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.
During setup, the H614 automatically determines the normal amperage and
frequency profile and stores it in nonvolatile memory. Then the microprocessor
monitors for amperage changes greater than ±20% of this learned curve.

NOTE: The H614 is not intended
for use in staged pump or variable
inlet vane applications.
NOTE: (Optional) For added
sensitivity in detecting amperage
changes, use H614 devices on all
three phases of the VFD (see “How
It Works” for details).
