This is position A. Background Object Remove the detected object and turn the adjustment knob clockwise until the LIGHT indicator (orange) lights. This is position B. Then turn the adjustment knob counterclockwise until the LIGHT indicator (orange) goes out. This is position C. Set the adjustment to halfway between A and C. Confirm that the STAB indicator (green) remains lit both with the detected object present and not present. If the STAB indicator does not remain lit, reconsider the detection method to enable stable operation.

The cord connected to the Sensor can be extended up to 100 m provided that the diameter of each wire of the cord is 0.3 mm2 minimum. A maximum of 100 ms is required from the time power is turned on until the E3S-CL is able to detect objects. If power is supplied to the loads and the E3S-CL from different sources, turn on power to the E3S-CL first. H H POWER SUPPLY If a standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal must be grounded, otherwise the Sensor may malfunction due to the switching noise of the power supply. H WATER RESISTANCE To ensure the water resistance of the E3S-CL, tighten the screws of the operation panel cover to a torque of 2.5 to 5.0 kgf S cm (0.25 N S m to 0.49 N S m). OIL AND CHEMICAL RESISTANCE (E3S-CL2) Oil Kinematic Viscosity (mm2/s (cst)) at 40!C pH Lubricating oil 2.02 --- Water insoluble machining g oil 10 min. and less than 50 Less than 10 Water soluble machining g oil --- 7 to 9.5 7 to 9.9 7 to 9.2 7 to 9.8 Note: 1. The E3S-CL2 maintained a minimum insulation resistance of 100 M$ after the E3S-CL2 was dipped in all the above oils at a temperature of 50!C for 240 hours. 2. When using the E3S-CL2 in a place where an oil other than the ones listed above is sprayed on the E3S-CL2, refer to the above kinematic viscosity and ph values. The location may be suitable for the E3S-CL2 if the kinematic viscosity and pH values of the oil are close to the above kinematic viscosity and pH values, but make sure that the oil does not contain any additive that may have a negative influence on the E3S-CL2. H CABLE The E3S-CL2 uses an oil-resistant cord to ensure oil resistivity. Do not allow the cable to be repeatedly bent during application. Do not allow the cable to be bent to a radius of less than 25 mm. H MALFUNCTIONING If an inverter motor or servomotor is used with the E3S-CL, the frame ground (FG) terminal and the ground (G) terminal must be grounded, otherwise the Sensor may malfunction. 10 E3S-CL H E3S-CL MOUNTING Mounting Direction Mount the Sensor so that the detection face runs parallel to the surface of the object being detected and not at an angle (see below). Mount the Sensor so that it is not aligned with the direction of movement of the detected object, as shown below. Mount the Sensor so that it is not aligned with extreme changes in color or materials, as shown below. Correct Incorrect Detection face Surface of object detected Direction of movement Direction of movement If detecting a shiny object, mount the Sensor so that the detection face is at an angle of between 5_ and 10_ of the surface of the object being detected. Check to be sure that there is no interference from the background (see below). Incorrect Correct Detected object Detected object Direction of movement Detected object Direction of movement Shiny object If stable operation is not possible near a mirror surface, mount the Sensor at an angle as shown below, and separate the Sensor as far as possible from the mirror surface. Detected object Mirror surface Mount the Sensor so that sunlight, fluorescent light, incandescent light, or other strong sources of light do not enter the directional angle of the Sensor. Precautions When mounting the Sensor, do not hit the Sensor with a hammer, or any other object. This will cause the Sensor to lose its watertightness. Use M4 screws to mount the Sensor. The tightening torque of each screw must be 12 kgf S m (1.18 N S m) maximum. Direct Mounting Mount the Sensor as shown in the following illustration. Two, 4.5 dia. through holes Two, M3 M4 hole M4 hole !
