GE 369 Motor Management Relay

GE 369 Motor Management Relay

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.

Features available only in Enhanced option (E)

Relay Label Definition

1. The 369 Relay order code at the time of leaving the factory. 

2. The serial number of the 369 Relay. 

3. The firmware installed at the factory. Note that this may no longer be the currently  installed firmware as it may have been upgraded in the field. The current firmware revision can be checked in the actual values section of the 369 Relay. 

4. Specifications for the output relay contacts. 

5. Certifications the 369 Relay conforms with or has been approved to. 

6. Factory installed options. These are based on the order code. Note that the 369 Relay  may have had options upgraded in the field. The actual values section of the 369 can  be checked to verify this. 

7. Control power ratings for the 369 Relay as ordered. Based on the HI/LO rating from  the order code. 

8. Pollution degree. 

9. Overvoltage category. 

10. IP code. 

11. Modification number for any factory-ordered mods. 

12. Insulative voltage rating.
