e3t e3t precautions caution avoid damage to the e3t: never apply ac power to the e3t. j avoid damage to the e3t ? do not exceed the rated voltage on the e3t. ? do not short-circuit the load connected to the e3t. ? when supplying power to the e3t, make sure that the polarity of the power is correct. j operating environment to avoid malfunction, do not install the e3t in the following environments: ? locations where the e3t is exposed to intense sunlight. ? locations with high humidity and where condensation may result. ? locations with corrosive gas. ? locations with vibration or shock affecting the e3t. j high-tension lines to avoid sensor damage or malfunctioning due to induction noise, do not place the power supply lines of the photoelectric sensor within the same conduit as power lines or high-tension lines. j cable the cable can be extended up to 100 m provided that cable thickness does not exceed the 0 .3 mm 2 maximum. j power supplies if a switching regulator is connected to the e3t, you must ground the fg (frame ground) and g (ground) terminals, or the switching noise of the switching regulator may cause the e3t to malfunction. j water resistance ? do not use the e3t underwater, outdoors, or in the rain. ? use m2 screws and washers to mount the e3t. when mounting the e3t, never strike the e3t with a hammer, or the e3t will lose its watertight properties. j load short-circuit protection the e3t incorporates a load short-circuit p rotection function. if the load short-circuits, the output of the e3t will be turned off. recheck the wiring and turn on the e3t again to reset the load short-circuit p rotection function. the load short-circuit p rotection function will work if there is a current flow that is 2.4 times larger than the rated load current. when using an inductance load, be sure that the inrush current will not exceed 2.4 times larger than the rated current. j cleaning do not apply paint thinner when cleaning the e3t. paint thinner will damage the casing of the e3t. j indicators the following graphs indicate the status o f each operation level. stable operation range unstable operation range stable operation range operation level x 1.2 operation level operation level x 0.8 stability indicator (green) operation indicator (orange) on off on on off off on note: when the e3t?s operation level is set to the stable operation range, the e3t will be in its most reliable operation without being influenced by temperature, voltage fluctuation, dust, or mounting changes. light be sure to use the e3t within the stable operating range. e3t- jjj 1 e3t- jjj 3 e3t- jjj 2 e3t- jjj 4 j turning on power supply ? the e3t will be ready for sensing 100 ms after the power is turned on. ? if the e3t is connected to a power source different from one for loads, be sure to turn on the power supply to the e3t first. cat. no. e262-e3-3 1/02 specifications subject to change without notice. printed in u.s.a. omron electronics llc oneeastcommercedrive schaumburg, il 60173 note: dimensions shown are in millimeters. to convert millimeters to inches divide by 25.4. 1-800-55-omron omron canada, inc. 885 milner avenue scarborough, ontario m1b 5v8 416-286-6465 r omron on--line global -- http://www.omron.com usa -- http://www.omron.com/oei canada -- http://www.omron.com/oci !
