GE FANUC 369 Motor Management Relay

GE FANUC 369 Motor Management Relay

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 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’s protective capabilities.

The 369 offers optimum motor protection where other relays cannot, by using the FlexCurve™ custom overload curve, or

one of the fifteen standard curves.

The 369 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 369PC software and a computer. Status, actual values and

troubleshooting information are also available via the front panel display or via communications. A simulation mode and

pickup indicator allow testing and verification of correct operation without requiring a relay test set.

As an option, the 369 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 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 to detect the flow reversal of a pump motor and enable timely and safe

motor restarting. 369 options are available when ordering the relay or as upgrades to the relay in the field. Field upgrades

are via an option enabling passcode available from GE Power Management, which is unique to each relay and option.

Notes: One Analog Output is now 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 9 digits. The 369 is available in a non-drawout version only.

Examples: 369-HI-R-0-0-0 369 with HI voltage control power and 12 RTD inputs
