1
Make sure that NCS SENSOR CLEANING screen [screen 4.8] is
displayed.
- When it is not ;
See the section 1-1-1 of this chapter, [Calling up the NCS
SENSOR CLEANING screen [screen 4.8]].
2
Open the splash cover.
- The interlock system is actuated.
3
Remove the cover [H] and [I]. Then store it sufficiently away
from the working area.
- For the cover removal procedures,
see the section B-2-1, [Removing the Machine Outer Cover
and Status Indicator] of Installation Manual.

4
Turn the sensitivity regulation dial of the amplifier with the
amplifier adjustment driver so that the voltage level reading on
the NCS SENSOR CLEANING screen [screen 4.8] comes within
a range of 100 ± 2% (4.90 to 5.10 V).
- Turn the sensitivity regulation dial clockwise to increase the
sensitivity.

- If the sensor voltage level does not come within the range of
100 ± 2% (4.90 to 5.10 V) even after setting the sensitivity
regulation dial at MAX, the fiber may be bent or the amplifier is
broken down.
In such cases, contact your nearest DISCO office.
5
Reinstall the cover [H] and [I].

Procedures for completion of cleaning the non-contact setup sensor
Step No. Do This
(Continued from the previous section)
1
Close the splash cover.
2
Press the <System Initial> button to effect system initialization.
3
Press the <Spindle> button to rotate the spindle.
4
Press the <Cut Water> button to turn ON the wheel coolant water
supply.
5
Idle the machine for 10 minutes.
6
Carry out the sensor calibration setup.
- For the procedures of the sensor calibration setup,
see B-7, [Setup] of Operation manual.
If errors or height variations frequently occur
If setup-related errors or height variations frequently occur immediately after
setup, even after repeating to clean the sensor detection surface or adjusting
the amplifier, the problem is attributable to a bent fiber or defective amplifier.
When this type of trouble occurs, contact your nearest DISCO office.
The following setup-related errors might occur.
