A smart module circuit board carries a programmable microprocessor and a plurality of relay type interface circuits for use in organizing relatively high voltage input devices and output devices into a complex system wherein a programmed combination of input device signals determines when and if to energize one or more output devices in the system. The interface circuit comprises input and output stages which operate on logic level voltages and which are decoupled by opto-couplers from a relatively high voltage energization circuit which passes through a relatively high voltage electrical device. The energization circuit comprises a triac which is operated by the output stage in response to outputs from the microprocessor, a manual switch connected in parallel with the triac so that a given electrical load device can be manually activated and a multi-colored LED for indicating the conditions of the input and output circuits individually and in combination. The smart modules are utilized in a vehicle laundry having a master computer for overall control of multiple smart modules, the microprocessor of each smart module being independently operable to control at least a portion of the laundry system in the event of a failure of the master computer.

An above the floor conveyor is provided for transporting a wheeled vehicle having a plurality of tires across a floor surface with a pair of the vehicle's tires oriented in a guided track. The conveyor includes a drive and idle sprocket which are spaced apart and have an endless tensile member extending in a loop thereabout to define a drive and a return flight. A series of dolly assemblies are attached to the endless conveyor tensile member in spaced apart orientation. The dolly assemblies have an elongated dolly roller for engaging a tire of a vehicle located within the guided track. The dollies are pivotable about a generally vertical dolly axis between an inactive position in which the dolly roller is pivoted rearwardly out of the guided tracks and an active position in which a dolly roller extends inwardly into the guided track. The dolly assembly has an arm extending outwardly from the pivot axis providing a follower spaced from the axis. A dolly guide rail is fixed parallel to the drive flight for cooperating with the dolly follower to support the dolly when in the active position. An actuator is provided to selectively shift the dolly between the inactive and active positions on demand.
