Quick Reference Guide
This Quick Reference Guide takes you through the installation and setup of your GE
Multilin 469 Motor Management Relay, and helps you get setup and running as quickly as
possible. The following topics are covered:
• Installing the 469 relay
• Installing the EnerVista 469 Setup software
• Configuring the 469 relay
This guide contains only basic instructions. For complete information, refer to GE
publication GEK-106474C: 469 Motor Management Relay Instruction Manual.

1Description
The 469 Motor Management Relay is a microprocessor-based relay designed for the
protection and management of medium and large horsepower motors and driven
equipment. The 469 is equipped with six (6) output relays for trips, alarms, and start blocks.
Motor protection, fault diagnostics, power metering, and RTU functions are integrated into
one economical drawout package.
Typical applications include: pumps, fans, compressors, mills, shredders, extruders,
debarkers, refiners, cranes, conveyors, chillers, crushers, and blowers. Some of the
protection highlights are detailed here; a complete list is shown below.
Four assignable digital inputs may be configured for a number of different features
including tachometer or generic trip and alarm with a programmable name. The thermal
model incorporates unbalance biasing, RTD feedback, and exponential cooling. In addition
to the 15 standard overload curves, there is a custom curve feature and a curve
specifically designed for the starting of high inertia loads (where the acceleration time
exceeds the safe stall time). A second overload curve is provided for two-speed motors.
Ground faults or earth leakage as low as 0.25 A may be detected using the GE Multilin
50:0.025 ground CT. CT inputs for phase differential protection are also provided. The 12
RTD inputs provided may be individually field programmed for different RTD types. Voltage
transformer inputs allow for numerous protection features based on voltage and power
quantities. Four 4 to 20 mA analog inputs may be used for tripping and alarming on any
transducer input such as vibration, pressure, flow, etc.
Each relay provides protection, control, and monitoring functions with both local and
remote human interfaces. They also display the present trip/alarm conditions, and
measured system parameters. Recording of past trip, alarm or control events, maximum
demand levels, and energy consumption is also performed.
To aid new users in getting basic protection operating quickly, setpoints are set to typical
default values and advanced features are disabled. These settings can be reprogrammed
at any time.

Programming can be accomplished via the front panel. To simplify programming and
provide a more intuitive interface, setpoints can also be entered with a PC running the no-
charge EnerVista 469 setup software provided with the relay. Actual values and setpoints
can be displayed, altered, stored, and printed. If settings are stored in a setpoint file, they
can be downloaded at any time to the front panel program port of the relay via a
computer cable connected to the serial port of any personal computer.

2 Mechanical installation
2.1 Drawout case
The 469 is packaged in the standard SR-series arrangement, which consists of a drawout
relay and a companion case. The case provides mechanical protection for the drawout
portion and is used to make permanent electrical connections to external equipment.
Where required, case connectors are fitted with mechanisms, such as automatic CT
shorting, to allow the safe removal of the relay from an energized panel. There are no
electronic components in the case.
FIGURE 2: Case Dimensions
2.2 Mounting
The 469 can be mounted alone or adjacent to another SR-series unit on a standard 19-
inch rack panel. The dimensions of the panel cutout are shown below. When planning the
location of the panel cutout, ensure provision is made for the front door to swing open
without interference to or from adjacent equipment.

FIGURE 3: Single and double unit panel cutouts
Before mounting the 469 in the supporting panel, remove the unit from the case.
From the front of the panel, slide the empty case into the cutout. To ensure the front bezel
sits flush with the panel, apply pressure to the bezel front while bending the retaining tabs
90°. These tabs are located on the sides and bottom of the case and appear as shown
below. After bending all tabs, the case will be securely mounted and the relay can be
inserted. The SR unit is now ready for panel wiring.

2.3 Unit withdrawal
Turn off control power before drawing out or reinserting the relay to prevent
maloperation!
If an attempt is made to install a relay into a non-matching case, the case's
configuration pin will prevent full insertion. Applying a strong force in this instance will
result in damage to the relay and case.
To remove the unit from the case:
1. Open the door by pulling from the top or bottom of its right side. It will rotate to the left
about its hinges.
2. Press upward on the locking latch, which is located below the handle, and hold in its
raised position. The tip of a small screwdriver may prove helpful in this operation.
FIGURE 5: Press latch up and pull handle
3. With the latch raised, pull the center of the handle outward. Once disengaged,
continue rotating the handle up to the stop position.
FIGURE 6: Rotating handle to stop position
4. When the stop position is reached, the locking mechanism will release. The relay will
now slide out of the case when pulled from its handle. To free the relay, it may
sometimes be necessary to adjust the handle position slightly.
