Virgil,
It appears that the motor starts to run as soon as you turn on the switch and continues to run until one of the limits is tripped. The limits pick up the time delay relay coil and the motor relay coil. The motor relay coil is sealed in through the normally closed time delay contact and the normally open motor relay contact. It appears that the time delay relay is of the pneumatic type. The timing will start after the limit switch returns to the open position. After the timer times out its contact will open and this will in turn drop out the motor relay and the motor will again be powered through the normally closed motor relay contact.
