Introduction
1.1 Ordering
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 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 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 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 Multilin, which is unique to each relay and option.

CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION
369 MOTOR MANAGEMENT RELAY – QUICKSTART GUIDE 2–11
2.3.2 Typical Wiring
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.
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 2–4: Typical
Wiring on page 2–10 and the terminal arrangement has been detailed in FIGURE 2–3:
TERMINAL LAYOUT on page 2–9. For further information on applications not covered here,
refer to the 369 Instruction Manual, 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.
2.3.3 Control Power
VERIFY THAT THE CONTROL POWER SUPPLIED TO THE RELAY IS WITHIN THE RANGE
COVERED BY THE ORDERED 369 RELAY’S CONTROL POWER.
The 369 has a built-in switchmode supply. It can operate with either AC or DC voltage
applied to it.
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
5–60).
2.3.4 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.

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

2–12 369 MOTOR MANAGEMENT RELAY – QUICKSTART GUIDE
ELECTRICAL INSTALLATION CHAPTER 2: 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.
2.3.5 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:
•Afail-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.
•Anon-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
than the motor, it is recommended that the trip relay contacts be programmed as non-
fail-safe. If, however, the motor is more critical than the ‘process’ then program the trip
contacts as fail-safe.
2.3.6 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.

CHAPTER 2: INSTALLATION ELECTRICAL INSTALLATION
369 MOTOR MANAGEMENT RELAY – QUICKSTART GUIDE 2–13
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.
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.
