_______________General DescriptionThese microprocessor (µP) supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery-control functions in µP systems. They significantly improve system relia-bility and accuracy compared to separate ICs or discrete components.These devices are designed for use in systems powered by 3.0V or 3.3V supplies. See the selector guide in the back of this data sheet for similar devices designed for 5V systems. The suffixes denote different reset threshold voltages: 3.075V (T), 2.925V (S), and 2.625V (R) (see Reset Threshold section in the Detailed Description ). All these parts are available in 8-pin DIP and SO packages.Functions offered in this series are as follows:________________________ApplicationsBattery-Powered Computers and Controllers Embedded Controllers Intelligent Instruments Automotive SystemsCritical µP Power Monitoring Portable Equipment____________________________Featureso –R —E —S —E —T –and RESET Outputs o Manual Reset Inputo Precision Supply-Voltage Monitor o 200ms Reset Time Delayo Watchdog Timer (1.6sec timeout)o Battery-Backup Power Switching—Battery Can Exceed V CC in Normal Operation o 40µA V CC Supply Current o 1µA Battery Supply Currento Voltage Monitor for Power-Fail or Low-Battery Warningo Guaranteed –R —E —S —E —T –Assertion to V CC = 1V o8-Pin DIP and SO Packages______________Ordering InformationOrdering Information continued on last page.* Contact factory for dice specifications.** These parts offer a choice of reset threshold voltage.

The state of –R —E —S —E —T –or RESET and –P —F —O –is tested at V CC = V CC min.Note 2:Tested at VBATT = 3.6V, V CC = 3.5V and 0V. The battery current will rise to 10µA over a narrow transition window aroundV CC = 1.9V.Note 3:Leakage current into the battery is tested under the worst-case conditions at V CC = 5.5V, VBATT = 1.8V and at V CC = 1.5V,VBATT= 1.0V.Note 4:Guaranteed by design.Note 5:When V SW > V CC > VBATT, V OUT remains connected to V CC until V CC drops below VBATT. The V CC -to-VBATT comparatorhas a small 25mV typical hysteresis to prevent oscillation. For V CC < 1.75V (typ), V OUT switches to VBATT regardless of the voltage on VBATT.Note 6: When VBATT > V CC > V SW , V OUT remains connected to V CC until V CC drops below the battery switch threshold (V SW ).Note 7:V OUT switches from VBATT to V CC when V CC rises above the reset threshold, independent of VBATT. Switchover back toV CC occurs at the exact voltage that causes –R —E —S —E —T –to go high (on the MAX804_/805_, RESET goes low); however switchover occurs 200ms prior to reset.Note 8:The reset threshold tolerance is wider for V CC rising than for V CC falling to accommodate the 10mV typical hysteresis, whichprevents internal oscillation.Note 9:The leakage current into or out of the RESET pin is tested with RESET asserted (RESET output high impedance).ELECTRICAL CHARACTERISTICS (continued)(V CC = 3.17V to 5.5V for the MAX690T/MAX704T/MAX80_T, V CC = 3.02V to 5.5V for the MAX690S/MAX704S/MAX80_S, V CC = 2.72V to 5.5V for the MAX690R/MAX704R/MAX80_R; VBATT = 3.6V; T A = T MIN to T MAX ; unless otherwise noted.

These µP supervisory circuits assert reset to prevent code execution errors during power-up, power-down, brownout conditions, or a watchdog timeout.–R —E —S —E —T –is guaranteed to be a logic low for 0V < V CC <V RST , provided that VBATT is greater than 1V. Withouta backup battery,–R —E —S —E —T –is guaranteed valid for V CC > 1V. Once V CC exceeds the reset threshold, aninternal timer keeps –R —E —S —E —T –low for the reset timeoutperiod; after this interval,–R —E —S —E —T –goes high (Figure 2).If a brownout condition occurs (V CC dips below thereset threshold),–R —E —S —E —T – goes low. Each time –R —E —S —E —T –is asserted, it stays low for the reset timeout period.Any time V CC goes below the reset threshold, the internal timer restarts.The watchdog timer can also initiate a reset. See the Watchdog Input section.The MAX804_/MAX805_ active-high RESET output is open drain, and the inverse of the MAX690_/MAX704_/MAX802_/MAX806_–R —E —S —E —T –output.Reset ThresholdThe MAX690T/MAX704T/MAX805T are intended for 3.3V systems with a ±5% power-supply tolerance and a 10% system tolerance. Except for watchdog faults,reset will not assert as long as the power supply remains above 3.15V (3.3V - 5%). Reset is guaranteed to assert before the power supply falls below 3.0V.The MAX690S/MAX704S/MAX805S are designed for 3.3V ±10% power supplies. Except for watchdog faults, they are guaranteed not to assert reset as long as the supply remains above 3.0V (3.3V - 10%). Reset is guaranteed to assert before the power supply falls below 2.85V (V CC - 14%).The MAX690R/MAX704R/MAX805R are optimized for monitoring 3.0V ±10% power supplies. Reset will not occur until V CC falls below 2.7V (3.0V - 10%), but is guaranteed to occur before the supply falls below 2.59V (3.0V - 14%).The MAX802R/S/T, MAX804R/S/T, and MAX806R/S/T are respectively similar to the MAX690R/S/T,MAX805R/S/T, and MAX704R/S/T, but with tightened reset and power-fail threshold tolerances.3.0V/3.3V Microprocessor Supervisory Circuits 6_____________________________________________________________________________________________________________________________________________________Pin Description1V OUT Supply Output for CMOS RAM. When V CC is above the reset threshold, V OUT isconnected to V CC through a P-channel MOSFET switch. When V CC falls below V SW and VBATT, VBATT connects to V OUT . Connect to V CC if no battery is used.2V CC Main Supply Input 3GND Ground4PFI Power-Fail Input. When PFI is less than V PFT or when V CC falls below V SW , –P —F —O –goeslow; otherwise, –P —F —O –remains high. Connect to ground if unused.7–R —E —S —E —T –Active-Low Reset Output. Pulses low for 200ms when triggered, and stays low wheneverV CC is below the reset threshold or when –M —R –is a logic low. It remains low for 200ms after either V CC rises above the reset threshold, the watchdog triggers a reset, or –M —R –goes from low to high.—–M —R–Manual Reset Input. A logic low on –M —R –asserts reset. Reset remains asserted as long as –M —R –is low and for 200ms after –M —R –returns high. This active-low input has an internal 70µA pull-up current. It can be driven from a TTL or CMOS logic line, or shorted to ground with a switch. Leave open if unused.6WDIWatchdog Input. If WDI remains high or low for 1.6sec, the internal watchdog timer runs out and reset is triggered. The internal watchdog timer clears while reset is asserted or when WDI sees a rising or falling edge. The watchdog function cannot be disabled.5–P —F —O –Power-Fail Output. When PFI is less than V PFT , or V CC falls below V SW , –P —F —O –goes low;otherwise, –P —F —O –remains high. Leave open if unused.8VBATTBackup-Battery Input. When V CC falls below V SW and VBATT, V OUT switches from V CC to VBATT. When V CC rises above the reset threshold, V OUT reconnects to V CC . VBATT may exceed V CC . Connect to V CC if no battery is used.—RESET Active-High, Open-Drain Reset Output is the inverse of –R —E —S —E —T –.NAMEFUNCTIONMAX690MAX80212PIN34——6587MAX804MAX805123476—58—MAX704MAX806Watchdog Input(MAX690_/802_/804_/805_)The watchdog circuit monitors the µP’s activity. If the µP does not toggle the watchdog input (WDI) within 1.6sec,a reset pulse is triggered. The internal 1.6sec timer is cleared by either a reset pulse or by a transition (low-to-high or high-to-low) at WDI. If WDI is tied high or low, a –R —E —S —E —T –pulse is triggered every 1.8sec (t WD plus t RS ).As long as reset is asserted, the timer remains cleared and does not count. As soon as reset is deasserted,the timer starts counting. Unlike the 5V MAX690 family,the watchdog function cannot be disabled.Power-Fail ComparatorThe PFI input is compared to an internal reference. IfPFI is less than V PFT ,–P —F —O –goes low. The power-fail comparator is intended for use as an undervoltage detector to signal a failing power supply. However, the comparator does not need to be dedicated to this function because it is completely separate from the rest of the circuitry.The power-fail comparator turns off and –P —F —O –goes low when V CC falls below V SW on power-down. The power-fail comparator turns on as V CC crosses V SW on power-up. If the comparator is not used, connect PFI toground and leave –P —F —O – unconnected.–P —F —O –may beconnected to –M —R –on the MAX704_/MAX806_ so that a low voltage on PFI will generate a reset (Figure 5b).MAX690T/S/R, 704T/S/R, 802T/S/R, 804–806T/S/R3.0V/3.3V Microprocessor Supervisory Circuits_______________________________________________________________________________________7Figure 1.Block Diagram Figure 2.Timing DiagramM A X 690T /S /R , 704T /S /R , 802T /S /R , 804–806T /S /RBackup-Battery SwitchoverIn the event of a brownout or power failure, it may be necessary to preserve the contents of RAM. With a backup battery installed at VBATT, the devices auto-matically switch RAM to backup power when V CC falls.This family of µP supervisors (designed for 3.3V and 3V systems) doesn’t always connect VBATT to V OUT when VBATT is greater than V CC . VBATT connects to V OUT (through a 140Ωswitch) when V CC is below V SW and VBATT is greater than V CC , or when V CC falls below 1.75V (typ) regardless of the VBATT voltage. This is done to allow the backup battery (e.g., a 3.6V lithium cell) to have a higher voltage than V CC .Switchover at V SW (2.40V) ensures that battery-backup mode is entered before V OUT gets too close to the 2.0V minimum required to reliably retain data in CMOS RAM.Switchover at higher V CC voltages would decrease backup-battery life. When V CC recovers, switchover is deferred until V CC rises above the reset threshold (V RST ) to ensure a stable supply. V OUT is connected to V CC through a 3ΩPMOS power switch.Manual Reset A logic low on –M —R –asserts reset. Reset remains assertedwhile –M —R –is low, and for t WP (200ms) after –M —R –returns high. This input has an internal 70µA pull-up current, soit can be left open if it is not used.–M —R –can be driven with TTL or CMOS logic levels, or with open-drain/collector outputs. Connect a normally open momentary switchfrom –M —R –to GND to create a manual-reset function;external debounce circuitry is not required.__________Applications InformationThese µP supervisory circuits are not short-circuit protected. Shorting V OUT to ground—excluding power-up transients such as charging a decoupling capacitor—destroys the device. Decouple both V CC and VBATT pins to ground by placing 0.1µF capacitors as close to the device as possible.Using a SuperCapas a Backup Power SourceSuperCaps™ are capacitors with extremely high capacitance values (e.g., order of 0.47F) for their size.Figure 3 shows two ways to use a SuperCap as a backup power source. The SuperCap may be connected through a diode to the 3V input (Figure 3a)or, if a 5V supply is also available, the SuperCap may be charged up to the 5V supply (Figure 3b) allowing a longer backup period. Since VBATT can exceed V CC while V CC is above the reset threshold, there are no special precautions when using these µP supervisors with a SuperCap.Operation without a BackupPower SourceThese µP supervisors were designed for battery-backed applications. If a backup battery is not used,connect both VBATT and V OUT to V CC , or use a different µP supervisor such as the MAX706T/S/R or MAX708T/S/R.Replacing the Backup BatteryThe backup power source can be removed while V CC remains valid, if VBATT is decoupled with a 0.1µF capacitor to ground, without danger of triggeringRESET/–R —E —S —E —T –.As long as V CC stays above V SW ,battery-backup mode cannot be entered.Adding Hysteresisto the Power-Fail ComparatorThe power-fail comparator has a typical input hysteresis of 10mV. This is sufficient for most applica-tions where a power-supply line is being monitored through an external voltage divider (see the section Monitoring an Additional Power Supply ).If additional noise margin is desired, connect a resistorbetween –P —F —O –and PFI as shown in Figure 4a. Select the ratio of R1 and R2 such that PFI sees 1.237V (V PFT )when V IN falls to its trip point (V TRIP ). R3 adds the hysteresis and will typically be more than 10 times the value of R1 or R2. The hysteresis window extends both above (V H ) and below (V L ) the original trip point (V TRIP ).3.0V/3.3V Microprocessor Supervisory Circuits 8_______________________________________________________________________________________™ SuperCap is a trademark of Baknor Industries.Connecting an ordinary signal diode in series with R3,as shown in Figure 4b, causes the lower trip point (V L )to coincide with the trip point without hysteresis (V TRIP ),so the entire hysteresis window occurs above V TRIP .This method provides additional noise margin without compromising the accuracy of the power-fail threshold when the monitored voltage is falling. It is useful for accurately detecting when a voltage falls past a threshold.The current through R1 and R2 should be at least 1µA to ensure that the 25nA (max over extended temperature range) PFI input current does not shift the trip point. R3should be larger than 10k Ωso it does not load down the –P —F —O –pin. Capacitor C1 adds additional noise rejection.Monitoring an Additional Power Supply These µP supervisors can monitor either positive or negative supplies using a resistor voltage divider toPFI. –P —F —O –can be used to generate an interrupt to theµP (Figure 5). Connecting –P —F —O – to –M —R –on the MAX704and MAX806 causes reset to assert when the monitored supply goes out of tolerance. Reset remainsasserted as long as –P —F —O –holds –M —R –low, and for 200msafter –P —F —O –goes high.Interfacing to µPswith Bidirectional Reset PinsµPs with bidirectional reset pins, such as the Motorola 68HC11 series, can contend with the MAX690_/MAX704_/MAX802_/MAX806_–R —E —S —E —T –output. If, forexample, the –R —E —S —E —T –output is driven high and the µP wants to pull it low, indeterminate logic levels may result. To correct this, connect a 4.7k Ωresistorbetween the –R —E —S —E —T –output and the µP reset I/O, as inFigure 6. Buffer the –R —E —S —E —T –output to other system components.Negative-Going V CC TransientsWhile issuing resets to the µP during power-up, power-down, and brownout conditions, these supervisors are relatively immune to short-duration negative-going V CC transients (glitches). It is usually undesirable to reset the µP when V CC experiences only small glitches.Figure 7 shows maximum transient duration vs. reset-comparator overdrive, for which reset pulses are not generated. The graph was produced using negative-going V CC pulses, starting at 3.3V and ending below the reset threshold by the magnitude indicated (reset comparator overdrive). The graph shows the maximum pulse width a negative-going V CC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e., goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically,a V CC transient that goes 100mV below the reset threshold and lasts for 40µs or less will not cause a reset pulse to be issued.A 100nF bypass capacitor mounted close to the V CC pin provides additional transient immunity.MAX690T/S/R, 704T/S/R, 802T/S/R, 804–806T/S/R3.0V/3.3V Microprocessor Supervisory Circuits_______________________________________________________________________________________9Figure 3.

Remote Annunciator Controller (RAC) Instruction Sheet for ATC-300+ Controllers Revision: 004 IB140061EN1.0 OverviewThe 7” RAC is a color touch-screen display with easy-to-use functions that provide a powerful interface with up to 8 Automatic Transfer Switches equipped with the ATC-300+ controller (firmware 4.0+ only). It supports serial RS-485 Modbus RTU and Modbus TCP/IP natively. When using Ethernet to connect to an ATC-300+, a serial-to-Ethernet Modbus gateway is required such as the PXG-900 or the ELC-CAENET.The 7” RAC Kit contains the following:HMIVU07CUNBE (7” Color HMI Display)IL04801003E (HMI Instruction Leaflet)IB01602080E (Ethernet Setup Document)ELC-PS01 or 02 (Optional 24VDC power supply)IB140061EN (This Instruction Sheet)66A8395, E, or EM (HMI Wiring Diagram)66A8448H02 (HMI Interconnect Module – serial connections only)2.0 FeaturesThere are three types of features incorporated into the ATC-900 RAC: Status, Control, and Setpoint Editing.Status Indicators•S1 / S2 Available•S1 / S2 Connected•Emergency Inhibit•Lockout / Monitor Mode•Closed on Emergency•Go to Emergency Active•Engine Test Active•Source 1 Voltage Metering•Source 2 Voltage Metering•Waiting for Manual Retransfer•History of Events•Active TimerControl Pushbuttons•Go to Emergency / Cancel Go to Emergency•Start / Stop Engine Test•Alarm Silence•Bypass Timers•Manual Retransfer3.0 Setup and WiringThe RAC requires 24VDC power with a minimum current of 360 mA (See “A” below). There is a terminal block connector on the back of the unit to install wires for the power. The software comes preloaded onto the unit according to your switch configuration, and should require no user programming.The RAC supports Modbus RTU (serial RS-485) and Modbus TCP/IP (Ethernet). However, since the ATC-300 controller only supports serial Modbus, an RS-485 serial-to-Ethernet gateway must be used for Modbus TCP/IP. Eaton recommends using the ELC-CAENET module or a Power Xpert Gateway (PXG-900).Drawing 66A8395 shows the wiring of the unit over serial Modbus. Consult drawing 66A8395E (or EM) when using Ethernet gateways. All RS-485 serial cable must have three insulated conductors (D0, D1, COM) and one ground (drain) connected to the shielding of the cable. The Eaton recommended cable is Belden 3106A. Ethernet cable may be any CAT5/6 certified cable.Depending on the application, a termination resistor should be used if the total transmission line length is over 600 meters. If needed, a 120 Ohm, 0.25 Watt resistor should be installed at the end of the transmission line opposite of the Controller.When the resistor is used, set DIP-switch SW1 on the top-right side of the Controller to the “on” position in order to match the termination.Note: multiple Modbus Ethernet gateways may be used to further expand thecommunication flexibility of the system. Drawing 66A8395EM should be referenced for wiring of multiple gateways.ELC-CAENET Ethernet Gateway PXG-900 Ethernet Gateway3.1 ATC-300 SetupThe communication setpoints on each ATC-300 need to be set as follows: Baud Rate: 9600Address: 01, 02, 03, 04, 05, 06, 07 or 08 (each ATC-300 must be unique) Termination SW1: Normally OFF. Should be ON for last controller in the chainonly if using a 120 Ohm resistor on the opposite end of acommunication daisy-chain.3.2 RAC SetupYour HMI is factory set with communications disabled for all controllers, and must be enabled during startup. To enable communications, press on any disabled controller from the Overview screen (or the “System Setup” button on the Controller screen if you have a single-view HMI). Enter your password (default of 0300). A list of available controller com links will appear. To name a controller, press the “Edit” button next to the corresponding controller. To enable communications to a controller, press the red “Disabled” button under the Coms column; it will change green and display “Enabled”. To disable communications to a controller, press the green “Enabled” button; it will change back red and display “Disabled”. More detail can be seen in section 4.0 below.To change your ATC-300 Setpoints (firmware 4.0+ only), simply press the orange “Edit ATC # Setpoints” button, and you will be taken to the first setpoint screen. See section 4.6 for more details.You can also change items like HMI touch screen force, touch screen calibration, time & date, brightness & contrast, alarm & touch volume, and others. To do this, you have two options:The first is to simply press the small SYSTEM button on the back of the unit for two seconds. The system menu will now be displayed on the screen. The menus are self-explanatory but if additional help is required, consult the manual on the Eaton website called “HMiSoft User Manual” IL04801003E.The second option is to enter the “System Setup” screen again and press the “HMI Setup” button. This is useful if the back of the unit is not easily accessible.4.0 HMI ScreensThe RAC has a total of 6 screens (5 if using single-view firmware). The following is a summary of the available screens and their function:•Overview – In a multi-view system, this shows the status of all controllers at once. This screen is not included if you have a single-view firmware HMI.•Controller View – Presents a more detailed view of a single controller and gives limited control functionality.•Trend Data (S1/S2) – Displays trend data (voltage and frequency) for each of the power sources.•Alarms and Events – Shows the user a time and date-stamped list of certain events and alarms.•System Setup – Allows naming, enabling/disabling coms, and accessing setpoints of each controller along with password and HMI setup.•Controller Setpoints – Allows editing of every available setpoint on the ATC-300 controller.4.1 Overview ScreenThe Overview screen (only available with multi-view firmware HMI) shows the current status of up to 8 ATS-300 controllers running firmware 4.0+. In the example above, Controller 1 is communicating and is waiting for a manual retransfer input. Controller 2 has been placed in Lockout which triggered an alarm. Controller 3 is connected toS1 and has Emergency (S2) Inhibit active. Controllers 4 and 7 have timed out and are trying to reconnect automatically. Controller 6 is connected to S2 and has “Go To S2” enabled. Controllers 5 and 8 are disabled per the user.To view more details and controls for any communicating controller, press anywhere inside the summary window of the desired controller. This will take you to the Controller View screen (section 4.2) for that particular controller.To enable or disable controllers, press on any disabled station and enter your password. See section 4.4 for more information on the System Setup screen.If any controller has an Alarm condition, anaudible alarm will sound from the HMI. Toview the alarm, press on the alarmedcontroller window. Once you are on theController View screen, an alarm popupwindow should be displayed. To silencethe alarm, press “Silence Alarms” button.To close the alarm popup, simply press“Close”.To view the alarm popup window again, press the “ALARMS PRESENT” indicator on the Controller View screen.4.2 Controller View ScreenThe Controller View shows a much more detailed view of a single controller. Note: this will be the default screen for a single-view firmware HMI. The right area contains a status grid with 9 indicators. Status indicators change from gray to yellow or red when active.The left area of the screen contains the Source 1 and Source 2 detail windows. These windowsinclude graphical and numerical representations of voltage and frequency as well as a trend screenbutton (Section 4.5).The voltage and frequencythe source is. The top grey area indicates the Over-voltage orbottom grey area indicates the Under-voltage/frequency drop-out range. The middle light-blue area indicates the “good” range.These areas resize dynamically depending on how the dropouts are set in the ATC-300’s setpoints. If the voltage or frequency reaches the upper or lower ranges, they will turn from grey to red, indicating a problem. Note that the numerical value will change to “N/A” if the value is ever invalid (e.g. Vbc and Vca in a single-phase system.) the acts identically to the mimic bus on the System Overview screen. The upperbanner displays the name of the selected controller. The bus areashows which source is available andconnected. Active lights are white, while inactive lights are black. The currently energized bus is depicted by a light-blue colored line.Active LightTo the bottom right of the mainarea is the Manual Retransferwindow. This area indicateswhether manual retransfer isenabled or disabled, as well asalerting the user if the ATC-300 iswaiting for a manual retransfer signal. The manual retransfer can be initiated remotely by pressing the button labeled “Press to Retransfer” when it appears on the HMI.The bottom area of the screen shows navigation buttons along with the “Show Manual Controls” button. The “Back to Overview” button navigates to the Overview Screen (Section 4.1). Note: this button is not available in the single-controller firmware. The “Event History” button navigates to the Alarm/Events Summary screen (Section 4.3). The “System Setup” button navigates to the System Setup screen (Section 4.4).The “Show Manual Controls” button expands a small area with 3 control buttons: Go to Emergency, Bypass Timers, and Start Engine Test. All control is password protected except Bypass Timers. To hide the manual controls, press the “Hide Manual Controls” button.Engine Test ButtonTo initiate an engine test from the RAC, press the Start Engine Test button and enter your password. The ATC-300 will signal the generator to start. Once the generator has reached nominal voltage, it will run until the Engine Test Run Time expires (adjustable in the ATC-300). If your ATC-300 is programmed for Load Transfer, then it will also transfer your load to the generator during the engine test. To abort the test early, push the Cancel Engine Test button on the RAC.Go to Emergency ButtonTo initiate a go to emergency command from the RAC, press the Go to Emergency button and enter your password. The ATC-300 will initiate a transfer to Source 2. To go back to Source 1, press the Cancel Go to Emergency button. If you have Manual Retransfer enabled, the “Press to Retransfer” button will appear (see below).Manual Retransfer ButtonThe Manual Retransfer button allows the ATC-300 to transfer back to Source 1 at the operators discretion. It functions the same as the physical Manual Retransfer pushbutton located on the ATS front device panel (if equipped). Note: this RAC pushbutton is only visible when the ATC-300 is waiting for a manual retransfer input,otherwise it will not appear. If manual retransfer is disabled on the ATC-300, the button will never be displayed.Bypass Timers ButtonThe Bypass Timers button allows the user to skip a currently active timer. While a timer is counting down, simply press the button, and it will be bypassed. This button works for the following timers:4.3 Alarm and Events ScreenControllerEventsControllerAlarmsThe Alarm and Events screen displays time/date-stamped alarms (in red) and events (in black) for all connected controllers. This information is stored in the HMI’s memory, and will not be erased if the unit is powered down. Therefore, a “Reset History” pushbutton is provided to clear all historical events and alarms if needed. A list of all available messages is shown on the following page.4.4 Trend ScreensThe Trend screens show a graphical representation of Voltage and Frequency. The HMI takes data samples every 1 second for each controller it communicates to. The internal storage of the HMI can store up to 4.6 days of historical data on the single-view firmware, and up to 26 hours on the multi-view firmware. The HMI can beconfigured from the factory to export and store this data on an external USB drive orNavigation SlidersTrend Label Voltage PenOverfreq. LimitUnderfreq. LimitFrequency PenSD card if requested. Additionally, data saved to external devices can be viewed on any PC program that supports CSV files.If applicable, the trend windows also display the Under/Over-Frequency and Voltage limits as set in the ATC-300. These are depicted by red horizontal lines on the trend window.To view trend data on the HMI, simply press the Trend button of the voltage source you wish to view (Source 1 or Source 2). Once on the trend screen, you can go forward and backward through time by using the scroll bar and arrows on the bottom of each trend window. The most recent data is on the right side of the window, while the oldest data is on the left side. To see a data point value at a specific point in time, press on the screen at the desired point and the HMI will draw a vertical line there and display the data value.4.5 System Setup ScreenThe System Setup screen allows the user to type in a name for each ATS controller (up to 8 controllers per RAC in a multi-controller configuration, or 1 controller in a single-controller configuration). Simply press the Edit button next to the controller you wish to name and type in your desired name using the on-screen keyboard. These names will be displayed above each respective controller in the Overview screen. Thecontroller’s name will also be shown while viewing that controller’s Controller View screen.The user may also disable any communication link between the RAC and controller by pressing on the coms enable/disable button for the corresponding controller. When enabled, the display will show a green “Enabled” button; when disabled, the display will show a red “Disabled” button. To toggle the communication state, simply press the button and the state will toggle.HMI SetupThis button opens a menu that allows the operator to change items like touch screen force, touch screen calibration, time & date, brightness & contrast, alarm & touch volume, and others. By default, the HMI should be set up so the user will not have to adjust anything in the field. Specific details on each setting can be found in the HMI Manual (IL04801003E).Password Setup (Popup Menu)As mentioned earlier, passwords are needed to initiate controller functions (Engine Test, Go to Emergency, and Manual Retransfer) and to access the setup menus. If you would like to change the passwords, press the Password Setup button in the Controller Setup screen.Default Password ListThe Operator level (Level 1) applies to operator-related actions, such as initiating an engine test, go to emergency, or manual retransfer, viewing setpoints,enabling/disabling and re-naming controllers. Admin Level (Level 2) allows changing controller setpoints and changing the HMI passwords.If you change your level 2 password, do not forget it or you will be unable to change passwords!4.6 Controller SetpointsThe HMI allows the user to program all ATC-300 controller setpoints remotely for firmware version 4.0 and higher . The setpoints are organized into 4 categories:• System Setup• Time Delays• Dropouts & Pickups (2 pages)• Engine Test & Plant ExerciserValid SetpointRangesTo access your desired category, simply press one of the buttons near the bottom of the screen. The currently active category will turn blue with white text. The Dropouts & Pickups setpoints have more than one page, so you will see a “Next Page” button in the upper-right corner. Pressing this will take you to the next setpoint page in that category. Pressing the “Previous Page” button will take you back to the previous setpoint screen.To change a setpoint, simply press the corresponding setpoint box (white rectangle with blue border) and you will be prompted to enter a new setpoint value. Valid setpoint entries are always shown to the right of the setpoint box. For example, the System Voltage setpoint can be set to 115 (50Hz), or anywhere between 120 and 600. If you are outside the limits, the HMI will display a popup letting you know it was an invalid entry.To return to the Controller Setup menu at any time, press the “Return to Controller Setup” button in the upper-left corner.For more information on any setpoint, consult the ATC-300+ IB (IB01602009E).CAUTIONThis is a remote control device. Caution should be applied to make sure that appropriate procedures are in place for Engine Tests and Remote Transfers. Appropriate procedures include, but are not limited to, switch doors being closed and latched, personnel knowledgeable of transfers, and other site safety recommended procedures.。

为了方便操作，设置如下：External: 1个卷x40GNormal: 3个卷x30GHight: 5个卷x25GFlex: 3个卷x30GOCR+VOLTING+MGMT存储通常放到一个磁盘组，且选择Normal的冗余方式，也即最少3块asm磁盘80G空间。

操作系统安装操作系统安装时把“Server with GUI“和”Compatibility Libraries”勾上，其他都不用选择。

版本采用CentOS 7、RHEL 7或者Oracle Linux 7安装oracle预安装包yum install -y oracle-rdbms-server-12cR1-preinstall创建用户和组oracle用户和dba、oinstall组已经在上一步创建完毕。

rac所有节点的oracle用户和grid用户的uid和gid必须一致，所以创建的时候最好制定uid和gid。
