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.

3.1.1 Mechanical Installation
The 369 is contained in a compact plastic housing with the keypad, display,
communication port, and indicators/targets on the front panel. The unit should be
positioned so the display and keypad are accessible. To mount the relay, make cutout and
drill mounting holes as shown below. Mounting hardware (bolts and washers) is provided
with the relay. Although the relay is internally shielded to minimize noise pickup and
interference, it should be mounted away from high current conductors or sources of
strong magnetic fields.

The 369 can be connected to cover a broad range of applications and wiring will vary
depending upon the user’s protection scheme. This section will cover most of the typical
369 interconnections.
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 3–37
ELECTRICAL INSTALLATION CHAPTER 3: INSTALLATION
In this section, the terminals have been logically grouped together for explanatory
purposes. A typical wiring diagram for the 369 is shown above in FIGURE 3–4: Typical
Wiring for Motor Forward/Reversing Application on page 3–37 and the terminal
arrangement has been detailed in FIGURE 3–3: TERMINAL LAYOUT on page 3–36. For
further information on applications not covered here, refer to Chapter : Applications or
contact the factory for further information.
Hazard may result if the product is not used for intended purposes. This equipment can
only be serviced by trained personnel.
Do not run signal wires in the same conduit or bundle that carries power mains or high
level voltage or currents.
3.3.3 Control Power
VERIFY THAT THE CONTROL POWER SUPPLIED TO THE RELAY IS WITHIN THE RANGE
COVERED BY THE ORDERED 369 RELAY’S CONTROL POWER.
Table 3–1: 369 POWER SUPPLY RANGES
369 POWER SUPPLY AC RANGE DC RANGE
HI 60 to 265 V 50 to 300 V
LO 20 to 48 V 20 to 60 V
The 369 has a built-in switchmode supply. It can operate with either AC or DC voltage
applied to it. The relay reboot time of the 369 is 2 seconds after the control power is
applied. For applications where the control power for the 369 is available from the same
AC source as that of the motor, it is recommended an uninterrupted power supply be used
to power up the relay or, alternatively, use a separate DC source to power up.
Extensive filtering and transient protection has been incorporated into the 369 to ensure
reliable operation in harsh industrial environments. Transient energy is removed from the
relay and conducted to ground via the ground terminal. This terminal must be connected
to the cubicle ground bus using a 10 AWG wire or a ground braid. Do not daisy-chain
grounds with other relays or devices. Each should have its own connection to the ground
bus.
The internal supply is protected via a 3.15 A slo-blo fuse that is accessible for replacement.
If it must be replaced ensure that it is replaced with a fuse of equal size (see FUSE on page
2–13).
3.3.4 Phase Current (CT) Inputs
The 369 requires one CT for each of the three motor phase currents to be input into the
relay. There are no internal ground connections for the CT inputs. Refer to Chapter :
Applications for information on two CT connections.
3–38 369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION ELECTRICAL INSTALLATION
The phase CTs should be chosen such that the FLA of the motor being protected is no less
than 50% of the rated CT primary. Ideally, to ensure maximum accuracy and resolution,
the CTs should be chosen such that the FLA is 100% of CT primary or slightly less. The
maximum CT primary is 5000 A.
The 369 will measure 0.05 to 20 × CT primary rated current. The CTs chosen must be
capable of driving the 369 burden (see specifications) during normal and fault conditions
to ensure correct operation. See Section 7.4: CT Specification and Selection on page –230
for information on calculating total burden and CT rating.
For the correct operation of many protective elements, the phase sequence and CT
polarity is critical. Ensure that the convention illustrated in FIGURE 3–4: Typical Wiring for
Motor Forward/Reversing Application on page 3–37 is followed.
3.3.5 Ground Current Inputs
The 369 has an isolating transformer with separate 1 A, 5 A, and sensitive HGF (50:0.025)
ground terminals. Only one ground terminal type can be used at a time. There are no
internal ground connections on the ground current inputs.
The maximum ground CT primary for the 1 A and 5 A taps is 5000 A. Alternatively the
sensitive ground input, 50:0.025, can be used to detect ground current on high resistance
grounded systems.
The ground CT connection can either be a zero sequence (core balance) installation or a
residual connection. Note that only 1 A and 5 A secondary CTs may be used for the residual
connection. A typical residual connection is illustrated in below. The zero-sequence
connection is shown in the typical wiring diagram. The zero-sequence connection is
recommended. Unequal saturation of CTs, CT mismatch, size and location of motor,
resistance of the power system, motor core saturation density, etc. may cause false
readings in the residually connected ground fault circuit.
FIGURE 3–5: Typical Residual Connection
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 3–39
ELECTRICAL INSTALLATION CHAPTER 3: INSTALLATION
3.3.6 Zero Sequence Ground CT Placement
The exact placement of a zero sequence CT to properly detect ground fault current is
shown below. If the CT is placed over a shielded cable, capacitive coupling of phase current
into the cable shield during motor starts may be detected as ground current unless the
shield wire is also passed through the CT window. Twisted pair cabling on the zero
sequence CT is recommended.
3.3.7 Phase Voltage (VT/PT) Inputs
The 369 has three channels for AC voltage inputs each with an internal isolating
transformer. There are no internal fuses or ground connections on these inputs. The
maximum VT ratio is 240:1. These inputs are only enabled when the metering option (M) is
ordered.
The 369 accepts either open delta or wye connected VTs (see the figure below). The voltage
channels are connected wye internally, which means that the jumper shown on the delta
connection between the phase B input and the VT neutral terminals must be installed.
Polarity and phase sequence for the VTs is critical for correct power and rotation
measurement and should be verified before starting the motor. As long as the polarity
markings on the primary and secondary windings of the VT are aligned, there is no phase
FIGURE 3–6: Zero Sequence CT
3–40 369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION ELECTRICAL INSTALLATION
shift. The markings can be aligned on either side of the VT. VTs are typically mounted
upstream of the motor breaker or contactor. Typically, a 1 A fuse is used to protect the
voltage inputs.
FIGURE 3–7: Wye/Delta Connection
3.3.8 Backspin Voltage Inputs
The Backspin voltage input is only operational if the optional backspin detection (B) feature
has been purchased for the relay. This input allows the 369 to sense whether the motor is
spinning after the primary power has been removed (breaker or contactor opened).
These inputs must be supplied by a separate VT mounted downstream (motor side) of the
breaker or contactor. The correct wiring is illustrated below.
FIGURE 3–8: Backspin Voltage Wiring
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 3–41
ELECTRICAL INSTALLATION CHAPTER 3: INSTALLATION
3.3.9 RTD Inputs
The 369 can monitor up to 12 RTD inputs for Stator, Bearing, Ambient, or Other
temperature applications. The type of each RTD is field programmable as: 100 ohm
Platinum (DIN 43760), 100 ohm Nickel, 120 ohm Nickel, or 10 ohm Copper. RTDs must be
the three wire type. There are no provisions for the connection of thermistors.
The 369 RTD circuitry compensates for lead resistance, provided that each of the three
leads is the same length. Lead resistance should not exceed 25 ohms per lead for platinum
and nickel type RTDs or 3 ohms per lead for Copper type RTDs.
Shielded cable should be used to prevent noise pickup in industrial environments. RTD
cables should be kept close to grounded metal casings and avoid areas of high
electromagnetic or radio interference. RTD leads should not be run adjacent to or in the
same conduit as high current carrying wires.
The shield connection terminal of the RTD is grounded in the 369 and should not be
connected to ground at the motor or anywhere else to prevent noise pickup from
circulating currents.
If 10 ohm Copper RTDs are used special care should be taken to keep the lead resistance
as low as possible to maintain accurate readings.
FIGURE 3–9: RTD Inputs
3.3.10 Digital Inputs
DO NOT CONNECT LIVE CIRCUITS TO THE 369 DIGITAL INPUTS. THEY ARE DESIGNED FOR
DRY CONTACT CONNECTIONS ONLY.
Other than the ACCESS switch input the other 5 digital inputs are programmable. These
programmable digital inputs have default settings to match the functions of the 269Plus
switch inputs (differential, speed, emergency restart, remote reset and spare). However in
addition to their default settings they can also be programmed for use as generic inputs to
set up trips and alarms or for monitoring purposes based on external contact inputs.
Note

3.3.11 Analog Outputs
The 369 provides 1 analog current output channel as part of the base unit and 3 additional
analog outputs with the metering option (M). These outputs are field programmable to a
full-scale range of either 0 to 1 mA (into a maximum 2.4 kΩ impedance) and 4 to 20 mA or
0to20mA (into a maximum 600Ω impedance).
As shown in the typical wiring diagram (FIGURE 3–4: Typical Wiring for Motor Forward/
Reversing Application on page 3–37), these outputs share one common return. Polarity of
these outputs must be observed for proper operation.
Shielded cable should be used for connections, with only one end of the shield grounded,
to minimize noise effects. The analog output circuitry is isolated. Transorbs limit this
isolation to ±36 V with respect to the 369 safety ground.
If an analog voltage output is required, a burden resistor must be connected across the
input of the SCADA or measuring device (see the figure below). Ignoring the input
impedance of the input,
(EQ 3.1)
For 0-1 mA, for example, if 5 V full scale is required to correspond to 1 mA
For 4-20 mA, this resistor would be
3.3.12 Remote Display
The 369 display can be separated and mounted remotely up to 15 feet away from the
main relay. No separate source of control power is required for the display module. A 15
feet standard shielded network cable is used to make the connection between the display
module and the main relay. A recommended and tested cable is available from GE Multilin.
The cable should be wired as far away as possible from high current or voltage carrying
cables or other sources of electrical noise.
(EQ 3.2)
(EQ 3.3)
FIGURE 3–10: Analog Output Voltage Connection
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 3–43
ELECTRICAL INSTALLATION CHAPTER 3: INSTALLATION
In addition the display module must be grounded if mounted remotely. A ground screw is
provided on the back of the display module to facilitate this. A 12 AWG wire is
recommended and should be connected to the same ground bus as the main relay unit.
The 369 relay will still function and protect the motor without the display connected.
3.3.13 Output Relays
The 369 provides four (4) form C output relays. They are labeled Trip, Aux 1, Aux 2, and
Alarm. Each relay has normally open (NO) and normally closed (NC) contacts and can
switch up to 8 A at either 250 V AC or 30 V DC with a resistive load. The NO or NC state is
determined by the ‘no power’ state of the relay outputs.
All four output relays may be programmed for fail-safe or non-fail-safe operation. When in
fail-safe mode, output relay activation or a loss of control power will cause the contacts to
go to their power down state.
Example:
•A fail-safe NO contact closes when the 369 is powered up (if no prior unreset trip
conditions) and will open when activated (tripped) or when the 369 loses control
power.
•A non-fail-safe NO contact remains open when the 369 is powered up (unless a prior
unreset trip condition) and will close only when activated (tripped). If control power is
lost while the output relay is activated (NO contacts closed) the NO contacts will open.
Thus, in order to cause a trip on loss of control power to the 369, the Trip relay should be
programmed as fail-safe. See the figure below for typical wiring of contactors and
breakers for fail-safe and non-fail-safe operation. Output relays remain latched after
activation if the fault condition persists or the protection element has been programmed
as latched. This means that once this relay has been activated it remains in the active state
until the 369 is manually reset.
The Trip relay cannot be reset if a timed lockout is in effect. Lockout time will be adhered to
regardless of whether control power is present or not. The relay contacts may be reset if
motor conditions allow, by pressing the RESET key, using the REMOTE RESET switch or via
communications. The Emergency Restart feature overrides all features to reset the 369.
The rear of the 369 relay shows output relay contacts in their power down state.
Note
In locations where system voltage disturbances cause voltage levels to dip below the
control power range listed in specifications, any relay contact programmed as fail-safe
may change state. Therefore, in any application where the ‘process’ is more critical
3–44 369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL
CHAPTER 3: INSTALLATION ELECTRICAL INSTALLATION
than the motor, it is recommended that the trip relay contacts be programmed as nonfail-safe. If, however, the motor is more critical than the ‘process’ then program the trip
contacts as fail-safe.
FIGURE 3–11: Hookup / Fail and Non-Failsafe Modes
Note
Latched trips and alarms are not retained after control power is removed from the 369
3.3.14 RS485 Communications
Three independent two-wire RS485 ports are provided. If option (F), the fiber optic port , is
installed and used, the COMM 3 RS485 port may not be used. The RS485 ports are isolated
as a group.
Up to 32 369s (or other devices) can be daisy-chained together on a single serial
communication channel without exceeding the driver capability. For larger systems,
additional serial channels must be added. Commercially available repeaters may also be
used to increase the number of relays on a single channel to a maximum of 254. Note that
there may only be one master device per serial communication link.
Connections should be made using shielded twisted pair cables (typically 24 AWG).
Suitable cables should have a characteristic impedance of 120 ohms (e.g. Belden #9841)
and total wire length should not exceed 4000 ft. Commercially available repeaters can be
used to extend transmission distances.
Voltage differences between remote ends of the communication link are not uncommon.
For this reason, surge protection devices are internally installed across all RS485 terminals.
Internally, an isolated power supply with an optocoupled data interface is used to prevent
noise coupling. The source computer/PLC/SCADA system should have similar transient
protection devices installed, either internally or externally, to ensure maximum reliability.
369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL 3–45
ELECTRICAL INSTALLATION CHAPTER 3: INSTALLATION
To ensure that all devices in a daisy-chain are at the same potential, it is imperative
that the common terminals of each RS485 port are tied together and grounded in one
location only, at the master. Failure to do so may result in intermittent or failed
communications.
Correct polarity is also essential. 369 relays must be wired with all ‘+’ terminals connected
together, and all ‘–’ terminals connected together. Each relay must be daisy-chained to the
next one. Avoid star or stub connected configurations. The last device at each end of the
daisy-chain should be terminated with a 120 ohm ¼ watt resistor in series with a 1 nF
capacitor across the ‘+’ and ‘–’ terminals. Observing these guidelines will result in a reliable
communication system that is immune to system transients.

3.4 Remote RTD Module (RRTD)
3.4.1 Mechanical Installation
The optional remote RTD module is designed to be mounted near the motor. This
eliminates the need for multiple RTD cables to run back from the motor which may be in a
remote location to the switchgear. Although the module is internally shielded to minimize
noise pickup and interference, it should be mounted away from high current conductors or
sources of strong magnetic fields.
The remote RTD module physical dimensions and mounting (drill diagram) are shown
below. Mounting hardware (bolts and washers) and instructions are provided with the
module.

4.1.1 Display
All messages are displayed on a 40-character LCD display to make them visible under poor
lighting conditions and from various viewing angles. Messages are displayed in plain
English and do not require the aid of an instruction manual for deciphering. While the
keypad and display are not actively being used, the display will default to user defined
status messages. Any trip, alarm, or start inhibit will automatically override the default
messages and appear on the display.
4.1.2 LED Indicators
There are ten LED indicators, as follows:
• TRIP: Trip relay has operated (energized)
• ALARM: Alarm relay has operated (energized)
• AUX 1: Auxiliary relay has operated (energized)
• AUX 2: Auxiliary relay has operated (energized)
• SERVICE: Relay in need of technical service.
• STOPPED: Motor is in the Stopped condition
• STARTING: Motor is in the Starting condition
• RUNNING: Motor is in the Running condition
• OVERLOAD: Motor is in the Overload condition
• LOCKOUT: Motor is in the Lockout condition

FIGURE 4–1: LED Indicators - Enhanced Faceplate
4.1.3 RS232 Program Port
This port is intended for connection to a portable PC. Setpoint files may be created at any
location and downloaded through this port using the EnerVista 369 Setup software. Local
interrogation of Setpoints and Actual Values is also possible. New firmware may be
downloaded to the 369 Relay flash memory through this port. Upgrading of the relay
firmware does not require a hardware EPROM change.
4.1.4 Keypad
The 369 Relay messages are organized into pages under the main headings, Setpoints and
Actual Values. The [SETPOINTS] key is used to navigate through the page headers of the
programmable parameters. The [ACTUAL VALUES] key is used to navigate through the
page headers of the measured parameters.
Each page is broken down further into logical subgroups of messages. The [PAGE] up and
down keys may be used to navigate through the subgroups.
• [SETPOINTS]: This key may be used to navigate through the page headers of the
programmable parameters. Alternately, one can press this key followed by using
the Page Up / Page Down keys.
• [ACTUAL VALUES]: This key is used to navigate through the page headers of the
measured parameters. Alternately, one can scroll through the pages by pressing
the Actual Values key followed by using the Page Up / Page Down keys.
FIGURE 4–2: LED Indicators - Basic Faceplate
4–58 369 MOTOR MANAGEMENT RELAY– INSTRUCTION MANUAL
CHAPTER 4: USER INTERFACES FACEPLATE INTERFACE
• [PAGE]: The Page Up/ Page Down keys may be used to scroll through page headers
for both Setpoints and Actual Values.
• [LINE]: Once the required page is found, the Line Up/ Line Down keys may be used
to scroll through the sub-headings.
• [VALUE]: The Value Up and Value Down keys are used to scroll through variables in
the Setpoint programming mode. It will increment and decrement numerical
Setpoint values, or alter yes/no options.
• [RESET]: The reset key may be used to reset a trip or latched alarm, provided it has
been activated by selecting the local reset.
• [ENTER] The key is dual purpose. It is used to enter the subgroups or store altered
setpoint values.
• [CLEAR] The key is also dual purpose. It may be used to exit the subgroups or to
return an altered setpoint to its original value before it has been stored.
• [HELP]: The help key may be pressed at any time for context sensitive help
messages; such as the Setpoint range, etc.
To enter setpoints, select the desired page header. Then press the [LINE UP] / [LINE DOWN]
keys to scroll through the page and find the desired subgroup. Once the desired subgroup
is found, press the [VALUE UP] / [VALUE DOWN] keys to adjust the setpoints. Press the
[ENTER] key to save the setpoint or the [CLEAR] key to revert back to the old setpoint.
4.1.5 Setpoint Entry
In order to store any setpoints, Terminals 57 and 58 (access terminals) must be shorted (a
key switch may be used for security). There is also a Setpoint Passcode feature that may be
enabled to restrict access to setpoints. The passcode must be entered to allow the
changing of setpoint values. A passcode of 0 effectively turns off the passcode feature and
only the access jumper is required for changing setpoints.
If no key is pressed for 30 minutes, access to setpoint values will be restricted until the
passcode is entered again. To prevent setpoint access before the 30 minutes expires, the
unit may be turned off and back on, the access jumper may be removed, or the
ACCESS
terminals 57 and 58 (access terminals) are shorted.
Setpoint changes take effect immediately, even when motor is running. It is not
recommended, however, to change setpoints while the motor is running as any mistake
could cause a nuisance trip.
Refer to Section 5.2.1: Setpoint Access on page –111 for a detailed description of the
setpoint access procedure.
SETPOINT
setpoint may be changed to Restricted. The passcode cannot be entered until
