The Model 601
is a fully-programmable voltage monitor designed
to protect 3-phase motors. It can be used as a stand-
alone 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.
When used with the RS485MS-2W communications
module, the Model 601 can communicate with most
modbus RTU master devices. Voltage conditions
can be monitored and setpoints can be changed
remotely using SymCom’s Solutions software, an
RM-1000, RM-2000 or other device.

drawing.
