1 INTRODUCTION 1.1 OVERVIEW 1.1.1 DESCRIPTION
The 469 Motor Management Relay is a microprocessor based relay designed for the protection and manage-
ment 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 func-
tions 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:
• Pumps • Fans • Compressors
•Mills •Shredders •Extruders
• Debarkers • Refiners • Cranes
• Conveyors • Chillers • Crushers
•Blowers

1.1 OVERVIEW 1 INTRODUCTION
1Some 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, when 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. Volt-
age 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.

1 INTRODUCTION 1.1 OVERVIEW
1
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 /
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 is built into the 469 as a standard feature. The table below outlines the metered parameters
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 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 measured parameter. The range of these outputs is scalable.

1.1 OVERVIEW 1 INTRODUCTION
11.1.2 ORDER INFORMATION
All 469 features are standard; there are no options. The phase CT secondaries, control power, and analog out-
put 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 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 configuration. 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.
