Programming Function Blocks and Features

Interval Timer

This timer counts down from the preset value in minutes. This time remaining is CVn OV. The timer has a single discrete output CVn OS which is ON(1) while the timer is actively counting or while RESET is ON(1), and OFF(0) while the timer has timed out to zero. When RESET/RUN switches ON(1) the timer resets to the preset value; an ON(1) to OFF(0) transition starts the timer.

Table 4-34 describes the Interval Timer prompts. See Table 4-2 for additional prompts.
