The drain pan under each reefer unit is molded plastic and carries no metal at all. The yard must know when standing water lies in the pan, and nothing may reach into the water to find it. Once the flag for standing water has come up, the notes settle what follows: the flag goes to the operator in the crane cab on the cab panel itself, with its own tone and its own steady lamp, and the lamp stays lit until the operator clears it. Which pairing belongs in the commissioning notes?
