After the relay is energized, 15-18 is closed, the motor
rotates forward, and the delay t1 is turned off, stopping
the motor. After a further delay of t2, 25-18 closes,
and the motor reverses. After a delay of t3, 25-28 opens,
and the motor stops. This cycle continues.At any
moment, switch on A1-S, the motor stops running, and
the delay pauses
