Do not impose 24 VAC on any E2EL model, otherwise it may explode or burn. Load short--circuit Do not short--circuit the load, or the E2EL may explode or burn. The E2EL’s short--circuit protection function is valid, if the polarity of the supply voltage imposed is incorrect and within the rated voltage range. Wiring Be sure to wire the E2EL and load correctly, otherwise it may explode or burn. J CORRECT USE Installation Core Tractive Force Power Reset Time Do not pull cords with the tractive force exceeding the following: The Proximity Sensor is ready to operate within 100 ms after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. pull force (N) = 20 x cable diameter ( mm) Power OFF The Proximity Sensor may output a pulse signal when it is turned off. Therefore, it is recommended to turn off the load before turning off the Proximity Sensor. Power Supply Transformer When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto--transformer. Sensing Object Metal Coating: The sensing distance of the Proximity Sensor vary with the metal coating on sensing objects. Wiring High- tension Lines Mounting The Proximity Sensor must not be subjected to excessive shock with a ha mmer when it is installed, otherwise the Proximity Sensor may be damaged or lose the water--resistivity. Environment Water- Resistivity Do not use the Proximity Sensor underwater, outdoors or in the rain. Operating Environment Be sure to use the Proximity Sensor within operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistive, a cover to protect the Proximity Sensor from water or soluble machining oil is reco mmended so that its reliability and life expectancy can be maintained. Do not use the Proximity Sensor in an environment with chemical gas (e. G., strong alkaline or acid gases including nitric, chromic, and concentrated sulfuric acid gases). Wiring through Metal Conduit If there a power or high--tension line near the cord of the Proximity Sensor, wire the cord through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. 11 E2EL E2EL Item Examples Item AND The Sensors connected together must satisfy the following conditions: (serial connection) iL + (N--1) x i = Upper--limit of control output of each Sensor VS -- N x VR = Load operating voltage N= VR = VS = i= iL = No. of Sensors Residual voltage of each Sensor Supply voltage Current consumption of the Sensor Load current If the MY Relay, which operate at 24 VDC, is used as a load for example, a maximum of two Proximity Sensors can be connected to the load. The number of Sensors connected in parallel varies with the Proximity Sensor model. OR (parallel connection) Effects of Surrounding Metal Shielded types Shielded types allow direct installation on metal plates in an embedded manner without performance change. A minimum distance of 3sn is required between the active surface and a metallic surface in front of the device. (Fig. 1). For SUS shielded types the following minimum distances are required to avoid performance change (see Fig.2 and table below): Shielded SUS Types Free zone E2EL--C2j--DS 0.5 mm E2EL--X2j--DS 0.5 mm E2EL--X4j--DjS 1.0 mm E2EL--X8j--DjS 2.0 mm 3sn Fig.1: Shielded type (except SUS) Freezone 3sn Fig.2: Shielded SUS type Non-shielded types Installation of non--shielded types in metal require the minimum distances according to Fig. 3. 3sn d 2sn 3d Fig.3: Non- shielded type 12 E2EL E2EL 13 E2EL 14 E2EL E2EL E2EL 15 E2EL E2EL NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
