Description
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 30 A,
1 hp 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 120 VAC or 208 to 240 VAC systems.

Dashed lines are internal
connections.
Upon application of input voltage the output relay re-
mains 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 energiz-
es. 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.
