If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that

34、 all the protective devices such as insulation barriers, insulation papers shields are properly installed. 3. After servicing, carry out the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.1.1. LEAKAGE CURRENT COLD CHECK 1. Unplug the AC cord and conne

35、ct a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the chassis

36、, the reading should be between 1M and 5.2M. When the exposed metal does not have a return path to the chassis, the reading must be 1.1.2. LEAKAGE CURRENT HOT CHECK 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k, 10 watts resist

37、or, in parallel with a 0.15F capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1. 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic par

38、t, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent) may be used to make the hot checks, leakage current

39、must not exceed 1/2 milliamp. In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer. Figure 1 1.2. Before Repair and Adjustment Disconnect AC power to discharge unit

40、 AC Capacitors as such C5700, C5701, C5703, C5704, C5705 through a 10 , 10 W resistor to ground. Caution: DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid ove

41、rcurrent. Current consumption at AC 230 V, 50 Hz in NO SIGNAL mode volume minimal should be 600 mA. (For E/ EG) Current consumption at AC 230V240 V, 50 Hz in NO SIGNAL mode volume minimal should be 600 mA. (For EB) 1.3. Protection Circuitry The protection circuitry may have operated if either of the

42、 following conditions are noticed: No sound is heard when the power is turned on. Sound stops during a performance. 6 SA-PT550E / SA-PT550EB / SA-PT550EG The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, o

43、r if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used. If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute. Note: When the

44、 protection circuitry functions, the unit will not operate unless the power is first turned off and then on again. 1.4. Safety Parts Information Safety Parts List: There are special components used in this equipment which are important for safety. These parts are marked byin the Schematic Diagrams &

45、 Replacement Parts List. It is essential that these critical parts should be replaced with manufacturers specified parts to prevent shock, fire or other hazards. Do not modify the original design without permission of manufacturer. Table 1 Reference No.Part No.Part Name & DescriptionRemarks PC5701B3
