Chapter 4 Relay Ladder Logic Programming 63
Timer Mode 6 (FLASH with Reset)
Mode 6 Timer is a Flash timer with reset that will time up to a fixed preset value then change the state of its
status bit 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. In the example below, the timer reset
input is Input I1. Also in the example below, timer status bit T1 will be ON immediately when its rung is true
and begin its timing sequence. Timer status bit T1 will turn OFF when the current time value reaches its
preset of 5 seconds. This Flash sequence of the timer status bit T1 will continue as long as its rung remains
true.
