1. INTRODUCTION
1.1 OVERVIEW
The SR469 Motor Management Relay is a microprocessor based relay designed for the protection and management of medium and
large horsepower motors and driven equipment. The SR469 is equipped with 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. The single line
diagram of Figure 1-1 illustrates the SR469 functionality using the 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
Some of the protection highlights are detailed here, a complete list may be found in Table 1-1. 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 0.25A may be
detected using the 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 4-20mA analog inputs may be used for tripping and alarming on any transducer
input such as vibration, pressure, flow, etc.

OVERVIEW 1. INTRODUCTION

Table 1-1 SR469 PROTECTION FEATURES
Fault diagnostics are provided through pretrip data, event record, trace memory, and statistics. Prior to issuing a trip, the SR469 will take
a snapshot of the measured parameters and store them in a record with the cause of the trip. This pre-trip data may be viewed using the
[NEXT] key before the trip is reset, or by accessing the last trip data of Actual Values page 1. The SR469 event recorder will store up to
40 time and date stamped events including the pre-trip data. Each time a trip occurs, the SR469 will store 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 will enable the operator to pinpoint a problem quickly
and with certainty.
Power metering is built into the SR469 as a standard feature. Table 1-2 outlines the metered parameters that are available to the
operator or plant engineer either through the front panel or through the communications ports. The SR469 is equipped with 3 fully
functional and independent communications ports. The front panel RS232 port may be used for SR469 setpoint programming, local
interrogation or control, and upgrading of SR469 firmware. The Computer RS485 port may be connected to a PLC, DCS, or PC based
man-machine interface program. The Auxiliary RS485 port may be used for redundancy or simultaneous interrogation and/or control
from a second PLC, DCS, or PC program. There are also four 4-20 mA transducer outputs that may be assigned to any measured
parameter. The range of these outputs is scaleable.

1.2ORDER INFORMATION
All features of the SR469 are standard, there are no options. The phase CT secondaries must be specified at the time of order. The
control power and analog output range must also be specified at the time of order. The SR469 differential CT inputs are field
programmable for CTs with 1A or 5A secondaries. There are two ground CT inputs, one for the Multilin 50:0.025 core balance CT and
one for a ground CT with a 1A or 5A 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 SR469 SETUP program is provided
with each unit. A metal demo case may be ordered for demonstration or testing purposes. Other accessories are listed below.

DESCRIPTION
The SR469 is packaged in the standard 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 wiring. Connections in the case are
fitted with mechanisms required to allow the safe removal of the relay unit from an energized panel, such as automatic CT shorting. The
unit is mechanically held in the case by pins on the locking handle, which cannot be fully lowered to the locked position until the electri-
cal connections are completely mated. Any SR469 can be installed in any SR469 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, but it can be cleaned with a damp cloth.
Figure 2-1 SR469 DIMENSIONS
Figure 2-2 SEAL ON DRAWOUT UNIT
To prevent unauthorized removal of the drawout unit,
a wire lead seal can be installed in the slot provided
on the handle as shown in Figure 2-2. 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 still allow monitoring of
actual values. If access to the front panel controls
must be restricted, a separate seal can be installed
on the outside of the cover to prevent it from being
opened.
** WARNING ** Hazard may result if the product is not used for its intended purpose.

INSTALLATION
The SR469 case, alone or adjacent to another SR-series unit, can be installed in the panel of a standard 19 inch rack. (See Figure 2-5 and
Figure 2-6 for panel cutout dimensions.) When mounting, provision must be made for the front door to swing open without interference to, or
from, adjacent equipment. Normally the SR469 unit is mounted in its case when shipped from the factory, and should be removed before
mounting the case in the supporting panel. Unit withdrawal is described in section 2.1.4.
Figure 2-5 SINGLE SR469 CUTOUT PANEL Figure 2-6 DOUBLE SR469 CUTOUT PANEL
After the mounting hole in the panel has been prepared, slide the SR469 case into the panel from the front. Applying firm pressure 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 in Figure 2-7. The case is now securely mounted, ready for panel wiring. If additional support is desired the SR
optional mounting kit may be ordered.

UNIT WITHDRAWAL AND INSERTION
Figure 2-8 PRESS LATCH TO DISENGAGE HANDLE Figure 2-9 ROTATE HANDLE TO STOP POSITION
Figure 2-10 SLIDE UNIT OUT OF THE CASE
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 screwdriver (see
Figure 2-8).
(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 (see Figure 2-9).
(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 2-10).
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.
CAUTION: If an attempt is made to install a unit into a
non-matching case, the mechanical key will prevent full insertion
of the unit. Do not apply strong force in the following step or dam-
age may result.
(4) Grasp the locking handle from the center and press down
firmly, rotating the handle from the raised position toward the bot-
tom of the unit.
(5) When the unit is fully inserted, the latch will be heard to click,
locking the handle in the final position.
