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 deenergizes.

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.
