Dispensing Cutoff System

DC400

Dispensing Cutoff System

The DC400 Dispensing Cutoff System is a stand-alone, solid state two-part system which includes a controller and sensor, designed to automatically shut down product flow if liquid is detected inside containment spaces. Ideal for retrofit applications, the DC400 allows for easy compliance with new and evolving regulations, without the added expenses of shutting down your site to break concrete for new conduit and wiring installation. The DC400 can be mounted inside any turbine sump to provide complete pump shut down or mounted directly into dispenser sumps, allowing only the effected dispenser to be shut down as liquid is detected.

  • Automatically stops fuel from dispensing in the event of liquid detection.
  • Easily installed in either turbine or dispenser sumps.
  • Ideal for retrofit applications as system connects to existing turbine or dispenser wiring, eliminating the need to pull new wires or break concrete.
SENSOR SELECTION

No matter what the monitoring application is, Franklin Fueling Systems offers a sensor solution tailored to the specific requirements of each application.

SENSOR SELECTION GUIDE
Sensor Selection Wide Short.psd
ATG REQUIREMENTS

All sensors require an EVOTM Series fuel management system. Depending on the sensor type, either two-wire or three-wire sensor modules are used to power and control the sensors.

TSP-ULS.psd

Non-Discriminating Sensors

These sensors are able to detect and send an alarm signal if the presence of liquid appears inside of a containment space.

TSP-DDS.psd

Discriminating Sensors

These sensors are able to detect and send an alarm signal if the presence of liquid appears inside of a containment space and can also differentiate between liquid and hydrocarbons (fuel).

Applications

  • Containment sump liquid detection resulting in dispensing cutoff.

Installation

Simply mount the 404-4 controller inside any containment sump and connect it to the existing turbine or dispenser wiring. (Dispenser installations require an electrical junction box with an open conduit hub).Connect the liquid sensor using the supplied watertight splice kit. Suspend it so it is just touching the bottom of the containment sump.Not for use with 3-phase motors or Variable Frequency Drive installations.

General

  • 404-4 Controller is compatible with:
  • S404 Liquid Sensor
  • Note: Previous versions of the 404-4, S406, and S404 are not compatible. Both the controller and sensor must be replaced if either requires it. Core credit available for legacy items.
  • Dimensions:
  • 404-4 Controller: 6.6" x 6.2" x 3.2" (167mm x 157mm x 81mm)
  • S404 Liquid Sensor: 1 1/2" x 3 1/2" (38mm x 89mm), 25' (7.6m) cable length
  • 404-4 Input power: 90-250 VAC, 50/60 Hz, 0.25 A
  • 404-4 Relay contacts: 12A, 2 hp @ 250 VAC, 12A, 1.5 hp @ 120 VAC
  • Operating temperature: -4 to 140 °F (-20 to +60 °C)
  • Enclosures: All sensors intrinsically safe, controller explosion proof
  • Detection time: <1 second
  • S404 sensor minimum detectable water limit: 0.98" (25 mm)

Capabilities

  • Cutoff power to submersible pumps or dispensers when liquid is detected in containment sumps.
  • Automatic reset on liquid removal.
