Output Operation Mode
■ LE3S
mark - START signal: continuously ON → time starts and output operates.
mark - START signal: though the one-shot input is occurred time starts and output
operates. (one-shot input signal: ≥ 20 ms)
Initial status: UP mode - Display value 0, output OFF
DOWN mode - Displays the setting time, output OFF
If the setting time is '000', the control output does not switch to ON.
The input time of output operation mode D, E: ≥ 100 ms
• T : setting time
• T = T1 + T2 + T3, T ＞ Ta + Tb
