daitem d5131 indoor controller issue

[hirst007]

Hi recently moved in to a.house it has daitem d5131 electric gate.
Now the problem I have is on the indoor station on the display.
the status of the gate is always shown as closed. The gate opens and closes when I press the button and the gate opens and closes when I use my fob.
But the status on the dispatch never changes . Can someone please advise me. On what the problem is and how to resolve it.
Many thanks.
Regards
Andy

The gate status is based on the status of a position contact (see the 19th page of the manual in http://www.gateguide.co.uk/showthread.php?tid=4889 - look at terminal block positions 15 & 16).

This position contact may not be installed or be damaged, the connecting cable may be damaged etc.
