PRA Series Diversified Electronics atcdiversified.com 800.727.5646 214 Phase Voltage Monitors// PRA Series The PRA-100 Series Phase Sequence Monitors are designed to allow the output to energize only when the phase connections are in the proper sequence. For use in applications where motor direction is critical or the installation is required by code to have sequence detection. When the phase sequence is correct and the operating voltage is present on all phases, the relay will energize and the green LED indicator will glow. If the phases are in reverse rotation, the relay will not energize and the red LED indicator will glow. The PRA-100 Series will not detect phase loss while the motor is turning.
