601
1 / 1
Description
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) setpoints are viewable with the 3-digit LED display or from a networked device: low voltage high voltage voltage unbalance low frequency high frequency RS485 address 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 (6) parameters are viewable while 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 RM-1000, RM-2000 or other device.- Part Number
