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.
