Artificial Respiration (Mouth-to-Mouth)

(a) START MOUTH-TO-MOUTH BREATHING IMMEDIATELY. SECONDS COUNT. Do not wait to loosen clothing, warm the casualty, or

apply stimulants. (b) ASSESS RESPONSIVENESS OF CASUALTY. Do not jar casualty or

cause further physical injury (Figure 1) (c) IF POSSIBLE, SEND A BYSTANDER TO GET MEDICAL HELP. Do

not leave casualty unattended (Figure 2)

(d) CHECK CAROTID PULSE (Figure 3) (e) LAY CASUALTY ON HIS/HER BACK and place any available jacket

or blanket under his/her shoulders. (f) TILT THE HEAD BACK AND LIFT THE CHIN to open the airway

(Figure 4)

(g) PINCH CASUALTY’S NOSE AND EXHALE TWO SLOW BREATHS INTO CASUALTY (Figure 5)

(h) REMOVE YOUR MOUTH and check for breathing (Figure 6) (i) CONTINUE GIVING ONE BREATH EVERY FIVE SECONDS without

interruption. If any air is retained in the stomach after exhalation by casualty, press gently on stomach to expel air.

(j) IF CHEST DOES NOT RISE, CHECK for obstruction in casualty’s mouth: clear foreign material using your finger, tissues, etc. Use chin lift and recommence mouth-to-mouth breathing.

(k) WHILE MOUTH-TO-MOUTH BREATHING IS CONTINUED have someone else:

- Loosen casualty’s clothing.

- Keep the casualty warm. (l) DON’T GIVE UP. Continue without interruption until the casualty is

revived, or until a doctor pronounces the casualty dead. Four hours or more may be required.

(m) DO NOT PROVIDE ANYTHING ORALLY while victim is unconscious.

V10/V7.5/V5/V3.5 Installation and Operation Manual Jul.05.07

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. Danger of infection when 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; care must be taken to cover and not to break the blisters.

11. If severe bleeding of wound, 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.

V10/V7.5/V5/V3.5 Installation and Operation Manual Jul.05.07

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, it can 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, if breathing has stopped, artificial respiration should be commenced immediately. If the carotid pulse cannot be felt, external cardiac massage should be commenced simultaneously. Resuscitation should be continued 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 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.

Section 2 PREPARATION FOR USE AND INSTALLATION

2.1 INTRODUCTION

This section contains pre-installation and installation information for the transmitter.

NOTE

Failure to comply with instructions in this section may void the manufacturer’s warranty. Please review Nautel’s warranty terms for more information.

2.2 PREPARATION FOR USE

Prepare the site to receive the transmitter prior to its delivery and/or installation. Consider the following when preparing new sites and use it as the evaluating criteria at existing sites. Nautel recommends that you incorporate all requirements to ensure optimum reliability and performance.

NOTE

Frequent reference is made to connectors and terminal blocks on the remote interface PWB. This PWB is located at the front of the transmitter behind the silkscreened front panel.

2.2.1 Transmitter Room Requirements

Address the following criteria when finalizing the transmitter site.

2.2.1.1 Transmitter Dimensions

Refer to Figure 2-8 (V10/V7.5) or 2-9 (V5/V3.5) for transmitter dimensions. Dimensions identify room entry and floor space requirements and will assist in determining cable lengths and routing.

2.2.1.2 Transmitter Weight

Refer to Figure 2-1 for transmitter weight. Sufficient manpower or lifting apparatus is required to move the transmitter.

2.2.1.3 Transmitter Clearances

Refer to Figure 2-1 for recommended transmitter clearances, noting that the V10/V7.5 cabinet is larger than the V5/V3.5 cabinet.

2.2.1.4 Air Flushing

Fans at the rear of each RF power module and at the front of each switching power supply module draw cooling air through a filter in the rear of the transmitter. Cooling air exhausts through openings in the front and top of the transmitter.

Open Ventilation: modules exhausts at the top front and air from the switching power supply modules exhausts at the bottom of the front door. An air exchange rate of 1007 CFM (V10), 864 CFM (V7.5), 490 CFM (V5) or 431 CFM (V3.5) achieves acceptable intake/ exhaust temperature rise.

Closed Ventilation: the transmitter by first entering via the top of an extension rack at the rear, then exhausting through the top of an extension rack at the front. The static pressure in the exhaust duct must be slightly negative. The static pressure at the rear of the transmitter must be neutral or slightly positive.

2.2.1.5 Cooling and Heating

Refer to Figure 2-1 for transmitter room ambient air temperature limitations. Refer to Table 2-1 for cooling requirements. Ensure adequate cooling and/or heating systems are in place to maintain appropriate ambient air temperature.

2.2.1.6 Work Area

Nautel recommends that a suitable work area with an adequate table surface be provided near the transmitter to permit bench adjustment and repair of modules. Static precautions must be observed.

2.2.1.7 Ac Power Switch

An ac power switching assembly should be wall mounted in close proximity to the transmitter.

2.2.2 Lightning Protection

Extremely high voltage and current transients are produced when a lightning strike occurs. These transients, which are usually the most significant hazard to any solid state transmitter, may be passed to the transmitter through the wiring connecting the transmitter to the power source and the antenna system. All practical precautions should be taken to protect the transmitter from this phenomenon. Refer to the Lightning

Protection section of Nautel’s Recommendations for Transmitter Site Preparation booklet for specific protection

techniques. Installing Nautel’s surge protection panel is highly recommended. The following requirements are considered to be essential and failure to follow the site layout requirements may void the transmitter warranty.

Page 2-2 V10/V7.5/V5/V3.5 Installation and Operation Manual Issue 3.5 Section 2 Preparation for Use and Installation

2.2.3 Station Reference Ground

The site must contain a station reference ground, as defined in Nautel’s

Recommendations for Transmitter Site Preparation booklet. This ground must

provide a continuous, low impedance path to the earth. The transmitter cabinet's designated reference ground point, the shield of the coaxial feed cable, and the ground connection of the power source's surge protection devices must be connected directly to the station reference ground using, as a minimum, 100 mm (4 inch) copper strap.

2.2.4 Ac Power Source

All conductors from the ac power source should be protected by bi-directional surge protection devices that are connected between each conductor and the station reference ground. In addition, the conductors, as a group, should pass through a ferrite toroid. The inductance formed by this toroid is transparent to the ac voltages, but presents impedance to transients originating in the power source. Four toroids (Nautel Part # LP23) are provided in the ancillary kit. A surge protector panel, containing suitably rated varistors, is available from Nautel for this purpose. If used, the surge protector panel should be installed in close proximity to the station reference ground.

NOTE

The following paragraphs discuss customer required connections to the transmitter. Figure 2-2 is provided as an aid for various customer interface connections and should be referenced while planning and installing these connections.

2.2.4.1 Ac Wiring

For most applications, Nautel recommends using 2 AWG ac wiring (for 1-phase V10s, Nautel recommends using 1 AWG). If smaller wiring is preferred, refer to Table 2-2 to determine the maximum phase current and suggested wire size for your transmitter. Consider all possible modes of operation.

NOTE

Observe local electrical codes when sizing cables. The ac power source usually presents the lowest impedance path to ground potential for a lightning strike and will normally carry most of the lightning induced current away from the transmitter site. When lightning hits the power source, a significant amount of induced current may flow towards the transmitter. Current should be routed around the transmitter, instead of through it, to the best ground available.

2.2.5 Antenna Feed Cable

The shield of the antenna feed coaxial cable should be connected directly to the station reference ground where it enters the building. In addition, the centre conductor and the shield of the feed cable should pass through a ferrite toroid that is between the shield ground at the building entrance and the shield termination at the transmitter reference ground. This toroid is transparent to the RF signal, but presents impedance to transients originating at the antenna. The transmitter ancillary kit includes four 85.7 mm diameter toroids (Nautel Part # LP23).

2.2.6 Antenna/RF Output Disconnect

Incorporate a switching circuit into the RF feed/antenna design, which disconnects the antenna from the transmitter's RF output when the transmitter is turned off. This switching circuit will prevent lightninginduced transients from damaging the transmitter’s solid-state devices.

2.2.7 Antenna Tower

The antenna tower is the most likely target for lightning strikes. It is imperative that it contains lightning protection devices as the first line of defense against lightning strikes.

2.2.8 External Control/Monitor Wiring

All external control/monitoring wiring that may be subject to lightning induced transients, should be interfaced to the station reference ground by surge protection devices at the point of building entry. All conductors and their shields should pass through a ferrite toroid that is positioned between its surge protection device and the transmitter. This toroid is transparent to control/monitor signals, but presents impedance to lightning induced transients. There are three toroids installed above the remote interface PWB (see Figure 2-2). The transmitter ancillary kit also includes four 38 mm diameter toroids (Nautel Part # LXP38).

2.2.9 Electrical Power

The transmitter is factory configured to operate from a 50/60 Hz, three-phase ac power source between 180 and 264 V ac or between 312 and 457 V ac or from a 50/60 Hz, single-phase ac power source between 180 and 264 V ac. The ac power source and associated switching components and wiring must meet all of the following requirements:

2.2.9.1 Voltage Stability

The ac power source’s nominal voltage must be maintained within the specified voltage range under all loading conditions. The transmitter contains circuitry that maintains the RF output at the pre-set carrier level for voltage variations within this range.

2.2.9.2 Power Consumption

Power consumption varies depending on the transmitter’s mode of operation (analog/hybrid/all-digital). If the transmitter configuration is a dedicated analog, hybrid, or all-digital transmitter, use Table 2-2 to determine the actual input power requirements. If the transmitter configuration is variable (between all modes), use the analog (FM mode) power source capacity information. Nautel recommends using the highest current values (FM mode) when determining wire ratings.

Nautel recommends the ac power source have a 25% over-capacity to ensure adequate regulation.

2.2.9.3 External Ac Switching

All current carrying conductors from the ac power source must be controlled by an external switching box located in close proximity to the transmitter. This switch box should be clearly marked

TRANSMITTER EMERGENCY ON/OFF SWITCH. See Table 2-2 for current ratings

and suggestions that should aid in selecting a circuit breaker and associated input wiring.

2.2.10 Antenna System

The antenna system must present 50 ± j0 Ω impedance at the carrier frequency. The transmitter will function while operating into a maximum VSWR of

1.5:1, but overall system performance will be degraded. Circuitry within the transmitter will prevent damage to the transmitter from high VSWR loads.

2.2.10.1 RF Feed Cable

The RF feed cable interconnecting the transmitter and the antenna system should be a suitably rated coaxial cable. As a standard, the RF output is configured to accept a non-gas type 3-1/8 inch (V10/V7.5) or 1-5/8 inch (V5/V3.5) EIA flange (male) connection (appropriate male inner connector not provided with

the transmitter). Optional EIA connections are available (see below):

V10/V7.5: 7/8 or 1-5/8 inch also available V5/V3.5: 7/8 or 3-1/8 inch also available

2.2.11 RF Drive Source(s)

The RF drive source type and power level depends on the transmitter’s operational mode (all-digital/hybrid/analog).

An exciter (or dual exciters) provides an IBOC (phase modulated OFDM) signal and/or an FM carrier in the 87.5 to 108 MHz band.

The exciter’s output power should be 20 W (10 W) for analog configured V10/V7.5 (V5/V3.5) transmitters or 10 W (5 W) for digitally configured V10/V7.5 (V5/V3.5) transmitters operating in analog mode.

The transmitter cabinet accepts one or two Nautel FM exciters. Each exciter must have an external on/off interlock or RF mute capability. The transmitter provides a set of form C contacts on the remote interface PWB (A44) for each exciter’s RF mute control. Exciter A’s contacts are between TB2-1 and TB2-3 (N/C) or TB2-2 and TB2-3 (N/O). Exciter B’s contacts are between TB2-4 and TB2-6 (N/C) or TB2-5 and TB2-6 (N/O). If the exciter needs an open on its interlock terminals to not be muted, connect to N/O (normal operation is open). If the exciter needs a short on its interlock terminals to not be muted, connect to N/C (normal operation is closed).

2.2.11.1 Digital (IBOC) Operation

For IBOC operation, the exciter uses Exgine technology. An exporter provides the digital component directly to the exciter via an Ethernet connection; the transmitter requires no additional connection.

Page 2-8 V10/V7.5/V5/V3.5 Installation and Operation Manual Issue 3.5 Section 2 Preparation for Use and Installation

2.2.12 External Interlocks

The external electrical interlock circuit is connected between XMTR INTLK terminals TB1-1 and TB1-2 of the remote interface PWB (A44). It must present a short circuit (low impedance) between the terminals when the interlock circuit is intact and it is safe to enable the RF output. It must present an open circuit when any interlock switch is activated and the RF output requires inhibition. Any number of serial interlock switches may be installed.

2.2.13 Remote Control Circuits

The transmitter control/monitoring functions can be facilitated by means of a conventional remote control interface or serial port (using the NxLink module), all available via connection to the remote

The switching circuit for each remotely controlled function must be the equivalent of a normally open/held closed, springloaded (momentary) switch. Each must be configured to operate as a single ended input using the transmitter's regulated 15 V as the dc volts source (see Figure 2-4), or as a differential input using an external dc power supply (5 V to 30 V) as the dc volts source (see Figure 2-5). Each control function has positive and negative input terminals on the remote interface PWB to accommodate the selected configuration.

interface PWB (A44). See paragraph

2.2.14 for a description of the serial port features. Remote control inputs are polled (sampled) every 100 ms. Ensure the active pulse duration is a minimum of 100 ms. The on/off status, active (A/B) exciter/ IPA/IPA PS/Fan PS, active power preset (1-6), RF power level, and system reset can be controlled remotely by switching circuits.

NOTE

Unless noted, all remote interfacing is done via the remote interface PWB (A44). External control circuits are interfaced to the transmitter through opto-couplers on the remote interface PWB. The optocouplers buffer/isolate the external circuits and prevent unwanted transients from affecting transmitter operation. These opto-couplers only have influence when Remote control is selected. All external input/output interface connections are shown in Figure 2-7a (V10/V7.5) or 2-7b (V5/V3.5). The remote interface PWB contains circuits that allow the user to

Single Ended Input (Internal V dc)

When the transmitter's regulated +15 V is used as the current source for a control function's opto-coupler, its circuit on the remote interface PWB must be configured for a single ended input. The 3-pin header associated with the control function must have its 2-socket shunt post connected as depicted in Figure 2-4, noting pins 2 and 3 of the header are shorted by the shunt post. A negative logic command (active state is a current-sink-to-ground) must be applied to the control's negative (-) input pin. The active command should be of sufficient duration (minimum 100 ms) to ensure being sampled. See Table 2-3 or Figure 2-7a (V10/V7.5) or 2-7b (V5/V3.5) for dc return (ground) locations.

When an external dc voltage (5 - 30 V) is used as the current source for a control function’s opto-coupler, the control function's external switching circuit and the remote interface PWBs selection circuitry must be configured for differential input. The 3-pin header associated with the control function must have its 2-socket shunt post connected as depicted in Figure 2-5, noting pins 1 and 2 of the header are shorted by the shunt post. The normally open/held closed switch may be located between the dc voltage's negative output and the negative (-) input pin (negative logic) or between its positive output and the positive (+) input pin (positive logic). The active command should be of sufficient duration (minimum 100 ms) to ensure being sampled.

For V10/V7.5 transmitters, this circuit simultaneously selects the main IPA module and its associated IPA power supply. For V5/V3.5 transmitters, a separate remote control is available to select the main IPA power supply (see

2.2.13.4).

NOTE

For V10/V7.5 transmitters, the remote selection of the active IPA module is ganged together with the remote selection of the active IPA power supply.

For V5/V3.5 transmitters, the remote selection of the active IPA PA is independent from the remote selection of the active IPA power supply.

2.2.13.4 Main IPA Power Supply Selection

(For V5/V3.5 transmitters only) The main IPA power supply selection circuit selects which IPA power supply is enabled as the main IPA power supply. It comprises an A (J6-27/28) and a B (J6-29/30) circuit. This function is ganged together with the main IPA selection (2.2.13.3).

2.2.13.5 Main Fan Supply Selection

The main fan supply selection circuit selects which fan supply is enabled as the main fan supply. It comprises an A (J4-29/30) and a B (J4-31/32) circuit.

2.2.13.6 Preset Power Level Selection

The power level selection circuit selects one of six preset RF power levels/modes. It has six switching circuits [Preset 1 (J4-2/3), Preset 2 (J4-4/5), Preset 3 (J4-6/7), Preset 4 (J4-8/9), Preset 5 (J4-10/11) and Preset 6 (J4-12/13)].

2.2.13.7 Power Level Adjust

The power level adjust circuit controls the RF output level in an increasing or decreasing direction when the appropriate input is applied and removed. The circuit comprises an increase (TB4-7/8) and a decrease (TB4-9/10) circuit. The size of the change depends on the operating mode and the duration of application time.

In analog (FM) mode, a temporary (pulse) application causes a 100 W (V10/V7.5) or 50 W (V5/V3.5) change. A three-second or longer application causes a 1,000 W (V10/V7.5) or 500 W (V5/V3.5) change.

In hybrid (FM+HD) or all-digital (HD) mode, a temporary (pulse) application causes a 1% change based on the transmitter’s rated power level [for FM+HD mode, 75 W (V10), 55 W (V7.5), 37 W (V5) or 27 W (V3.5); for HD mode, 30 W (V10), 20 W (V7.5), 15 W (V5) or 10 W (V3.5)].

A three-second or longer application causes a 10% change [for FM+HD mode, 750 W (V10), 550 W (V7.5), 370 W (V5) or 270 W (V3.5); for HD mode, 300 W (V10), 200 W (V7.5), 150 W (V5) or 100 W (V3.5)].

2.2.13.8 System Reset

The remote reset circuit (TB3-11/12) resets any alarm circuit that is or was latched in its alarm state.

2.2.14 Serial Port

The transmitter’s remote interface PWB (A44) has an RS232 serial interface port (9-pin D-sub connector J8) to allow remote control and interrogation of the transmitter’s operational status. A remote protocol specification is available from Nautel. The application must be written by the end user based on protocol.

NOTE

If the optional NxLink Ethernet interface module is used (see 2.2.21.10), A44J8 is linked to Port 1 of the NxLink module and the NxLink module is used as the remote interface.

2.2.15 RF Performance Monitoring

The transmitter provides outputs to monitor RF performance. They include dc voltages representative of the forward and reflected power levels, dc voltage applied to the RF amplifiers, exciter forward power, intake and exhaust air temperature and total PA current.

NOTE

The remote monitoring samples in 2.2.15.2 through 2.2.15.8 are op-amp buffered outputs from an analog-to-digital converter (ADC). The dc voltage of each output sample varies linearly with the parameter being monitored.

The maximum sample voltage is representative of the parameter’s full-scale value (e.g., 12,000 W for V10 forward power; 9,000 W for V7.5 forward power; 6,000 W for V5 forward power; 4,500 W for V3.5 forward power). This full-scale voltage can be scaled (between 0 and 5 V), using the front panel’s GUI, to suit a particular requirement. Each monitoring circuit’s

impedance must be greater than 1,000

There are also five user-configurable sample outputs (Sample Out 8 through Sample Out

12), which can be used to monitor any metered parameter on the GUI (see 3.6.11).

2.2.15.2 Forward Power Level Sample

(Sample Out 1) The dc voltage on TB1-20 is full-scale when the forward power is 12,000 W (V10), 9,000 W (V7.5), 6,000 W (V5) or 4,500 W (V3.5).

2.2.15.3 Reflected Power Level Sample

(Sample Out 2) The dc voltage on TB1-21 is full-scale when the reflected power is 1,200 W (V10), 900 W (V7.5), 600 W (V5) or 450 W (V3.5).

2.2.15.4 Power Amplifier Volts Sample

(Sample Out 3) The dc voltage on J6-9 is full-scale when the PA voltage is 60 V.

2.2.15.5 Exciter Forward Power Level Sample (Sample Out 4)

A switching device for each alarm output provides a current-sink-to-ground when an alarm occurs. The switching circuit provides an open collector during normal operation and has no influence on the external monitoring circuit. Each circuit must present impedance between the switching device and a dc voltage source that limits current to 50 mA. +15V is available at TB1-18 of the remote interface PWB. If an external dc power source is used, it must not exceed +24 V. Its return must be connected to a GND terminal [see Figure 2-7a (V10/V7.5) or 2-7b (V5/V3.5)] on the remote interface PWB. Unless otherwise noted, all remote interfacing is made to the remote interface PWB.

INSTALLATION AND OPERATION MANUAL

Section 3 OPERATING INSTRUCTIONS

3.1 INTRODUCTION

The following instructions are intended primarily for persons involved in testing or maintenance of the equipment.

3.1.1 Precautions

The transmitter contains many solid state devices that can be damaged if they are subjected to excessive heat or high voltage transients. Ensure the circuits are not overdriven and are not disconnected from their loads while turned on.

3.2 EMERGENCY SHUTDOWN

If an emergency shutdown is necessary, special precautions are required. However, the type of shutdown is dictated by the reason for the shutdown. There are two types of shutdown. The first turns off the RF output and disables all of the internal power supplies by disconnecting the ac power source. The second turns off the RF output by inhibiting the power output stages.

3.2.1 Complete Shutdown

When the cause of the emergency shutdown dictates the need for a complete shutdown of the transmitter, do the following:

• Switch off the ac power source at the ac power entrance.

3.2.2 Turn Off RF Output

When the cause of the emergency shutdown is external to the transmitter or is in the RF output portion of the transmitter, the following will turn off the RF power produced by the power modules:

The following will not remove the ac power source voltage from the transmitter or inhibit any of the internal low voltage dc supplies. If the reason for the shutdown requires all voltages be turned off, proceed directly to paragraph

3.2.1

• If in local or remote control, press the

Control - RF Off switch on the transmitter’s front panel.

• If in remote control, select RF Off at the remote control site.

• Open any external interlock switch.

3.3 EXTERNAL SAFETY INTERLOCK

The external electrical interlock circuit is a protection circuit controlled by user determined, serially connected, normally open/held closed interlock switches. It inhibits the RF output when it is not safe to produce RF output.

When all of the external interlock switches are closed and it is safe to produce an RF output, the front panel's system diagram External Alarm lamp will be off. The operator will have full control of transmitter functions.

When any external interlock switch is open, the RF output stages will automatically turn off. The front panel's system diagram External Alarm lamp will turn on (alarm state). It is not possible to enable the RF power stages until all of the external interlock switches are closed.

WARNING

V10/V7.5/V5/V3.5 Installation and Operation Manual Page 3-1

Section 3 Operating Instructions Issue 3.5

3.4 ELECTROSTATIC DISCHARGE PROTECTION

The transmitter's assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge (ESD). Observe the following precautions 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.

3.4.1 Discharging of Personnel

Maintainers must be electrically discharged by a suitable ground system (anti-static mats, grounding straps) when removing an assembly from the transmitter and while handling the assembly for maintenance procedures.

3.4.2 Handling/Storage

Place the assembly in an anti-static bag when it is not installed in a host transmitter or when it is not being subjected to maintenance procedures. Electronic components should be stored in anti-static materials.

3.4.3 Tools/Test Equipment

Testing and maintenance equipment, including soldering and unsoldering tools, should be suitable for contact with static sensitive semiconductor devices.

3.4.4 Stress Current Protection

Always 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.

3.5 CONTROLS AND INDICATORS

Nautel recommends the operator/maintainer be familiar with the transmitter's controls and indicators before operating the transmitter and/or attempting to perform fault diagnostics. In most cases, controls and indicators are presented in an assembly-by-assembly format. A mechanical drawing and an associated table are provided as aids to locating and understanding the assembly’s controls and indicators.

NOTE

On some mechanical drawings, numbered callouts are provided to cross-reference the control/indicator to the description table.

The names used in the PANEL MARKING column of the controls and indicators tables are intended to be the closest possible representation to the item’s label/silkscreen.

Page 3-2 V10/V7.5/V5/V3.5 Installation and Operation Manual Issue 3.5 Section 3 Operating Instructions

3.5.1 Front Panel

The front panel is the primary local user interface for the transmitter. Control and indicators are grouped into four sections of the panel (see Figure 3-1) as follows:

• System Diagram

- a simple block diagram of the transmitter complete with alarm lamps. Refer to Figure 3-2 and Table 3-1 for a description of the controls and indicators.

• Control

– push-button switches that allow convenient control of the transmitter’s RF status (on or off and increase or decrease) and its operator control source (local or remote). The RF Off switch is functional regardless of local or remote selection. Refer to Figure 3-3 and Table 3-2 for a description of the controls and indicators.

• Diagnostic Display

– a menu-driven user interface screen - with five associated push-buttons - which allows control and monitoring of the transmitter’s critical parameters and modes of operation. See paragraph 3.6 for a full description of the diagnostic display.

• Power Meter

– the RF KILOWATTS meter displays forward power on the upper scale and reflected power on the lower scale. Scale selection and meter enabling is selected using the diagnostic display (see paragraph 3.6.10).

External Alarm

When turned on (red), typically indicates the active exciter’s (A14 or A15) RF output to the active IPA module is above or below the preset range, OR communication between the transmitter and exciter (M50 only) has failed, assuming a serial link exists OR an audio loss has occurred in the exciter. This alarm will initiate a changeover in dual exciter transmitters; the exciter designated as standby will be operating as the active exciter.

When turned on (red), indicates one (single) or both (dual) LVPS modules (U11 or U12) or fan supply modules (U13 or U14) has failed. This alarm will initiate a changeover in dual fan power supply transmitters; the fan power supply module designated as standby will be operating as the active module.

When turned on (red), indicates the ac voltage applied to the transmitter, is below an acceptable level. Transmitter will shut down.

When turned on (red), indicates a fault has occurred in one or more of the switching power supply modules that supply the IPA and RF power modules. Depending on the options installed, the transmitter may initiate a changeover to the standby IPA power supply module or operate at a reduced power level or be shut down. May also indicate that the backup battery’s voltage is below an acceptable threshold.

When turned on (red), indicates the external interlock circuit is not presenting a closed circuit. Transmitter will be shut down.

Changeover

When turned on (red), indicates a changeover to the standby exciter/IPA/IPA PS/fan PS module (as applicable) has been enabled due to a fault in the main exciter/IPA/IPA PS/fan PS module.

IPA/PA

When turned on (red), indicates a fault has occurred in one of the IPA or RF power modules. In the case of an IPA module fault, a changeover will be initiated (for dual IPA transmitters); the IPA designated as standby will be operating as the active IPA. In the case of an RF power module fault, the transmitter will continue to operate at a reduced power level.

Output Network

When turned on (red), indicates the transmitter’s RF power is being cut back or shut back due to an impedance mismatch (high VSWR) at the transmitter’s output OR the forward power level has exceeded an acceptable level (while ALC is disabled) OR the forward power has been decreased below 1630 W (V10)/1223 W (V7.5)/815 W (V5)/ 612 W (V3.5) (due to SWR foldback) OR one of the combiner’s cooling fans has failed OR the power level or temperature in one of the hybrid combiner’s reject loads has exceeded an acceptable level.

NOTE

In each case, root-cause details of the fault are displayed in the

diagnostic display’s Events Log (see paragraph 3.6.6)

DESCRIPTION

SGL/DIFF Input

Selection

E1 through E21

Bi-position selection jumpers that configure the remote interface PWB to accept either single-ended (SGL) or differential (DIFF) remote control inputs. A differential input is selected when a shorting shunt post (E1 through E21) shorts pins 1 and 2 of its associated 3-pin header. A single-ended input is selected when a shorting shunt post (E1 through E21) shorts pins 2 and 3 of its associated 3-pin header.

See Table 2-3 for specific jumper settings. Note that some jumpers are installed as part of spare circuitry (E5 and E19) and do not require configuration.

DESCRIPTION

BIAS/DUAL IPA

Bi-position selection jumper that can be used to configure an RF power module for use as an IPA module in dual PA IPA V5/V3.5 transmitters only.

This jumper is factory set in the BIAS position (shorting pins 1 and 2) and requires no adjustment in a V10/V7.5 transmitter.

The jumper is factory set in the DUAL IPA position (shorting pins 2 and

3) for a dual PA IPA module in a V5/V3.5 transmitter.

If an RF power module is being used as a dual PA IPA module in a V5/V3.5 transmitter (as described in 5.11.2), the jumper should be set to DUAL IPA (shorting pins 2 and 3).

3.6 DIAGNOSTIC DISPLAY

The diagnostic display or GUI (Figure 3-9), in the centre of the transmitter’s front panel, is a 240 x 64 graphic LCD display that is the primary local user interface for the transmitter. Except for RF on/off and local/ remote control, this display can control and indicate all transmitter functions. The display monitors all critical parameters and events. The following paragraphs describe how to use the diagnostic display.

Edit/Save

Values can only be changed in a given menu by first pressing Edit. Changes can only become active by pressing Save. This prevents unintentional changes.

3.6.1 Pushbutton Switches

See Figure 3-1. Five push button switches next to the GUI allow for GUI navigation. The up (f) and down (g) push buttons, to the right of the GUI, are used to move up and down through displayed selections and to increase or decrease the value of a selected parameter. Holding the f or g push button increases the rate of change, where applicable. There are three  softkey push buttons whose functions are indicated by the text displayed directly above them for a given menu.

3.6.2 Main Screens

The high level screens of the diagnostic display (Figures 3-9 and 3-10) display:

• Transmitter status bar

• Three user-defined meter selections

• Meter selection scroll (controlled by f

and g pushbuttons)

• Sub-menu selections

3.6.2.1 Transmitter Status Bar

The transmitter status bar is the information shown at the top of the GUI. This information is present at all times and indicates the following (from left to right):

• Current time (24-hour clock)

INSTALLATION AND OPERATION MANUAL

Section 4 TESTING AND ADJUSTMENT

4.1 INTRODUCTION

This section contains step-by-step functional test procedures, using integral meters and precision test/monitoring equipment. The test procedures contain routine adjustment instructions to bring the parameter being tested within defined limits, where appropriate.

NOTE

Personnel who are not familiar with detailed circuit theory or do not realize the impact a specific adjustment will have on other steps should follow the instructions in the order they are presented. These adjustments should be performed during initial turn-on and after major repairs or a frequency change.

4.2 OPERATING PRECAUTIONS

The transmitter contains protection circuits that monitor critical parameters. When the defined limits of any of these parameters are exceeded, one or more of the transmitter’s front panel System Diagram lamps will turn on (red). When the alarm condition could result in excessive power amplifier stress current, the control voltage applied to the power amplifiers will effectively be reduced or turned off, as long as the cause of the out-of-tolerance condition exists. Maintainers should read and fully understand the Operating Instructions section, and in particular the controls and indicators section.

NOTE

The diagnostic display’s main screen displays three pre-determined parameters (e.g., forward power, PA voltage, total PA current, etc.). All transmitter parameters, in combinations of three, may be displayed on this screen. See paragraph 3.6.8.

4.3 FUNCTIONAL TESTS

Successful completion of the following tests will verify the transmitter circuits are within factory specifications. When a routine adjustment will correct an out-oftolerance condition, the adjustment procedure is included.

If an in-tolerance condition cannot be attained with the specified routine adjustment, discontinue testing until the problem causing the out-of-tolerance condition is corrected.

4.3.1 General

The functional tests should be performed as a routine part of scheduled maintenance checks and as the first step in troubleshooting procedures. These results should be recorded for comparison with past and future test results.

The functional test procedures are provided in a step-by-step format. This method of presentation permits a person who is unfamiliar with the transmitter to perform the functional tests in a logical sequence. Nautel recommends the procedures be completed in sequence, as each procedure establishes switch settings and contains prerequisites for subsequent procedures.

The following assume the initial turn-on procedure detailed in Section 2 has been completed during initial installation or after major repairs that warrant repeating the initial start-up procedure.

NOTE

into a precision, 50 Ω, resistive, dummy load that is able to accurately display the RF power applied to it.

WARNING

If a jumper is placed between the interlock inputs (TB1-1 and TB1-2) on remote interface PWB A44, safety features provided by the external interlocks will be disabled. A fail-safe method of alerting personnel to this fact should be implemented. Voltages dangerous to life are present on RF output stages and the antenna system when the transmitter is turned on.

(d) Close all external interlocks or connect

a temporary

jumper wire between TB1-1 and TB1-2 of the remote interface PWB.

NOTE

Remote interface PWB A44 is the uppermost PWB on the panel behind the silkscreened cover.

(e) Obtain the Proof of Performance test

results and the completed copy of the Critical Parameters sheet, taped to the tray in front of IPA module A (A19). For future reference, store these documents with section 5 of this manual or in the Repair Manual’s binder.

NOTE

The data in the Critical Parameters sheet is compiled at the factory with the transmitter

terminated in a precision 50

dummy load. Measurements made on site into a dummy load or the station antenna may not yield the same readings. Slight variances are acceptable. The data is provided as a routine maintenance and troubleshooting aid.

4.3.6.2 Exciter Auto Chan geov er Check (if applicable)

If the transmitter is configured for dual exciter operation, verify an exciter auto changeover is initiated when a main (active) exciter fault occurs as follows:

(a) Verify there are no existing alarms on

the control display panel and that the transmitter is operating at rated power.

(b) From the GUI’s changeover menu (see

3.6.13), set the Exciter Standby option to Y (yes).

exciter A (A14). A changeover to exciter B will occur. The exciter alarm will turn on momentarily (until the reserve exciter’s output power exceeds the IPA Input Low threshold), the system diagram Changeover alarm will turn on and the alarm will be noted on the GUI. The remote interface PWB’s CHGOV (changeover) ALARM (TB1-8) and IPA/RF Fail Alarm (J6-3) outputs should be an alarm condition (current-sink-to-ground). The remote interface PWB’s EXCTR STATUS output (TB1-15) will be a current-sinkto-ground.

(d) Reconnect the ac line cord to exciter A.

In the GUI’s changeover menu, set exciter B as the main exciter (see

3.6.13). The alarms should clear.

(e) Unplug the ac cord at the rear of

exciter B (A15). An exciter changeover to exciter A will occur. The exciter alarm will turn on momentarily, the Changeover alarm on the system diagram will turn on, and the exciter changeover alarm will be noted on the GUI. The remote interface PWB’s

CHGOV ALARM (TB1-8) and IPA/RF Fail Alarm (J6-3) outputs should be an

alarm condition (current-sink-toground). The remote interface PWB’s EXCTR STATUS output (TB1-15) will be an open-collector.

(f) Reconnect the ac line cord to exciter B.

In the GUI’s changeover menu, set exciter A as the main exciter (see
