With switch 5 set to normally closed and a wire bridge in 'close photo' input then gates work OK but the close sensor is obviously not functioning. sounds like a main board failure to me but expert opinion would be appreciated.
This sounds like a Photocell problem if the lite goes out with the contacts bridged out.
Double check your connections to the photocell and make sure they are lined up then switch save switch off to see if the lite goes out if it does then switch save back to on.
The circuit needs to learn the saftey circuit by switching the save switch off for 20 second then back on
If this does not cure the problem then you would need new photocells
