Take the unit from burn-in-bench to Q.C and play it immediately. Keep the line 120V A.C.3. Check physically and check the components

8、.-check all capacitor and devices direction. Capacitor stand up right way i.e. check co-solder.-check any missing parts.-check all fuse sockets.-check main board tight up with screw and washer.-check any screw missing.-check balance lock working smoothly.-check all output transistors position with p

9、ad.-check main transistors position with pad.-check main transformer tight very well.4. Adjust bias 26mV for every output devices for both channels. Wait 7 to 8 minutes aftereach adjustment. Also adjust offset to 0mV.5. Measure rail and pre-driver voltage.6. Measure A.C voltage for bridge.7. Measure

10、 supply voltage for relays. +15V and 15V for both channels. +12V and 12V.8. Measure reference voltage 8.1V on both channels.9. Measure reference voltage for protection 78V.10. After setting the bias, connect load and input signal. Check output signal. Check phasewith input signal.11. Measure frequen

Remove the units cover by removing the 8 Philips screws. There are 4 on t

39、op and 2 on each side.2. Remove the Video Board. To remove the Video Board first remove the 17 #4 hex screws that secure the board to the rear panel of the unit. Pleasenote that the screw located between the Composite Video Out and the S-video In is attached to the rear panel with a 3/16 keep nut. R

40、emove the two 3/16 nuts that secure the RS232 Port to the rear panel. Next disconnect the three ribbon cables from the Video Board. Remove the eight #4 hex screws that secure the board to the standoffs. Remove Video Board.3. Remove (Generation 5) DSP Board. To remove the DSP Board remove the four #4

41、 hex screws that secure the board to the standoffs.4. Install (Generation 6) DSP Board. Align the new board so that the connectors in line. Place the new board on the standoffs making sure the connector seats properly. Reinstall the four #4 hex screws. Do not over tighten.5. Replace Video Board by r

42、eversing step 2. Make sure that the ribbon cables are properly aligned with the connectors on the Video Board.6. Connect the upgraded SSP-30 to the programming computer with a serial cable (9 pin) and the supplied baud rate converter. The cable goes between the serial port of the programming compute

43、r and the baud rate converter which should be plugged into the RS232 port on the back of the unit.7. Open/Run the upgrade software (SSP30.customizer.exe).8. From the menu, select Classe_SSP30_GEN6_VO1.cfg9. Update the configuration file using the Update Button.10.Verify the connection using the Check Connection Button. If the connection fails, check the power and data cable connections. Note. The SSP30 must be powered on during this procedure. 11.When the connection shows “live”, use the Configure Button to configure the unit.
