Q&A
Question
Answer
Can the cable between Sensor Heads and the
Preamplifiers be extended?
No. If the cable is extended, measurement precision is lost.
Can calculations be performed with ZX-L-series
Smart Sensors (Laser Type) ?
No. The ZX-E-series Smart Sensors (Inductive Displacement
Type) and ZX-L-series Smart Sensors (Laser Type) are not com-
patible.
Can the ZX-SF11 Interface Unit used with the
ZX-L-series Smart Sensors (Laser Type) be
used with the ZX-E-series Smart Sensors
(Inductive Displacement Type)?
Yes, if the Interface Unit is version 2.0 or later. If the Interface Unit
is an earlier version, contact your OMRON representative.
(The Interface Unit version can be checked with the Smart Moni-
tor.)
Can the ZX-CAL Calculation Unit used with the
ZX-L-series Smart Sensors (Laser Type) be
used with the ZX-E-series Smart Sensors
(Inductive Displacement Type)?
Yes. However, only two Amplifier Units can be connected.
Why does an error occur and settings cannot be
made when teaching or directly inputting thresh-
old values?
Threshold values cannot be set using teaching or by direct input if
the following condition is not met:
• HIGH threshold value
−
LOW threshold value
>
hysteresis width
p. 97
When scaling is executed, an error appears on
the sub-display and settings cannot be made.
Scaling cannot be set for one of the following reasons:
• Scaling has been attempted when the measured value is
outside the measurement distance range.
• When two-point scaling has been executed, the distance
between the measured values for the two points is not 1% or
more of the measurement distance.
p. 95
When monitor focus is executed, why does an
error appear on the sub-display and the settings
cannot be made?
Monitor focus settings cannot be made when the distance
between the two specified points is not 1% or more of the mea-
surement distance.
p. 103
When entering the thickness for thickness calcu-
lation, why does an error appear on the sub-dis-
play and the settings cannot be made?
The present value is outside the measurement distance. Place
the sensing object within the measurement distance range and
then enter the thickness.
p. 74
Can calculations be performed with 3 or more
Amplifier Units?
Contact your OMRON representative.
Can calculations be performed when Sensor
Heads with different measurement distances are
connected to 2 Amplifier Units?
Yes, if both Sensors are ZX-E-series Smart Sensors (Inductive
Displacement Type).
The sensing object is made of copper. What
material should I select for linearity adjustment?
Use the default, aluminum (AL).
When linearity adjustment is executed, why does
an error occur and linearity is not adjusted?
Occasionally linearity cannot be adjusted due to the surface sta-
tus of the sensing object used, e.g., the surface is rough or has
been processed. Initialize the linearity adjustment data and use
the default settings.
The main display does not change to zero even
when sensing objects are in contact with the
Sensor Head.
Sometimes the status of the sensing object surface, e.g., the sur-
face is rough or has been processed, prevents the display from
changing to zero even when the sensing objects are in contact
when the default linearity adjustment values are used. Either exe-
cute linearity adjustment or execute a zero reset first.
