Ladder logic problem for EB NJI044 model.

Hello


i am having a problem with a Hitachi PLC (model EB NJI044) I am doing a "simple" project with 3 cylinders where they extend one after another (i.e) 1 out 2 out 3 out. and then 1 retracts followed by 3 retracting and then number 2 retracting after a 5 second time delay, where the whole cycle runs again. I can get them all out but the time delay has me stumped and the manual is i have is missing a lot of information from it. So it anyone can help me i would be greatful. I am a mature student from the aero industry who has gone back to learn some new stuff!!! Any information with the ladder logic would be appreciated. Thanks again ,


Clive.
