## Safety Precautions 

## **Refer to** _**Warranty and Limitations of Liability**_ **.** 

## **WARNING** 

**This product is not designed or rated for ensuring safety of persons. Do not use it for such purpose.** 

**Do not apply AC power to the E3T, otherwise the E3T may rupture.** 

## **Precautions for Correct Use** 

Do not use the product in atmospheres or environments that exceed product ratings. 

## Wiring 

The maximum power supply voltage is 26.4 VDC. Before turning the power ON, make sure that the power supply voltage be not more than maximum voltage. 

## Adjusting 

## **Indicators** 

- The following graphs indicate the status of each operating level. 

- Be sure to use the E3T within the stable operating range. 

**==> picture [197 x 120] intentionally omitted <==**

**----- Start of picture text -----**<br>

- If the E3T fs operating level is set to the stable operation range, the E3T will be in most reliable operation without being influenced by temperature change, voltage fluctuation, dust, or setting change. If the operating level cannot be set to the stable operation range, pay attention to environmental changes while operating the E3T. 

## **Load short-circuit protection** 

The E3T incorporates a load short-circuit protection function. If the load short-circuits, the output of the E3T will be turned OFF. Then, recheck the wiring and turn on the E3T again to reset the load shortcircuit protection function. The load short-circuit protection function will work if there is a current flow that is 1.5 times larger than the rated load current. When using a capacitance load, be sure that the inrush current will not exceed 1.5 times larger than the rated current. 

## **E3T-CD@@ Sensitivity Adjustment** 

Use the special screwdriver that is provided with the Sensor to adjust the sensitivity. Do not exceed 0.8 N·m when turning the adjuster. 

## Others 

## **Do not install the E3T in the following locations.** 

- Locations subject to excessive dust or dirt 

- Locations subject to direct sunlight 

## Mounting 

When mounting the Sensor, never strike it with a heavy object, such as a hammer. Doing so may reduce its watertight properties. Use screws with spring, flat, or toothed washers to secure the Sensor. Tightening Torque 

Small Cylindrical Sensors: 1 N·m max 

- Locations subject to corrosive gas 

- Locations subject to contact with organic solvents 

- Locations subject to vibration and shock 

- Locations subject to contact with water, oil, or chemicals 

- Locations subject to high humidities that might result in condensation 

## **Mounting the Sensor on Moving Parts** 

Consider models that use break B resistant cables (e.g., Robotics Cables) if the Sensor will be mounted on a moving part, such as a A C robot hand. The flexing resistance of Robotics Cable at approximately θ θ 400 thousand times is far superior to that of standard cable at approximately 14 thousand times. R **Cable Bending Rupture Test (Tough Cable Breaking Test)** The cable is repeatedly bent with power supplied to check the number Weight of bends until the current is turned OFF.
