Scully IntelliCheck®3 Overfill Control Unit

Scully's IntelliCheck®3 is the safest and most advanced tank trailer overfill prevention and retained product monitoring system. It saves time and money by reducing down-time and ensuring safe, dependable loading operations.

Features

• Advanced, easy-to-understand diagnostics with Bi-color LEDs
• High-level detection in each vehicle compartment, using either Scully 2 Wire or 5 Wire sensors
• Simplified programming
• System shutdown within one-half second of high-level or fault condition detection
• Individual sensor indicators for static conditions such as "wet" sensor or operational faults
• New 5 Wire Series Wired Sensor compatibility adds diagnostic capability to 5 wire vehicles
• Detects opens, shorts and helps pinpoint specific sensor to save time in troubleshooting
• Prevents bypassing sensors for maximum safety
• RoHS compliant design to protect the environment
• Corrosion resistant housing
• Impact and UV resistant window for improved performance
• Dual Level model available to detect and control 2 sensors per compartment

• Complete automatic and continuous checking of all system components for static operation
• Complete system diagnostics
• Visual indication of Dynacheck® self-checking, sensor status and fault conditions
• Indicator for auxiliary switch operation, such as vapor interlock
• Loading rack connection indicators

• Retained product detection using two-wire optic sensors
• Loading "lock-out" feature if vehicle returns with product
• Driver must press retained product acknowledge button for loading to occur
• Helps prevent product mixing
• Warns against overfilling of vehicle compartments

• Scully optic sensors are used as the "eyes" of the Intellicheck®3 to determine loading status
• Each sensor is independently monitored and tested up to 30 times per second
• Withstands extreme road and temperature conditions
• IntelliCheck® Kits include Scully sensors- the most reliable sensors in the market with nearly double the warranty of any other sensor
