LPVRB Operation with Options
A unique microcontroller-based voltage and phase sensing circuit
constantly monitors the three phase voltages to detect harmful
power line conditions. When a harmful condition is detected, the
LPVRB’s output relay is deactivated after a specified trip delay.
The output relay reactivates after power line conditions return to
an acceptable level for a specified amount of time (Restart Delay)
or after a manual reset. The trip and restart delays prevent
nuisance tripping due to rapidly fluctuating power line conditions.
The Model LPVRB automatically senses whether it is connected to
to 416 V 50 Hz system. An adjustment is provide to set the normal
line voltage from 190-240 or 380-480 VAC. Other adjustments
include a 1-30 second trip delay, a 1-500 second restart delay, and
a 2-8 % voltage unbalance trip adjustment.
Voltage, Over Voltage, Phasing Fault/Reverse Phase, and Manual
Reset. The LPVRB ships with a jumper installed for automatic
restart. A connector with 12” wires is included for manual reset
switch.formation, item 7.1.
