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

17、, see to it that 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

18、 cord and connect 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

19、 to the chassis, 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, 1

20、0 watts resistor, 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 expose

21、d metallic part, 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, le

22、akage current 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 d

23、ischarge unit AC Capacitors as such (C5700, C5701, C5702, C5703, C5704, C5705, C5706) 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

24、 using a variac, to avoid overcurrent. Current consumption at AC 240 V, 60 Hz in NO SIGNAL mode at volume minimum should be 600 mA. 1.2.1.Caution for fuse replacement RadioFans.CN 收音机爱 好者资料库 4 1.3.Protection Circuitry The protection circuitry may have operated if either of the following conditions a

25、re noticed: No sound is heard when the power is turned on. Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicate

26、d 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 protection circuitry functions, the unit will not operate un

27、less the power is first turned off and then on again. 5 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 by () in the Schematic Diagrams & Replacement Parts List. It is essential that these crit

28、ical 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.

33、lectrostatic Discharge (ESD) to Electrostatic Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some f

34、ield-effect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD). 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any

35、ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES device

36、s, place the assembly on a conductive surface such as alumi- num foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not cl

37、assified as “anti-static (ESD protected)” can generate electrical charge sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package until immedia

38、tely before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or compara- ble conductive material). 7. Immediately before removing the protective material from the leads of a replacement ES device, touch

39、the protective material to the chassis or circuit assembly into which the device will be installed. Caution: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of you
