ST-35C Multiple Point Optic Sensing Overfill Prevention Controller

Brand: Scully Signal Company
The Scully overfill prevention system interfaces with optic sensors. It is typically used for bottom and top-loading of tank vehicles. It is mounted at the loading rack/gantry and connects to the vehicle via the Scully plug and cable assembly. The attached plug and 9.14 meters (30’) cable connect to the vehicle mounted receptacle, or socket, which is wired to the truck sensor. Please consult Scully for alternate plug and socket styles to prevent mixing AV gas and jet fuels in dedicated refuelers. 

The ST-35 system provides the vehicle with an adequate static ground path to the rack/gantry provided the vehicle’s overfill equipment is wired and maintained to factory specifications. For additional ground/earth verification options, consult Scully for information on the Groundhog Self-Proving Grounding System.
Features
  • Maximum safety with Dynacheck® automatic and continuous self-checking circuitry
  • Will not permit loading under any fault or wet sensor condition
  • Signals for automatic shut off of product flow within a half-second of detecting a potential overfill condition
  • Easy connection to vehicles with rugged, versatile plug and cable units
  • Complete compatibility with Scully IntelliCheck® and Load Anywhere® onboard systems and independent five-wire optic sensors
  • ST-35 models monitor 1 – 8 compartment tank vehicles while the ST-35C models monitor 1 – 12 compartment tank vehicles
  • Approved by FM, CSA and ATEX
