LCD Timer(Touch Type)

Proper usage

Caution

It may give an electric shock if touch the input signal terminal(Between START, RESET, INHIBIT and terminal

) when the power is supplied.

②

Power connection

● Connect AC power line between ( AC power type. Be careful of power connection for DC power type. (

②← ⊖, 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. Therefore please use seperate conduit for power line)

Power start

● Caution for power rising time(100ms) after power on and power falling time(100ms) after power off.

Power

OFF

100

The unstable time

against the input signal

● Power ON Start LE4SA model is starting after 100ms of supplying the power due to rising time of other devices (sensor, etc.) (refer to the above gure.) For ower ON Start, under 100ms setting may cause unstable operation. (it operates normally over 100ms setting) For using under 100ms 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

● Power terminal and Input terminal have not been insulated because there is no power transformer in this Timer.

When using the sensor of SSR output type with input

①

terminal of timer, please check whether Double insulated or not.

Please use double insulated relay when connecting

②

relay output with input terminal.

● Please use 8 Pin socket when connecting this Timer with other equipment and do not touch the socket when power on.

● Please use Power supply with over current protection circuit.(250V 1A fuse)

● When using relay contact as input signal, please use a contact that can function reliable at 5VDC, 1mA.

● In case of connecting START terminal (③) and power terminal (②) 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.

) for LE4S, LE4SA

②-⑦

When connecting more than 2 timers with 1 relay contact

for input or transistor, please wire following <Fig. 2 >. Please use relay contact or transistor to start. (Time error can occurs under 100ms setting because of rising time of Timer).

Change of output operation mode and

timer range

If changing output operation mode or time range,previous reset value will be deleted. But, UP/DOWN selection mode and lock mode 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 2kV, pulse width 1㎲ against Impulse voltage between power terminals and 1kV, pulse width 1㎲ at noise simulator against external noise voltage. Please install MP condensor (0.1 to 1㎌) 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 ammable gas and water, oil, dust exist.

● Where magnetic and electrical noise occurs.

● Where there are high temperature and humidity beyond rated specication.

● Where there are strong alkalis and acids.

● Where there are direct rays of sun.
