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

Response time is the time from when the Sensor measures a distance to when the value is output (either as linear output or judgement output).
The response time changes depending on the settings for the number of samples to average, calcu-lations, and mutual interference prevention.
Measured value
The measured value is the measurement result displayed on the main display of the Amplifier Unit in RUN and T modes.
The measured value is the value after all set processing has been completed, e.g., linearity adjust-ment, number of samples to average, scaling, calculations, hold, and previous value comparison.
p. 51
Present value The present value is the current measurement result for the target Amplifier Unit.
Some set processing, such as linearity adjustment, number of samples to average, and scaling, have been completed for the current measured value, but calculation, hold, and previous value compari-son settings are not reflected.
Press the LEFT or RIGHT Key in RUN mode to display the present value on the sub-display.
p. 51
Linearity The linearity is given as the error in an ideal straight line displacement output when measuring the standard sensing object. The linearity shows how closely the linear output maintains a linear rela-tionship to the displacement of the sensing (i.e., it shows the accuracy of the linear output).
More precise linearity can be obtained with the ZX-E Smart Sensors by performing linearity adjust-ment.
p. 54
Linear output The linear output is analog data output from the linear output line. Either a current or voltage output can be selected.
The linear output is made based on the display value and monitor focus settings.
The actual value output (the output value) can be displayed on the sub-display by pressing the LEFT or RIGHT Key in RUN mode.
p. 51
Judgement outputs
“Judgement outputs” is a general term for the HIGH, PASS, and LOW outputs. The judgement out-puts are made in RUN and T mode based on the display values and the threshold, hysteresis width, and timer settings. The judgement output is held while judgement output hold input is ON.
Smart Monitor
The Smart Monitor is software (sold separately) for Windows 98 or 2000. Use Smart Monitor soft-ware to communicate, via an Interface Unit, with ZX-E-series Smart Sensors. This means that mea-surement settings can be made from personal computers, settings data saved, meamea-surement results displayed as graphs, and data logged.
Smart Monitor version 2 or later must be used with ZX-E-series Smart Sensors.

Measure-ment dis-tance
The measurement distance is the range (distance) that measurement is possible for the connected Sensor Head.

Sampling period
Sampling period is the time over which the sensing object is measured when the hold function is being used.
The sampling period is determined by the trigger mode and the delay time.
