LCD imer(ouch ype) Proper usage Caution It may give an electric shock if touch the input signal terminal(between, RESE, INHIBI and terminal ) when the power is supplied. connection Connect AC power line between (-7) for LE4S, LE4SA AC power type. Be careful of power connection for DC power type. (, 7 ) LE4S, LE4SA work stably within range of rated power. (If using power line with another high voltage line or energy line in the same conduit, it may cause inductive voltage. herefore please use seperate conduit for power line) start Caution for power rising time(ms) after power on and power falling time(ms) after power off. ON OFF ms he unstable time against the input signal ms ON Start LE4SA l is starting after ms of supplying the power due to rising time of other devices (, etc.) (refer to the above figure.) For ower ON Start, under ms setting may cause unstable operation. (it operates normally over ms setting) For using under ms time operation, use LE4S, Signal ON Start type. Supply the power at once by a switch or relay contact, otherwise it may cause timing error. Input/Output terminal and Input terminal have not been insulated because there is no power transformer in this imer. When using the of SSR output type with input terminal of timer, please check whether Double insulated or not. Please use double insulated relay when connecting relay output with input terminal. Please use 8 Pin socket when connecting this imer with other equipment and do not touch the socket when power on. Please use supply with over current protection circuit.(5v A fuse) When using relay contact as input signal, please use a contact that can function reliable at 5VDC, ma. In case of connecting terminal (3) and power terminal () of LE4S, do not use it to start at the same time applying power. LE4S is transformer less type, therefore please check following for connecting relay contact for input signal and transistor. When connecting more than timers with relay contact for input or transistor, please wire following <Fig. >. Please use relay contact or transistor to start.

Interval It is able to make Instantaneous ON and time limit OFF (Holding device) with using interval. : imer ime limit Instantaneous ime limit Load LE4S Load <Previous> <Interval > Change of output operation and timer range If changing output operation or time range,previous reset value will be deleted. But, / selection and lock are exception. Change of preset value If changing setting value while time progressing, new preset value should be higher than previous preset value. Otherwise output may work while changing setting value. If changing setting value while it is running, it will work as changed setting value. Please use lock function in order to avoid malfunction. Noise We test kv, pulse width μs against Impulse voltage between power terminals and kv, pulse width μs at noise simulator against external noise voltage. Please install MP condensor (. to μf ) or oil condensor between power teminals when over impulse noise voltage occurs. Environment Please avoid the following places; Where this product may be damaged by strong impact or vibration. Where there are corrosive gas or flammable gas and water, oil, dust exist. Where magnetic and electrical noise occurs. Where there are high temperature and humidity beyond rated specification. Where there are strong alkalis and acids. Where there are direct rays of sun. K-36
