Example 11 | Fluid pumping process | PLC Programming

The process involves pumping fluid from tank A to tank B. The operation of the process can be summarized as follows: Before starting, PS1 must be closed.
When the start button is pushed, the pump starts. The button can then be released and the pump continues to operate.
When the stop button is pushed, the pump stops.
PS2 and PS3 must be closed 5 s after the pump starts. If either PS2 or PS3 opens, the pump will shut off and will not be able to start again for another 14s.

shouldn't ps2&3 be connected in series, as it is given that if either of them opens, the pump should stop?

Hello bro, don't you have it running in RSLogix?

wrong here PS 2 and PS 3 must be in series only then if either of one opens the pump will shut off .
