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. 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 scale, returns to zero, and then reaches the new set time. If the set time is changed to a time above the elapsed time, the time delay will continue until the elapsed time reaches the new set 1 time. 2) If the time delay is set to the subtraction direction, time delay will continue until "0" regardless of the new set time. 2. If the set time is changed to "0," the unit will operate differently depending on the operation mode. 1) If the operation mode is set to A (power on delay) or A2 (power on delay), the output will turn on when the power supply is turned on. However, the output I UP keys Changes the corresponding digit of the set time in the addition direction (upwards) O DOWN keys Changes the corresponding digit of the set time in the subtraction direction (downwards) P RESET switch Resets the elapsed time and the output { LOCK switch Locks the operation of all keys on the unit will be off while reset is being input. 2) In the other modes, the output turns on when the signal is input. When the operation mode is C (signal off delay), D (one shot), or F (flicker), only when the signal input is on does the output turn on. Also, when the reset is being input, the output is off. 19 T: Set time t1, t2, t3, ta<T Operation mode Operation type Power on delay (1) A Power on delay (2) A2 Signal on delay B Signal off delay C 20 Explanation * Set the operation mode 1 2 3 section of the DIP switches ON ON ON (no.'s 1, 2, and 3) on the side of the timer as shown. * Clears elapsed time value and starts time delay at power ON. * After time-out, stops at the display of the set value (addition), or stops at "0" (subtraction). * Ignores signal input. * Stops delay time operation at stop ON.
