## Operation
## **FUZZY LOGIC MUTUAL INTERFERENCE PREVENTION FUNCTION**
## **(FOR E3S-CR AND E3S-CD 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 certain period of time. Before the E3S-C starts emitting light, the E3S-C retrieves the intensity and frequency of surrounding light interference as data. Using this data, the E3S-C calculates, with fuzzy inference, the risk of the E3S-C malfunctioning and controls the timing of the E3S-C’s light emission.
When the risk is low, the E3S-C waits until there is no light interference and emits light.

When the risk is high, the E3S-C emits light between each light interference moment.

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
## ~~||~~ **CONNECTION WATER RESISTANCE**
If the input/output lines of the photoelectric sensor are placed in the same conduit or duct as power lines or high-voltage lines, the photoelectric 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.
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 cm (0.34 N m to 0.54 N m).
The cord connected to the E3S-C can be extended up to 100 m provided that the diameter of each wire of the cord is 0.3 mm[2] minimum.
## | **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
## | **MOUNTING** |
## **OPTICAL AXIS OF THROUGH-BEAM SENSOR**
Use M4 screws to mount the E3S-C. The tightening torque of each screw must be 12 kgf m (1.18 N m) maximum. e . **DIRECT MOUNTING**
The E3S-C through-beam models incorporate two lenses, one of which will be used as shown in the following illustration. When using a slit, the slit must be on the side where the lens is located.
Mount the E3S-C as shown in the following illustrations.
