Problem Sheet 12
Cementing Press
Problem:
A push button is to control the forward stroke. After the piston rod has reached the forward end position, the components are to be pressed together for 10 seconds. Then the piston rod is to return automatically to the initial position.
Additional conditions:
The return stroke must occur even if the start push button is still pressed.
A new start signal may only become effective after the initial position has been reached and after the push button has been released.
