　　Product Description

The SR469-P5-HI-A20-E is from GE Multilin and is part of the SR 469 Motor Management Relay line. This unit is designed with 5 amp phase CT secondaries. Designed for use with medium-voltage motors, SR 469 relays offer integrated management and protection. AX Control maintains on-hand stock of a number of different Multilin SR 469 relays.　　The SR469-P5-HI-A20-E offers 70-265 VAC, 90-300 VDC control power. This unit has an enhanced front panel. However, if you need a unit that can be used within a harsh environment, please refer to our listing for the SR469-P5-HI-A20-E-H, which is like this unit in every way with the exception of an additional harsh environment conformal coating.

 

 

The SR469-P5-HI-A20-E has a well-designed front panel that offers ease of use. The panel includes an RS-232 program port interface with a 9600 baud rate, programmable up to 19,200 baud. This panel has a draw-out handle that can be sealed to prevent any sort of unauthorized removal. The front panel has a large LCD display with forty character capabilities. Users can see diagnostic messages like trips or alarms locally through this display. Additionally, the panel has motor and output status indicators, unit indicators, a numeric keypad, control and programming keys, including a reset, escape, and menu button, and value keys that will allow users to change setpoint values.　　GE Multilin manuals and user guides will provide further details about this unit, including information regarding installation,

 

 

handling, safety, and maintenance. AX Control can help with replacement manuals if you no longer have your originals.　　Frequently Asked Questions about SR469-P5-HI-A20-E　　What should be done about unbalanced bias of thermal capacity’s and bias K factors with a GE SR469-P5-HI-A20-E Motor Management Relay?　With a GE SR469-P5-HI-A20-E Motor Management Relay having an unbalaned bias of thermal capacity’s, it should be enabled to the thermal capacity usage so the heating effect of the unbalanced bias currents are added to the thermal capacity. With an unbalanced bias K factor the value is calculated by the contribution of the negative current that flows in the rotor due to the unbalance of the K factor. There is a formula that is based on data stats that are empirical to the letter “K”, and it is equal to 230 divided by the per unit locked rotor current that is all squared. The locked rotor amps = 631 percent FLA or 6.31 multiplied by the FLA.　　The SR469-P5-HI-A20-E-H, from GE Multilin, is one of the company’s SR 469 motor management relays. AX Control has a number of these devices in stock and ready to ship at a moment’s notice. SR 469 motor management relays are primarily used for thermal protection.

 

 

The SR469-P5-HI-A20-E-H includes a conformal coating for harsh environments. This coating will extend the working life of the relay and is recommended for units going into environments where specific hazards exist. This may include corrosive agents, hydrogen sulfide, or high humidity levels.　　SR469 relays were designed to offer comprehensive motor protection. They have multiple RTD inputs; these are used for stator thermal protection. The units include simulation functions, event reports, data logging, and waveform capture. Additionally, SR469 relays offer complete asset monitoring, including analog I/o, temperature, and full metering. They are compatible with a number of different protocols including DeviceNet, Modbus RTU, and Modbus TCP/IP.　　The SR469-P5-HI-A20-E-H is a basic unit with 5 Amp phase CT secondaries. The unit has a control power rating of 90-300 VDC, 70-265 VAC @ 48-62 Hz. Analog outputs are 4-20 mA. The enhanced front panel includes LED indicators, an LCD 40-character display, communication port, and keypad.　　GE Multilin manuals will provide a more in-depth look at this and other SR 469 modules. Datasheets from GE will also give you more information regarding this unit, including handling specifications and particular warnings that should be followed for a safe installation. Related documentation should be reviewed in full before you unbox your part from AX Control.　　Frequently Asked Questions about SR469-P5-HI-A20-E-H

 

 

What is the S3 settings page entered for the SR469-P5-HI-A20-E-H GE relay?　　The S3 settings page is found in the “Control System Requirements” headings and is used for entering digital inputs of characteristics. For most of the digital inputs with the SR469-P5-HI-A20-E-H motor management relay have pre-defined digital functions that can be selected on a list. The user defined digital functions are call “General Switches” A through D and can be found with the assignable inputs that are associated. These input functions need to be set to operate the relays outputs (with or with out delay), have dry contacts that are connected to the digital input terminals and respond to the status changes. To set these functions, you will need to change the names that are defaulted in the system to something you will identify very easily and have meaning behind the names. You can enter these name changes from the LCD or when ever the event reports are being reviewed. Recognize the inputs asserted logics and explain the digital inputs functions. When selecting any of the other pre-defined input functions, you can set them to trigger alarms and trips, and also when needed, energize auxiliary outputs.

What are the settings for the S5 Thermal Model and what does it contain in the settings page for this SR469-P5-HI-A20-E-H motor management relay from GE?

This SR469-P5-HI-A20-E-H Relay has a settings page for protection for the motor while the starting process is turning on, also while the motor is operating normally. These settings can be found in the S5 Thermal Model settings page, the settings for the S5 Thermal Model can be found in the manual for the SR469-P5-HI-A20-E-H Motor Management Relay. Some of the settings are standard, like the curve style selection and the assign trip relays set to “Trip”, but more specific settings should be set to the specific relay you purchased. Please refer to the manual for guidance.

What is the hot and cold curve ratio for this Relay SR469-P5-HI-A20-E?

By using the data sheets from the SR469-P5-HI-A20-E Relay, the safe stall hot and cold time curve ratio is set as 16/18 which is equal to 0.89. The hot and cold curve ratio is simply calculated by dividing the hot safe stall time by the cold safe stall time, the motor thermal limits curve can be used as well.

What is the resistance temperature detector bias maximum rating at for the SR469-P5-HI-A20-E Relay?

The resistance temperature detector bias maximum rating is a settings that is set at the rating for the insulation or set slightly lower. To set the resistance temperature detector maximum bias to a class F insulation is to be rated at 155 degrees celcius in the motor.
