Allgemeiner Teil
Allgemeine Hinweise
Vor dem Öffnen des Gehäuses den Netzstecker ziehen!
Achtung: ESD-Vorschriften beachten
Leitungsverlegung
Bevor Sie die Leitungen und insbesondere die Masseleitungen lösen, ist
die Leitungs ver legung zu den einzelnen Baugruppen zu beachten.
Nach erfolgter Reparatur ist es notwendig, die Leitungsführung wieder
in den werkseitigen Zustand zu versetzen um evtl. spätere Ausfälle
oder Störungen zu vermeiden.
Durchführen von Messungen
Bei Messungen mit dem Oszilloskop an Halb leitern sollten Sie nur
Tast köpfe mit 10:1 - Tei ler verwen den. Außerdem ist zu beachten, dass
nach vorheriger Messung mit AC-Kopp lung der Koppelkondensator
des Oszillo skops auf geladen sein kann. Durch die Ent ladung über das
Messobjekt können Bau teile beschä digt werden.
Messwerte und Oszillogramme
Bei den in den Schaltplänen und Oszillogrammen angegebenen
Messwerten handelt es sich um Näherungswerte!
Austausch der Chassisplatte
Nach Austausch der Chassisplatte müssen alle Einstellungen im Service
Mode nach Tabelle "Grundeinstellwerte" (Punkt 1 im Kapitel "Serviceund Sonderfunktionen" auf Seite 1-25) eingestellt werden.
Spare Parts Lists .................................. 3-1…3-3
General Section
General Notes
Before opening the cabinet disconnect the mains plug!
Attention: Observe the ESD safety regulations
Wiring
Before disconnecting any leads and especially the earth connecting
leads observe the way they are routed to the individual assemblies.
On completion of the repairs the leads must be laid out as originally
fitted at the factory to avoid later failures or disturbances.
Carrying out Measurements
When making measurements on semi-con duc tors with an oscillo scope,
ensure that the test probe is set to 10:1 dividing factor. If the previous
measurement was made on AC input, please note that the coupling
capacitor in the oscilloscope will be charged. Discharge via the item
being checked can damage the components.
Measured Values and Oscillograms
The measured values given in the circuit diagrams and oscillograms
are approximates!
Change of the Chassis Board
After changing the chassis board all settings in the service mode must
be done according to the table "Basic Settings" (point 1 in chapter
"Service and Special Functions" on page 1-25).
