GE-369 Motor Management Relay

GE-369 Motor Management Relay

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

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. 1.1.2 Ordering Select the basic model and the desired features from the selection guide below: 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
