Mounting Instructions
Installation environment
• Do not use the unit in places where it may receive excessive
shocks. Otherwise the inside of the unit may be damaged or the
unit may become unable to produce normal output signals.
• Locate the measuring unit at least 10 cm away from a strong
magnetic source. (Th
e measuring unit must not be used in
magnetic fi elds exceeding 5 mT.)
• Do not place the measuring unit where it is exposed to splash of
water or oil.
Mounting
• Be sure to turn off the power switch of the digital tolerance
indicator before connecting or disconnecting the output cable.
• When attaching and removing the feeler, use the supplied
spanner. Be careful not to apply torque exceeding 0.1 N·m to the
spindle. Th
is could lead to a breakdown.
To prevent the feeler from becoming loose, it is recommended
to either attach the supplied spring washer (nominal size: 2.5)
or use a screw lock. (tightening torque reference value: 0.05–
0.06 N·m)

• Fix the cable in a suitable position to prevent possible cable
breakage. Never handle the cable by forcibly pulling or bending
it. (Inside bend radius 50 mm or more)
• Th
e measuring accuracy depends on the mounting parallelism.
Adjust the squareness to the measuring surface or the parallelism
to the movement to within 0.02 mm/14 mm.
• Aft er the stem is secured, do not apply force in the rotational
direction. Th
is could cause a failure.
• Th
e measuring unit comprises ball bearings. Th
erefore, chucking
the stem of the measuring unit too tightly when mounting may
damage the spindle and prevent its smooth motion.
• Attach the stem by tightening a screw into the slot as shown
in Fig. 2. Never attach by screw threading in the
φ
8 mm hole
vertical direction, pressing the stem, and then tightening with a
screw. Th
is could result in poor sliding and low precision.
• Be absolutely sure to chuck the stem part when mounting the
measuring unit.
• Using Fig. 2 as a reference, select which holder to have ready at
the mounting side.

• When mounting onto a machine, use of the Flange Adaptor
DZ830F (optional accessory) is recommended for preventing
damage to the measuring unit due to over-tightening.
• For the mounting procedure, please refer to the Instruction
Manual supplied with the DZ830F.

Maintenance
• Calibration is recommended every year.
• An anti-dust bellows available as an optional accessory can
be mounted to the spindle part of this unit. Organic solvents,
ozone, ultraviolet rays, and other adverse conditions in the
ambient atmosphere can cause rapid deterioration of the anti-
dust bellows. When using in these environments, replace anti-
dust bellows periodically (every six months to one year).
When providing an IP67 protection grade
• Please use the optional DZ830BL bellows set.

Troubleshooting
Th
e operating status of the measuring unit can be checked using the LED
indicator.

Remedial action
Lights in blue.
The power is turned on. Normal operation
is now performed. The reference point has
been detected.
-
Blinks in blue.
The power is turned on.
The reference point standby status is
established or the reference point is being
detected.
When the reference point is used, turn on the power with the spindle
extended as far as possible, and then move the spindle 1.5 mm or more.
When the power is turned on with the spindle stopped near the reference
point position, it may not be possible to detect the reference point or the
reference point may shift.
When the reference point will not be used, set the reference point use setting
to OFF at the digital tolerance indicator.
Blinks in red.
The signal level of the measuring unit is
abnormal.
After dealing with the factor suspected to be responsible for the alarm, turn
the power back on.
If the same symptoms persist even after the power has been turned back
on, the measuring unit or digital tolerance indicator might be malfunctioned.
Lights in red.
The maximum response speed has been
exceeded. The signal level of the measuring
unit is abnormal. Serial communication
trouble has occurred. Normal operation
cannot be performed due to the eff ects
such as external noise etc.
