VFD Current Switch
Auto Calibration
Automatically Learns Load
At Initial Power-Up
DESCRIPTION
The Hawkeye H614 is a microprocessor based, self-learning, self-calibrating currentsensitive 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 lter 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
current monitoring
● Detecting unauthorized duct access

H614
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 ts easily inside small starter enclosures...saves space
● 100% solid state...no moving parts to fail
● Removable mounting bracket for installation exibility
● 5-year warranty

*If the H614 experiences a momentary loss of power, the Alarm-to-Normal output delay may exceed 1 sec.
Specication No te: For CE compliance, conductor sha ll be insulated according to IEC 61010-1:2001.
The product d esign provides for basic insul ation only. Use wire with minimum 75°C rated insula tion. Do not use the LED status indicato rs as evidence of applied volta ge.
This sensor detec ts abnormal operation by l ooking for sudden chang es in current across the entire fre quency range. In Learn mode, t he sensor calculates a margin 20% ab ove and 20% below the learned f requency curve.
An abnormal con dition in the circuit is one th at falls outside this margin.

HOW IT WORKS
The H614 is designed for HVAC fan and blower systems, as well as some pumping
systems involving consistent viscosity liquids. If an H614 is installed on one phase
of the VFD, it detects changes in that phase that result from the VFD compensating
for changes elsewhere in the system. Alternatively, for increased sensitivity, H614s
can be used on all three phases for immediate detection of phase balance changes
anywhere in the system.
APPLICATION/WIRING DIAGRAM
NOTE: The H614 is not intended
for use in staged pump or variable
inlet vane applications.
NOTE: (Optional) For added
sensitivity in detecting a mperage
changes, use H614 devices on all
three phases of the VFD (see “How
It Works” for details).
During setup, the H614 automatically determines the normal amperage and
frequency prole and stores it in nonvolatile memory. Then the microprocessor
monitors for amperage changes greater than ±20% of this learned curve.
