    Современные кондиционеры обладают таким функциональным наполнением, что при возникновении неисправности в работе система управления не только проинформирует о наличии поломки, а также диагностирует тип этой поломки и выведет код ошибки на индикатор внутреннего или внешнего блоков.

    Обычно коды ошибок кондиционеров указаны в инструкции по технической эксплуатации кондиционера, которая прилагается к самому прибору при покупке.

    Не игнорируйте сообщения о неисправности, поскольку «откладывание на потом» ремонта и обращения в сервисный центр только усугубит проблему и приведет к более серьезному дорогостоящему ремонту. А вам, как владельцу техники, это будет стоить дополнительно потраченных нервов, времени и средств.

    If you require any advice or assistance regarding your Sharp product, please visit our web-site www.sharp.co.uk/support.aspx Customers without Internet access may telephone 0870 787 4837 during office hours (or (01) 843 4711 if telephoning from Ireland).

    NOTES FOR USERS IN THE U.K AND IRELAND

    The mains lead of this product is fitted with a non-rewireable (moulded) plug incorporating a 5A fuse. Should the fuse need to be replaced, a BSI or ASTA approved BS 1362 fuse marked or and of the same rating as above, which is also indicated on the pin face of the plug must be used.

    Always refit the fuse cover after replacing the fuse. Never use the plug without the fuse cover fitted.

    In the unlikely event of the socket outlet in your home not being compatible with the plug supplied, cut-off the mains plug and fit an appropriate type.

    DANGER:

    The fuse from the cut-off plug should be removed and the cut-off plug destroyed immediately and disposed of in a safe manner.

    Under no circumstances should the cut-off plug be inserted elsewhere into a 13A socket outlet as a serious electric shock may occur.

    To fit an appropriate plug to the mains lead, follow the instructions below:

    IMPORTANT:

    The wires in the mains lead are coloured in accordance with the following code:

    Blue : Neutral Brown : Live

    As the colours of the wires in the mains lead of this product may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

    The wire which is coloured blue must be connected to the plug terminal which is marked N or coloured black.

    The wire which is coloured brown must be connected to the plug terminal which is marked L or coloured red.

    Ensure that neither the brown nor the blue wire is connected to the earth terminal in your three pin plug.

    Before replacing the plug cover, make sure that:

    If the new fitted plug contains a fuse, its value is the same as that removed from the cut-off plug.

    The cord grip is clamped over the sheath of the mains lead and not simply over the lead wires.

    IF YOU HAVE ANY DOUBT, CONSULT A QUALIFIED ELECTRICIAN.

    PRECAUTIONS FOR USING LEAD-FREE SOLDER

    1. Employing lead-free solder

    «MAIN, POWER, DISPLAY, INTERFACE, AMPLIFIER, SUBWOOFER PWB» of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWB and service manuals. The alphabetical character following LF shows the type of lead-free solder.

    Example:

    Indicates lead-free solder of tin, silver and copper.

    2.Using lead-free wire solder

    When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks.

    As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.

    3.Soldering

    As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 C which is higher than the conventional lead solder by 40 C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering condition.

    Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on and off the power of the bit as required.

    If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.

    When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper. Be careful when replacing parts with polarity indication on the PWB silk.

    Lead-free wire solder for servicing

    Ref No.

    Parts No.

    [8] ASPM Test Mode (For EU Destination)

    Outline

    At Tuner RDS ASPM operation need to be confirm for EU(H) model only.

    Power-ON in TUNER function, and scanning frequency from 105.00MHz — 108.00MHz.

    And RDS station Preset Memory maximum 3 station.

    TEST Mode Operation

    Power ON in TUNER Function 106.50MHz FM Stereo Band. At same time Only Preset No. ch1 — ch3 leave blank and all ch4 — ch40 memory at 87.50MHz FM Stereo Band.

    With the press of ASPM key, ASPM operation will start at 105.00MHz frequency.

    If RDS station received Preset will memory from ch1. (There is no need to memory PS name in ASPM Test Mode. If preset change during Test Mode Frequency will be display first)

    Scan will stop after reach frequency 108.00MHz, and return to frequency 106.50MHz FM Stereo.

    To confirm Memory content display will show Preset Number and frequency for ch1until ch3. After display are confirmed frequency will return to 106.50MHz FM STEREO. (Display method same with Tuner display during Normal POWER ON.)

    If ASPM key is press again, ASPM operation will start from 2 untill

    5.

    While scanning if 3 station memorized, Scanning will stop and operation 4 and 5 will take place.

    Afterward, even if ASPM key input detect ASPM operation will not be execute. «__END__» displayed and operation canceled.

    AN-GR500H

    Additional

    Other then above, operation for ASPM are same with User operation. So, when 1st time scan with same PI code Station with most strong signal will be memory and will not be memory many time. For 2nd and more station with same frequency will not be memory.

    But, if different station with same PI code (same PI with different frequency station), station one with most strong signal will be memory.

    So, station that already memorized before scan will be ignore. Therefore, even station with same same PI code after 3 times ASPM scan, It is possible that, 3 station will be memorized in Signal Strong order.

    After Test Mode end only Tuner preset memory will be reset and set to default. Ohers Memory, no need to be initialize.

    CHAPTER5. 5. CIRCUIT DESCRIPTION

    [1]WAVEFORMS OF CD CIRCUIT

    [1]To Check And Cancel Protect Circuit Detection Line

    1.After the power is turned on, the microprocessor (ICM7) built in this model continuously monitors the following defective operation. If any abnormality occurs, all power is shut down except in the microprocessor drive circuit.

    1)An abnormal drop of each regulator output voltage.

    (The protection circuit operates when the regulator output voltage is below 1.5 V.) The power is shut down immediately with no display.

    2)Defect of the cooling fan motor and the cooling fan drive circuit. (Stoppage, etc.) The power is turned off after “FAN LOCK” is displayed.

    3)Over voltage or reduced voltage of power supply.

    The power is shut down immediately with no display when voltage is abnormal.

    2.Failure detection conditions of the built-in microprocessor, check of the detection line and solution.

    Conditions

    1)To detect failure according to voltage of the microprocessor ICM7 pin 91.

    2)Abnormal if pulse signals are not input into the pin 5 (FAN LOCK) for more than 5 seconds.

    3)Abnormal if the voltage of the pin 97 (+B CHECK) is lower than 1.2 V or higher than 3.0 V.

    1.Check of the detection line and solution

    NOTE: If the microprocessor detects failures of 1), 2) and 3) above, it does not operate protectively when its PROTECT, and +B CHECK detection lines are disconnected.

    When these failures are caused by output short-circuit of each regulator, components and PWB of the regulator may burn out. If the cause is not clear, do not disconnect the detection line.

    (Even if any failure is detected, conduction is available for 0.5 second. You can check conduction by an oscilloscope, etc. However, a tester is not available due to rapid rise and decay of voltage.)

    1. When output voltage of each regulator drops abnormally.

    Connect the oscilloscope to the regulated output of the regulator and power on the system. If the voltage is significantly lower than that shown in the circuit diagram (approx. 1.5 V or less), the regulator itself and the destination circuit are suspected.

    [2] Failure Detection Identification Using STANDBY LED

    1. Identification format using STANDBY LED

    If any failure is detected, STANDBY LED blinks red after power off (see Fig. 1 below). You can identify the failure state by checking which LED output number from the frame head is blinking 4 times each for 2 seconds.

    Fig. 1 shows the LED output No. 2. is blinking due to failure.

    Normally, LED light up for 2 seconds and light off for 1 second on a 3-second cycle (6 times from No. 1 to No. 6). For No.7, LED light off for 3 seconds, showing the frame end (for recognition of the frame head).

    In No. 2, LED blinks alternately at shorter intervals than usual for failure identification. For failure status, refer to the appendix, “STAND-BY LED Error Message”.

    CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

    [1] Notes On Schematic Diagram

    Resistor:

    To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.

    Capacitor:

    To indicate the unit of capacitor, a symbol P is used: this symbol P means pico-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/ withstand voltage” is used.

    (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type

    (P.P.): Polypropylene type

    Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

    The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given.

    1.In the tuner section, indicates FM stereo

    Parts marked with “ “ (

    ) are

    important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
