When input voltage (A1) – (A2) is applied, the contact 15 – 18 is closed and remains in operation for as long as input voltage is applied.
On expiry of time (T1), the contact 25 – 28 is energized and remains in operation until the input voltage is removed. At the end of time elapsed both relay de-energized. If the input voltage is removed from the unit before time has elapsed,
the time is cancelled and the relay de-energize.
