When input voltage is available, closure of the customer supplied contact (C1) or application of the control voltage will energize the internal relay. When the contact is opened or control voltage removed , the timing cycle begins. At the end of the timed period, the relay will be de‑energized. Reclosure of the contact or control voltage during the timing cycle will reset the timer. The CFB resets when the control contact (C1) is reclosed or the control voltage is reapplied.
