Sub display (Lower level)
The sub display switches with each push of the W or X button. According to the
type of displayed value selected, the sub display identification indicator will show
one of the following: [R.V. / ANALOG / HI / LO / SHIFT]
When the amplifier is turned on for the first time after the sensor head is connected,
the initial setting display appears. Make the initial setting according to the following
procedure as this is necessary for both the main unit and the expansion units when
units are added.
1
Select the judgment output and check output
polarity with the S/T button, and press the
[MODE] button.
2
Press the S/T button to select the analog
output method and press the [MODE] button.
After the setting is complete, [GPF] blinks several times on the sub display and
changes to the main screen.
3
Carry out
“Adjusting the beam axis” (page 6) and
"Reference Light Registration (Gain Adjustment)" (Page 7).
Make other settings as necessary.
Adjust the laser beam’s axis.
1
Fix the receiver so that the transmitter and receiver are on the
same line.
2
With no object set in the detection area, move the transmitter
and fix it where the display value is the largest.
Beam axis alignment function
The IB series has a beam axis alignment function which makes it easy to adjust the
beam axis.
The beam axis can be adjusted easily with the help of the amplifier unit's display
and sensor head laser emission warning indicator.
1
Press the W/X buttons on the main screen simultaneously for 2
seconds, and display the received light on the sub display (lower
level).
2
With no object in the detection area, move the transmitter and
mount the transmitter and receiver so that the displayed
received light is the largest.
When the beam axis is aligned, the value on
the sub display (lower level) will increase. Fix
the units where the value is the largest when
possible.
At this time, the laser emission warning
indicator on the sensor head will turn off or
blink. The indicator's flashing cycle quickens
as the received light increases.
Adjust the beam axis together with the
incoming light level on the sub display (lower
level).
* The blinking cycle changes in stages. The faster the indicator blinks, the more
accurate the beam axis alignment is.
3
The main screen will reappear when a random button on the
amplifier unit is pressed.
R.V. (internal measurement value)
The R.V. (internal measurement value) is displayed. This
displayed value is not held.
Analog output (The analog output will only be displayed for
the main unit and only when it is enabled.)
The voltage value (unit: V) or current value (unit: mA) of the
analog output is displayed.
"Operation When the Power Is Turned On for the First Time" (Page 6)
"Initial Reset (Initialize)" (Page 8)
HIGH setting value
The upper limit of the acceptable range (tolerance setting
value) for the object that is being measured is displayed.
Also, the setting value can be changed. If the P.V. (judgment
value) exceeds the value set here, the HIGH output signal
will be sent.
"Setting the Tolerance Setting Value" (Page 7)
LOW setting value
The lower limit of the acceptable range (tolerance setting
value) for the object that is being measured is displayed.
Also, the setting value can be changed. If the P.V. (judgment
value) falls below the value set here, the LOW output signal
will be sent.
"Setting the Tolerance Setting Value" (Page 7)
Shift target value
When the zero shift button is pressed or the zero shift input is
set to ON, the R.V. (internal measurement value) will be
matched to the value set here.

Value)" (Page 7)

Adjusting the Beam Axis
The beam axis does not need to be adjusted if the base of the
