Parameter	Operation description
	● SIGNAL ON DELAY ● uses 1 set time (set time displayed on SV display) ● when START signal is applied, timing starts (START signal holds ON status ) ● when displayed time reaches set time output turns ON, holds output and displayed time (ONE-SHOT output selectable)  ● When START signal is cancelled, initializes output and displayed time
	● SIGNAL ON FLICKER - OFF START ● uses 2 set times, Ton and Toff (Toff set time displayed on PV display, Ton set time displayed on SV display) ● when START signal is applied,OFF timing starts (START signal holds ON status) ● when displayed time reaches Toff set time, output turns ON, after displayed time initialization ON timing starts ● when displayed time reaches Ton set time output turns OFF, after displayed time initialization OFF timing starts ● output repeats ON/OFF operations according to Ton and Toff set times ● when START signal is cancelled, initializes output and displayed time

Khi sử dụng chế độ hoạt động POND / PINT / SOND / SINT / SOFD / S.OND / S.INT / S.ODR giá trị thời gian được hiển thị trên màn hình PV và giá trị cài đặt được hiển thị trên màn hình SV.
•    When using POND / PINT / SOND / SINT / SOFD / S.OND / S.INT / S.ODR operation modes, the time value is displayed on PV display, and the set value is displayed on SV display.
•    The operating time timing is performed also during set value change.
•    If there is no key input for more than 1 minute, it returns to operation mode without saving the set value
•    If you press  in operation mode, it enters to set value change mode, and the first digit of SV display flashes
•    Use to move to the position of the digit that you want to change, and use  to change the set value.
•    After changing the set value, press  to save the changed set value and return to operation mode
•    If set value is ‘0’, even if you press  , it does not return to operation mode (you can set ‘0’ in POND / SOND / S.OND / S.ODR operation modes)
Change set value in PFKF / PFKN / TWON / TWOF / S-D / SFKF / SNFN / SNFF / S.FKN operation modes

•    When using PFKF/TWOF/SFKF/SNFF operation modes, OFF time set value is displayed on PV display, and ON time set value is displayed on SV display.
•    When using PFKN / TWON / S-D / SNFN / S.FKN operation modes, ON time set value is displayed on PV display, OFF time set value is displayed on SV display.
•    The operating time timing is performed also during ON time set value and OFF time set value change.
•    If there is no key input for more than 1 minute, it returns to operation mode without saving the set value.
•    If you press  in operation mode, it enters to set value change mode, and the first digit of PV display flashes
•    Use to move to the position of the digit that you want to change, and use  to change the set value
•    After changing the set value of PV display, you can change set value of SV display by pressing  .
•    After changing the set value of SV display, press  to save the changed set value and return to operation mode.
•    If ON time set value and OFF time set value are ‘0’, even if you press  it does not return to operation mode.

Function setting mode

•    Press and hold  for at least 3 sec. in operation mode, to enter function setting mode.
•    Press and hold  for at least 3 sec. in function setting mode to save the changed function mode, and return to operation mode
•    You can switch the function mode with .
•    The OUTT (output time) function is displayed only when the operation modes are POND, SOND, S.OND, S.ODR.
•    The P.RNG (PV time range) function is displayed only when the operation modes are PFKF, PFKN, TWON, TWOF, S-D, SFKF, SNFN, SNFF, S.FKN.
•    The CONT (contact configuration) function is only displayed on LT4 models.
•    The IN-T (input minimum time) function is only displayed on the LT4S models.

Setting item	LCD display	Settings	Initial value
Operation mode selection
Output time setting		● sets ONE-SHOT output operation time ● only in POND operation mode of LT4 models ● only in SOND / S.OND / S.ODR operation modes of LT4S models ● ONE-SHOT output time setting range: HOLD ~ 99.99 sec (HOLD: output hold)
Numeral system selection		● selects the numeral system of time range ● consists of decimal and sexagesimal systems
Addition/ subtraction selection		● selects the timing method of operating time ● consists of "addition timing (UP)", that displays after adding from 0, and "subtraction timing (DOWN)", that displays after subtracting from set value
PV time range selection		● selects PV operating time and PV set value time ranges (refer to the time range for each parameter) ● for PV time range selection, 2 time set values are used in operation mode (ON set value and OFF set value) ● displayed only when the operation modes of LT4 models are PFKF / PFKN / TWON / TWOF / S-D. ● displayed only when the operation modes of LT4S models are SFKF / SNFN / SNFF / S.FKN.
SV time range selection		● selects SV operating time and and SV set value time range (see time range of each parameter)
Minimum input time selection		● displayed only on LT4S models ● selects START / INHIBIT / RESET minimum input time of input signal ● minimum input time consists of 1ms and 20ms
Lock		● used for key lock ● unlocks all keys when you select Parameter “L.OFF” ● when you select Parameter “L.ON” , locks ,   (expcept  ). ● when you select Parameter “L.SET”, locksonly. ● when you select Parameter “L.RST”, locks only.

2.6. Hanyoung LT4S Timer Setting Modes

•    After 5 seconds, the output (must continuously provide input signal) will delay turning on after a set time period for the output to operate.
•    OUT 5 seconds, off 5 seconds, flashing on and off alternately when input signal is applied (input signal must be continuously applied).
•    Out 5 seconds then off (must continuously supply input signal) output operates on set time interval.
•    There is an input signal, Out for 5 seconds then off, the input signal is off, Out for 5 seconds then off (must continuously supply input signal), the output operates for the set time then off until the input is no longer there, then the output returns to operating for the set time then off.
•    After 5 seconds, it is out. If the input signal is cut off, the out will still work for another 5 seconds before turning off. (delay on and delay off).
•    Out will operate when there is a start input signal, and will always operate as long as the input signal is still there. When the start input signal is turned off, that is, when the button is released, Out will still operate until the set time of 5 seconds is over, then it will turn off.
•    After 5 seconds it goes out. Pressing the start button again still doesn't reset the time.
•    OUT 5 seconds, off 5 seconds flashing on and off output alternately.
•    Out 5 seconds then turn off, press start button again to reset time. The output operates on the set time, that is, the set number of seconds, the output operates for that number of seconds.
•    After 5 seconds, it's out. (still delay mode but this time you can press the start button again to reset the time.
