Automatically Learns At Initial Power-Up

H614

Maximize Reliability

The Hawkeye H614 is a microprocessor based, self-learning, selfcalibrating current-sensitive switching device designed for use with VFD systems. 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. When calibrated for a given VFD system, the H614 is tolerant of gradual drifts in frequency due to expected conditions, such as an accumulation of debris in a filter, while still detecting a sudden drop due to a potential abnormal system condition (e.g., belt loss or other mechanical failure).

AGENCY APPROVALS

Agency Approvals

1. VFD systems generate f ields that can disrupt electrical devices. Ensure that these fields are minimized and are not affec ting the sensor.

2. The H614 is not intended for use in applications where the current is expected to fluctuate by more than 20% due to acceptable causes other than VFD driven changes.

3. If the H614 experiences a momentary loss of power, the Alarm-to- Normal output delay may exceed 1 sec.

4. The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of Conformity for additional details.

Specification Note: For CE compliance, conductor shall be insulated according to IEC 61010-1

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 look ing 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.

NOTE: The H614 is not intended for use in staged pump, variable inlet vane, and other applications in which the amperage changes under normal operation, independent of frequency. NOTE: (Optional) For added sensitivity in detecting amperage changes, use H614 devices on all three phases of the VFD

HOW IT WORKS

During setup, the H614 automatically determines the normal amperage and frequency prole and stores it in memory. Then the microprocessor monitors for amperage changes greater than ±20% of this learned curve, indicating a potential system failure.

ORDERING INFORMATION

1. If the current is above 1.5 A, but neither LED is illuminated, the H614 is considered to be in on/off status mode.

2. Listed for use on 75°C insulated conduc tors.

USAGE EXAMPLE

The H614 is designed for HVAC fan and blower systems, as well as some single stage 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.
