Littelfuse 601575 Voltage Monitor Description
The model 601 is a fully-programmable voltage monitor designed to protect 3-phase motors from loss of any phase (single-phasing), phase reversal, low or high voltage, voltage unbalance, low or high frequency, and rapid cycling. It can be
used as a stand-alone product or networked with an RM1000, RM2000, PLC, computer or SCADA system.
When a harmful condition is detected, the 601’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)
Eleven (11) parameters can be viewed from the three 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).
Six parameters can be viewed as the motor is running:
•L1-L2 Voltage •L2-L3 Voltage •L1-L3 Voltage •Average Voltage •Voltage
Unbalance(%) •Voltage Frequency (%).
When used with the RS485MS-2W communications module, the 601 can communicate with most Modbus RTU master devices. Voltage conditions can be monitored and setpoints can
be changed remotely using Solutions software, an RM1000, RM2000 or other device.
