• Enclosure Rating: Type 4X (explosion-proof, suitable for outdoor use).

Dimensions:

• Refer to Intellitrol FM data sheet #67247 for detailed dimensions.

Sensor Inputs:

• Supported Sensors:
  • Up to 8 Scully two-wire optic/thermistor sensors (6 or 8 channels).
  • Up to 15 five-wire optic sensors (maximum).
  • Automatic detection of two-wire vs. five-wire sensors.
  • Three-wire, high-temperature thermistor sensors are not supported.

Ground Verification Inputs:

• Ground Bolt Detection: Requires a Scully ground bolt connected to pin 9 of the overfill prevention system socket, installed according to Scully installation instructions.
• Resistive Ground Detection: Requires vehicles to be wired with pins 9 and 10 connected to separate chassis points.

Deadman Input:

• Provides an intrinsically safe input for an optional deadman switch.

Outputs:

• Main Permissive Output:
  • Form-A (“normally open”) AC relay output with monitored redundant contacts.
  • Closes when all conditions (dry sensors, proper ground connection, etc.) are met.
  • Rated for 250 VAC, 5 amps resistive. This output is used for product flow shutdown.
• Main Form-C, Volt-Free Output Relay:
  • Form-C (“normally open” and “normally closed”) volt-free redundant relay output.
  • The relay contacts reverse state when conditions are met.
  • Rated for 250 VAC, 5 amps resistive.
  • The "normally open" contact can be used for product flow shutdown, and the "normally closed" contact is for non-critical output status reporting.

Response Time:

• Maximum of 450 milliseconds after a wet sensor or fault condition.

Communications Port:

• Type: Half-duplex, RS-485 multi-drop communications port.
• Protocol: Modbus™ RTU (straight binary).
• Baud Rate: 1200, 2400, 4800, 9600, or 19200 baud.
• Data Bits: 8 bits.
• Parity: Even, odd, or no parity.

Shipping Weight:

• 31 lbs. (14.1 kg).

Overfill Prevention:

• Automatic Sensor Detection:

  • Automatically detects whether the vehicle is equipped with two-wire optic/thermistor or five-wire optic sensors.
  • Supports up to 8 two-wire or 15 five-wire sensors for monitoring vehicle compartments.

• Dynacheck Continuous Self-Checking Circuitry:

  • Provides continuous monitoring of the system’s health and performance.
  • Checks the controller, wiring, connections, and sensors 30 times per second to ensure everything is functioning correctly.
  • Dynacheck ensures maximum safety by detecting faults promptly and initiating system shutdown when necessary.

• Immediate Shutdown for Overfill/Fault:

  • Automatic shut-off of product flow occurs in less than half a second when overfill or fault conditions are detected.
  • The system is capable of shutting down the flow by controlling valves or pumps.

• Redundant Output Relays:

  • Provides redundant main output relays for fail-safe operation.
  • The system continuously monitors these relays' contacts to ensure proper operation, adding another layer of reliability.

Dynacheck Safety:

• Continuous Monitoring:

  • Pulsed signals are used to constantly check the integrity of the entire system, including the controller, wiring, connections, and sensors.
  • If a sensor comes in contact with liquid or if a system fault occurs, the pulsed signals cease, and the controller immediately triggers a shutdown of the loading operation.

• Automatic Shutdown:

  • The system sends a signal to automatically shut down the operation if a fault is detected, preventing overfill and ensuring safety.

Complete Diagnostics and Communication:

• LED Indicators:

  • Red and Green LEDs display the main status of the system, indicating whether the system is permissive, non-permissive, or in bypass mode.
  • These indicators help operators easily assess the system's operational status at a glance.

• Wet Sensor Detection and Fault Indication:

  • The system provides individual wet sensor detection for each compartment, helping identify which sensor is in contact with liquid.
  • It also displays sensor and wiring faults, offering immediate visibility of any issues for quick troubleshooting.

• Communication Capabilities:

  • The system can communicate with Scully’s Intelliview™ software (a Microsoft Windows®-based application) or integrate with other terminal automation systems.
  • This allows for detailed diagnostics, real-time monitoring, and system management from a central location.

Vehicle Ground Verification:

• Self-Checking Ground Verification:

  • The system performs self-checking ground verification to ensure that a proper ground connection is in place, which is crucial for static discharge prevention during loading operations.
  • This check is performed with a single connection using the overfill prevention plug and cable, simplifying the setup and installation.

• No Separate Grounding Controller Required:

  • There is no need to purchase or install a separate grounding controller. The overfill prevention system incorporates this function, reducing both cost and complexity.

• Automatic Shutdown for Improper Ground:

  • If the system detects that a proper ground bond is not established, it automatically prevents and shuts down the loading operation to avoid hazardous static discharge, ensuring safety.

• Flexible Grounding Configuration:

  • The system can be configured for two types of ground verification:
    • Scully Ground Bolt: A ground bolt mounted to the vehicle chassis for detecting a proper ground connection.
    • Resistive Ground Detection: This method requires separate wiring for pin 9 and pin 10, providing additional flexibility in how vehicles are grounded for different scenarios.

Vehicle Identification:

• Automatic Vehicle ID Detection:

  • The system can automatically read the unique vehicle identification number (VIN) from a Scully vehicle-mounted I.D. module when the overfill prevention plug is connected to the vehicle.

• Communication of Vehicle ID to Terminal:

  • Once the ID is detected, the system communicates the vehicle's identification number to the terminal’s PC, loading controller, or terminal automation system for immediate verification.

• Prevents Unauthorized Loading:

  • If the vehicle fails to meet the terminal’s authorization requirements, the system automatically prevents loading from occurring. This ensures that only authorized vehicles are allowed to load at the terminal.

• Automatic Verification of Vehicle Information:

  • By comparing the vehicle’s unique identification number to the terminal automation system’s re-programmed database, the system can automatically verify:
    • Vapor-tightness certification
    • Contract and insurance status
    • Number of compartments on the vehicle
    • Other vehicle-specific information.

• Streamlined Documentation and Inspection:

  • This system eliminates the need for manual documentation review and inspection, saving time and reducing the risk of human error. Information is automatically verified, ensuring that only vehicles that meet safety and regulatory standards are loaded.

1. Vehicle Ground Verification:
   • Self-checking ground verification with a single connection.
   • No separate grounding controller needed.
   • Automatic shutdown if proper bonding for static discharge is not detected.

   • Prevents loading if the vehicle is not authorized or fails to meet terminal requirements.
   • Automatically verifies vehicle information (e.g., vapor-tightness, contract, insurance).
   • Reduces the time and cost associated with manual documentation and inspection.
