BIG UP THE BASIC STANNAH LIFT - With motor room

On the way up it's a lively little one - the cab shakes about, but overall it's a really basic 2 landing Hydraulic lift. That was until I filmed it, BIG UP THE BASIC STANNAH LIFT! The controller can do up to 5 landings, Inputs and Outputs for floors 3 to 5 are not in use here. This time I've not labelled up the controller's inputs and outputs and kept the abbreviations. See if you can work out what's what? I'll get you started... OUTPUTS are Green LEDs: CDR = CLOSE DOOR RELAY ...? INPUTS are Red LEDs: DOP = DOOR OPEN PUSH button ...?
