8. A new printing station will add a logo to parts as they travel along an assembly line. When a part arrives a part sensor will detect it. After this the `clamp’ output is turned on for 10 seconds to hold the part during the operation.
For the first 2 seconds the part is being held a `spray’ output will be turned on to apply the thermo set ink. For the last 8 seconds a heat output will be turned on to cure the ink. After this the part is released and allowed to continue along the line. Write the ladder logic for this process. [16]
