7 e3jk e3jk operation adjustment precautions design power reset time the sensor is ready to detect an object within 200 ms after it is turned on. if sensor and load are connected to separate power supplies, ensure to turn on the sensor first. wiring considerations connection/wiring if the dc transistor output type is used, the sum of load cur- rents of l-on output (no) and d-on output (nc) should be within 100 ma. if the sum of load currents exceeds 100 ma, the load short-circuit protection may be activated. (the load short-circuit protection is reset by turning off the power of the photoelectric sensor.) miscellaneous ambient conditions (installation area) the e3jk will malfunction if in stalled in the following places. ? places where the e3jk is ex posed to a dusty environment. ? places where corrosive gases are produced. ? places where the e3jk is directly exposed to water, oil, or chemicals. item through-beam retroreflective models diffuse-reflective model e3jk swing the receiver and emitter ver- tically and/or horizontally and set the adjuster in the center of the range where the indicator of the re- ceiver turns on. like the through-beam model, ad- just the reflector and emitter/re- ceiver. since the directional angle of the emitter/receiver is 1 to 5, ad- just the emitter/receiver especially carefully. (1) if you have a sensing object as shown in the figure, turn the sensitivity adjuster clockwise (increase the sensitivity) until the indicator is turned on, and define this adjuster position as (a). (2) remove the sensing object, turn the sensitivity adjuster clockwise until the indicator is turned on by a background object, and define this posi- tion as (b). (3) turn the sensitivity adjuster counterclockwise (decrease the sensitivity) from (b) until the indicator is turned off, and define this position as (c). (4) the position in the middle of (a) and (c) is the optimum position. if the indicator is not turned on by the background object at the maximum sensitivity, set the adjuster in the middle of (a) and maximum sensitivity. the sensitivity adjuster may be damaged if an excessive force is applied. correct use with sensing object without sensing object operation sensitivity min max reset operation (c) (c) (a) (a) setting (b) background object sensitivity min max (a) sensitivity min max e3jk emitter receiver emitter receiver
