Archimede 5000 series- FM Power Amplifiers

User’s manual –Page 5 of 65

1INTRODUCTION

Congratulations for your choice! Archimede High Power is a series of new-concept FM solid state (MOS-FET) amplifiers, available

in three different models according to their rated output power (Archimede 3000 3kW - Archimede 4000 4kW –Archimede

5000 5kW).

These systems are so compact they can be entirely fitted into a 19" 2 units rack 500 mm depth, making them the ideal solutions for

medium and high power repeaters in unattended stations, in N+1 systems and also as spare amplifiers. These are only some of the

state-of-the-art features that make the Archimede High Power series truly unique:

Ultra compact size and reduced weight. (Archimede 3000/4000:28kg, Archimede 5000:35kg).

Thoroughly modular construction. The R.F. amplifier is composed of ultra - compact new-generation internal modules (their

number depends on the model). Such modules can be easily identified and inspected.

High reliability. Thanks to the internal balance circuits, in case one of the internal modules fails, the other modules left are

automatically re-balanced, thus to continuing the operation at reduced power.

Better reliability. Per each model the rated output power is reached at nearly the 80% of the maximum output power the

equipment could generate.

Low operation costs. The special care taken in the design, aimed at minimizing internal losses, allows a very high electrical

efficiency to be achieved thus minimizing power consumption and thereby reducing operation costs.

High ventilation and low heat sinking. The reduced internal losses and high overall efficiency minimize heat sinking. As a

result, the size of the internal ventilation system can meet even the most demanding environmental conditions.

Large allowable bandwidth and low maintenance requirements.

Interactive control panel with LCD display. Enables the user to easily set the equipment modes and commands and to

display the operation parameters through the practical multifunction knob.

Sturdy modular mechanical and electrical construction. It guarantees a high MTBF and an easy maintenance.

High efficiency. To control the output power level the output power loop control adjusts first the power supply voltage of the

MOS FET and, if it’s not sufficient, it adjusts the Bias voltage.

Continuous control of the cooling fans speed. This control allows a constant temperature of the amplifier heatsink, and a

longer lifespan of the cooling fans.

Automatic reset when an active alarm ends. When an active alarm ends, the equipment is able to automatically reset itself,

without the need of human intervention.

Simple diagnostics and unambiguous parameters reading. This is due to a comprehensive metering and alarm section on

the control panel. Thanks to the optional external telemetry system, parameters and alarms are easily accessible from remote

posts through the relevant remote control input.

Compliance with the strictest norms. These equipments were designed in compliance with the tightest international norms,

as well as the recent, strict anti-magnetic noise EC requirements. Besides, the equipments comply with the EC and ETSI

302.018-2 v 1.1.2.1 (2006-03) standards.

Please note that the manufacturer, in his continuous attempt to improve further the quality of his product, reserves the right to

vary the technical features of the Falcon High Power models without prior notice.

Warning! Before carrying out any operation, it is essential to read the whole of the present manual –with particular

reference to Chapters 2 and 3 –in order to avoid damages to objects and people.

2GENERAL INFORMATION

2.1 Safety suggestions

Regardless of how well electrical equipment is designed, personnel can be exposed to dangerous electrical shock when

protective covers are removed for maintenance or other activities. Therefore, the user is obliged to see that all safety

regulations are consistently observed and that each individual assigned to the equipment has a clear understanding of the

first aid related to electrical shocks (see following pages).

IN ADDITION THESE SAFETY PRACTICES MUST BE FOLLOWED:

Do not attempt to adjust unprotected circuit controls or to dress leads with power on.

Always avoid placing parts of the body in series between ground and circuit points.

To avoid burns, do not touch heavily loaded or overheated components without precautions.

Remember that some semiconductor cases and solid-state circuits carry high voltages.

Do not assume that all dangers of electrical shock are removed when the power is off. Charged capacitors can retain

dangerous voltages for a long time after power is turned off. These capacitors should be discharged through a suitable resistor

before any circuit points are touched.

Don't take chances. Be fully trained. Italab ( ITB ) equipments should be operated and maintained by fully qualified personnel.

Do not service alone and do not perform internal adjustments of these units unless another person capable of rendering first

aid and resuscitation is present.

Some components used in the construction of this equipment contain Beryllium Oxide (BeO). This substance is harmless as it

is, but becomes highly dangerous if it’s ground to powder. Special procedures of disposal must be observed in case of failure of

these devices.

2.1.a General safety recommendations

When connecting the equipment to the power, please follow these important recommendations:

These products are intended to operate from a power source that will not apply more than 10% of the voltage specified on

technical specifications between the supply conductors or between either supply conductor and ground. A protective-ground

connection by way of the grounding conductor in the power cord is essential for safe operation.

According to the model, these units have to be grounded through the contact (GND) located on the rear panel or via the

grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired socket before

connecting to the product input or output terminals.

Upon loss of the protective-ground connection, all accessible conductive parts (including parts that may appear to be

insulating) can render an electric shock.

To avoid fire hazard, use only fuses of correct type, voltage rating, and current rating. Refer fuse replacement to qualified

service personnel.

To avoid explosion, do not operate this equipment in an explosive atmosphere.

To avoid personal injury, do not remove the product covers or panels. Do not operate the product without the covers and

panels properly installed.

Note: This section is not intended to contain a complete statement of all safety precautions which

should be observed by personnel in using this electronic equipment or others.

Italab Communications SHALL NOT BE responsible for injury or damage resulted from improper procedures

or from using it by improperly trained or inexperienced personnel.

2.1.b Good practices

In maintaining the equipment covered in this manual, please keep in mind the following, standard good practices:

When connecting any instrument (wattmeter, spectrum analyzer, etc.) to a high frequency output, use the appropriate

attenuator or dummy load to protect the final amplifiers and the instrument input.

When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off power from the affected

portion of the equipment. After power is removed, allow sufficient time for the power supplies to bleed down before reinserting

PCBs.

When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices may appear defective

because of leakage between traces or component leads on the printed circuit board. Clean the printed circuit board and

recheck the MOS device before assuming it’s defective.

When replacing MOS devices, follow standard practices to avoid damage caused by static charges and soldering.

When removing components from PCBs (particularly ICs), use care to avoid damaging PCB traces.

2.1.c First aid in case of electrical shock

If someone seems unable to free himself under electric shock contact, turn the power off before rendering aid. A muscular spasm or

unconsciousness can make a victim unable to free himself from the electrical power.

If power cannot be turned off immediately, very carefully loop a length of dry non-conducting material (such as a rope, insulating

material, or clothing) around the victim and pull him free of the power. Carefully avoid touching him or his clothing until free of power.

2.1.d Emergency resuscitation technique

Step 1

Check the victim for responsiveness. If there is no response, immediately call for

medical assistance, and then return to the person.

Step 2

Position the person flat on his back. Kneel by his side and place one hand on the

forehead and the other under the chin. Tilt the head back and lift the chin until teeth

almost touch. Look and listen for breathing.

Step 3

If not breathing normally, pinch the nose and cover the mouth with yours. Give two full

breaths. The person's chest will rise if you are giving enough air.

DO NOT TOUCH VICTIM OR HIS CLOTHING BEFORE POWER IS DISCONNECTED

OR YOU CAN BECOME A SHOCK VICTIM YOURSELF

Archimede 5000 series- FM Power Amplifiers

User’s manual –Page 8 of 65

Step 4

Put the fingertips of your hand on the Adam's apple, slide them into the groove next

to the windpipe. Feel for a pulse. If you cannot feel a pulse or are unsure, move on to

the next step.

Step 5

Position your hands in the center of the chest between the nipples. Place one hand

on top of the other.

Step 6

Push down firmly two inches. Push on chest 15 times.

CONTINUE WITH TWO BREATHS AND 15 PUMPS UNTIL HELP ARRIVES

2.1.e Treatment for burns

Continue treat victim for electrical shock.

Check for points of entry and exit of current.

Cover burned surface with a clean dressing.

Remove all clothing from the injured area, but cut around any clothing that adheres to the skin and leave it in place. Keep the

patient covered, except the injured part, since there is a tendency to chill.

Splint all fractures (violent muscle contractions caused by the electricity may result in fractures).

Never permit burned surfaces to be in contact with each other, such as: areas between the fingers or toes, the ears and the

side of the head, the undersurface of the arm and the chest wall, the folds of the groin, and similar places.

Transport to a medical facility.
