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. 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 { Set/lock switch Changes over the display between T1/T2 settings, sets the operational mode, checks the operational mode and locks the operation of each key (such as up, down or reset key). Ex: Setting mode display 2. The operational 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. Pulse input OFF-start One operation Pulse input Pulse input OFF-start ON-start Repeating operation Repeating operation Integrating input OFF-start One operation Integrating input Integrating input OFF-start ON-start Repeating operation Repeating operation 3. The operational mode displayed at present is set by pressing the RESET key, and the display returns to the normal condition. 2) Checking the operational 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.) 3) 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 T1 and T2, respectively. 4) Changing over the T1/T2 setting display 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 T1 are linked with those at T2.) * 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. 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 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. When the set times at T1 and T2 are set to 0, the output becomes ON only while the signal input is carried out. However, while the reset input is carried out, the output becomes OFF. 26 PULSE : Pulse input INTEGRATION : Integrating input PULSE A OFF-start/1 operation t1<T1, t2<T2 INTEGRATION A OFF-start/1 operation t1<T1, t2<T2 ta+tb=T1 Power supply tc+td=T2 Output Delayed one shot T2 ta tb tc td t1 T1 t2 Stop Reset Reset Signal Signal PULSE B OFF-start/repeating operation t1<T1, t2<T2 ta+tb=T1 Power supply tc+td=T2 T1 T2 T1 T2 ta tb tc td t1 td te tf tg th t1 ta+tb=T1 Power supply ta Stop Reset Reset Signal Signal ta+tb=T1 Power supply tc+td=T2 Output T1 t2 tc+td=T2 te+tf=T1 tg+th=T2 tb tc td te tf tg th T1 T2 t1 T1 t2 * When the power is turned on, the timer value is not cleared.
