HLVA6I23
Single-Phase Monitor
Description
The HLVA6I23 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.
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.
