Adjustment and Operation of the Linear Sensor Controller
Control panel of the Linear Sensor Controller
The control panel consists of two switches (MODE and MONITOR),
two adjusters (CENTER and WIDTH) and four indicators (POWER,
PASS, NG, INHIBIT) for monitoring.
By adjusting the settings of the Linear Sensor Controller and com-
pensating for the position of the LED Displacement Sensor, the size
of the object of standard dimensions is registered with the Linear
Sensor Controller. With the object of standard dimensions, operate
the LED Displacement Sensor as follows:
1. Set the MODE switch to NORMAL.
2. Turn the WIDTH adjuster counterclockwise to the MIN
position.
3. Turn the CENTER adjuster clockwise or counterclockwise
and set the adjuster to the position where the PASS indicator
is lit. If the PASS indicator is lit for a wide range of positions,
set the adjuster in the middle of the range. If the PASS
indicator does not light with the CENTER adjuster in any
position, turn the WIDTH adjuster clockwise slightly.
An object of threshold dimensions or a multimeter can be used to
determine the tolerance (use the object where possible).
Determining Settings Using an Object
1. Prepare an object of threshold dimensions (an object with the
allowable upper threshold dimensions or with the allowable
lower threshold dimensions) to be detected by the LED
Displacement Sensor.
2. Set the MODE switch to NORMAL.
3. Turn the WIDTH adjuster counterclockwise to the MIN
position. The NG indicator will light.
4. Turn the WIDTH adjuster clockwise slowly to the position
where the NG indicator turns OFF. The PASS indicator will
light.
Determining Settings Using a Multimeter
Determine the absolute tolerance, A (in mm), and obtain the voltage
V
x
(V) as follows (example for tolerance of
"
0.5 mm):
1. Set the MONITOR switch to WIDTH.
2. Check the voltage of monitor terminals 10 (positive voltage
output) and 8 (negative voltage output) of the Linear Sensor
Controller with the multimeter in the 10-VDC or 5-VDC range.
3. Turn the WIDTH adjuster clockwise or counterclockwise to
the position where the voltage reaches V
x
(obtained from the
above formula).
Set the MODE switch to TRIG as follows:
1. Set the MODE switch to TRIG.
2. Set the MONITOR switch to INPUT or OFFSET (RUN).
3. Turn off the power and wire the output terminals (No. 4, 5, and
6).
