5.4.2 ElectrIcal Connection to the Loading Island
5.4.2.1 Vehicles and loading islands equipped for therniistor overfill control systems must use a green color coded receptacle socket) on the vehicle, and a green color coded plug on the loading island both fiaturing eight electrical contacts and four attachment j.slosllocking pins, respectively. Both the plug and the receptacle must be designed to be compatible with the receptacle and plug shown in Figure 6A and fiB, respectively.
5.4.2.2 Vehicles and loading islands equipped for optical overfill control systems must use a blue color coded receptacle (socket) on the vehicle and a blue color coded plug on the loading island both featuring six electrical contacts and three attachment j-slots/locking pins, respectively. Both the plug and the receptacle must be designed to be compatible with the receptacle and plug as shown in Figure 7A and 7B. respectively.
5.42.3 Loading islands equipped with a secondary overfill control system that will accept both thermistor type vehicle systems and optic type vehicle systems and will automatically configure itself for proper opcrdtion of either type system (automatic-switching) shall be equipped with a black color coded plug on the loading island, featuring eight electrical contacts and four attachment locking pins.
optionally, if it is necessary for the loading island to accommodate both thermistor and optic type vehicle systems with blue color coded receptacles (sockets) with three attach- merit j-slots/locking pins, a second, blue, three locking pin plug (with six-electrical contact) per 5.4.4.2 may he added to the loading island.
5.4.3 Wiring Standards
5.4.3.1 Thermistor System
The wiring of a thermistor system must be in accordance with Figure 8. The wiring must be color coded in accordance with Table 2. ‘The electrical receptacle (socket) must be color coded green.
5.4.3.2 Optical System
The wiring of an optical system must be in accordance with Figure 9. The wiring must be color coded in accordance with Table 3. The electrical receptacle (socket) must be color coded blue.
5.4.3.3 Data communications may conduct through auxiliary pin 9 or optional pin II as shown in Figure 8 and Figure 9. If optional pin II is used, data shall be in a serial format compatible with known industry standards or a publicly documented format.
5.4.4 Receptacle Construction Standards
5.4.4.1 Thermistor System
Construction details for thermistor receptacles and plugs arc shown in Figure 6A and 6W respectively.
5.4.4.2 Optical System
Construction dctails for optical receptacles and plugs are shown in Figure 7A and 7W respectively.
Optionally. optic type vehicle systems. or vehicles equipped with onboard (the vehiclet control systems with optic type outputs may be equipped with a six electrical contact. blue color-coded receptacle (socket) ftawring four attachment j-slots. This optional configuration (four attachmerit j-sloLs) optic socket is intended for use at loading islands with a “universaL/auto-switching” secondary control system equipped with a black plug as described in 5.4.2.3.
5.4.5 Location of Receptacle
The plug receptacle on the vehicle must be located no more than 7 ft (2.13 m) to the front or rear of the centerline of the bottom-loading adapters and must not interfere with loading operations.
5.5 RECOMMENDED FEATURES
5.5.1 Maintenance
Under normal operating conditions, the SSC system is called upon infrequently. The SSC system should be tested at each regular inspection to ensure that it functions properly.
5.5.2 Labeling
Since diflerent ypes of electrical interface connectors may he used on the same truck or loading island, clear and concise instructions should be readily available and should be obvious to any loader.
• Green color coded (thermistor) loading-island plugs connect to green labeled (thermistor) vehicle receptacles (sockets).
• Blue color coded (optic) loading-island plugs connect to blue labeled toptic) vehicle receptacles (sockets).
