Voltage Monitors
HLV Series
The HLV Series is a single-phase undervoltage
monitor designed to protect sensitive equipment
from brownout or undervoltage conditions. Time
delays are included to prevent nuisance tripping
and short cycling. The 30A, 1hp rated, SPDT relay
contacts allow direct control of motors, solenoids
and valves. The output relay can be ordered with
isolated SPDT contact to allow monitoring of one
voltage and switching a separate voltage. Two
undervoltage trip point ranges allow monitoring
of 110 to 120VAC or 208 to 240VAC systems.
For more information see:
Appendix B, page 165, Figure 2 for dimensional drawing.
Appendix C, page 169, Figure 15 for connection diagram.
Operation
Upon application of input voltage the output relay remains de-energized. When the input voltage value is above
the pull-in voltage, the restart delay begins. At the end of the restart delay, the output relay energizes. When
the input voltage falls below the trip point, the trip delay begins. If the input voltage remains below the pull-in
voltage for the entire trip delay the relay de-energizes. If the input voltage returns to a value above the pull-in
voltage, during the trip delay, the trip delay is reset and the relay remains energized. If the input voltage falls
below the trip point voltage during the restart delay, the delay is reset and the relay remains de-energized. Reset
is automatic upon correction of an undervoltage fault.
Reset: Removing input voltage resets the output relay and the time delays.
