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).
