*If the H614 experiences a momentary loss of power, the Alarm-to-Normal output delay may exceed 1 sec.
Specification Note: For CE compliance, conductor shall be insulated according to IEC 61010-1:2001.
The product design provides for basic insulation only. Use wire with minimum 75°C rated insulation. Do not use the LED status indicators as evidence of applied voltage.
This sensor detects abnormal operation by looking for sudden changes in current across the entire frequency range. In Learn mode, the sensor calculates a margin 20% above and 20% below the learned frequency curve.
An abnormal condition in the circuit is one that falls outside this margin.
DESCRIPTION
The Hawkeye H614 is a microprocessor based, self-learning, self-calibrating current-
sensitive switching device designed for use with VFD 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
FEATURES
● Microcontroller based learning technology...automatically learns load upon
initial power-up...eliminates labor associated with calibration
● Automatic trip point (1.5 to 150 Amps, 12 to 115 Hz)...reduced errors
● Monitors current for both under- and over-load in one package
● Small size fits easily inside small starter enclosures...saves space
● 100% solid state...no moving parts to fail
● Removable mounting bracket for installation flexibility
● 5-year warranty
