Display
Foot Air Calibration:
This function enables
you to use the maximum
speed 40,000 min-1, even
though the air pressure
of the dental unit is not
high enough, by setting
air pressures for "motor
startup speed" and
"maximum motor speed".
Delay time for the light:
This function sets the delay time for the white illumination
lamp going off after the motor stops.
The notifying sound :
This function sets the volume for the operation tone
when a key is pressed.
Contra-Restriction:
This function automatically slows down and stops the
rotation of the motor when the checking result through
Contra-Check is either "OIL" or "NG". The motor cannot
be activated when the checking result is "NG" blinking
which shows the status of handpiece defect. (Refer
to "4-4 Contra-Check Function" and "4-8 Overheat
Prevention")
Contra-SAFE:
This is a function to stop the rotation of the motor when
continuous motor high-load current is detected with a 1:5
increasing handpiece.*
In this mode, there are selectable three sensitivity levels:
Fast, standard and Slow and the "Fast" setting offers
the most sensitive response. (Refer to "4-8 Overheat
Prevention")
*Use NSK handpieces : the model of Z95L, Z85L, X95EX,
X95L, X95, M95L, M95, X85L, X85 of 1:5 Gear Ratio.
Function item
Air pressure for motor
startup speed:
This is the lower limit
of the air pressure at
which the motor starts to
operate.
Air pressure for maximum
motor speed:
This is the upper limit of
the air pressure at which
the motor will run at its
maximum speed.
This value can be set
only when there is an
air supply at a pressure
of equal or higher than
1.5bar.
