For a E3JM with the timer function, the indicator will be lit when incident light is received while the mode is switched to Light-ON, and the indicator will be lit when light is interrupted while the mode is switched to Dark-ON. Move the Emitter and Receiver horizontally and vertically, and locate them to the center of the range in which the Receiver indi- cator is lit. Retro-reflective Models The indicator of the Retro-reflective Model with the timer function is lit in the same way as for the Through-beam Model. As with the Through-beam Model, adjust the Reflector and Sen- sor. Since the directional angle of the E3JM Retro-reflective Model is 1 to 5 degrees, pay careful attention when adjusting the Sensor. Diffuse-reflective Models The indicator of the Diffuse-reflective Model with the timer func- tion is lit in the same way as for the Through-beam Model. 1. If a sensing object is present as shown above, turn the sensi- tivity adjuster clockwise to increase the sensitivity. Point (A) is where the indicator is lit. 2. Remove the sensing object and turn the adjuster clockwise. Point (B) is where the indicator is lit by background objects. 3. Turn the adjuster counterclockwise to decrease the sensitivity, starting from the point (B). Point (C) is where the indicator is lit. 4. The center point between the point (A) and point (C) is the optimum position. If the indicator is not lit by the background object at the maximum sensitivity, set to the center point between the point (A) and the maximum sensitivity. Note: The sensitivity adjuster may be damaged if an excessive force is applied. Precautions for Correct Use Switch Configuration !

Recommended outer diameter of cables is from 6 to 8 dia. Be sure to firmly tighten the cover in order to maintain waterproof and dustproof properties. Cable End Treatment Adjust the four wires to the same length when the Ta output is to be used only. If both the Ta and Tb outputs are to be used, treat them as shown in the following diagram. Recommended Crimp Terminal Dimensions (Unit: mm) Note: Use terminals with insulation tube (recommended crimp terminal: 1.25 to 3.5). Terminal Protection Cover (Accessory) The terminal protection cover is designed to improve safety by maintaining the sensitivity properties of the product and by pre- venting any contact with charged sections while it is being oper- ated with the mode set to the timer mode. Mount the product as shown in the following diagram (mount the Through-beam Model on the Receiver side). Output Relay Contact If a load, such as contactor or valve is used that may produce arc when it is turned OFF, the NC (or NO) side may turn ON before the NO (or NC) side is turned OFF. When using both the NC and NO outputs, use an arc killer. Connecting and Wiring DC SSR Output Models When using the DC SSR output model, the total of the load cur- rent for the Light-ON output (NO) and that for the Dark-ON (NC) should be 100 mA max. If the total exceeds 100 mA, the load short-circuit protection function will be activated (this function will be reset when the power of the Photoelectric Sensor is turned OFF ). MODE 0 1 D·ON L·ON SW1 SW2 TIMER Both SW1 and SW2 at "0." MODE 0 1 D·ON L·ON SW1 SW2 TIMER Only SW2 at "1." MODE 0 1 D·ON L·ON SW1 SW2 TIMER Only SW1 at "1," which overrides either setting of SW2.

Ambient Conditions (Installation Area) The E3JM will malfunction if installed in the following places.
- Places where the E3JM is exposed to a dusty environment. Places where corrosive gases are produced. Places where the E3JM is directly exposed to water, oil, or chemicals. Dimensions Note 1. The operating mode switch and timer mode switch are located inside the cover. 2. All units are in millimeters unless otherwise indicated.
