1 INTRODUCTION 1.1 OVERVIEW
1 INTRODUCTION 1.1 OVERVIEW 1.1.1 DESCRIPTION
The 469 Motor Managemen t Relay is a micropro cessor ba sed rela y design ed for the prote ction and m anagement of medium and large hor sepower motors and driven equipment. Th e 469 is equipped with six output
relays for trips, alar ms, and start blocks. Motor protection, fault diagnosti cs, power metering, and RTU functions are integrated into one ec onomical drawout package. The single-line diagram below illus trates the 469
functionality using ANSI (American National Standards Institute) device numbers.

Figure 1–1: SINGLE LINE DIAGRAM
Typical applications include:
• Pumps • Fans • Compressors
•Mills •Shredders •Extruders
• Debarkers • Refiners • Cranes
• Conveyors • Chillers • Crushers
•Blowers
GE Power Management 469 Motor Management Relay 1-1
1.1 OVERVIEW 1 INTRODUCTION
Some of the protection highlig hts 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
1
a programmable name . The thermal model inc orporates unbalance bia sing, RTD feedback, and exponent ial
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, when the acceleration time exceeds the safe stall time. A second
overload curve is pr ovided for two-speed motors. Ground fau lts 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 protec tion features based on vo ltage and power quantities. F our
4 to 20 mA analog inputs ma y be used for tripping and alarm ing on any transducer input such as vibration,
pressure, flow, etc.

1 INTRODUCTION 1.1 OVERVIEW
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 parame ters and stores them with the cause of the trip. This
pre-trip data may be viewed using the key before the trip i s reset, or by accessing the
LAST TRIP DATA
actual values. The 469 event recorder stores up to 40 time and date stamped events including
NEXT
A1 STATUS /
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 occurrenc es of each type of trip. Minimum an d
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 is buil t into the 469 as a s tandard feature. The ta ble below outline s the metered param eters
available either through the front panel or communications ports.
The 469 is equipped with 3 fully functional and independent communications ports. The front panel RS232 port
may be used for 469 setpoint program ming , loca l interro gation or control , and upgradi ng of 469 fir mware. Th e
Computer RS485 port m ay be connecte d to a PLC, DCS , or PC based u ser interfac e program. The A uxiliary
RS485 port may be used for redundancy or simultaneous interrogat ion 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 assi gne d
to any measured parameter. The range of these outputs is scalable.

1.1 OVERVIEW 1 INTRODUCTION
1.1.2 ORDER INFORMATION
1
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 secondaries. There are two gr ound CT inputs, one for the GE Power Manageme nt 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 configuration. The output relays are always non-failsafe with the
exception of the serv ice relay. The 469PC software is p rovided with each unit. A metal dem o case may be
ordered for demonstration or testing purposes.

2 INSTALLATION 2.1 MECHANICAL 2.1.1 DESCRIPTION
The 469 is packaged in the standard GE Power Management SR series arrangement, which consists of a drawout unit and a co mpanion fixed case. The case provides mechanical protection to the unit and is used to
make permanent con nections to al l external e quipment. The only electric al components mounted in the case
are those required to c onnect the unit to the external wiring. Connections in th e case are fitted with mechanisms required to al low the sa fe r em ov al of th e rel ay uni t fr om an ene rg ized 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 unt il the elec trical con nections ar e complete ly mated. A ny 469 can b e install ed in any 46 9
case, except for c ustom man ufactured un its that a re clearl y identifie d as suc h on both case and unit, and are
equipped with an index pin keying mechanism to prevent incorrect pairings.
No special ventilatio n requirements need to be observed duri ng the installation of the unit. The 469 c an be
cleaned with a damp cloth.

Figure 2–1: DIMENSIONS
To prevent unauthorized re moval of th e drawou t unit, a wire lead seal ca n be ins talled in the s lot provi ded 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.
