7) BALL SUPPLY MOTOR ERROR [E.71],BALL SUPPLY SENSOR ERROR [E.71]
▶SOLUTION :BALL SUPPLY MOTOR ERROR [E.71]
1 HOW TO TEST :TEST MODE → BALL SUPPLY TEST → SELECT button → SHOOTING button
2 Check the jamming ball supply rail ,Check for BKT jams during belt drive ( P1 )
3 Check connection of motor connector ( P2 )
4 Check assembly status of motor ( P3 )
5
Check the dc voltage ( MAIN PCB / CN16 )
: PIN 1 : Over 11V , PIN 2 : GND
6 Replace MOTOR
7 Replace MAIN PCB
▶SOLUTION : BALL SUPPLY SENSOR ERROR [E.71]
1 HOW TO TEST :TEST MODE → BALL SUPPLY TEST → SELECT button → SHOOTING button
: Third digit of the PLAY FND - Detected Sensor : flicker " _ " / Non-Detected sensor : " 0 "
2 Check connection of sensor connector ( P4 )
3 Check assembly status of sensor , Check position of sensor bracket ( Center ) ( P5 )
4 Check the dc voltage ( SENSOR PCB ) : PIN 1 : over 4.5V , PIN 2 : below 0.5V , PIN 4 : GND ,
PIN 3 : Detected Sensor over 4.5V / Non-detected sensor below 0.4V
Check the dc voltage ( MAIN PCB / CN16 )
: PIN 3 : Over 4.5V , PIN 4 : Below 0.5V , PIN 6 : GND
7 Replace MAIN PCB
