## Operation
## J **FUZZY LOGIC MUTUAL INTERFERENCE PREVENTION FUNCTION**
## **(FOR E3S-CR** jj **AND E3S-CD** jj **ONLY)**
If photoelectric sensors are installed side by side, each Sensor may be influenced (or malfunction) by the light emitted from the other sensors. This is known as mutual interference.
The fuzzy logic mutual interference prevention function of the E3S-C enables the E3S-C to monitor light interference over a certainperiodof time. BeforetheE3S-Cstarts emittinglight, theE3S-C retrieves the intensity and frequency of surrounding light interferenceasdata.Usingthisdata,theE3S-Ccalculates,withfuzzyinference, therisk of theE3S-Cmalfunctioningandcontrols the timingof the E3S-C’s light emission.
When the risk is low, the E3S-C waits until there is no light interference and emits light.

Unlike conventional photoelectric sensors, the variation in the sensitivity among several E3S-C photoelectric sensors is minimal. This means the sensitivity can be adjusted on only a single photoelectric sensor, and then the adjusters on the other E3S-C photoelectric sensors can be set to the same scale position. There should be no need to adjust the sensitivity of each photoelectric sensor individually.

## Precautions
## J **CONNECTION**
If the input/output lines of the photoelectric sensor are placed in the sameconduit orduct as powerlinesorhigh-voltagelines, thephotoelectric sensor could be induced to malfunction, or be damaged, by the electrical noise. Either separate the wiring, or use shielded lines as input/output lines to the photoelectric sensor.
## J **WATER RESISTANCE**
To ensure the water resistance of the E3S-C, tighten the screws of the operation panel cover to a torque of 3.5 to 5.5 kgf S cm (0.34 N S m to 0.54 N S m).
The cord connected to the E3S-C can be extended up to 100 m providedthat thediameterofeachwireof thecordis0.3mm[2] minimum.
## J **POWER SUPPLY**
If the standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal, on the power supply, must be grounded. If this is not done the E3S-C may malfunction, due to the switching noise of the power supply.
If an inverter motor or servomotor is used with the E3S-C, the frame ground (FG) terminal and the ground (G) terminal, on the motor, must be grounded, otherwise the E3S-C may malfunction.
## Installation
## J **MOUNTING**
Use M4 screws to mount the E3S-C. The tightening torque of each screw must be 12 kgf S m (1.18 N S m) maximum.
## J **DIRECT MOUNTING**
Mount the E3S-C as shown in the following illustrations.
