1 INTRODUCTION 1.1OVERVIEW 1.1.1 DESCRIPTION
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 output relays for trips, alarms,
and start blocks. Motor protection, fault diagnostics, power metering, and RTU functions are integrated into one economical
drawout package. The single-line diagram below illustrates the 469 functionality using ANSI (American National Standards
Institute) device numbers.
Figure 1–1: SINGLE LINE DIAGRAM
Typical applications include:
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,

1when 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 Power Management 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 quanti-
ties. Four 4 to 20 mA analog inputs may be used for tripping and alarming on any transducer input such as vibration, pres-
sure, flow, etc.
Figure 1–2: PROTECTION FEATURES
Fault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the
469 takes a snapshot of the measured parameters and stores them with the cause of the trip. This pre-trip data may be
viewed using the key before the trip is reset, or by accessing the A1 STATUS Õ× LAST TRIP DATA actual values. The
469 event recorder stores up to 40 time and date stamped events including the pre-trip data. Each time a trip occurs, the
469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip for all measured AC quantities. Trip counters record the number
of occurrences of each type of trip. Minimum and maximum values for RTDs and analog inputs are also recorded. These
features enable the operator to pinpoint a problem quickly and with certainty.
Power metering included with the 469 as a standard feature. The table below outlines the metered parameters available
either through the front panel or communications ports.

GE Multilin 469 Motor Management Relay 1-3
1 INTRODUCTION 1.1 OVERVIEW
1
The 469 is equipped with 3 fully functional and independent communications ports. The front panel RS232 port may be
used for 469 setpoint programming, local interrogation or control, and upgrading of 469 firmware. The Computer RS485
port may be connected to a PLC, DCS, or PC based user interface program. The Auxiliary RS485 port may be used for
redundancy or simultaneous interrogation and/or control from a second PLC, DCS, or PC software.
There are also four 4 to 20 mA or 0 to 1 mA (as specified with order) transducer outputs that may be assigned to any mea-
sured parameter. The range of these outputs is scalable. Additional features are outlined in the table below.
1.1.2 ORDER INFORMATION
All 469 features are standard; there are no options. The phase CT secondaries, control power, and analog output range
must be specified at the time of order. The 469 differential CT inputs are field programmable for CTs with 1 A or 5 A second-
aries. There are two ground CT inputs, one for the GE Power Management 50:0.025 core balance CT and one for a ground
CT with a 1 A or 5 A secondary, also field programmable. The VT inputs will accommodate VTs in either a delta or wye con-
figuration. The output relays are always non-failsafe with the exception of the service relay. The 469PC software is provided
with each unit. A metal demo case may be ordered for demonstration or testing purposes.
For example, the 469-P1-LO-A20 code specifies a 469 Motor Management Relay with 1 A CT Inputs, 25 to 60 V DC or 20
to 48 V AC control voltage, and 4 to 20 mA Analog Outputs. Other accessories are shown below:
•469PC Software: Provided free with each relay
•DEMO: Metal Carry Case in which 469 unit may be mounted
•SR 19-1 PANEL: Single cutout 19" panel; SR 19-2 PANEL: Dual cutout 19" panel
•SCI MODULE: RS232 to RS485 converter box designed for harsh industrial environments
•Phase CT: 50, 75, 100, 150, 200, 250, 300, 350, 400, 500, 600, 750, 1000
•HGF3, HGF5, HGF8: For sensitive ground detection on high resistance grounded systems.
•469 1" Collar: For shallow switchgear, reduces the depth of the relay by 1 #3/8"
•469 3" Collar: For shallow switchgear, reduces the depth of the relay by 3"

2 INSTALLATION 2.1MECHANICAL 2.1.1 DESCRIPTION
The 469 is packaged in the standard GE Multilin SR series arrangement, which consists of a drawout unit and a companion
fixed case. The case provides mechanical protection to the unit and is used to make permanent connections to all external
equipment. The only electrical components mounted in the case are those required to connect the unit to the external wir-
ing. Connections in the case are fitted with mechanisms required to allow the safe removal of the relay unit from an ener-
gized panel (for example, automatic CT shorting). The unit is mechanically held in the case by pins on the locking handle
that cannot be fully lowered to the locked position until the electrical connections are completely mated. Any 469 can be
installed in any 469 case, except for custom manufactured units that are clearly identified as such on both case and unit,
and are equipped with an index pin keying mechanism to prevent incorrect pairings.
No special ventilation requirements need to be observed during the installation of the unit. The 469 can be cleaned with a
damp cloth.
Figure 2–1: DIMENSIONS
To prevent unauthorized removal of the drawout unit, a wire lead seal can be installed in the slot provided on the handle.
With this seal in place, the drawout unit cannot be removed. A passcode or setpoint access jumper can be used to prevent
entry of setpoints but allow monitoring of actual values. If access to the front panel controls must be restricted, a separate
seal can be installed on the cover to prevent it from being opened.
Hazard may result if the product is not used for its intended purpose.

2.1.3 INSTALLATION
The 469 case, alone or adjacent to another SR series unit, can be installed in the panel of a standard 19-inch rack (see the
diagram below for panel cutout dimensions). Provision must be made when mounting for the front door to swing open with-
out interference to, or from, adjacent equipment. Normally the 469 unit is mounted in its case when shipped from the fac-
tory, and should be removed before mounting the case in the supporting panel. Unit withdrawal is described in the next
section.
Figure 2–4: SINGLE AND DOUBLE 469 CUTOUT PANELS
After the mounting hole in the panel has been prepared, slide the 469 case into the panel from the front. Applying firm pres-
sure on the front to ensure the front bezel fits snugly against the front of the panel, bend out the pair of retaining tabs (to a
horizontal position) from each side of the case as shown below. The case is now securely mounted, ready for panel wiring.
If additional support is desired, the SR optional mounting kit may be ordered.

2.1.4 UNIT WITHDRAWAL AND INSERTION
TURN OFF CONTROL POWER BEFORE DRAWING OUT OR RE-INSERTING THE RELAY TO PREVENT MAL-
OPERATION!
If an attempt is made to install a unit into a non-matching case, the mechanical key will prevent full inser-
tion of the unit. Do not apply strong force in the following step or damage may result.
To remove the unit from the case:
1. Open the cover by grasping the center of the right side and then pulling the cover, which will rotate about the hinges on
the left.
2. Release the locking latch, located below the locking handle, by pressing upward on the latch with the tip of a screw-
driver.
Figure 2–6: PRESS LATCH TO DISENGAGE HANDLE
3. While holding the latch raised, grasp the locking handle in the center and pull firmly, rotating the handle up from the
bottom of the unit until movement ceases.

4. Once the handle is released from the locking mechanism, the unit can freely slide out of the case when pulled by the
handle. It may sometimes be necessary to adjust the handle position slightly to free the unit.
Figure 2–8: SLIDE UNIT OUT OF CASE
To insert the unit into the case:
1. Raise the locking handle to the highest position.
2. Hold the unit immediately in front of the case and align the rolling guide pins (near the hinges of the locking handle) to
the guide slots on either side of the case.
3. Slide the unit into the case until the guide pins on the unit have engaged the guide slots on either side of the case.
4. Grasp the locking handle from the center and press down firmly, rotating the handle from the raised position toward the
bottom of the unit.
5. When the unit is fully inserted, the latch will be heard to click, locking the handle in the final position.
No special ventilation requirements need to be observed during the installation of the unit. The unit does
not require cleaning.
