369 Motor Protection System :: GE Grid Solutions

	Key Features

	Enhanced thermal model Stall / Jam protection Undervoltage, overvoltage Underfrequency Thermal overload Undercurrent/current unbalance		Variable lockout time Overtemperature 12 RTDs (R option) Starts/hour, time between starts Voltage Phase Reversal (M option) Current based phase reversal Undervoltage Auto-restart

	Protection & Control
	The 369 is a digital motor protection system designed to protect and manage medium sized AC motors and their driven equipment. It contains a full range of selectively enabled, self contained protection and control elements as detailed in the Functional Block Diagram and Features table.

	Key Features

	Metering - current, voltage, power, energy, frequency, RTD Temperature, Remote RTD Fault diagnosis, - Event Record, Oscillography, Motor Starting Data Logger Motor Health Report Statistical information & learned motor data Voltage/frequency/power display (M option) 4 analog outputs (M option)

Monitoring & Metering

The 369 offers a choice of optional monitoring and metering functions including:

Actual Values
Metering (Option M)
Pre-Trip Alarms
Event Recorder
Oscillography

Statistical Data
Learned Information
Motor Start Data Logger
Testing

	Track changes in motor starting characteristics, identifying potential failures before they become critical Troubleshoot faults that occur during motor starts using the Motor Start Data logger.

	Key Features

	Front Panel RS232 port for programming and troubleshooting Optional embedded Ethernet port Optional Profibus DP/DPV1 or DeviceNet via dedicated port Multiple Protocols - Modbus RTU, Modbus TCP/IP

A front RS232 port is provided for downloading setpoints and interrogating the relay using the EnerVista™ 369.
Three independent rear RS485 ports offer the customer flexibility and performance for their communication network. The 369 can
communicate at baud rates up to 19,200 bps using the industry standard Modbus® RTU protocol. Fiber optic (option F) Profibus interface
(option P), DeviceNet (option D), and Ethernet (option E) ports are also available. The optional direct connect RJ45 Ethernet port
can be used to connect the 369 to 10 Mbps Ethernet networks. The communication system of the 369 is designed to allow simultaneous
communication via all ports.

Using Ethernet as the physical media to integrate the 369 to Local or Wide Area Networks replaces a multipoint wired
network (e.g., serial Modbus®), and eliminates expensive leased or dial-up connections, reducing operating costs.

Front Panel

Display
40 Character LCD display for viewing actual values and programming setpoints

Status Indicators
4 LEDs indicate when an output is activated

Motor Status Indicators
LEDs indicated if motor Stopped, Starting, Running, Overloaded or Locked out due to an active Satart Inhibit element

Keypad
Used to display actual values, causes of alarms, causes of trips, fault diagnosis information, and to program setpoints

Computer Interface
RS232 comm part for connecting to a PC, Use for downloading setpoints, monitoring, data collection & printing reports

	EnerVista™ Software
	The EnerVista™ Suite is an industry leading set of software programs that will simplify every aspect of using the 369 relay. Tools to monitor the status of the motor, maintain the relay, and integrate information measured by the 369 into HMI or SCADA monitoring systems are available. Also provided are the utilities to analyze the cause of faults and system disturbances using the powerful waveform and Sequence of Event viewers that come with the EnerVista™ 369 Setup Software that is included with each relay.
