To accomplish this an off-delay timer (TR) is used. When the start button is pressed, it energizes both Ml and TR. The operation of TR closes its time delay contact but the circuit to M2 is kept open by the opening of the instantaneous contact. As soon as the stop button is pressed, both Ml and TR are dropped out. This closes the instantaneous contact on TR and starts M2. M2 will continue to run until TR times out and the time delay contact opens.
