Trade timer

[Doomed]

I have been asked to reduce the length of the trade button activation time on this door entry syste, but I'm blowed if I can figure it out.
Any help please.

Downloads available from this page and also here. Timing is covered in tech data download from first link, but not certain if it covers exactly what you require.

Thank you!
Never noticed that flap that has the time settings hidden behind it!
