DIAGRAMFORKLARING

På diagrammerne er der angivet typenumre på transistorer og IC'er. Hvis positionsnummeret er efterfulgt af en stierne, skal reservedelsnummeret altid benyttes, da denne komponent er specielt udvalgt. f.eks. TR102*.

Komponenttryk og koordinatsystem

De største printplader er forsynet med komponenttryk og et koordinatsystem på både print- og komponentside.

På diagrammerne er enhver komponent forsvnet med et koordinatnummer. Dette fortæller i hvilket koordinat på printpladen, komponenten er placeret. Koordinatnumrene er angivet med mindre skrifttype end positionsnumrene.

Styrekredsløh

I visse styrekredsløb er den aktive tilstand angivet med en funktions- eller bogstavsangivelse. Denne kan eksempelvis være ST.BY. = »low« i stand-bystilling eller ST.BY. = »high« i stand-by-stilling.

Ledningsforbindelser

Ledningsforbindelserne på diagrammerne er samlet i »bundter«. De enkelte ledninger er forsynet med en af følgende koder:

INTERN FORBINDELSE PÅ EN DIAGRAMSIDE

INTERNAL CONNECTION ON ONE DIAGRAM

Interne forbindelser på en diagramside angives med et tal. Knækket på ledningen viser, i hvilken retning. den anden ende af ledningen findes.

FORBINDELSE TIL EN ANDEN DIAGRAMSIDE

DIAGRAM A DIAGRAM C

et tal samt et bogstav for det diagram, forbindelsen går til.

Forsyningsspændinger

Alle forsyningsspændinger i diagrammerne er angivet med en pil og en spændingsangivelse.

Eksempel

Ved siden af spændingsangivelsen står der f.eks. 7 CON. Dette betyder, at den pågældende forsyningsspænding går til 7 steder på den pågældende diagramside (7 CON. = 7 connections).

Bang&Olufsen

EXPLANATION OF DIAGRAM

Type numbers of transistors and ICs are indicated on the diagrams

If the position number is followed by an asterisk the spare part number must always be used because the component in question has been specially selected eg TR102*

Component print and coordinate system

The largest PCBs have component prints and a coordinate system on both the print and the component side

On the diagrams every component has a coordinate number. This indicates in which coordinate on the PCB the component is situated. The coordinate numbers are written in smaller print types than the position numbers.

Control Circuit

In certain control circuits the active mode is indicated by a function term or by an abbreviation. This may be e.g. ST.BY. = low in the stand-by mode or ST.BY. = high in the stand-by mode.

Wiring Connections

The wiring connections on the diagrams are assembled in 'bundles' The individual wires are provided with one of the following codes:

Bang&Olufsen

Stelsymboler

Der anvendes fire forskellige stelsymboler i appa-

$\perp$ = Stel = Signalstel

= Grov stel

Ground Symbols

Four different ground symbols are used in the set.

= Ground = Signal ground
= Chassis
= Coarse ground

Page 9

SYMBOL FOR SIKKERHEDSKOMPONENTER

Ved udskiftning af komponenter med dette symbol skal der anvendes komponenter med samme reservedelsnummer. Den nye komponent skal monteres på samme måde som den udskiftede.

MÅLEBETINGELSER

Alle DC-spændinger er målt i forhold til stel med et voltmeter med en indgangsimpedans på 10 Mohm.

DC-spændingerne er opgivet i volt (V), f.eks. 0,7 V.

Alle oscillogrammer og AC-spændinger er målt i forhold til stel med et oscilloskop eller et voltmeter med en indgangsmodstand på 1 Mohm.

AC-spændingerne er opgivet i millivolt (mV), f.eks. 660 mV.

Advarsel

Det gule og sorte mærkat på CD-afspilleren er en advarsel om, at apparatet indeholder et lasersystem og er klassificeret som et klasse 1 laserprodukt. Apparatet må kun åbnes af fagteknikere.

CD laserdiode:

Bølgelængde Effekt

780 mm ±20 nm, 30°C 2 mW ±0,1 mW, 30°C

SYMBOL OF SAFETY COMPONENTS

When replacing components with this symbol, components with identical part numbers must be used. The new component must be mounted in the same way as the one replaced.

MEASURING CONDITIONS

All DC voltages have been measured in relation to ground with a voltmeter with an input impedance of 10 Mohms.

The DC voltages are stated in volts (V), e.g. 0.7 V.

All oscillograms and AC voltages have been measured in relation to ground with an oscilloscope or a voltmeter with an input resistance of 1 Mohm.

AC voltages are stated in millivoits (mV), e.g. 660 mV.

Caution

The use of any controls, adjustments or procedures other than those specified herein may result in hazardous radiation exposure.

The black and yellow label on the compact disc player serves as a warning that the apparatus contains a laser system and is classified as a class 1 laser product. The apparatus must be opened by qualified servicemen only.

Kontrol af laserforsyning

Laseren, laserforsyningen i 8IC1 og monitordioden danner et tilbagekoblings-system. En fejl i laserforsyningen kan medføre, at laseren ødelægges.

Da det er umuligt at kontrollere og reparere et tilbagekoblingssystem, hvor en af komponenterne mangler, kan nedenstående kredsløb bruges til at kontrollere laserforsyningen.

Den grønne LED udgør laseren. Spændingen over 18 The green LED replaces the laser. The voltage ohms modstanden udgør monitor-tilbagekoblingsspændingen. 33 ohms modstanden og omskifteren gør det muligt at ændre strømforbruget fra laserforsyningen.

Checking the laser supply

The laser, the laser supply in 8IC1 and the monitor diode form a feed-back system. A defect in the laser supply may result in destruction of the laser.

As it is impossible to check and repair a feed-back system if one part of the system is missing, the laser supply can be checked by means of the below circuit.

across the 18-ohm resistor is the feed-back voltage for the monitor. The 33-ohm resistor and the switch make it possible to change the power consumption from the laser supply.

Grøn LED f.eks. CQY94 bestillingsnr. 8330054.

Fleks-printet tages ud af P2 på servo-PCB'en.

Ovenstående kredsløb loddes på P2 på servo-PCB'en.

SI (ben 6 på 8IC1) kortsluttes til stel.

Når SI (Start initialization) er low, kan laserforsyningen tændes i service position 1, ved at kortslutte TESTMODE stikket kortvarigt. Tryk derefter CD og PLAY.

LO-spændingen på ben 10 af 8P2 måles.

S1 afbrudt LO fra 1,8 V til 2,3 V LM fra 170 mV til 220 mV Den grønne LED lyser svagt

S1 kortsluttet: LO fra 1,8 V til 2,3 V LM fra 170 mV til 220 mV Den grønne LED lyser svagt

Når S1 skiftes fra kortsluttet til afbrudt, vil LED'en lyse kraftigere i et kort øjeblik Tilbagekoblingssystemet bevirker, at der går samme strøm i LED'en, hvad enten S1 er kortsluttet eller afbrudt.

Green LED, e.g. CQY94, part no. 8330054

Remove the flex PCB from P2 on the servo PCB.

Connect the above-mentioned circuit to P2 on the servo PCB.

Connect SI (pin 6 of 8IC1) to ground.

When SI (Start initialization) low, the laser supply can be switched on by short circuit the socket TESTMODE briefly. Then press CD and PLAY.

Measure the LO voltage on pin 10 of 8P2.

S1 open: LM from 170 mV to 220 mV The green LED emits little light

S1 closed: LO from 1.8 V to 2.3 V LM from 170 mV to 220 mV The green LED emits little light

During the change from S1 closed to S1 open, the LED will shortly emit more light than usual. The feed-back system ensures that the same amount of current passes through the LED irrespective of whether S1 is open or closed.

Mains lead

The internal mains leads to the Transformer PCB21 must be connected as follows:

male (small) = IN (PCB21) female (large) = OUT (PCB21)

ISOLATIONSTEST

Ethvert apparat skal isolationstestes efter at det har været adskilt. Testen udføres når apparatet igen er helt samlet og klar til udlevering til kunden.

Isolationstest for Beosystem 2500

Isolationstesten udføres på følgende måde: De to stikben på netstikket kortsluttes og tilsluttes en af terminalerne på isolationstesteren. Den anden terminal fra isolationstesteren tilsluttes stelbenet i hovedtelefonstikdåsen.

OBS!

For at undgå beskadigelser på apparatet er det vigtigt, at begge terminaler fra isolationstesteren har virkelig god mekanisk kontakt.

Der drejes nu langsomt med spændingsreguleringen op isolationstesteren indtil en spænding på 1,5 – 2 kV er opnået. Her skal den holdes i 1 sekund, derefter drejes der langsomt ned for spændingen igen.

Der må ikke på noget tidspunkt under testen forekomme overslag.

INSULATION TEST

Each set must be insulation tested after dismantling. The test is to be performed when the set has been re-assembled and is ready for delivery to the customer.

Insulation test for Beosystem 2500

Make the insulation test as follows: Short-circuit the two plug pins of the mains plug and connect one of the terminals of the insulation tester. Connect the other terminal of the insulation tester to the chassis pin of the headphone socket.

N.B.!

To avoid ruining the set, it is essential that both insulator test terminals are in really good mechanical contact.

Now turn slowly the voltage control of the insulation tester until a voltage of 1.5 - 2 kV is obtained. Hold it there for 1 second, then turn slowly the voltage down again.

At no point during the testing procedure any flashovers are permissible.
