WARRANTY Limited Warranty5 years AGENCY APPROVALS Agency Approvals UL508 open device, CE: EN61010-1, CAT III, Pollution Degree 2 TM The Hawkeye H614 is a microprocessor based, self-learning, self- calibrating 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). H614 1. VFD systems generate fields that can disrupt electrical devices. Ensure that these fields are minimized and are not affecting 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 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.

Then the microprocessor monitors for amperage changes greater than ±20% of this learned curve, indicating a potential system failure. DIMENSIONAL DRAWING PRODUCT FUNCTIONS WIRING DIAGRAM ORDERING INFORMATION 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. 800.354.8556 | +1 503.598.4564 | sales@veris.com | intl@veris.com | www.veris.com TM Current Monitoring | H614 HQ0002067.G 0117Next >
