Timer Mode 2 (ON-Delay with Reset)
Mode 2 Timer is an ON-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 current time value is non-retentive and will reset to zero on a
loss of power to the smart relay. The timer reset input is Input I1. In the example below, the timer will stop timing
when it reaches the preset value of 5 seconds. Timer status bit T1 will be ON when the current value is 5.
