I have a similar lift on my thomas. for me, there is no joy without the engine running and parking brake on and wheelchair door open. i also have a switch called 'lift' which must be on. i assume yours is on because you have the green light on the lift control box. I'm sure there are various interlocks and they are different on each bus. One may require the air system to be full so it can engage the brake.
My bet in your case is run the bus till air pressure warning is off, keep in N with air brake on, open and secure rear door, ensure the seatbelt 'on the lift' is fastened.
keep in mind that any of those 3 interlock buttons on the side of the door frame may impact the process. ie: one may confirm the door is open, one may confirm the door is stowed securely open, and another confirm the door is closed, seems redundant. Shoot, one may be related to pendant placement
