PCB terminals 0V: common DC ground 24V: DC power supply A, B, C, D, E: 24V position inputs DN: down input UP: up input OWT: cabin overload input

Floor table selection Switches SW1 and SW2 are used to select the starting floor offset:

SW1 SW2 offset off off -2 on off -1 off on 0 on on +1

Selected offset is added to position value from inputs A..E.
