Garage door IR beam not resetting

[DLA123 0]

Hi all, 

Setup - FGR-223 controlling up/DN on a roller door with an IR beam sensor wired to S2 so i don't crush cars. 

 

Issue -  All works fine but when i trip the IR beam (to simulate a car in the way) the drive signal stops (good) then when i reinstate the beam it is like the FGR-223 will not reset. the only way i can get it to work again it to change parameter 151, save and change it back to 151=4 save and all good until beam trip again. 

 

Failed attempted solutions - 

1. Changed parameter 151 to 3 and 4 not change.

2. Set parameter 41 to 4 then made a scene on the hold of the button but there is no option to make a scene on the release of a button to restart or reset.  

3. Randomly checked and unchecked boxes (surprisingly this did not resolve the issue). 

 

Is there any manual for this device that goes more in depth than the basic one found on the website support? 

 

Any advice would be appreciated. 

 

Thanks in advance.
