operation procedure
●
If you change settings, press the SET key before you turn the power
OFF. Otherwise your changes will be lost.
● With FX-502□, press the MODE key for 3 seconds to switch from
sensing output 1 to sensing output 2.
When you turn the power ON, the amplifier is in RUN mode. Press the
MODE key (indicated by black arrow in the illustrations below) to switch
from one mode to the next.
RUN mode
●
Displays the threshold value in green
and the incident light intensity in red.
● Used for teaching, making fine
adjustments to the threshold values
(see page 5), and activating the
key lock function (see page 5).
Sensing output operation mode
●
Select either Light‑ON or Dark‑ON.
The default setting is
(Light‑ON).
●
Refer to sensing output operation
mode on page 5 for details.
CUSTOM mode
●
Displays one of the three settings
available in CUSTOM mode (re‑
sponse time, emission power, hyster‑
esis). The default setting is
(response time).
●
Refer to CUSTOM mode on page
5 for details.
PRO mode
●
Used for advanced settings.
●
Refer to PRO mode on page 6
for details.

teaching
●
Please note that if the threshold values are very close to each other,
objects may not be detected reliably.
●
For teaching in Window Comparator mode or Hysteresis mode,
you need to set the shift amount in PRO mode first. For the setting
procedure, refer to the “PRO MODE OPERATION MANUAL” (only
available in English).
●
If you use 1‑point teaching, set the shift amount (the initial value is
10% or 100) in PRO mode.
Teaching is performed in RUN mode. There are different teaching methods
available. Which teaching method is recommended depends on the sensor
type and whether the sensing object is present or not present or moving.
sensing condition
recommended teaching
method
Sensing object is present and easily
detectable.
2‑point teaching
Sensing object is very small.
Other objects are in the background.
Limit teaching
Production line cannot be stopped and
sensing object is moving
Auto teaching
All teaching methods are available for the thru-beam and the reflective type.
2-point teaching
The basic teaching method when the sensing object is present is

limit teaching
When the sensing object is small or there are objects in the background,
use this teaching method. Both the thru-beam type and the reflective type
can be used. The procedure only shows the thru‑beam type.
Sensing object is present
Sensing object is not present
1. Press the SET key
when the sensing
object is present or
not present.
2. Press the UP key to
shift the threshold
level to a high level
(low sensitivity) or
press the DOWN key
to shift the threshold
level to a low level
(high sensitivity).
Display when stable sens‑
ing is possible.
Display when stable sens‑
ing is not possible.
Full auto teaching
When the sensing object is moving, use this
teaching method. Both the thru‑beam type
and the reflective type can be used. The pro
‑
cedure only shows the thru‑beam type.
1. Press and hold the SET key for a long time
2. Run the sensing object on the production
line and hold down the SET key.
3. The display shows
in green. When
the sensing object has passed through,
release the SET key.
