Model 777-KW/HP - SymCom

Model 601The Model 601is 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 isdeactivated after the specified trip delay. The output relay reactivates afterpower line conditions return to an acceptable level for the programmedrestart delay (RD2).Available Models:601601-HVR601-575The following 11 setpoints can be viewed from the 3-digit LED display orfrom a networked device: low voltage, high voltage, voltage unbalance, lowfrequency, high frequency, trip delay for voltage/frequency faults, trip delay forsingle-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. Sixparameters 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 or 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 remotelyusing SymCom’s Solutions software, an RM-1000, RM-2000, or other device.See Appendix A, Figure 23 for a typical wiring diagram.SpecificationsNominal Input Voltage601 • • • • • • • • • • • • • • • • • • • • • • 190-480VAC601-HVR • • • • • • • • • • • • • • • • • • 380-480VAC601-575 • • • • • • • • • • • • • • • • • • • 500-600VACFrequency • • • • • • • • • • • • • • • • • 50*/60HzProgrammable Operating PointsLV - Low Voltage Threshold • • • • • • • 170V (450V**) - HV SettingHV- High Voltage Threshold • • • • • • • LV Setting - 528V (660V**)VUB - Voltage Unbalance Threshold• • 2-15% or offLF - Low Frequency Threshold • • • • • 35Hz - HF SettingHF - High Frequency Threshold • • • • LF Setting - 75HzTD1 - Trip Delay for Voltage/Unbalance/Frequency Faults• • • • • • 1-50 secondsTD2 - Trip Delay forSingle-Phase Faults• • • • • • • • • • • • 1-50 secondsRD1 - Rapid-Cycle Timer • • • • • • • • 0, 2-500 secondsRD2 - Restart Delay After All Faults • 2-500 seconds#RF - Type of Restart• • • • • • • • • • • Manual or AutomaticADDR - RS-485 Address • • • • • • • • A01-A99Fixed Reset PointsOvervoltage Reset • • • • • • • • • • • • 97% of HV SettingLow Voltage Reset • • • • • • • • • • • • • 103% of LV SettingVoltage Unbalance Reset• • • • • • • • • UB Setting -1%Low Frequency Reset• • • • • • • • • • • LF Setting +0.6HzHigh Frequency Reset • • • • • • • • • • HF Setting -0.6HzPhysical SpecificationsOutput Contact Rating601, 601-575 • • • • • • • • • • • • • • • • 480VA @ 240VAC (Pilot Duty)601-HVR • • • • • • • • • • • • • • • • • • 470VA @ 600VAC (Pilot Duty)Transient Protection (Internal) • • • • • 2500 V for 10 msAccuracyVoltage • • • • • • • • • • • • • • • • • • • • ±1%Timing • • • • • • • • • • • • • • • • • • • • 5% ±1 secondRepeatabilityVoltage • • • • • • • • • • • • • • • • • • • • ±0.5%Temperature Range • • • • • • • • • • 0° to 70°CDimensions • • • • • • • • • • • • • • • • 3.0" H x 5.1" D x 3.6" WPower Consumption • • • • • • • • • 5 Watts (max.)Weight • • • • • • • • • • • • • • • • • • • 1.2 lbs.SymCom's Model 601 can be preprogrammed prior to installation byapplying at least 120V to the L1 and L2 terminals.*Note: 50Hz will increase all delay timers by 20%**575V Model26 www.symcom.com • tel: 605-348-5580 800-843-8848 • fax: 605-348-5685
