Faac 770 455D Gates Auto closing

[SamA]

Hi,
I have Faac 770 230v newly installed with 1 set of sensor on the piers. 
I have recently completed wiring same up and have progressed to the Learning process which is completed. I have installed a switch beside the intercom inside and it wired up. 
In have followed the advanced or complete learning on the gates which has worked fine and exited same with pressing F. 
Status on the 2 digit display to the left now shows 3 lines.

Problem is the Gates won't auto close. 

I'm tearing my hair out here. Any help welcome.

Hi,

Are the three diagnosis lines horizontal or vertical?

Sam.
