NSK Surgic Pro+ - Protection Circuit; Error Code & Troubleshooting

8. Error Code & Troubleshooting
If an operational problem occurs the display will show an Error Code allowing immediate problem diagnosis.
When an error occurs, there will be a beep and an Error Code will appear on the LCD. The Error Code will blink until
the error is alleviated. The USB REC LCD will go on for about 10 seconds.
7. Protection Circuit
An electronic circuit breaker automatically functions to protect the motor and the Control Unit if the motor is ever
overloaded. Power supply to the motor will automatically be terminated an Error code will be displayed on the Control
Unit.
When torque exceeds the set figures, “SAFE” will appear on the LCD, and the device will stop.
*Resetting the Protection Circuit
To reset the Protection Circuit, release and then depress the Speed Control Pedal.

Request repair.
Electrical contact may be insufficient.
Securely re-connect the Motor Cord.
When an error cannot be eliminated, request
repair.
Request repair.
Make sure to put a Protection Plug when
Thermo-disinfecting it.
Allow it to cool down before use.
Since heat is sufficiently radiated, periphery of
the main Control Unit should be
well-ventilated wherever possible. When an
error cannot be eliminated, request repair.
When rotation and stop are repeated in
short frequencies, a circuit may be activated
which limits acceleration at start. Wait a few
seconds and then use.
When an error cannot be eliminated, request
repair.
The chuck may be opened, or may not be
sufficiently closed. Securely close the chuck.
When an error cannot be eliminated, request
repair.
