After mounting the first pair of corner trip arms at an outer slowdown boundary (Bridge slowdown and
Trolley slowdown) and wiring the limit switches, move the crane into a position that trips both the Bridge
and Trolley 4-pole limit switches.
Examine the UI Outputs screen to verify the displayed limit switch states match the tested direction of
travel using the steps below.
