The Hawkeye H614 is a microprocessor based, self-learning, self-calibrating current-sensitive switching device designed for use with VFD (Variable Frequency Drive) systems. It is equipped with an auto calibration feature that allows the device to distinguish between a reduced amp draw due to normal changes in frequency (e.g., gradual filter restrictions) and a sudden drop (e.g., belt loss or other mechanical failure). At initial power-up, the H614 automatically learns the average current on the line with no action required by the installer. Once a current is learned, the switch monitors for changes in current greater than ±20% of the learned load.

APPLICATIONS

• Detecting belt loss, coupling shear, and mechanical failure
• HVAC fan/blower motor failure
• Detecting unauthorized duct access

Automatic calibration...reduced errors and installation costs

• Microcontroller based learning technology...automatically learns load upon initial power-up...eliminates labor associated with calibration
• Monitors current and frequency for both under- and over-load in one package
• Small size fits easily inside small starter enclosures...saves space
