BFT P7 Opening Time / Not Completing Stroke

[zootreeves]

I'm setting up a BFT P7 with a Rigel 5 control panel. When I set the working time to 45s the closing stroke completes fully (Hits full travel at both ends). However with a 45s working time the opening stroke stops prematurely with perhaps 10cm more travel possible.

If I set the working time to 60s both opening and closing work as expected. But the closing stroke hits maximum travel with 15s to spare and just pushes against itself.

Does anyone know what could be causing this? Is it acceptable to set the working time to 60s?

Thanks
