Standard Photoelectric Sensors
Zone teaching
Note: Perform zone teaching with the background.
Maximum distance setting (in normal mode)
If you want to set the maximum distance of the sensor, set a
maximum distance as depicted in the following procedure.
Precautions
Design
Power Supply
A full-wave rectification power supply can be used with the
E3G-MR19(T)-G.
Wiring Considerations
The tensile strength of the cable during operation should not
exceed the values shown below.
●
For adjustment
Display
• The following graphs indicate the status of each operation
level.
• Set the E3G so that it will work within the stable operation
range.
Design
Power Supply
A full-wave rectification power supply can be used with the
E3G-ML79(T)-G.
Wiring Considerations
The tensile strength of the cable during operation should not
exceed the values shown below.
Miscellaneous
EEPROM Write Error
If a write error occurs (operation indicator flickers) due to pow-
er-off, static electricity or other noise in the teaching mode,
perform teaching again.
Wiring Considerations
• The cable with an external diameter of 6 to 8 mm is recom-
mended.
• Securely tighten the cover to maintain water resistance and
dust resistance. The thread size of the conduit socket is PG
13.5
• Do not tighten with the cable caught by the terminal protec-
tion cover. Otherwise, the water-resistant structure and like
cannot be maintained.
