Description

The 202 Series is a 3-phase, auto-ranging, dual-range voltage
monitor that protects 190-480VAC, 50*/60Hz motors regardless
of size. The 202-RP (and the 202-575-RP for 475-600VAC)
monitors the phase rotation of 3-phase systems and trips on
reverse-phase only. Critical applications include fan motors,
scroll compressors, grinders, conveyor systems, elevators and
escalators. Both products provide a user selectable nominal
voltage setpoint and automatically select between the 200V and
400V range.

This unique microcontroller-based voltage and phase-sensing
device constantly monitors the 3-phase voltages to detect
harmful power line conditions. When a harmful condition is
detected, the MotorSaver’s output relay is deactivated after a
specified trip delay. The output relay reactivates after power line
conditions return to acceptable levels for a specified amount of
restart delay time (or a manual reset). The 202 Series includes
advanced single LED diagnostics. Five different light patterns
distinguish between faults and normal conditions. The status
light turns green and the relay is activated when rotation is
correct.
