369 Motor Management Relay
Chapter 1: Introduction

Introduction

1.1.1 General Overview

The 369 Motor Management Relay is a digital relay that provides protection and monitoring for three phase motors and their associated mechanical systems. A unique feature of the 369 Relay is its ability to ‘learn’ individual motor parameters and to adapt itself to each application. Values such as motor inrush current, cooling rates and acceleration time may be used to improve the 369 Relay’s protective capabilities.
The 369 Relay offers optimum motor protection where other relays cannot, by using the FlexCurve™ custom overload curve, or one of the fifteen standard curves.
The 369 Relay has one RS232 front panel port and three RS485 rear ports. The Modbus RTU protocol is standard to all ports. Setpoints can be entered via the front keypad or by using the EnerVista 369 Setup software and a computer. Status, actual values and troubleshooting information are also available via the front panel display or via communications.
As an option, the 369 Relay can individually monitor up to 12 RTDs. These can be from the stator, bearings, ambient or driven equipment. The type of RTD used is software selectable. Optionally available as an accessory is the remote RTD module which can be linked to the 369 Relay via a fibre optic or RS485 connection.
The optional metering package provides VT inputs for voltage and power elements. It also provides metering of V, kW, kvar, kVA, PF, Hz, and MWhrs. Three additional user configurable analog outputs are included with this option along with one analog output included as part of the base unit.
The Back-Spin Detection (B) option enables the 369 Relay to detect the flow reversal of a pump motor and enable timely and safe motor restarting. All 369 Relay options are available when ordering the relay from the factory. Field upgrades are only available for the relay when the required hardware is installed in the relay from the factory. Field
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 1–1
ORDERING CHAPTER 1: INTRODUCTION
upgrades are via an option enabling passcode available from GE Multilin, which is unique to each relay and option. Any hardware modifications made to the relay in the field will void the product warranty and will not be supported by GE Multilin.

NoteNotes:
1. One Analog Output is available with the 369 base model. The other three Analog
Outputs can be obtained by purchasing the metering or backspin options.
The control power (HI or LO) must be specified with all orders. If a feature is not required, a 0 must be placed in the order code. All order codes have 10 digits. The 369 is available in a non-drawout version only.
Examples: 369-HI-R-0-0-0-0-E: 369 with HI voltage control power and 12 RTD inputs, and enhanced diagnostics 369-LO-0-M-0-0-0-E: 369 relay with LO voltage control power and metering option, and enhanced diagnotics
2. Features available only in Enhanced option (E)
• Enhanced faceplate with motor status indicators
• Motor Health Report
• Enhanced learned data
• Motor Start Data Logger
• Enhanced event recorder
• Security audit trail events

• mechanical jam / stall
• two-speed motor protection
Optional functions include:
• under / overvoltage (27/59)
•phase reversal (47)
• underpower (37)
• power factor (55)
• stator / bearing overtemperature with twelve (12) independent RTD inputs (49/38)
• backspin detection
Management functions include:
• statistical data
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 2–9
• pre-trip data (last 40 events)
• ability to learn, display and integrate critical parameters to maximize motor protection
• a keypad with 40 character display
• flash memory
The relay is capable of displaying important metering functions, including phase volt­ages, kilowatts, kvars, power factor, frequency and MWhr. In addition, undervoltage and low power factor alarm and trip levels are field programmable. The communica­tions interface include one front RS232 port and three independent rear RS485 ports with supporting PC software, thus allowing easy setpoint programming, local retrieval of information and flexibility in communication with SCADA and engineering worksta­tions.
