The Model 601
is a fully-programmable voltage monitor designed to protect 3-phase motors. It can be used as a standalone product or networked with an RM-1000, RM-2000, PLC, computer or SCADA system.  When a harmful condition is detected, the MotorSaver’s output relay is deactivated after the specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for the programmed restart delay (RD2).  The following 11 setpoints can be viewed from the 3-digit LED display or from a networked device: low voltage, high voltage, voltage unbalance, low frequency, high frequency, trip delay for voltage/frequency faults, trip delay for single-phase faults, rapid-cycle timer (RD1), restart delay after all faults (RD2), type of restart after all faults (manual or automatic), and RS-485 address. Six parameters can be viewed as the motor is running: L1-L2 voltage, L2-L3 voltage, L1-L3 voltage, average voltage, percent voltage unbalance and frequency.
