VERIS INDUSTRIES
Automatically Learns At
Initial Power-Up
DESCRIPTION
The Hawkeye TruStat H10F is a microprocessor based, self-learning, self-calibrating
current switch. It provides calibration-free status, for both under-current and overcurrent conditions. At initial power-up, the H10F 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
● Verifying lighting circuit and other electrical service run times
● Monitoring status of industrial process equipment
● Monitoring status of critical motors (compressor, fuel, etc.)

HOW IT WORKS
The compact split-core H10F current switch monitors a learned load current to detect
power loss and electrical overload of fans, blowers, pumps, chillers, or any other
critical motor functions. The push-button initiated LEARN MODE allows resetting of
the monitored current when the load changes due to system alterations.
LEARN MODE
● Unit automatically enters LEARN MODE upon initial power-up
● Auto-calibration is achieved by averaging the load current for 30 seconds
● During this stage, green and red LEDs blink on/o
● STATUS OUTPUT contacts are closed
● LEARN MODE may be initiated manually
NORMAL MODE
● Initiated after the 30-second learning period, or immediately upon power-up if
sensor has already learned a load
● The red LED is o, and the green LED is blinking
● STATUS OUTPUT contacts are closed

ALARM MODE
● The ALARM state signals low current, high current, or power loss conditions
● Initiated within 1 second when any load current excursion exceeds a nominal
±20%
● ALARM will persist until the load current returns to within a nominal ±15% of
the learned current value, or when power is restored to normal
● The 5% ALARM-to-NORMAL MODE reentry margin prevents alarm signal
oscillations. This feature is enhanced by a 30 second delay, to insure true
nominal load current conditions when returning to NORMAL MODE from an
ALARM state
● The green LED shuts o, and the red LED blinks
● STATUS OUTPUT contacts are open
