Correct Use

E3G-R/MR
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.
Model Tensile strength
E3G-R13-G
50 N max.
E3G-MR19(T)-G
E3G-R17-G 10 N max.
● 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.

Note: If the operation level is set to the stable operation range, the E3G will operate with
the highest reliability and without being influenced by temperature change, voltage
fluctuation, dust, or setting change.

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.

50 N max.
E3G-ML79(T)-G
E3G-L77 10 N max.
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.
E3G-M#(T)-G
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.
