains PA bias voltage settings for analog (FM), hybrid (FM+HD) and all-digital (HD) modes of V1 operation. The bias voltage information is loaded into 8-bit DAC U16. The corresponding analog outputs of U16 are applied through operational amplifiers (U14:A through U14:D) to the Bias 1 (J16-1) through Bias 4 (J16-4) outputs for application to the power amplifier PWBs. If microcontroller U34 causes a PA1 Inhibit through PA4 Inhibit signal (from latches U35:B through U35:E) to become active (logic low), NAND gate(s) U15:A through U15:D will switch to logic high and operational amplifiers U14:A through U14:D will apply a negative bias voltage to the power amplifier PWBs. A PA failure condition will also cause a negative bias voltage to be applied to the associated power amplifier PWB.

2.5.2.7.3 RF Drive Impedance Matching/ Splitter See description in 2.4.1. 2.5.2.7.4 RF Drive Sample See description in 2.4.2. 2.5.3 NxLink Ethernet Interface Module (Optional) See Figure SD-1 or the NxLink manual. An optional NxLink Ethernet interface module (U6) converts the internal serial protocol to Ethernet for external interfacing. When U6 is used, internal transmitter wiring supplies the module’s +15 V power supply, as well as the interfacing to the control/interface PWB and the external LAN (via RJ45 coupler U7). 2.6 COOLING FANS There are two cooling fans in the V1. One fan (B1) is located on the right-hand side, near the front. It is a dual fan that provides cooling air through the RF stage and exhausts air through ventilation holes in the back of the V1. B1 has two tachometer output signals to allow for speed monitoring on each side of the dual fan. Typical fan speed is 6000 RPM. The second fan is part of switching power supply module U3. It provides cooling air for the switching power supply module and exhausts air through ventilation holes in the back of the V1.

V1 Repair Manual Page 3-1 Section 3 Component Level Troubleshooting Issue 2.2

V1 REPAIR MANUAL Section 3 COMPONENT LEVEL TROUBLESHOOTING

3.1 INTRODUCTION This section is intended to assist an experienced electronic technician in fault diagnosis and isolation of a problem to the component level. It is assumed that system level troubleshooting as outlined in the Installation and Operation Manual has been performed and the problem has been isolated to a particular PWB or assembly. Paragraphs 3.2 through 3.4 provide general protection and precaution information that should be followed throughout any component level troubleshooting or maintenance. Paragraph 3.5 and its sub-paragraphs provide maintenance procedures for certain transmitter modules. The modules must be removed from the transmitter to perform these procedures. 3.2 ELECTROSTATIC DISCHARGE PROTECTION The V1’s PWBs/assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge (ESD). The following precautions should be taken when handling an assembly that contains these devices:

NOTE Electrostatic energy is produced when two insulating materials are rubbed together. A person wearing rubber-soled shoes, walking across a nylon carpet or a waxed floor can generate an extremely large electrostatic charge. This effect is magnified during periods of low humidity. This high voltage may damage semiconductor devices such as integrated circuits, field-effect transistors, thyristors and Schottky diodes unless adequate precautions are taken.

3.2.1 Discharging of Personnel Personnel must be electrically discharged by a suitable ground system (anti-static mats, grounding straps) when removing an assembly from the V1 and while handling the assembly for maintenance procedures. 3.2.2 Handling/Storage The assembly should be placed in an anti-static bag when it is not installed in the V1 or when it is not being subjected to maintenance procedures. Electronic components should be stored in anti-static materials. 3.2.3 Tools/Test Equipment Testing and maintenance equipment, including soldering and unsoldering tools, should be suitable for contact with static sensitive semiconductor devices. A 40-watt, temperature controlled soldering iron is recommended. 3.2.4 Stress Current Protection Precautions should be taken to ensure the static sensitive semiconductor devices are protected from unnecessary stress current. This is achieved by ensuring: • Current is not flowing when an electrical

connection is broken. • Voltages are not present on external

control/monitoring circuits when they are connected.

2 V1 Repair Manual Issue 2.2 Section 3 Component Level Troubleshooting

3.3 COMPONENT REPLACEMENT PRECAUTIONS When replacing a part on an assembly or a PWB containing through-hole plating: • Use of excessive heat or excessive

mechanical force can damage the PWB. Multi-layer PWBs are more susceptible to damage than two-sided PWBs.

• DO NOT replace components while the

PWB/assembly is mounted in the V1. • When removing a defective component,

cut the body from the legs before unsoldering the component. This will reduce the heat stress to the PWB’s traces.

• Use a solder removal tool or solder wick

whenever possible to remove the solder from the component’s legs before removing the device.

• Pre-form the legs of a replacement

component to fit the PWB hole spacing. This also applies to ICs that mount in sockets.

• For mechanically fastened components,

such as power MOSFETs, secure the mechanical connection before soldering the legs to reduce the stress on the solder connection.

3.4 SURFACE MOUNT TECHNOLOGY Compared to through-hole component technology, surface mount technology (SMT) enables highly efficient use of board space; however component replacement is more difficult. It is not practical to place SMT components in the V1 spares kit because of their small size. If the repair site is not already equipped to handle surface-mount technology, the following guidelines will aid in component replacement:

3.4.1 Location of Parts SMT components are predominantly on control/interface PWB A1. 3.4.2 Soldering Guidelines The following guidelines may help you when soldering SMT components on a PWB: (a) Recommended soldering aids: • needle tip for soldering iron • SMT solder (low melting point, fine

diameter) • water-soluble, ‘no-clean’ solder flux pen • magnifying glass • steady hand

(b) Clean pads using a solder braid. (c) Apply a thin layer of solder flux on the

pads. (d) For ICs, place the IC on the pads,

noting alignment, and gently press it in place. The flux should have enough adhesion to hold the chip in place.

(e) Carefully solder one corner pin, then

verify the IC's alignment. Solder the opposite corner pin, then verify alignment again.

(f) If alignment is correct, carefully solder

each pin, in order, around the IC. (g) If a solder bridge occurs, use a very fine

solder wick to remove it.


3.5 MAINTENANCE PROCEDURES Module maintenance determines if the subject module’s circuits are operating within defined parameters. The results determine if additional corrective action is required and in most cases will pin point faults to a specific circuit. Maintenance procedures should be performed after: • isolating a fault to the module level (see

Installation and Operation Manual) • removing the module from the V1 • putting the module on a suitable work

surface 3.5.1 Power Amplifier PWB Maintenance Maintenance on a power amplifier PWB consists of a visual inspection of the FET and associated solder connections, PA input checks and the likely replacement of the power amplifier PWB. Troubleshoot defective power amplifier PWBs as follows: 3.5.1.1 TOOLS AND REFERENCE MATERIAL REQUIRED • Digital multimeter • Torque-driver capable of torquing up to

6 inch-pounds (0.67 Newton-metres) • Electrical schematic SD-7 • Mechanical drawing MD-5 3.5.1.2 VISUAL INSPECTION Perform a visual inspection on the power amplifier PWB and its FET as follows: (a) Inspect the dual RF power FET of each

suspect power amplifier PWB for obvious signs of failure such as cracks in the case or overheating of the drain solder joints.

NOTE

Discoloration of the solder connection may indicate overheating of drain solder joints. If discoloration appears, the failure may have been caused by poor soldering.

(b) Check gate drive resistors R12 and R13 for discoloration. This may indicate a FET failure.

(c) Check the solder connection of the

coaxial cable connected to pad C on the power amplifier PWB for discoloration.

(d) Check resistors R3 and R4 and the 14

AWG wire in L1 for discoloration. This may result from PA oscillations.

(e) If there is damage, the entire power

amplifier PWB likely requires replacement. Check for additional possible causes of a failure (see 3.5.1.3) before replacing the power amplifier PWB (see 3.5.1.4).

NOTE

If it is found that the PA PWB is the source of the fault, you must replace the entire power amplifier PWB, rather than an individual FET. Two spare power amplifier PWBs are provided in the V1 spares kit, if purchased. To order a spares kit contact Nautel. Failure to observe this recommendation may void your equipment warranty or cause further failures. (f) If there is no obvious damage, perform

the PA input checks (see 3.5.1.3). 3.5.1.3 PA INPUT CHECKS Check the cabling between the control/ interface PWB’s RF drive splitter output and the suspect power amplifier's input as follows: (a) Disconnect the P1 end of the suspect

PA input coaxial cable(s) (W1 through W4) from the control/interface PWB output (A1J17 through A1J20). Disconnect the P2 end from J1 of the associated power amplifier PWB (A3 through A6).

4 V1 Repair Manual Issue 2.2 Section 3 Component Level Troubleshooting

(b) Use a digital multimeter to measure continuity of the PA input cable(s) removed in step (a). The cable should measure short circuit (near 0 Ω) from core to core and from shield to shield. The cable should measure open circuit from core to shield (both ends). If a measurement does not comply, the PA input cable (W1 through W4) is defective.

(c) If no fault is found with the PA input

cable, replace the power amplifier PWB (see 3.5.1.4).

3.5.1.4 POWER AMPLIFIER PWB REPLACEMENT Replace a defective power amplifier PWB and, if necessary, configure the V1 for the replacement PWB as follows: (a) Ensure the coaxial cable (W1 through

W4) has been disconnected from J1 of the power amplifier PWB.

(b) Unsolder and remove the 16 AWG,

white wire (PA volts) from pad B of the power amplifier PWB.

(c) Unsolder and remove the 22 AWG,

white wire (bias) from pad A of the power amplifier PWB.

(d) Unsolder and remove the blue coaxial

cable (RF output) from pads C/D of the power amplifier PWB.

(e) Remove the two # 4 screws, split and

flat washers securing the FET to the heat sink.

(f) Remove the six nuts, split washers and

flat washers securing the power amplifier PWB to the chassis.

(g) Obtain the replacement power amplifier

PWB from the spares kit, if purchased. Retain the PA Bias Volts Data sheet provided with the replacement power amplifier PWB.

NOTE FETs are static sensitive and must be handled in a static protected manner. (h) Spread a small amount of thermal

compound (Nautel Part # HAG39, from the spares kit), thinly and evenly, on the bottom of the Q1 FET flange on the new power amplifier PWB.

(i) Install the power amplifier PWB on the

six studs on the chassis. Secure the power amplifier PWB to the chassis using the six sets of hardware removed in step (f). Ensure correct orientation (same as the adjacent PWB). Do not tighten the nuts at this time.

(j) Secure the FET (Q1) of the new power

amplifier PWB with two # 4 screws, a flat washer and a new split washer (user provided).

NOTE

You can damage the FET case if you fully tighten one screw while the other is loose. Try to alternate tightening of the two screws to prevent this. (k) Using a torque screwdriver, tighten the

screws to 6 inch pounds (0.672 Newton-meters).

(l) Tighten the six PWB nuts. (m) Solder and reconnect the wires removed

in steps (a) through (d). See Section 5, Wiring Information, to confirm wire positions.

(n) Reconnect the applicable coaxial cable

connector (W1-W4) to the appropriate power control/interface PWB (A1) connector.

CAUTION

Ensure the V1 is in an RF Off state until the PA bias setup is complete.


(o) With the V1 in an RF Off state, enter the Setup PA Bias screen (see 3.6.12.4 of the Installation and Operation Manual).

(p) Select the FET (Q1-Q4) that applies

to the replacement amplifier (see Figure MD-2, noting that PA PWB A3 through A6 correspond to FET Q1 through Q4, respectively).

(q) Using the data from the PA Bias Volts

Data sheet, retained in step (f), enter the Bias voltages for all three Modes, noting the GUI mode names differ from that on the PA Bias Volts Data sheet. For FM mode, use the FM+HD bias voltage; for FM+HD mode, use the IPA FM+HD voltage; for HD mode, use the IPA HD/Discharge or HD/Discharge voltage. Overwrite any previous data.

NOTE

The word “Discharge” is included with the HD modes on the PA Bias Volts Data Sheet, but is not displayed on the Setup PA Bias screen. (r) When complete, Save the new bias

voltage settings. (s) Return the V1 to service. 3.5.2 Reject Load PWB Maintenance Maintenance on the reject load PWB consists of resistance measurements and the likely replacement of resistors. Troubleshoot a defective reject load PWB as follows:

3.5.2.1 TOOLS AND REFERENCE MATERIAL REQUIRED • Digital multimeter • Torque-driver capable of torquing up

to 6 inch-pounds (0.67 Newton-metres)

• Electrical schematic SD-1 • Mechanical drawing MD-2 3.5.2.2 RESISTANCE MEASUREMENTS

NOTE Do not allow the V1 to operate with a faulty reject load PWB. If a fault is suspected, repair the reject load immediately. (a) Remove the V1’s top cover. (b) Desolder the resistor leads from the

reject load PWB. With the leads isolated, use a digital multimeter to measure the resistance of each resistor.

(c) If the resistance measurement is 50 Ω

± 2 Ω, the resistor is OK. If the resistance is short (near 0 Ω) or open circuit, replace the resistor. When installing a replacement resistor, carefully attempt to incorporate strain relief on its leads.

(d) Replace the V1’s top cover. (e) Switch on the AC POWER and return

the V1 to service.

V1 Repair Manual Page 4-1 Section 4 Parts Information Issue 2.2

V1 REPAIR MANUAL Section 4 PARTS INFORMATION

4.1 INTRODUCTION This section contains reference designation lists that provide descriptive and provisioning information for all electrical and mechanical parts that have an assigned reference designation and form a part of the subject equipment. 4.2 FAMILY TREE Figure 4-1 depicts the family tree for the subject equipment. It is based on the descending order of the reference designation hierarchy and identifies all assemblies that have an assigned Nautel configuration control number. 4.3 HOW TO LOCATE INFORMATION FOR A SPECIFIC PART To locate the information for a specific part, the assigned reference designation for the part must be known. In addition, the Nautel configuration control number (e.g., NAPC153/01) assigned to the assembly containing the part or the full reference designation, including the reference designation of all higher assemblies, must be known. 4.3.1 When Nautel Configuration Control Number Is Known When the Nautel configuration control number is known, the information for a part can be located as follows: • Refer to the family tree (Figure 4-1) and

identify the block(s) associated with the Nautel configuration control number. Unless otherwise specified, each family tree block has its own PART NUMBER INDEX TABLE. Locate the part's reference designation in the identified reference designation list in this section, noting they are sorted alphanumerically.

4.3.2 When Ref Des Is Known When the full reference designation is known, the information for a part can be located as follows: • Refer to the family tree depicted in Figure

4-1 with the full reference designation. • Follow the family tree branches to the

block that represents the lowest level assembly assigned a Nautel configuration control number. Then locate the part number index table for that Nautel configuration control number.

• Locate the part's reference designation in

the specified table. 4.4 REFERENCE DESIGNATION LISTS Individual reference designation lists are provided for: • assemblies that are assigned an alpha-

prefixed Nautel nomenclature (e.g., NAPC153/01)

• cable sets that are assigned a numbered

Nautel part (e.g., 204-8402-01) • optional items that are assigned a

numbered Nautel part (e.g., 204-8443) To obtain the full reference designation for a specific part the Nautel configuration control number must be located in the family tree (Figure 4-1) to include the reference designation of all higher level assemblies. The reference designation lists, which are titled and presented in alphanumeric order, are divided into columns to aid in locating specific information.

2 V1 Repair Manual Issue 2.2 Section 4 Parts Information

4.5 COLUMN CONTENT The following paragraphs provide an explanation of the purpose and contents of each column in the part number indexes. 4.5.1 Ref Des Column The ‘ref des’ column contains the reference designation for a specific part. These designations are assigned in accordance with the requirements of American National Standard Specification ANSI Y32.16. 4.5.2 Description Column This column contains the name and descriptive information for each part. The key word is presented first, followed by the adjective identifiers. When the description is 'See Family Tree for Assembly Nomenclature', the associated part is subject to its own part index table or is contained in an optional kit’s list. Look up the reference designation list title (nomenclature) and the reference designation of the associated part in the family tree (Figure 4-1) to determine where to locate its part information. 4.5.3 Nautel # Column This column contains the Nautel number assigned to each part. This number is Nautel's drawing number for Nautel manufactured parts, Nautel's configuration control number for assemblies that are under configuration control management, or Nautel's inventory management number for purchased parts. When a Nautel configuration control number (e.g. NAPC*) is referenced in this column, the associated ref des item is subject to its own part index table. 4.5.4 Vendor # Column This column contains an original equipment manufacturer's part number for a part. A single part number is listed for each part, even though there may be more than one known manufacturer. The listed number is Nautel's usual or preferred choice. The use of this number does not restrict Nautel from selecting and using commercial equivalents during manufacture, where their use will not degrade circuit operation or reliability.

4.5.5 OEM Code Column This column typically contains a five digit coded group as the original equipment manufacturer's (OEM) identifier. The code was extracted from Cataloging Handbook H4/H8 - Commercial and Government Entity (Cage) Code. Manufacturers that were not listed in the catalog when this listing was compiled have been assigned a unique five-letter code. This code is assigned arbitrarily and has no other significance. The manufacturers identified for parts that have JAN or MIL part numbers are Nautel's normal supply source for that part.

NOTE OEM code 37338 is listed for parts manufactured by Nautel or to a Nautel control drawing.

V1 REPAIR MANUAL Section 5 WIRING INFORMATION

5.1 INTRODUCTION This section contains wiring information for hard-wired assemblies of the subject unit. Refer to Table 5-1 for an itemized listing of assemblies that have wiring lists. 5.2 WIRING LISTS NOT PROVIDED Separate wiring lists are not provided for some assemblies, including: • Assemblies that have separate

maintenance manuals. Refer to the associated maintenance manual for detailed wiring information of these assemblies.

• Assemblies that have their wiring

information adequately depicted/ tabulated on their assembly detail drawings. Refer to the associated assembly detail drawing for detailed wiring information of these assemblies.

5.3 PRINTED WIRING PATTERNS Printed wiring pattern information is beyond the scope of this manual. Therefore, detailed printed wiring patterns for printed circuit boards are not included. 5.4 WIRE COLOURS Every effort is made to manufacture the assemblies using wire that is the colour tabulated in the ‘Code’ column of the wiring list tables. In some instances, a white wire will be substituted. In this case identification must be determined by locating the assigned identification number. 5.5 WIRING LIST PROVIDED Wiring lists are provided in table format. A list of the table numbers and the associated wiring list are shown in Table 5-1. These lists provide non-printed wiring pattern, point-to-point (source/destination) inter-connecting information.

V1 REPAIR MANUAL Section 6 ELECTRICAL SCHEMATICS

6.1 INTRODUCTION This section contains electrical schematics/ logic diagrams for the subject equipment. Block diagrams, simplified electrical schematics, and/or logic diagrams may be included. Refer to Table 6-1 for an itemized listing. 6.2 COMPONENT VALUES Unless otherwise specified on the logic/ schematic diagram, the following applies: • Resistor values are shown in ohms.

(K = 1000 and M = 1 000 000). • Resistor power ratings are not shown

when less than 0.5 W. • Capacitor values are shown in

microfarads (uF). • Unidentified diodes are part number

1N4938. 6.3 GRAPHIC SYMBOLS The graphic symbols used on electrical schematics are in accordance with American National Standard ANSI Y32.2-1975 - Graphic Symbols for Electrical and Electronic Diagrams. 6.4 LOGIC SYMBOLS The logic symbols used on electrical schematics and logic diagrams are in accordance with American National Standard ANSI Y32.14-1975 - Graphic Symbols for Logic Diagrams. 6.5 REFERENCE DESIGNATIONS Reference designations were assigned in accordance with American National Standard ANSI Y32.16-1975 - Reference Designations for Electrical and Electronic Parts and Equipment. Each electrical symbol is identified with its basic reference designation. To obtain the full reference designation for a specific part, this basic identifier must be

prefixed with the reference designation assigned to all higher assemblies. 6.6 UNIQUE SYMBOLOGY Nautel utilizes unique symbology on electrical schematics to describe two-state (logic) inputs/outputs that differ from those inputs/ outputs having only one distinct state or multiple states (analog). 6.6.1 Type of Inputs/Outputs On electrical schematics, names used to describe two-state (logic) inputs/outputs are prefixed by a '#'. Those inputs/outputs representing a one-state or analog signal will have no prefix. 6.6.2 Logic Level/Convention The '#' prefix identifies an input/output that has two distinct states - 'high' and 'low'. A suffix, '+' or '-', identifies the active (true) state of the input/output. The 'high' (+) is the more positive of the two levels used to represent the logic states. The 'low' (-) is the less positive of the two levels used to represent the logic states. Two types of logic, positive and negative, may be represented on a particular schematic. In positive logic, 'high' represents the active (true) state and 'low' represents the inactive (false) state. In negative logic, 'low' represents the active state and 'high' represents the inactive state. 6.7 IDENTIFICATION OF SCHEMATIC DIAGRAMS A number that is both the figure number and the page number identifies each illustration in this section. The numbers are assigned sequentially and are prefixed by the letters 'SD-'. The electrical schematics/logic diagrams included in this section are listed in Table 6-1.

2 V1 Repair Manual Issue 2.2 Section 6 Electrical Schematics

6.8 STRUCTURE OF SCHEMATICS The electrical schematics are structured in a hierarchical format that is based on function and signal flow. Wherever practical, the signal flow is from left to right. Inputs normally originate on the left-hand side and outputs will extend to the right-hand side. Exceptions are shown by an arrow indicating the direction of signal flow.

NOTE The physical location of a part/assembly was not necessarily a factor when a schematic was drawn. The full reference designation assigned to a part/ assembly, in conjunction with the family tree in Figure 4-1 and the assembly detail drawings in section 7, will identify its location. Figure SD-1 identifies the major stages. Each stage contains cross-references that identify which block is the signal source for inputs or the destination for outputs. When a sub-function is treated as a block, its detailed circuit information is included in its own schematic drawing(s), also included in this section. 6.9 LOCATING THE SCHEMATIC DIAGRAM(S) FOR A FUNCTIONAL BLOCK The text inside a functional block provides the key to locating its schematic diagram(s). When a functional block is assigned a reference designation, refer to the family tree depicted in Figure 4-1 and follow the family tree branches to the block that contains the reference designation and associated Nautel nomenclature (e.g., NAPC153/01). Refer to Table 6-1 with the Nautel nomenclature number and/or the description to identify the appropriate figure number(s).

6.10 LOCATING A PART/ASSEMBLY IDENTIFIED ON A SCHEMATIC The full reference designation assigned to a part/assembly is the key to physically locating that part/assembly.

NOTE Full reference designations contain the assembly hierarchical coding. When the end item is divided into units (cabinets), the first coding is a unit number (1, 2, 3, etc). When the end item is divided into assemblies, the first coding is an assembly number (A1, A2, A3, etc). If a unit or an assembly is divided into sub-assemblies, assembly coding that identifies assembly relationship (1A1, A2A1, A2A1A1, etc) is added. Refer to the family tree depicted in Figure 4-1 with the full reference designation and follow the family tree branches to the appropriate block, noting the name and Nautel nomenclature number of all higher assemblies in the path.

NOTE The drawings in Section 7 depict the assembly detail of the transmitter and its modules/assemblies. Refer to Table 7-1 with the name and Nautel nomenclature number of each family tree block in the path, starting at the highest assembly (normally Figure MD-1) and determine the figure number(s) for that assembly. Refer to the referenced figure and locate the next lower level assembly. Repeat this procedure until the location of the required part/assembly is found.

V1 REPAIR MANUAL Section 7 MECHANICAL DRAWINGS

7.1 INTRODUCTION This section contains mechanical drawings for assemblies of the subject equipment. Dimensional drawings may be included. Refer to Table 7-1 for an itemized list. Assembly detail drawings for assemblies/ modules that have separate maintenance manuals are not included. Refer to the appropriate maintenance manual for the assembly detail of these assemblies. 7.2 LOCATING ASSEMBLY DETAIL DRAWINGS Each illustration in this section is identified by a number that is both the figure number and the page number. The numbers are assigned sequentially and are prefixed by the letters 'MD-'. Drawings in this section are listed in Table 7-1.

7.3 CONTENT OF MECHANICAL DRAWINGS Mechanical drawings are illustrations that depict the location of electrical components and show assembly outline detail. Dimensional information is included, where appropriate. When a module/assembly is the subject of its own assembly detail drawing and it is also shown in a higher level assembly, the detail depicted in the higher level assembly may have minor differences from the module/ assembly actually installed. In this case, always refer to the assembly detail drawing of the module/assembly for detailed information.
