When input voltage is availbale, closure of the customer supplied contact (C1) will energize the internal relay and begin the timing cycle. At the end of the timed period, the relay will be de‑energized. Closure of the contact (C1) may be maintained, momentary or repeated. The relay will only remain energized for the time period initiated by the initial closure of the contact. The CSB resets when timed cycle is complete with the contact open or the input voltage is removed.
