Care and maintenance
7
!1!0
CAUTION
Because the handpiece AUTOMATICALLY starts to run, any bur must be removed from the handpiece before beginning the calibration process. Leaving a bur in the handpiece may cause harm to the operator. Care should be exercised not to ever add any load to a handpiece during calibration, because an incorrect diagnosis would result in incorrect torque control.
If “FAIL” is displayed on the liquid crystal panel, check the mounting of
each part and operate again. If “FAIL” is still displayed, contact your dealer.
CAUTION
This equipment is optimized to obtain the highest accuracy at a gear ratio of 1/20. When using another gear ratio, please note that the accuracy decreases with an increase in the ratio relative to 1/20.
Erroneous memory. Memory failure.
Extended use under heavy load. Short circuit in the power cord. Short circuit in the motor cord.
Main power cord failure.
Micromotor sensor failure (Hall IC). Micromotor cord failure. Signal line failure.
Overheating by extended use under heavy load. Operation of the unit under an extremely high temperature.
Abnormal voltage generated in the start / stop switch circuit. Failure in the start / stop switch circuit.
Handpiece attachment failure. Micromotor failure.
When the motor stops for more than 5 seconds after reaching the torque upper limit.
Cause of Error
Request repair.
Electrical contact may be insufficient. Securely re-connect the motor cord. When an error cannot be eliminated, request repair.
Allow it to cool down before use. In order that heat is sufficiently radiated, periphery of the main 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.
This is not a failure. It stops for safety reasons. When the error is reset, this can be used as it is.
