Q&A
Question
Can calculations be performed with ZX-E
and ZX-T series Smart Sensors?
Can the ZX-SF11 Interface Unit used with
the ZX-LDA11/LDA41 or ZX-E-series
Smart Sensors be used with the ZX-
LDA11-N/LDA41-N Smart Sensors?
Why does an error occur and settings
cannot be made when teaching or directly
inputting threshold values?
When scaling is executed, an error
appears on the sub-display and settings
cannot be made.
When monitor focus is executed, why
does an error appear on the sub-display
and the settings cannot be made?
When entering the thickness for thickness
calculation, why does an error appear on
the sub-display and the settings cannot be
made?
Can calculations be performed with 3 or
more Amplifier Units?
Can calculations be performed when
Sensor Heads with different measurement
ranges are connected to 2 Amplifier
Units?
How many Amplifier Units can be
connected and communicated with ZX-
SF11?
Is warm-up operation still required even if
LD-OFF input is cancelled?
Contact your OMRON representative.
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 Monitor.)j
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.88
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 rated
measurement range.
p.72
Monitor focus settings cannot be made when the distance between the
two specified points is not 1% or more of the rated measurement range.
p.95
The present value is outside the measurement range.Place the sensing
object within the measurement range and then enter the thickness.
p.54
In the case of ZX-LDA11-N/LDA41-N Amplifier Units, calculations can
be performed with up to eight units (CH1 with one of CH2 to CH8). (With
the ZX-LDA11/LDA41 Amplifier Units, calculations can be performed
with up to two units. Calculations cannot be performed if ZX-LDA and
ZX-LDA are used together.)
Yes if the Sensor Heads are the same type (Reflective type or
Through-beam type). However, this is not true in the case of ZX-LDA11/
LDA41. Calculations cannot be performed if ZX-LDA and ZX-LDA are
used together.)
In the case of ZX-LDA11-N/LDA41-N Amplifier Units, up to five units can
be connected. (In the case of the old models ZX-LDA11/LDA41, up to
two units can be connected. Communications cannot be performed if
ZX-LDA and ZX-LDA are used together.)
Yes. As when the power is turned ON, warm-up operation must be
performed for about 10 minutes.
