The original configuration of the equipment must absolutely not be modified. On receipt of the same equipment it is essential to check whether the supply is compliant with the orders specific terms and in case of nonconformities please report it immedi-

ately Elenos Srl.

Protective devices must not be disconnected (with exception of their replacement), altered or modified without authorization.

Check all protective devices periodically after the occurrence of a fault (e.g. devices against excess voltage, against excess currents, circuit breakers, etc.).

To guarantee safety of the personnel and to protect the equipment from damages it is absolutely forbidden to put it into operation and/or to use it while the doors are open and/or without the partial or whole presence of protection panels and/or without grounding connection, which must always be of extremely high quality and in accor-

dance with regulations in force. It is also forbidden to disconnect and/or to alter the equipments means of protection.

Before starting any operation, the equipment must be disconnected from the mains. Disconnection must be verified via visual inspection.

The equipment must be powered exclusively with the appropriate voltage. An incor-

rect power voltage can cause irreparable damages to the equipment and to the per-

sonnel working with it. This same information is reported on the products nameplate, which is generally located upon its casing. In no case must the name plate be removed, even if the equipment is resold.

The equipment must be powered by an electrical system which is compliant with the regulations in force.

On the equipment can be found further pictograms reporting safety warnings that must be carefully followed by anyone that has to work with it. The lack of respect for rules here described exempts the Constructor from all liability for all possible dam-

ages or accidents occurring to persons or property and place responsibility to the user himself. Hazardous voltage Safety 13 The equipment is directly connected to the building installation Between the equipment and the building connection there is an interposed structure

To ensure a correct use of the equipment do not obstruct the ventilation grids. Do not put the equipment close to heat sources, flammable products, or inside closed installations lacking of a proper air circulation.

It is required to observe general and firefighting rules for the place hosting the equip-

ment.

Avoid any liquid contamination to the equipment. Always disconnect power supply to the equipment before carrying out any cleansing operations. Do not use liquid or spray detergents.

Some components contain TOXIC SUBSTANCES, such as for example BERYL-

LUM OXIDE. Please be aware that in some countries rules for storing and disposing of hazardous materials may apply.

Following a visual check, if any component seems damaged, fractured or not intact, the utmost care must be taken when coming in physical contact through hands or other means with the equipment.

Please ensure that any person in charge of the use or the maintenance of a trans-

mitter presenting one or more parts under hazardous voltage is able to perform arti-

ficial respiration and cardiac massage; all the staff must be trained on how to pro-

vide first medical aid in case of emergency. It is strongly advised to hang in a visible position an informative panel reporting clear instructions regarding first aids proce-

dures for the rescue of people injured in a work accident and to supply rooms where electrical equipment is present with first aid kits. It is strongly advised to organize an intervention plan in order to ensure a quick connection with local public or private first aid institutions so to be easily available for all the people hosted within the site. 14 Safety 2.2 First aid This paragraph does NOT represent a complete guide about first aid procedures, it is rather intended as a brief summary to be used as a reference. It must be in fact an impel-

ling duty for all the personnel operating with this equipment to be capable of performing appropriate first aid procedures in order to prevent avoidable deaths. 2.2.1 Treatment of electrical burns 2.2.1.1 Extensive burns and skin cuts

Cover the area with a clean sheet or cloth.

Do not break blisters, not remove tissue, not remove adhered particles of clothing, or apply any ointment.

Treat the victim accordingly to the type of shock suffered.

Arrange transportation to a hospital as quickly as possible.

If arms and legs are injured, keep them raised. WARNING:

If medical aid is not available within one hour and if the victim is conscious and if it does not present retching problems, administer a salt and soda liquid solution to be drank:

1 full teaspoon of salt and half teaspoon of sodium bicarbonate for every 250 ml (8.5 oz) of tepid water, let the victim sip this solution slowly, for about four times (1/2 glass over a period of 15 minutes passing). Stop this operation if retching problems occur. Do not administer alcoholic solutions. 2.2.1.2 Less severe burns (1st and 2nd degree)

Apply on the burns cool (not icecold) gauze compresses using the cleanest available cloth.

Do not break blisters, not remove tissue, not remove adhered particles of clothing, or not apply any ointment.

CALL FOR MEDICAL ASSISTANCE AS SOON AS POSSIBLE IN ALL CASES 2.3 Workplace characteristics 2.3.1 Room characteristics In order to work freely on the equipment and to be able to perform the relative installation or maintenance operations, it is necessary to keep a minimum distance from the walls on all sides of the machine. The room must be equipped with an appropriate system of clean and dustfiltered air ven-

tilation with a flow rate suitable for the characteristics of the equipment operating in the room itself. Outgoing exhausted air must be conveyed directly outside. If the ducts length or size is such to presume it may be causing a consistent loss of load to the air flow rate it is neces-

sary to add an extraction apparatus. At the conveyors outlet intrusion protection devices must be provided against insects or other kinds of animals and suitable precautionary measures against liquid or other materials intrusion must be applied. The equipment can operate properly if the temperature ranges from 5oC to +45oC (23oF to 113oF), with 95% RH noncondensing at +40oC (104oF). 2.3.2 Electrical system features The electrical network installation has to be set in accordance with the regulations in force. The power supply network must allow an appropriate power provision according to the laws in force in the Country of installation on the quality of the electrical energy supply service. It is highly recommended to use a transformer/network separator and a reduction network for discharging high voltage. 16 Safety Provide a protected under load disconnector (circuit breaker or fuses) with appropriate disconnection power and capacity according to the absorption characteristics of the equipment model. Use cables of an appropriate size with respect to the rated absorbed current. Earth connection must be performed according to the applicable laws. Special care must be applied to the earth connection of the antenna system since it is exposed to electrical atmospheric events. Never forget that despite the earth connection of the equipment frame and the whole antenna system, it is always dangerous to operate on the equipment in the event of bad weather with atmospheric discharge. In fact, in the event of high energy discharge

(lighting), the equipment frame can instantly reach very dangerous voltage levels, due to the earth connection inductance. For this reason, the equipment should be installed in rooms accessible to maintenance personnel only and for the time necessary for repairs and checks only. Safety 17 2.4 Exposure evaluation Exposure assessment requires the identification of electric field values in places where the presence of people may occur. The field values must refer to the type of stay and the exposed subjects, according to the provisions of current legislation. The identification of the electric field values can be carried out in various ways, depen ding on the need for precision and the fact that one intends to perform a prediction, or a subsequent verification. We intend to provide below elements that may be useful in the evaluation and measure-

ments of electromagnetic fields, with particular reference to sound and television broad-

casting systems. 2.4.1 Calculation in the free space A first approximate evaluation can be made by placing the following hypotheses:

i) ii) source located in far field absence of obstacles The first hypothesis (i) must be previously verified by applying the equation:

where d represents the distance between source and evaluation point, D the physical dimension of the source and the wavelength of the field. Under these hypotheses, the electric field at distance d from the source is:

d D

E =

Pr =

Pt 4d2 where Pt is the power transmitted (ERP) in the direction of the evaluation point. Introducing the polarization of the electric field, impressed by the particular type of antenna used in transmission, the relation 2 must be applied to the three components Ex, Ey, Ez of the field; the expression of the total electric field becomes:

E =

Ex 2 + Ey 2 + Ez 2 1. 2. 3. 18 Safety In the specific case of broadcasting plants for sound and television broadcasting, the fol-

lowing recurrent characteristics can be found:

a. the source is not isotropic, so the ERP should be calculated in the direction of the evalua-

tion point b. in the case in which the worst case of exposure is concerned, it can be applied the expression 2 in which the maximum transmitted ERP power is considered, regardless of the direction, ignoring the radiation characteristics of the antenna system in the hori-

zontal and vertical plane c. the polarization of the field is almost always vertical in the case of systems for sound broadcasting, while it can be vertical, horizontal or mixed in the case of television broad-

casting. In all cases, the decomposition of the power transmitted in the various polariza-

tion components and the subsequent recombination by means of formula 3 allows, firstly, to disregard the polarization of the field and to directly apply the expression 2 d. in the case of multiple sources, the total expression 4. EtotN

Foldback acts if the load mismatch increases slowly. If the event is fast (examples: a spark into a connector, the detachment of a transmission line, a short circuit and so on), the protection acts quickly. The activation of this feature is shown on display and via telemetry as alarm no. 026. 4.3.1.2 IPC (Intelligent Power Control) When the equipment is properly working, the IPC keeps the output power constant within 1% of the target set, irrespective of mains voltage, temperature and load vari-

ations. This greatly contributes to making the equipment insensitive to its working conditions. The IPC also allows to optimize the efficiency of the RF section by making work the MOSFETs constantly at maximum efficiency, thus minimizing overall electrical con-

sumption. 4.3.1.3 Safety Management (Lifextender) The Safety Management consists of algorithms to perform real-time analysis of the transmitter's operating status. It works in order to maintain the output power set, according to kind and severity of any anomalies (internal or environmental) which may occur. The Safety Management may perform an output power reduction proportional to the severity of the anomaly that occurs, in order to avoid the propagation of the fault. The algorithms act at different levels and in various sections of the equipment: Ther mal Management on the RF unit; Current Management, Fault Management and Ther mal Management on the power supply units; Fault management on the RF unit; Cool ing Management on the fans. Thermal Management on the RFs group (Lifextender) When the temperature measured in close proximity to the MOSFET exceeds 72C, an algorithm intervenes that reduces the output power to a value such as to keep the temperature back within a still acceptable value. If this appens, an alarm of Rf thermal derating (no.010) is sent. If this algorithm does not manage to maintain the temperature below 75C, the trans mitter is switched off. 32 Product description Current Management on the power supply (Lifextender) This is activated when the maximum current rated for continuous operation of the power supply is exceeded. This value is lower than deliverable current limit and represents the threshold which can be exceeded only for short periods (maximum 1 minute each time). If this situation occurs, the PSU current derating function is activated (alarm 013 and, if necessary, alarm 014) and the ALC management algorithm, running in correct wor-

king mode, is replaced by another one in which the current delivered by the power supply units has the highest priority in this case and the RF output power derated conseguently. The current derating is deactivated when the power delivered rises to the value set by the user and the maximum current provided by the power supply units is less than or equal to the maximum value allowed for continuous operation. Thermal Management on the power supply (Lifextender) The power supply management algorithm that works to maintain the temperature of the power supplies below a safe value is the same that operates in the RF section and is logically connected in OR with that the derating (acting directly on the output power) is activated when the power supply temperature exceeds 72C (162 F). Fault Management on the RF modules (Lifextender) It allows to reduce the maximum RF output power according to the number of correctly working RF amplifier modules, so that they don't could be stressed. A special algorithm correlates the optimal RF output power with the number of these modules. To prevent any damage, the fans speed is increased to the maximum value. Cooling Management on the RF modules (Lifextender) In respect to the current cooling requirements, the fan speed rotation is automatically adjusted from a minimum of 50% to a maximum of 120% approx. (these values may change according to the models of used fan). The cooling demand evaluation is based on accurate measurements of the temperature close to each MOSFET and to the power supply units. The Cooling Management aims to:

1. extend the life of the fans;

2. minimize the quantity of dust which can be carried by the air flow;

3. allow the safe operation of the equipment also under extreme temperature condi tions;

4. ensure that temperatures of mosfets and power supplies remain as stable as possi ble to avoid thermal and mechanical stress;

5. reduce the energy consumption when a strong heat extraction is not needed. Without Lifextender, the fans always operate at 100%. Product description 33 34 Product description 5 Block diagrams 5 Block diagrams 5.1 Block diagrams

(Amplifier) EXT REF MISSING

(Exciter) The RF input power level is correct. External reference (10Mhz) absent. INCREASE PILOT PWR

(Amplifier) The RF input power level is to low but not dan-

gerous and must be increased. MPX NO AUDIO

(Exciter) The MPX input level has remained lower than the minimum set level for the set time. DECREASE PILOT PWR

(Amplifier) The RF input power level is to high but not dan-

gerous and should be decreased. AES/EBU NO AUDIO

(Exciter) The AES/EBU input level has remained lower than the minimum set level for the set time. BAD INPUT RF PROTECTION

(Amplifier) RF input power level out of limit. The external modulator has been disconnected. STEREO NO AUDIO

(Exciter) The STEREO inputs level is lower than the minimum set level for the set time. STREAMING NO AUDIO DIG MPX NO AUDIO BATTERY LOW REFERENCE VOLTAGE ERROR No sufficient level audio streaming signal for the set time. No sufficient level digital MPX audio signal for the set time. The CPU backup battery is low. In case of no mains, the clock will lose settings. The internal refer. voltage is no longer reliable and the measurements will be incorrect. Some wrong alarms or warnings could be sent. FAN 3 ERROR Fan no.3 has stopped working properly. DRAIN VOLTAGE CONTROL ERROR RTC FAULT VDS voltage is more than 4V different from the expected value. The adjustment is fixed at the last valid value. It restarts when the difference becomes less than 4V. The clock says a wrong time; it isnt possible to cerrect automatically. Some settings, such as clock power target, will not run correctly. RTC USER UPDATED The user has updated the internal clock. 067 RTC AUTOMATIC RECOVERY CLIPPER ON The apparatus has updated the internal clock automatically. Audio clipper protection has been activated to prevent a frequency deviation excess. CLIPPER OFF Audio clipper protection no longer actives. RTC SERVER NTP UPDATED The internal time reference has been updated via NTP server. 62 User instructions 6.3 External connectable devices 6.3.1 Connecting to a LAN/PC Connect the apparatus to PC via LAN using a switch or any other device such as a router.
