Table 1: Setting the operation mode DIP switches DIP switch OFF ON Item 1 2 3 Operation mode *4 Minimum input reset, start, and stop signal width DIP switch No. 1 2 3 ON ON ON OFF OFF OFF ON OFF OFF OFF ON OFF ON ON OFF OFF OFF ON ON OFF ON OFF ON ON Refer to table 1 20 ms 1 ms 5 Time delay direction Addition Subtraction 6 Time range Refer to table 2 7 8 * The 8-pin type does not have the stop input, so that the dip switch can be changed over between reset and start inputs. The signal range of the lock input is fixed (minimum 20 ms). Table 2: Setting the time range DIP switch No. Time range 6 7 8 ON ON ON 0.001 s to 9.999 s OFF OFF OFF 0.01 s to 99.99 s ON OFF OFF 0.1 s to 999.9 s OFF ON OFF 1 s to 9999 s ON ON OFF 0 min 01 s to 99 min 59 s OFF OFF ON 0.1 min to 999.9 min ON OFF ON 0 h 01 min to 99 h 59 min OFF ON ON 0.1 h to 999.9 h Notes: 1) Set the DIP switches before installing the timer. 2) When the DIP SW setting is changed, turn off the power once. 3) The DIP switches are set as ON before shipping.

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. 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 1) or A2 (power on delay 2), the output will turn on when the power supply is turned on. However, the output will be off while reset is being input. 2) In the other modes, the output turns on when the start is input. When the operation mode is C (signal off delay), D (Pulse one shot), or F (Signal flicker), only when the start input is on does the output turn on. Also, when the reset is being input, the output is off. • Power failure memory The EEPROM is used for power failure memory. It has a life of Min. 105 over-writings. The EEPROM is overwriting with the following timing. Output mode Power ON delay (2) A2 Addition G Other modes Overwrite timing When power is OFF Change of preset value or start, reset input When power is OFF after being ON When power is OFF after changing preset value * Be aware that the contents of EEPROM for all modes will be overwritten when power is turned OFF during input to external lock terminals R to E and 7 to 6 . Such an action does not exist by doing lock operation from the front.
