Setting the operation mode and time range
Setting procedure 1) Setting the time range (Timer T
Setting procedure 2) Setting the operation mode
Set the operation mode with the keys on the front of the LT4H-W timer.

1) Setting or changing the operation mode
(1) When the UP or DOWN key at the first digit is pressed with the SET/LOCK
switch pressed, the mode is changed over to the setting mode.
(2) Now release the SET/LOCK switch.
(3) The operation mode in the setting mode is changed over sequentially in the left or right direction by pressing the UP or DOWN key at the first digit, respectively.
(4) The operational mode displayed at present is set by pressing the RESET switch, and the display returns to the normal condition.
2) Setting (changing) the time
(1) Pressing the SET/LOCK key switches the set value display between T1 and T2. Display the timer (T1 or T2) which is to be set (or changed).
(2) After displaying the timer (T1 or T2) which is to be set, press the UP or DOWN key to change the time.
• Checking the operation mode
When the UP or DOWN key at the second digit is pressed with the SET/LOCK switch pressed, the operational mode can be checked.
The display returns to the normal condition after indicating the operational mode for about two seconds. (While the display indicates the operational mode for about two
seconds, the other indicators continue to operate normally.)
• Setting the lock
When the UP or DOWN key at the fourth digit is pressed with the SET/LOCK switch pressed, all keys on the unit are locked.
The timer does not accept any of UP, DOWN and RESET keys.
To release the lock setting, press the UP or DOWN key at the fourth digit again with the set/lock switch pressed.
* Operational mode, adding and subtracting and minimum input signal range cannot be set at T
• Changing over the T
The T1/T2 setting display is changed over by pressing the SET/LOCK switch. (This operation gives no effect on the other operations. The set time and elapsed time
(residual time) at T
• Changing the set time
1) It is possible to change the set time with the UP and DOWN keys even during time delay with the timer. However, be aware of the following points.
2) When the set times at T
becomes OFF.
Front display section
(1) If the set time is changed to less than the elapsed time with the time delay set to the addition direction, time delay will continue until the elapsed time reaches full
(2) If the time delay is set to the subtraction direction, time delay will continue until “0” regardless of the new set time.
