Temperature Range: Operating IC models: -40° to +140°F (-40° to +60°C) Storage -50° to +185°F (-45° to +85°C)
Power Requirements: 100 – 130 VAC (120 VAC setting) or 200 – 250 VAC (240 VAC setting) 50/60 Hz, 30 watts maximum
Enclosure: Explosion-proof, weathertight housing with powder-coated, corrosion-resistant finish. Weathertight rating: Type 4X and IP 65.
Approvals: IC models: FM and FMC approvals for use in Class I, Division 1, Group C and D hazardous locations, Type 4X.
Dimensions: Refer to diagram on Intellitrol FM data sheet #67247
Sensor Inputs: Up to 8 Scully two-wire optic/thermistor sensors (6 or 8 channels) or 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: When configured for ground bolt detection, a Scully ground bolt connected to pin number 9 of the overfill prevention system socket(s) and installed onto the vehicle frame per Scully installation instructions (No. 61081) is needed to satisfy this input. When configured for resistive ground detection, all vehicles must be wired with socket pin number 9 and 10 connected to separate points on the vehicle chassis.
Deadman Input: An intrinsically safe input is provided for an optional deadman switch.
Outputs: Two independent outputs are provided as follows: Main Permissive Output: A Form-A (“normally open”) AC relay output with “monitored redundant contacts.” This output closes when all overfill prevention sensors are dry and functional, a proper ground connection, and/or vehicle identification (optional), and/or deadman (optional) is established. This output is an AC control output and must only be used with AC voltage. This output should be used for product flow shutdown capability and is rated at 250 VAC, 5 amps resistive. Main Form-C, Volt-Free Output Relay: A Form-C (“normally open” and “normally closed”) volt-free redundant relay output contact. These output contacts reverse state (“normally open” closes and “normally closed” opens) when all overfill prevention sensors are dry and functional, and a proper ground connection, and/or deadman (optional), and/or vehicle identification is established. If a volt-free relay output contact is needed, the “normally open” relay output contact may be used for product flow shut down. The “normally closed” relay output contact is intended for any additional non-critical output status reporting functions. This Form-C contact is rated at 250 VAC, 5 amps resistive.
Response Time: 450 milliseconds maximum after wet sensor or fault condition.
Communications Port: The communications port is a half-duplex, RS-485 multi-drop communications port, utilizing Modbus™ RTU (straight binary) communications protocol at 1200, 2400, 4800, 9600 or 19200 baud rate; 8 bits; even, odd or no parity.
Shipping Weight: 31 lbs. (14.1 kg.)
  • Automatic detection of two-wire optic/thermistor or five-wire optic vehicle sensors.
  • Monitors up to 8 two-wire and 15 five-wire vehicle sensors.
  • Maximum safety with Dynacheck automatic and continuous self-checking circuitry.
  • Signals for automatic shut-off of product flow in less than a half-second of overfill/fault detection.
  • Redundant main output relays and continuous monitoring of relay contacts for fail-safe relay operation.
  • Dynacheck uses pulsed signals to continuously check the entire system.
  • The controller, wiring, connections and sensors are checked for faults 30 times per second.
  • If a sensor comes in contact with liquid, or in the event of a system fault, the pulsed signals cease, and the controller automatically signals for immediate shutdown of the loading operation. Shutdown is accomplished by controlling valve or pump controls.
  • Prominent red and green main status LED indicators indicate permissive, non-permissive and bypass conditions.
  • Individual wet sensor detection by compartment and indication of sensor and wiring faults.*
  • Communicates with Scully’s Intelliview™ Microsoft Windows® based software or your terminal automation system.
  • Incorporates self-checking ground verification with a single connection via the overfill prevention plug and cable.
  • No need to purchase a separate grounding controller.
  • Prevents and shuts down loading if a proper bond for static discharge is not detected.
  • May be configured for use with a Scully Ground Bolt mounted to the vehicle chassis or for resistive ground detection.
  • Automatically reads the unique vehicle identification number of the Scully vehicle mounted I.D. module when the plug is connected to the vehicle.
  • Communicates the vehicle identification number to the terminal’s PC, loading controller or terminal automation system.
  • Prevents loading if the vehicle fails to meet the terminal’s authorization requirements.
  • By comparing the unique vehicle identification number to the terminal automation system’s re-programmed database, the terminal may automatically verify information such as: vapor tightness certification, contract and insurance status, the number of compartments and other vehicle information.
  • Eliminates the time and expense of manual documentation review and inspection.
