Timer Mode 3 (OFF-Delay)
Mode 3 Timer is an OFF-Delay with reset that will time up to a fixed preset value and stop timing when the
current time is equal to the preset value. Additionally, the Timer current value will reset to zero when Timer is
disabled. In the example below, the timer reset input is Input I01.Timer status bit T01 will be ON immediately when
its rung is true. The timer will only begin timing up when its rung changes to false. Timer status bit T01 will turn OFF
when the current time value reaches its preset value of 10 seconds.
※
T0E and T0F keep their current value after a loss of power to the smart relay if “M Keep” is active, but the others’
reset to 0.
