TW
OPTICAL FIBER PHOTOELECTRIC SENSOR
(DIGITAL LEVEL INDICATION)
INSTRUCTION SHEET
1) Do not use the sensor in explosive or ignition gas.
2) Never disassemble, repair nor tamper with the sensor.
3) Do not apply excess voltage and current over rating.
4) Do not wire improperly such as reversing polarity.
5) Connect the load correctly.
6) Do not short-circuit the load.
1) There are some cases where the photoelectric switch cable is unavoidably wired in
a tube or duct together with a noisy or power line. This causes an induction,
possibly resulting in malfunction or damage. In principal, the cable should be
wired separately or shielded.
2) For extending wires, use a cable 0.3mm
2
min.,and 100m max. in length. When
using the cable as a Korea’s S-mark certified product,use the cable of less than
10m in length.
3) Do not exceed the following force values applied to the cable.
Tencile:80N max., torque:0.1N
・
m max., Pressure: 20N max., flexure: 3kg max.
4)Operation after the power is turned on.
The E3X-DA will begin sensing no later than 200ms after the power is turned
on. If the load and the E3X-DA connect to different power supply, the E3X-DA
must be always turned on first.
5)EEPROM write errors
If a write error (output indicator : flashing) occurs during teaching due to a power
failure or noise from static electricity, execute the teaching again using the button
on the main unit.
6)When using the sensor, protective cover must be put on the sensor.

2. 1 Teaching the automatic sensitvity level.
(1) Select the channel to set.
(2) Set the mode selector to the SET position.
Hold down the Key for 3
seconds or longer.
(The incident light amount
is digitally displayed.)
Make sure the red indicators light up
first and then the green indicators light
up instead. Go to the RUN mode. (After
the green indicators light up about 1
second, the incident light amount gets
digitally displayed again.)
