1) do not eat coins
1, to determine whether the normal power coin
( detection are as follows, first coin power out again on the power supply, the coin should be as follows: )
2, simple, and power on again when the electromagnet will jump, then heard" BI " sound, the coin on the normal.
In 3, multiple coin type, display from "00" to" 99" after all again to "00", after the electromagnet jump, then hear the BI sound as normal.
4, such as power on again without any response, open circuit board cover, the multimeter is used to measure the voltage of the power supply is U3 first pin voltage is normal, the first foot is a voltage of about 12V, if the 12V voltage is normal, then measuring third feet U3 third feet of voltage, voltage should be about 5V, such as the third output voltage exceeds 5V, then the voltage stabilizing tube 7805 burnt out, be replaced. If two voltage were normal, coin or no response, the coin should be returned to the manufacturers institute.
5, if only to hear the " BI " sound, while the electromagnet is not beating, then usually has only three possible,
( 1) the electromagnet is broken, if not broken electromagnet which resistance should be around 50 ohms.
( 2) such as an electromagnet is not bad, then the measurement of Q2 ( D471 ) three transistor is breakdown.
( 3) if the above are not bad, may be D1 ( 4148) is broken.
( 4) if no problem, then returned to the manufacturers processing.
<P src=" 6，如电磁铁跳后没听到“BI”一声，那么拆开电路板盖，通电后，用电表测量测币线圈（用黑表笔接地，红表笔测线圈两端）线圈的两只脚电压应在3-4V之间，如电压不正常（1，如线圈的一个脚有5V左右，而另一个脚却只有0.3V，那么说明是线圈断路，2，如线圈的两个脚都为5V，那么说明Q1坏掉。）如电压都正常；那么将表笔短路Q5的1，2脚，如听到有“嚓嚓”声，那说明蜂鸣器没坏，Q5坏掉；如没听到“嚓嚓”声，那说明蜂鸣器坏了。">6, such as an electromagnet after the jump to hear " BI " sound, then opened the circuit board cover, when energized, meter measuring coin coil ( with black table document connected to, the red pen measuring coil ends of two feet ) coil voltage should be in 3-4V, if the voltage is not normal ( 1, such as a coil a foot is about 5V, and another foot is only 0.3V, then is the coil circuit, 2, such as a coil of two feet for 5V, then Q1 broken. ) If the voltage is normal; the pen short circuit Q5 1, 2 feet, such as hear" Tsatsa" sound, then the buzzer not bad, Q5 broken; such as hear " Tsatsa" sound, then the buzzer is broken.
If the above are no problem, it may be a coin collector EPROM memory is cleared, so long as to save some money.
2) will be called.
In 1, a setting switch is placed in the" start".
2, such as a switch on the" start" position have called it, then it is likely that photoelectric coupling pipe problems.
The multimeter is used to measure LD3, LD4, LD7 ( black ) to the ends of the tube voltage, voltage range should be in 0.1-0.4V is normal, if the above 0.4V, so may be a reflective film (i.e. light tube pointing to the transparent sheet ) is dirty, clean it again if the measurement, is also higher than that of 0.4V, then the red, black pen measurements of LD1, LD2, LD5 all the ends of the tube potential difference, the potential difference is about 1V, such as the measurement results of normal, so that as the black tube damage. Will change to be measured.
3) eat coins do not send a signal or send the wrong signal
1, fast / slow switch is placed in a suitable medium machine receives the state, such as improper will send error signal.
2, normally open / normally closed switch if the wrong position.
In 3, Q3 three transistor is damaged.
4) eat coins will call
In 1, a photoelectric tube LD7 is normal.
In 2, the coin chute bottom (LD7 ) light, if there is debris or interference affects the money rolling speed.
5) the electromagnet has been jumping or has been pulled
In 1, just when the electromagnet has electricity, beating, as the electromagnet protecting two pipe weld.
In 2, the electromagnet has pull (i.e., always eat coins state ) that is due to Q2 three diode breakdown.
Note: the diode measurement mode, the multimeter to diode file, with the black table document connected diode marked end ( diode standard polarity annotation is usually a white or black ring ring ), the red pen is connected with the other end, the multimeter should display ( 500-.700 ) for the normal.
The three transistor measurement, Q1, Q2, Q3, Q4, Q5 measurement for the multimeter to diode file, red table document connected three. Third, with a black pen measuring two feet, at first, multimeter should display ( 500-.700 ) for the normal</DIV></DIV>
