  • Page 8 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.

  • Page 9: Introduction

    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.

  • Page 10: Order Information

    1.2 ORDER 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.

  • Page 15: Installation

    2.1.1 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.

  • Page 16: Product Identification

    2.1.2 PRODUCT IDENTIFICATION Each SR469 unit and case are equipped with a permanent label. This label is installed on the left side (when facing the front of the relay) of both unit and case. The case label details which units can be installed.
  • Page 17 2.1.3 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.

  • Page 22: Typical Wiring

    The maximum phase CT primary current is 5000 A. The SR469 will measure correctly up to 20 times the phase current nominal rating. Since the conversion range is large, 1 A or 5 A CT secondaries must be specified at the time of order such that the appropriate interposing CT may be installed in the unit. CTs chosen must be capable of driving the SR469 phase CT burden (see Specifications for ratings).

  • Page 23: Ground Current Input

    The SR469 has a dual primary isolating transformer for ground CT connection. There are no internal ground connections on the ground current inputs. The ground CT circuits are shorted by automatic mechanisms on the SR469 case if the unit is withdrawn. The 1A/5A tap is used either for zero sequence/core balance applications (see Figure 2-12) or residual ground connections where the summation of the three phase current CTs is passed through the ground current input (see Figure 2-14).

  • Page 24: Differential Current Inputs

    The maximum differential CT primary current is 5000 A. The SR469 will measure up to 5 A secondary current for the differential CT inputs. Since the conversion range is relatively small, the 1A or 5A option is field programmable. Proper selection of this setpoint will ensure proper reading of primary phase differential current.

  • Page 25: Voltage Inputs

    2. INSTALLATION ELECTRICAL 2.2.6 VOLTAGE INPUTS The SR469 has three channels for AC voltage inputs, each with an isolating transformer. There are no internal fuses or ground connections on the voltage inputs. The maximum VT ratio is 150.00:1. The two VT connections are open delta (see Figure 2-12) or wye (see Figure 2-19).

  • Page 26: Analog Inputs

    2.2.9 ANALOG OUTPUTS The SR469 provides 4 analog output channels, which when ordering are selected to provide a full-scale range of either 0-1 mA (into a maximum 10 kΩ impedance), or 4-20 mA (into a maximum 1200 Ω impedance). Each channel can be configured to provide full-scale output sensitivity for any range of any measured parameter.

  • Page 27: Rtd Sensor Connections

    2.2.10 RTD SENSOR CONNECTIONS The SR469 can monitor up to 12 RTD inputs for Stator, Bearing, Ambient, or Other temperature monitoring. The type of each RTD is field programmable as: 100Ω Platinum (DIN.43760), 100Ω Nickel, 120Ω Nickel, or 10 Ω Copper. RTDs must be three wire type. Every two RTDs shares a common return.
  • Page 28 Error in temperature readings due to lead and connection resistances. Not recommended for 10C RTDs. If the RTD Return lead to the SR469 or one of the jumpers breaks all RTDs from the point of the break on will read open.
  • Page 29 GROUNDING OF RTDs: If it is required to ground one lead of the RTDs, this can be done at either the SR469 or at the motor. Ground- ing should not be done in both places as it could cause a circulating current to flow. Only RTD Return leads may be grounded.

  • Page 30: Output Relays

    NO contact may be wired in series with the trip relay on a contactor application. This will provide failsafe operation of the motor; that is, the motor will be tripped off line in the event that the SR469 is not protecting it. If however, the process is critical, annunciation of such a failure will allow the operator or the operation computer to either continue, or do a sequenced shutdown.

  • Page 31: Drawout Indicator

    2.2.12 DRAWOUT INDICATOR The Drawout Indicator is simply a jumper from E12 to F12 on the SR469 unit. When the SR469 is withdrawn from the case, terminals E12 and F12 will be open. This may be useful for differentiating between loss of control power as indicated by the R6 SERVICE relay and withdrawal of the unit.

    2.2.15 DIELECTRIC STRENGTH TESTING It may be required to test a complete motor starter for dielectric strength (“flash” or hipot”) with the SR469 installed. The SR469 is rated for 2000Vdc isolation between relay contacts, CT inputs, VT inputs, trip coil supervision, and the safety ground terminal G12. Some precautions are required to prevent SR469 damage during these tests.

    Some of the SR469 characteristics can be modified to suit different situations. Normally "PREFERENCES" will not require changes. DEFAULT MESSAGE CYCLE TIME: If multiple default messages are chosen, the SR469 display will automatically cycle through those messages. The time these messages remain on the display can be changed to accommodate different user reading rates.

  • Page 46: Real Time Clock

    FUNCTION: The SR469 is equipped with 3 serial communications ports supporting a subset of Modbus RTU protocol. The front panel RS232 has a fixed baud rate of 9600, a fixed data frame of 1 start/8 data/1stop/no parity. The front port is intended for local use only and will respond regardless of the slave address programmed.

    50/.025 input, select Multilin 50/.025 for the GROUND CT setpoint. No additional ground CT messages will appear. On solidly grounded systems, where fault currents may be quite large, the SR469 1A or 5A secondary ground CT input should be used for either Zero Se- quence or Residual ground sensing.

  • Page 51: Voltage Sensing

    The SR469 may be used on variable frequency drives when the Nominal System Frequency is chosen as Variable. All of the elements function in the same manner with the following exceptions: the ratio of negative to positive sequence current is calculated from 0–30%, not 40%, and the voltage and power elements will work properly if the voltage waveform is approximately sinusoidal.

  • Page 52: Serial Communication Control

    FUNCTION: The SR469 is capable of controlling the transition of a reduced voltage starter from reduced to full voltage. That transition may be based on Current Only, Current and Time, or Current or Time (whichever comes first). When the SR469 measures the transition of no motor current to some value of motor current, a 'Start' is assumed to be occurring (typically current will rise quickly to a value in excess of FLA e.g.

  • Page 53: S3 Digital Inputs

    Auxiliary ‘a’ contacts or a series combination of Auxiliary ‘b’ contacts from the reduced voltage contactor and the full voltage contactor. Once transition is initiated, the SR469 will assume the motor is still running for at least 2 seconds. This will prevent the SR469 from recognizing an additional start if motor current goes to zero during an open transition.

  • Page 54: Access Switch

    4.4.2 TEST SWITCH Once the SR469 is in service, it may be tested from time to time as part of a regular maintenance schedule. The relay will have accu- mulated statistical information relating historically to starter and motor operation. This information includes: last trip data, demand data (if...

  • Page 55: Starter Status

    Once 'Starter Auxiliary a' is chosen, terminals D16 and D23 will be monitored to detect the state of the breaker or contactor, open sig- nifying the breaker or contactor is open and shorted signifying the breaker or contactor is closed. The SR469 will then determine that a motor has made the transition from 'running' to 'stopped' only when the measured current is less than 5% CT ratio and the 'a' contact is open.

  • Page 64 Figure 4-7 TYPICAL TIME-CURRENT AND THERMAL LIMIT CURVES (ANSI/IEEE C37.96) The motor manufacturer should provide a safe stall time or thermal limit curves for any motor they sell. To program the SR469 for maximum protection, it is necessary to ask for these items when the motor is out for bid. These thermal limits are intended to be used as guidelines and their definition is not always precise.

  • Page 65: S5 Thermal Model

    FUNCTION: The primary protective function of the SR469 is the thermal model. It consists of five key elements: the overload curve and overload pickup level, the unbalance biasing of the motor current while the motor is running, the motor cooling time constants, and the biasing of the thermal model based on Hot/Cold motor information and measured stator temperature.

  • Page 67 If the motor starting times are well within the safe stall times, it is recommended that the SR469 Standard Overload Curve be used. The standard overload curves are a series of 15 curves with a common curve shape based on typical motor thermal limit curves (see Figure 4-8 and Table 4-2).

  • Page 71 The relay that is protecting the motor must be able to distinguish between a locked rotor condition, an accelerating condition and a running condition. The SR469 Volt- age Dependent Overload Curve feature is tailored to protect these types of motors.
  • Page 72 4. SETPOINT PROGRAMMING S5 THERMAL MODEL Construct a custom curve for the running overload thermal limit. If the curve does not extend to the acceleration thermal limits, extend it such that the curve intersects the acceleration thermal limit curves. (see Figure 4-11) Enter the per unit current value for the acceleration overload curve intersect with the custom curve for 80% line voltage.
  • Page 73 The SR469 will take the information provided and create protection curves for any voltage between the minimum and 100%. For values above the voltage in question, the SR469 will extrapolate the safe stall protection curve to 110% voltage. This current level is calculated by taking the locked rotor current @ 100 voltage and multiplying by 1.10.
  • Page 74 Figure 4-14 and Figure 4-15 illustrate the resultant overload protection curves for 80% and 100% line voltage respectively. For voltages in between, the SR469 will shift the acceleration curve linearly and constantly based on measured line voltage during a motor start.

  • Page 75: Unbalance Bias

    The SR469 measures the ratio of negative to positive sequence current. The thermal model may be biased to reflect the additional heating that is caused by negative sequence current when the motor is running. This biasing is done by creating an equivalent motor heating current rather than simply using average current (Iper_unit).

  • Page 76: Motor Cooling

    4.6.5 MOTOR COOLING The SR469 thermal capacity used value is reduced in an exponential manner when the motor current is below the overload pickup set- point. This reduction simulates motor cooling. The motor cooling time constants should be entered for both the stopped and running cases.

  • Page 77: Hot/Cold Curve Ratio

    4.6.7 RTD BIAS The SR469 thermal replica created by the features described in the sections above operates as a complete and independent model. The thermal overload curves however, are based solely on measured current, assuming a normal 40 °C ambient and normal motor cooling.
  • Page 78 4. SETPOINT PROGRAMMING S5 THERMAL MODEL In simple terms, the RTD bias feature is real feedback of measured stator temperature. This feedback acts as correction of the thermal model for unforeseen situations. Since RTDs are relatively slow to respond, RTD biasing is good for correction and slow motor heating. The rest of the thermal model is required during starting and heavy overload conditions when motor heating is relatively fast.

    6.2.2 DATA FRAME FORMAT AND DATA RATE One data frame of an asynchronous transmission to or from an SR469 is default to 1 start bit, 8 data bits, and 1 stop bit. This produces a 10 bit data frame. This is important for transmission through modems at high bit rates (11 bit data frames are not supported by Hayes modems at bit rates of greater than 300 bps).

  • Page 150: Data Packet Format

    Broadcast commands can be used for specific functions. FUNCTION CODE - This is the second byte of every transmission. Modbus defines function codes of 1 to 127. The SR469 implements some of these functions. In a master request transmission the FUNCTION CODE tells the slave what action to perform. In a slave re- sponse transmission if the FUNCTION CODE sent from the slave is the same as the FUNCTION CODE sent from the master indicating the slave performed the function as requested.

  • Page 151: Error Checking

    If an SR469 Modbus slave device receives a transmission in which an error is indicated by the CRC-16 calculation, the slave device will not respond to the transmission. A CRC-16 error indicates than one or more bytes of the transmission were received incorrectly and thus the entire transmission should be ignored in order to avoid the SR469 performing any incorrect operation.

    SR469 Implementation: Read Relay Coil and Digital Input Status For the SR469 implementation of Modbus, these commands can be used to read Relay Coil Status or Digital Input Status. Function 01 The standard implementation requires the following: slave address (one byte), function code (one byte), starting relay coil (two byte), number of coils to read (two bytes), and CRC (two bytes).

  • Page 155: Function Codes 03 And 04 - Read Setpoints And Actual Values

    For the SR469 implementation of Modbus, these commands can be used to read any Setpoint ("holding registers") or Actual Value ("input registers"). Holding and input registers are 16 bit (two byte) values transmitted high order byte first. Thus all SR469 Setpoints and Actual Values are sent as two bytes.

  • Page 156: Function Code 05 - Execute Operation

    SR469 Implementation: Execute Operation This function code allows the master to request an SR469 to perform specific command operations. The command numbers listed in the Commands area of the memory map correspond to operation code for function code 05. The operation commands can also be initiated by writing to the Commands area of the memory map using function code 16. Refer to FUNCTION 16 - STORE MULTIPLE SETPOINTS for complete details.

  • Page 157: Function Code 06 - Store Single Setpoint

    Preset Single Register SR469 Implementation: Store Single Setpoint This command allows the master to store a single setpoint into the memory of an SR469. The slave response to this function code is to echo the entire master transmission. Message Format and Example: Request slave 11 to store the value 01F4 in Setpoint address 1180 After the transmission in this example is complete, Setpoints address 1180 will contain the value 01F4.

The SR469 will echo the request. Message Format and Example: Loopback test from slave 11. Master Transmission Bytes...

  • Page 160: Function Code 16 - Store Multiple Setpoints

    This function code allows multiple Setpoints to be stored into the SR469 memory. Modbus "registers" are 16 bit (two byte) values transmitted high order byte first. Thus all SR469 setpoints are sent as two bytes. The maximum number of Setpoints that can be stored in one transmission is dependent on the slave device.

  • Page 161: Function Code 16 - Performing Commands

    16. To perform this operation using function code 16 (10H), a certain sequence of commands must be written at the same time to the SR469. The sequence consists of : Command Function register, Command operation register and Command Data (if required). The Command Function register must be written with the value of 5 indicating an execute operation is requested.

  • Page 162: Error Responses

    6.4.1 ERROR RESPONSES When an SR469 detects an error other than a CRC error, a response will be sent to the master. The MSbit of the FUNCTION CODE byte will be set to 1 (i.e. the function code sent from the slave will be equal to the function code sent from the master plus 128). The following byte will be an exception code indicating the type of error that occurred.

  • Page 163: Memory Map

    6.5.1 MEMORY MAP INFORMATION The data stored in the SR469 is grouped as Setpoints and Actual Values. Setpoints can be read and written by a master computer. Actual Values are read only. All Setpoints and Actual Values are stored as two byte values. That is, each register address is the ad- dress of a two byte value.

  • Page 164: Waveform Capture

    6.5.4 WAVEFORM CAPTURE The SR469 stores a number of cycles of A/D samples each time a trip occurs in a trace buffer, determined by the setpoint in S1 Prefer- ences, Trace Memory Buffers. The Trace Memory Trigger is set up in S1 Preferences and this determines how many pre-trip and post- trip cycles are stored.

  • Page 258 APPENDIX B APPLICATION NOTES 2φ φ φ φ CT Configuration The purpose of this Appendix is to illustrate how two CT’s may be used to sense three phase currents. The proper configuration for the use of two CTs rather than three to detect phase current is shown. Each of the two CTs acts as a cur- rent source.
  • Page 259 APPLICATION NOTES APPENDIX B Once again, if the polarity of one of the phases is out by 180°, the magnitude of the resulting vector on a balanced system will be out by a factor of 1.73. On a three wire supply, this configuration will always work and unbalance will be detected properly. In the event of a single phase, there will always be a large unbalance present at the interposing CTs of the relay.
